MediCAT In a real use case, when you have several Linux distros (not all of which have Secure Boot support), several unsigned UEFI utilities, it's just easier to temporary disable Secure Boot with SUISBD method. da1: quirks=0x2. I don't remember if the shortcut is ctrl i or ctrl r for grub mode. Ventoy up to 1.0.12 used the /dev/mapper/ventoy approach to boot. Still having issues? Although a .efi file with valid signature is not equivalent to a trusted system. I tested it but trying to boot it will fail with an I/O error. Thank you! Tested on 1.0.57 and 1.0.79. The worst part is, at the NSA level, this is peanuts to implement, and it certainly doesn't require teams of coders or mathematicians trying to figure out a flaw or vulnerability. 3. . The user should be notified when booting an unsigned efi file. @pbatard, have you tested it? see http://tinycorelinux.net/13.x/x86_64/release/ How to mount the ISO partition in Linux after boot ? 1: The Windows 7 USB/DVD Download Tool is not compatible with USB 3.0. If the ISO file name is too long to displayed completely. Maybe I can provide 2 options for the user in the install program or by plugin. It seems the original USB drive was bad after all. Asks for full pathname of shell. It . https://www.youtube.com/watch?v=F5NFuDCZQ00 Ventoy doesn't load the kernel directly inside the ISO file(e.g. To add Ventoy to Easy2Boot v2, download the latest version of Ventoy Windows .ZIP file and drag-and-drop the Ventoy zip file onto the \e2b\Update agFM\Add_Ventoy.cmd file on the 2nd agFM partition. Currently, on x64 systems, Ventoy is able to run when Secure Boot is enabled, through the use of MokManager to enroll the certificate with which Ventoy's EFI executable is signed. Now that Ventoy is installed on your USB drive, you can create a bootable USB drive by simply copying some ISO files onto the USB, no matter if they are Linux distribution ISOs or Windows 10 / 8 / 7 ISO files. You can press left or right arrow keys to scroll the menu. The iso image (prior to modification) works perfectly, and boots using Ventoy. Option 1: Completly by pass the secure boot like the current release. Ventoy can detect GRUB inside ISO file, parse its configuration file and load its boot elements directly, with "linux" GRUB kernel loading command. I've been trying to do something I've done a milliion times before: This has always worked for me. access with key cards) making sure that your safe does get installed there, so that it should give you an extra chance to detect ill intentioned people trying to access its content. So, this is debatable. ", same error during creating windows 7 If that is not the case already, I would also strongly urge everyone to consider the problem not as "People who want Secure Boot should perform extra steps to ensure that only signed executable will boot" but instead as "People who don't care about Secure Boot but have it enabled should either disable Secure Boot or perform extra steps if they want unsigned executables to boot". Seriously? Paragon ExtFS for Windows All the userspace applications don't need to be signed. And, unfortunately, with Ventoy as it stands, this whole trust mechanism is indeed broken, because you can take an official Windows installation ISO, insert a super malicious UEFI bootloader (that performs a Windows installation while also installing malware) and, even if users have Secure Boot enabled (and added Ventoy in Mok manager), they will not be alerted at all that they are running a malicious bootloader, whereas this is the whole point of Secure Boot! Passware.Kit.Forensic.2017.1.1.Win.10-64bit.BootCD.iso - 350 MB Snail LInux , supports UEFI , booting successfully. Just found that MEMZ.iso from https://mega.nz/folder/TI8ECBKY#i89YUsA0rCJp9kTClz3VlA works, file: Windows XP.ver.SP3.English UEFI Secure Boot (SB) is a verification mechanism for ensuring that code launched by a computer's UEFI firmware is trusted. @rderooy try to use newest version, I've been trying on a Dell XPS 13 9360 with Ventoy 1.0.34 UEFI running and Memtest86-4.3.7.iso does not work. Yes. I have this same problem. In this case you must take care about the list and make sure to select the right disk. Select the images files you want to back up on the USB drive and copy them. However, after adding firmware packages Ventoy complains Bootfile not found. Hi, Hiren's Boot CD can be booted by Ventoy in Memdisk mode, you try Ventoy 1.0.08 beta2. The MX21_February_x64.iso seems OK in VirtualBox for me. gsrd90 New Member. Yes, at this point you have the same exact image as I have. Again, it doesn't matter whether you believe it makes sense to have Secure Boot enabled or not. 7. You can grab latest ISO files here : Ventoy version and details of options chosen when making it (Legacy\MBR\reserved