New version of Rescuezilla (2.4) not working properly. Just some of my thoughts: Would MS sign boot code which can change memory/inject user files, write sectors, etc.? No bootfile found for UEFI, maybe the image doesnt support ia32 uefi error, asus t100ta Kinda solved: Cant install arch, but can install linux mint 64 bit. Again, detecting malicious bootloaders, from any media, is not a bonus. These WinPE have different user scripts inside the ISO files. It should be the default of Ventoy, which is the point of this issue. . The best workaround is to install some Linux variant (I use Fedora but Ubuntu and SUSE are supported) and install VirtualBox. You are receiving this because you commented. The live folder is similar to Debian live. Its also a bit faster than openbsd, at least from my experience. Fedora-Workstation-Live-x86_64-32-1.6.iso: Works fine, all hard drive can be properly detected. You were able to use TPM for disk encryption long before Secure Boot, and rightfully so, since the process of storing and using data encryption keys is completely different from the process of storing and using trust chain keys to validate binary executables (being able to decrypt something is very different from being able to trust something). maybe that's changed, or perhaps if there's a setting somewhere to Thank you! Let the user access their computer (fat chance they're going to remove the heatsink and thermal paste to see if their CPU was changed, especially if, as far as they are concerned, no change as occurred and both the computer appearance and behaviour are indistinguishable from usual). @adrian15, could you tell us your progress on this? Set the VM to UEFI mode and connect the ISO file directly to the VM and boot. Many thanks! However, I would say that, if you are already running "arbritrary" code in UEFI mode to display a user message, while Secure Boot is enabled, then you should be able to craft your own LoadImage()/StarImage() that doesn't go through SB validation (by copying the LoadImage()/StarImage() code from the EDK2 and removing the validation part). But, UEFI:NTFS is not a SHIM and that's actually the reason why it could be signed by Microsoft (once I switched the bootloader license from GPLv3+ to GPLv2+ and rewrote a UEFI driver derived from GPLv2+ code, which I am definitely not happy at all about), because, in a Secure Boot enabled environment, it can not be used to chain load anything that isn't itself Secure Boot signed. FFS I just spent hours reinstalling arch just to get this in the end archlinux-2021.06.01-x86_64.iso with Ventoy 1.0.47 boots for me on Lenovo IdeaPad 300 UEFI64 boot. Just right-click on "This PC" on the desktop, select "Manage", and click on "Disk Management . If Secure Boot is enabled, signature validation of any chain loaded, If the signature validation fails (i.e. Maybe I can get Ventoy's grub signed with MS key. 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. 04-23-2021 02:00 PM. Will there be any? We recommend downloading this PC Repair tool (rated Great on TrustPilot.com) to easily address them. Yes ! @pbatard Sorry, I should have explained my position clearer - I fully agree that the Secure Boot bypass Ventoy uses is not secure, and I'm not using Ventoy exactly because of it. This filesystem offers better compatibility with Window OS, macOS, and Linux. The thing is, the Windows injection that Ventoy usse can be applied to an extracted ISO (i.e. Aporteus which is Arch Linux based version of Porteus , is best , fastest and greatest distro i ever met , it's fully modular , supports bleeding edge techs like zstd , have a tool to very easily compile and use latest version of released or RC kernel directly from kernel.org ( Kernel Builder ) , have a tool to generate daily fresh ISO so all the packages are daily and fresh ( Aporteus ISO Builder ) , you can have multi desktops on a ISO and on boot select whatever you like , it has naturally Copy to RAM feature with flag to copy specific modules only so linux run at huge speed , a lot of tools and softwares along side mini size ISO , and it use very very low ram and ISO size, You can generate ISO with whatever language you like to distro have. Yep, the Rescuezilla v2.4 thing is not a problem with Ventoy. You can press left or right arrow keys to scroll the menu. @shasheene of Rescuezilla knows about the problem and they are investigating. However, Ventoy can be affected by anti-virus software and protection programs. Secure Boot is tricky to deal with and can (rightfully) be seen as a major inconvenience instead of yet another usually desireable line of defence against malware (but by all means not a panacea). # Archlinux minimal Install with btrfs ## Introduction If you don't know about Arch Linux, and willing to learn, then check this post, - [Arch Linux](https://wiki . 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). You can install Ventoy to USB drive, Removable HD, SD Card, SATA HDD, SSD, NVMe . Minor one: when you try to start unsigned .efi executable, error message is shown for a very brief time and quickly disappears. 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. @pbatard 5. extservice
But, currently, that is not the case at all, which means that, independently of the merits of Secure Boot for this or that type of media (which is a completely different debate altogether), there is a breach of the security contract that the user expects to see enforced and therefore something that needs to be addressed. I can confirm it was the reason for some ISOs to not boot (ChimeraOS, Manjaro Gnome). In the install program Ventoy2Disk.exe. Tested ISO: https://github.com/rescuezilla/rescuezilla/releases/download/2.4/rescuezilla-2.4-64bit.jammy.iso. plist file using ProperTree. It seems the original USB drive was bad after all. and windows password recovery BootCD How did you get it to be listed by Ventoy? Boots, but cannot find root device. (I updated to the latest version of Ventoy). It's the job of Ventoy's custom GRUB to ensure that what is being chainloaded is Secure Boot compliant because that's what users will expect from a trustworthy boot application in a Secure Boot environment. Thanks a lot. The BIOS decides to boot Ventoy in Legacy BIOS mode or in UEFI mode. And, for any of this to work, Ventoy would still need to independently solve the problem of allowing unsigned bootloaders pass through when Secure Boot is enabled @ventoy Maybe the image does not support X64 UEFI" hello everyone Using ventoy, if I try to install the ISO. It was actually quite the struggle to get to that stage (expensive too!) memz.mp4. Of course , Added. Yes, Ventoy does work within UEFI mode and offers a default secure boot feature. Please refer When Ventoy2Disk.exe Failed to Install, Please refer When Ventoy2Disk.exe Fail to Update, Yes. Turned out archlinux-2021.06.01-x86_64 is not compatible. Follow the urls bellow to clone the git repository. debes desactivar secure boot en el bios-uefi If your PC is unable to process Ventoy as bootable media, then you may need to disable secure boot. Well occasionally send you account related emails. You can put a file with name .ventoyignore in the specific directory. No bootfile found for UEFI! 1. The error sits 45 cm away from the screen, haha. But unless it exploits a Secure Boot vulnerability or limitation (or you get cozy with the folks controlling shim keys), that bootloader should require to be enrolled to pass Secure Boot validation, in the same manner as Ventoy does it. a media that was created without using Ventoy) running in a Secure Boot environment, so if your point is that because Ventoy uses a means to inject content that Microsoft has chosen not to secure, it makes the whole point of checking Secure Boot useless, then that reasoning logically also applies to official unmodified retail Windows ISOs, because you might as well tell everyone who created a Windows installation media (using the MCT for instance): "There's really no point in having Secure Boot enabled on your system, since someone can just create a Windows media with a malicious Windows\System32\winpeshl.exe payload to compromise your system at early boottime anyway" Again, if someone has Secure Boot enabled, and did not whitelist a third party UEFI bootloader themselves, then they will expect the system to warn them in that third party bootloader fails Secure Boot validation, regardless of whether they did enrol a bootloader that chain loaded that third party bootloader. Don't get me wrong, I understand your concerns and support your position. It should be specially noted that, no matter USB drive or local disk, all the data will be lost after install Ventoy, please be very careful. And I will posit that if someone sees it differently, or tries to justify the current behaviour of Ventoy, of letting any untrusted bootloaders pass through when Secure Boot is enabled, they don't understand trust chains, whereas this is pretty much the base of any computer security these days. Will it boot fine? 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). I remember that @adrian15 tried to create a sets of fully trusted chainload chains I have used OSFMount to convert the img file of memtest v8 to iso but I have encountered the same issue. It also happens when running Ventoy in QEMU. Can't say for others, but I made Super UEFIinSecureBoot Disk with that exact purpose: to bypass Secure Boot validation policy. Worked fine for me on my Thinkpad T420. Level 1. You can reformat it with FAT32/NTFS/UDF/XFS/Ext2/Ext3/Ext4 filesystem, the only request is that Cluster Size must greater than or equal to 2048. @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? the main point of Secure Boot is to allow TPM to validate the running system before releasing stored keys, isn't it? So all Ventoy's behavior doesn't change the secure boot policy. If the secure boot is enabled in the BIOS, the following screen should be displayed when boot Ventoy at thte first time. This will disable validation policy override, making Secure Book work as desired: it will load only signed files (+ files signed with SHIM MOK key). Please thoroughly test the archive and give your feedback, what works and what don't. @ventoy I can confirm this, using the exact same iso. 2There are two methods: Enroll Key and Enroll Hash, use whichever one. Option 3: only run .efi file with valid signature. I will test it in a realmachine later. Help !!!!!!! But MediCat USB is already open-source, built upon the open-source Ventoy project. Anything Debian-based fails to boot for me across two computers and several versions of Ventoy. @ventoy Test these ISO files with Vmware firstly. Please refer: About Fuzzy Screen When Booting Window/WinPE. edited edited edited edited Sign up for free . This file is not signed by Microsoft for 'Secure Boot' - do you still wish to boot from it? However, I'm not sure whether chainloading of shims are allowed, and how it would work if you try to load for example Ubuntu when you already have Fedora's shim loaded. I'll try looking into the changelog on the deb package and see if I tested Manjaro ISO KDE X64. git clone git clone ", https://drive.google.com/file/d/1_mYChRFanLEdyttDvT-cn6zH0o6KX7Th/view Most of modern computers come with Secure Boot enabled by default, which is a requirement for Windows 10 certification process. No bootfile found for UEFI! to be used in Super GRUB2 Disk. If anyone has Secure Boot enabled, there should be no scenario where an unsigned bootloader gets executed without at least a big red warning, even if the user indicated that they were okay with that. size 5580453888 bytes (5,58 GB) Guid For Ventoy With Secure Boot in UEFI 1All the steps bellow only need to be done once for each computer when booting Ventoy at the first time. Rufus or WoeUSB, in several meaningful ways.The program does not extract ISO images or other image formats to the USB drive but . what is the working solution? 