space) If someone uses Ventoy with Secure Boot, then Ventoy should not green light UEFI bootloaders that don't comply with Secure Boot. preloader-for-ventoy-prerelease-1.0.40.zip, https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1401532, [issue]: Instead of dm-patch, consider a more secure and upstreamable solution that does not do kernel taint. backbox-7-desktop-amd64.iso - 2.47 GB, emmabuntus-de3-amd64-10.3-1.01.iso - 3.37 GB, pentoo-full-amd64-hardened-2019.2.iso - 4 GB ISO file name (full exact name) Tried the same ISOs in Easy2Boot and they worked for me. @ValdikSS, I'm afraid I am fairly busy right now and, technically for me, investing time on this can be seen as going towards helping a "competing" product (since I am the creator of Rufus, though I genuinely don't have a problem with healthy competition and I'm quite happy to direct folks, who've been asking to produce a version of Rufus with multiboot for years, to use Ventoy instead), whereas I could certainly use that time to improve my own software . Well occasionally send you account related emails. How to Perform a Clean Install of Windows 11. 1.0.84 UEFI www.ventoy.net ===> Help !!!!!!! Open net installer iso using archive manager in Debian (pre-existing system). So even when someone physically unplugs my SSD and installs a malicious bootloader/OS to it, it won't be able to decrypt the main OS partition. arnaud. Will it boot fine? I have installed Ventoy on my USB and I have added ISO file: "Win10SupperLite_TeamOS_Edition.iso" It is pointless to try to enforce Secure Boot from a USB drive. Earlier (2014-2019) official GRUB in Ubuntu and Debian allowed to boot any Linux kernel, even unsigned one, in Secure Boot mode. https://osdn.net/projects/manjaro/storage/kde/, manjaro-kde-20.0-rc3-200422-linux56.iso BOOT And they can boot well when secure boot is enabled, because they use bootmgr.efi directly from Windows iso. All the .efi files may not be booted. list vol - select vol of EFI (in my case nr 14) as illustrated - assign - EFI drive is mounted as Q: Also possible is: After booting with Win10XPE from RAMDISK the Hidden EFI Driv Yes. I don't remember exactly but it said something like it requires to install from an Installation media after the iso booted. It only causes problems. openSUSE-Tumbleweed-XFCE-Live-x86_64-Snapshot20200402-Media - 925 MB, star-kirk-2.1.0-xfce-amd64-live.iso - 518 MB, Porteus-CINNAMON-v5.0rc1-x86_64.iso - 300 MB If you burn the image to a CD, and use a USB CD drive, I bet you find it will install fine. A least, I'd expect that a tutorial that advises a user to modify a JSON file to have done a bit more research into the topic and provide better advice. Maybe because of partition type preloader-for-ventoy-prerelease-1.0.40.zip But this time I get The firmware encountered an unexpected exception. Hey, I have encountered the same problem and I found that after deleting the "System Volume Information" folder on Ventoy partition of the USB disk, it can boot now. The only way to prevent misuse when booting from USB is to set a BIOS password (and perhaps a boot password), set the BIOS to not boot from USB and it won't hurt to also use an encrypted filesystem for the OS on the hard disk (bitlocker/LUKS). Finally, click on "64-bit Download" and it will start downloading Windows 11 from Microsoft's server. Using Ventoy-1.0.08, ubuntudde-20.04-amd64-desktop.iso is still unable to boot under uefi. Mybe the image does not support X64 UEFI! On the other hand, I'm pretty sure that, if you have a Secure Boot capable system, then firmware manufacturers might add a condition that you can only use TPM-based encryption if you also have Secure Boot enabled, as this can help reduce attack vectors against the TPM (by preventing execution of arbitrary code at the early UEFI boot stage, which may make poking around the TPM easier if it has a vulnerability). Tested Distros (Updating) I don't have a IA32 hardware device, so I normally test it in VMware. Option 2: bypass secure boot Do NOT put the file to the 32MB VTOYEFI partition. It looks cool. Hi MFlisar , if you want use that now with HBCD you must extract the iso but the ventoy.dat on the root of the iso recreate the iso with example: ntlite oder oder tools and than you are able to boot from. Maybe the image does not support X64 UEFI" hello everyone Using ventoy, if I try to install the ISO. I will give more clear warning message for unsigned efi file when secure boot is enabled. If you do not see a massive security problem with that, and especially if you are happy to enrol the current version of Ventoy for Secure Boot, without realizing that it actually defeats the whole point of Secure Boot because it can then be used to bypass Secure Boot altogether, then I will suggest that you spend some time reading into trust chains. for the suggestions. Ventoy 1.0.55 is available already for download. Yes, I already understood my mistake. When secure boot is enabled, only .efi/kernel/drivers need to be signed. Reply. Can you add the exactly iso file size and test environment information? Ubuntu.iso). The main issue is that users should at least get some warning that a bootloader failed SB validation when SB is enabled, instead of just letting everything go through. Ventoy also supports BIOS Legacy. @ValdikSS Thanks, I will test it as soon as possible. If a user whitelists Ventoy using MokManager, it's because they want the Ventoy bootloader to run in a Secure Boot environment and want it to only chain load boot loaders that meet the Secure Boot requirements. Go ahead and download Rufus from here. I will not release 1.1.0 until a relatively perfect secure boot solution. Already on GitHub? Agreed. Changed the extension from ".bin" to ".img" according to here & it didn't work. Please refer: About Fuzzy Screen When Booting Window/WinPE. Ventoy2Disk.exe always failed to install ? This is definitely what you want. For me I'm missing Hiren's Boot CD (https://www.hirensbootcd.org/) - it's WindowsPE based and supports UEFI from USB. The program can be used to created bootable USB media from a variety of image formats, including ISO, WIM, IMG and VHD. What exactly is the problem? So that means that Ventoy will need to use a different key indeed. The current release of Slax (slax-64bit-11.2.1.iso) fails to boot using UEFI64 using ventoy with the error message: So any method that allows users to boot their media without having to explicitly disable Secure Boot can be seen as a nice thing to have even if it comes at the price of reducing the overall security of one's computer. Does the iso boot from a VM as a virtual DVD? So the new ISO file can be booted fine in a secure boot enviroment. I still don't know why it shouldn't work even if it's complex. I tested live GeckoLinux STATIC Plasma 152 (based on openSUSE) with ventoy-1.0.15. I've tested it with Microsoft-signed binaries, custom-signed binaries, ubuntu ISO file (which chainloads own shim grub signed with Canonical key) all work fine. The same applies to OS/2, eComStation etc. Code that is subject to such a license that has already been signed might have that signature revoked. But MediCat USB is already open-source, built upon the open-source Ventoy project. Can't try again since I upgraded it using another method. Ventoy2Disk.exe always failed to update ? In this situation, with current Ventoy architecture, nothing will boot (even Fedora ISO), because the validation (and loading) files signed with Shim certificate requires support from the bootloader and every chainloaded .efi file (it uses custom protocol, regular EFI functions can't be used. Perform a scan to check if there are any existing errors on the USB. (This post was last modified: 08-06-2022, 10:49 PM by, (This post was last modified: 08-08-2022, 01:23 PM by, (This post was last modified: 08-08-2022, 05:52 PM by, https://forums.ventoy.net/showthread.phpt=minitool, https://rmprepusb.blogspot.com/2018/11/art-to.html. its okay. That's an improvement, I guess? @ventoy I can confirm this, using the exact same iso. Menu. 4. ext2fsd Win10UEFI+GPTWin10UEFIWin7 Rename it as MemTest86_64.efi (or something similar). For example, Ventoy can be modified to somehow chainload full chain of distros shim grub kernel, or custom validation functions could be made, which would, for example, validate and accept files signed with certificates in DB + a set of custom certificates (like ones embedded in distros' Shims), or even validate and automatically extract Shims embedded certificates and override EFI validation functions (as it's done currently to completely disable validation), but is this kind of complexity worth it for a USB boot utility which is implemented to be simple and convenient? Does it work on these machines (real or emulated) by booting it from a CDR / .iso image? I have installed Ventoy on my USB and I have added some ISO's files : For instance, someone could produce a Windows installation ISO that contains a malicious /efi/boot/bootx64.efi, and, currently, Ventoy will happily boot that ISO even if Secure Boot is enabled. @pbatard Correct me if I'm wrong, but even with physical access, the main point of Secure Boot is to allow TPM to validate the running system before releasing stored keys, isn't it? Hopefully, one of the above solutions help you fix Ventoy if its not working, or youre experiencing booting issues. Some commands in Ventoy grub can modify the contents of the ISO and must be disabled for users to use on their own under secure boot. I've already disabled secure boot. for grub modules, maybe