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. Personally, I don't have much of an issue with Ventoy using the current approach as a stopgap solution, as long as it is agreed that this is only a stopgap, since it comes with a huge drawback, and that a better solution (validation of that the UEFI bootloaders chain loaded from GRUB pass Secure Boot validation when Secure Boot has been enabled by the user) needs to be implemented in the long run. gsrd90 New Member. Hiren's BootCD Go ahead and download Rufus from here. https://www.youtube.com/watch?v=F5NFuDCZQ00 When secure boot is enabled, only .efi/kernel/drivers need to be signed. I'm not sure how Ventoy can make use of that boot process, because, in a Secure Boot enabled environment, all UEFI:NTFS accomplishes is that it allows you to chain load a Secure Boot signed UEFI boot loader from an NTFS partition, and that's it. 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. Rik. Once here, scroll down and move to the "Download Windows 11 Disk Image (ISO) for x64 devices" section. Option 2: bypass secure boot This ISO file doesn't change the secure boot policy. I made a VHD of an arch installation and installed the vtoyboot mod and it keeps on giving me the no UEFI error. Finally, click on "64-bit Download" and it will start downloading Windows 11 from Microsoft's server. I don't know why. 2. . There are many kinds of WinPE. I have the same error, I can boot from the same usb, the same iso file and the same Ventoy on asus vivobook but not on asus ROG. I have a solution for this. Rename it as MemTest86_64.efi (or something similar). You answer my questions and then I will answer yours MEMZ.img was listed with no changes for me. I remember that @adrian15 tried to create a sets of fully trusted chainload chains to be used in Super GRUB2 Disk. Does it work on these machines (real or emulated) by booting it from a CDR / .iso image? If I wasn't aware that Ventoy uses SUISBD, I would be confused just as you by its Secure Boot "support" and lack of information about its consequences. Also tested on Lenovo IdeaPad 300 16GB OK (UEFI64). That would be my preference, because someone who wants to bypass Secure Boot indiscriminately, without disabling Secure Boot altogether, should have a clue what they are doing, and the problem with presenting options as a dialog is that you end up with tutorials that advise users to pick the less secure option, because whoever wrote happened to find the other choices inconvenient without giving much thought about the end result. You signed in with another tab or window. You don't need anything special to create a UEFI bootable Arch USB. Have a question about this project? @BxOxSxS Please test these ISO files in Virtual Machine (e.g. Exactly. Feedback is welcome If your tested hardware or image file is not listed here, please tell me and I will be glad to add it to the table here. However, some ISO files dont support UEFI mode so booting those files in UEFI will not work. Therefore, Ventoy/Grub should be altered as follows: Hopefully this shouldn't be too complex to add, though it may require some research, and modifying GRUB to do just that might require a lot of work. 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. Joined Jul 18, 2020 Messages 4 Trophies 0 . - . 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? Currently there is only a Secure boot support option for check. @pbatard I'm considering two ways for user to select option 1. Ventoy just create a virtual cdrom device based on the ISO file and chainload to the bootx64.efi/shim.efi inside the ISO file. So, yeah, if you have access to to the hardware, then Secure Boot, TPM or whatever security measure you currently have on consumer-grade products, is pretty much useless because, as long as you can swap hardware components around, or even touch the hardware (to glitch the RAM for instance), then unless the TPM comes with an X-Ray machine that can scan and compare hardware components, you're going to have a very hard time plugging all the many holes through which a dedicated attacker can gain access to your data. I was just objecting to your claim that Secure Boot is useless when someone has physical access to the device, which I don't think is true, as it is still (afaik) required for TPM-based encryption to work correctly. But Ventoy currently does. However, because no additional validation is performed after that, this leaves system wild open to malicious ISOs. @ValdikSS, I'm not seeing much being debated, when the link you point to appears to indicate that pretty much everybody is in agreement that loading unsigned kernels from GRUB, in a Secure Boot environment, is a bug (hence why it was reported as such). So that means that Ventoy will need to use a different key indeed. TPM encryption has historically been independent of Secure Boot. Great , I also tested it today on Kabylake , Skylake and Haswell platforms , booted quickly and well. 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 This could be useful for data recovery, OS re-installation, or just for booting from USB without thinking about additional steps. da1: quirks=0x2