I can pack all the modules into one grub.efi and for other efi files(e.g. If you allow someone physical access to your Secure Boot-enabled system, and you have not disabled USB booting in the BIOS (or booting from CD\DVD), then there is no point in implementing a USB-based Secure Boot loader. Delete the Ventoy secure boot key to fix this issue. Please test and tell your opinion. No bootfile found for UEFI! The point of this issue is that people are under the impression that because Ventoy supports Secure Boot, they will get the same level of "security" booting Secure Boot compliant media through Ventoy as if they had booted that same media directly, which is indeed a fair expectation to have, since the whole point of boot media creation software is to have the converted media behave as close as possible as the original would. This software will repair common computer errors, protect you from file loss, malware, hardware failure and optimize your PC for maximum performance. Point 4 from Microsoft's official Secure Boot signing requirements states: Code submitted for UEFI signing must not be subject to GPLv3 or any license that purports to give someone the right to demand authorization keys to be able to install modified forms of the code on a device. Firstly, I run into the MOKManager screen and enroll the testkey-ventoy.der and reboot. GRUB2, from my experiences does this automatically. Option 3: only run .efi file with valid signature. Not exactly. Windows 7 32-bit does not support UEFI32 - you must use Win7 64-bit.. You may need to disable Secure Boot in your BIOS settings first (or convert the ISO to a .imgPTN23 file using the MPI Tool Kit). First and foremost, disable legacy boot (AKA BIOS emulation). If you get some error screen instead of the above blue screen (for example, Linpus lite xxxx). Oooh, ok, I read up a bit on how PCR registers work during boot, and now it makes much more sense. That's not at all how I see it (and from what I read above also not @ventoy sees it). Yes, anybody can make a UEFI bootloader that chain loads unsigned bootloaders with the express purpose of defeating Secure Boot. lo importante es conocer las diferencias entre uefi y bios y tambien entre gpt y mbr. puedes usar las particiones gpt o mbr. So thanks a ton, @steve6375! And we've already been over whether USB should be treated differently than internal SATA or NVMe (which, in your opinion it should, and which in mine, and I will assert the majority of people who enable Secure Boot, it shouldn't). I can provide an option in ventoy.json for user who want to bypass secure boot. plzz help. ^^ maybe a lenovo / thinkpad / thinkcentre issue ? I suspect that, even as we are not there yet, this is something that we're eventually going to see (but most likely as a choice for the user to install the fully secured or partially secured version of the OS), culminating in OSes where every single binary that runs needs to be signed, and for the certificates those binaries are signed with to be in the chain of trust of OS. However, users have reported issues with Ventoy not working properly and encountering booting issues. Single x64 ISO - OK - Works and install.esd found by Setup - all Editions listed Dual 32+64 ISO - FAIL - Did not find install.esd file (either 64 or 32) \x64\sources\ and \x32\sources in ISO UEFI64 Boot: Single x64 ISO - FAIL - 'No boot file found by UEFI' ' Maybe the image does not support X64 UEFI!' 1. try 1.0.09 beta1? Ventoy does not always work under VBox with some payloads. However the solution is not perfect enough. But I was actually talking about CorePlus. I'm hoping other people can test and report because it will most likely be a few weeks before this can make it to the top of my priority list @ventoy, are you interested in a proper implementation of Secure Boot support? Shim itself is signed with Microsoft key. In this case, only these distros that bootx64.efi was signed with MS's key can be booted.(e.g. The fact that it's also able to check if a signed USB installer wasn't tampered with is just a nice bonus. Is it possible to make a UEFI bootable arch USB? In the install program Ventoy2Disk.exe. I think it's OK. Then user will be clearly told that, in this case only distros whose bootloader signed with valid key can be loaded. Can I reformat the 1st (bigger) partition ? @steve6375 Okay thanks. Click Bootable > Load Boot File. It is designed to protect a system against malicious code being loaded and executed early in the boot process, before the operating system has been loaded. Any progress towards proper secure boot support without using mokmanager? But, considering that I've been trying for the last 5 years to rally people against Microsoft's "no GPLv3 policy" without going anywhere, and that this is what ultimately forced me to rewrite/relicense UEFI:NTFS, I'm not optimistic about it. But Ventoy currently does. la imagen iso,bin, etc debe ser de 64 bits sino no la reconoce The thing is, the Windows injection that Ventoy usse can be applied to an extracted ISO (i.e. You need to make the ISO UEFI64 bootable. Follow the guide below to quickly find a solution. I can guarantee you that if you explain the current situation to the vast majority of Ventoy users who enrolled it in a Secure Boot environment, they will tell you that this is not what they expected at all and that what they want, once enrolled, is for Ventoy to only let through UEFI boot loaders that can be validated for Secure Boot and produce the expected Secure Boot warning for the ones that don't. Anything Debian-based fails to boot for me across two computers and several versions of Ventoy. Heck, in the absolute, if you have the means (And please note here that I'm not saying that any regular Joe, who doesn't already have access to the whole gammut of NSA resources, can do it), you can replace the CPU with your own custom FPGA, and it's pretty much game over, as, apart from easy to defeat matters such as serial number check, your TPM will be designed to work with anything that remotely looks like a CPU, and if you communicate with it like a CPU would, it'll happily help you access whatever data you request such as decrypted disk content. 5. i was test in VMWare 16 for rufus, winsetupusb, yumiits okay, https://drive.google.com/file/d/1_mYChRFanLEdyttDvT-cn6zH0o6KX7Th/view?usp=sharing. Even though I copied the Windows 10 ISO to flash drive, which presumably has a UEFI boot image on it, neither of my Vostros would recognize it. downloaded from: http://old-dos.ru/dl.php?id=15030. I made a larger MEMZ.img and that runs on Easy2Boot and grubfm in VBOX but it goes wrong booting via Ventoy for some reason. WinPE10_8_Sergei_Strelec_x86_x64_2019.12.28_English.iso BOOT but Custom launcher cannot open custom path and unable access to special apps. Guiding you with how-to advice, news and tips to upgrade your tech life. You signed in with another tab or window. For the two bugs. Background Some of us have bad habits when using USB flash drive and often pull it out directly. The latest version of Ventoy, an open source program for Windows and Linux to create bootable media using image file formats such as ISO or WMI, introduces experimental support for the IMG file format.. Ventoy distinguishes itself from other programs of its kind, e.g. When Secure Boot is enabled, BIOS boot (CSM) should not work at all, since it would completely defeat the purpose of only allowing signed executables to boot. if the, When the user is away, clone the encrypted disk and replace their existing CPU with the slightly altered model (after making sure to clone the CPU serial). So, Ventoy can also adopt that driver and support secure boot officially. Great , I also tested it today on Kabylake , Skylake and Haswell platforms , booted quickly and well. You can use these commands to format it: We recommend downloading this PC Repair tool (rated Great on TrustPilot.com) to easily address them. Tested on ASUS K40IN The easiest thing to do if you don't have a UEFI-bootable Memtest86 ISO is to extract the \EFI\BOOT\BOOTX64.efi file and just copy that to your Ventoy drive. By the way, since I do want to bring that message home for people who might be tempted to place a bit too much trust in TPMs, disk encryption and Secure Boot, what the NSA would most likely do, if they wanted to access your encrypted disk data on an x86 PC, is issue a secret executive order to Intel or AMD, to design special version of the CPU they need, where the serial can be altered programmatically (so that they can clone the serial from the original CPU in case the TPM checks it) and that includes additional logic and EPROM to detect and store the critical data (such as disk decryption keys) when accessed. Adding an efi boot file to the directory does not make an iso uefi-bootable. So as @pbatard said, the secure boot solution is a stopgap and that's why Ventoy is still at 1.0.XX. unsigned .efi file still can not be chainloaded. Level 1. And, unless you're going to stand behind every single Ventoy user to explain why you think it shouldn't matter that Ventoy will let any unsigned bootloader through, that's just not going to fly. When install Ventoy, maybe an option for user to choose. For instance, if you download a Windows or Linux ISO, you sure want to find out if someone altered the official bootloader, that was put there by the people who created the ISO, because it might tell you if something was maliciously inserted there. Can't install Windows 7 ISO, no install media found ? Try updating it and see if that fixes the issue.
