You can add Ventoy to your E2B USB drive.
#Grldr.mbr crucial m4 code
Although it is very easy to use (just add ISOs), it does not always work with all Linux ISOs and often has to contain special code to recognise different distros. Ventoy uses a modified grub2 menu system. YUMI UEFI uses this, but for many payloads it then uses grub2 to get them to work!Ĥ.
#Grldr.mbr crucial m4 iso
The agFM grub2 menu system has an 'Easy2Boot/partnew option' which uses a 'universal' linux ISO boot method.ģ. If a new version of linux is released by the developers tomorrow, it may well not work if it requires different parameters. The problem is that you need to use the correct kernel boot parameters in your grub2 menu file and these parameters will vary from distro to distro and even version to version! This means that you (or the utility that you use to add the linux files to the USB drive), must know the correct parameters for each and every version in the entire world.
#Grldr.mbr crucial m4 install
This means you can have a UEFI grub2 boot menu for each linux ISO so you can 'live boot' to each ISO or install from an ISO. However, certain linux distros can UEFI-boot from an ISO file if you also specify the path of the ISO file in the kernel boot parameters. It has the same problem as mentioned above in that separate partitions are usually required for 'flat file' booting. It can boot via UEFI and also Secure boot to UEFI. grub2- (aka 'grub') is the UEFI boot manager most commonly used by linux distros. WinSetupFromUSB uses the Microsoft EFI version of bootmgr (bootmgfw.efi) to boot to multiple Windows versions only (not UEFI Linux or other UEFI files).Ģ. agFM uses a signed Kaspersky shim which allows us to Secure Boot but then disable Secure Boot so that we can load an unsignded grub2 version and then boot to insecure/unsigned payloads.ġ. E2B REFIND images and E2B grub2 menu system) allow you to boot to unsigned files (or you can use Mok manager to 'whitelist' unsigned boot files, but this makes changes to the system BIOS's NVRAM which can be difficult to remove\change at a later date). When you Secure UEFI-boot, only signed 'secure' EFI files can be loaded and there are not many of these available.
Legacy\CSM boot to E2B) from the USB drive if any EFI boot file is present on the USB drive (on a FAT partition) - the only option presented by the BIOS will be a UEFI-boot option.
This allows you to directly UEFI-boot (even Secure Boot) from the E2B drive and use SWITCH_E2B.exe under WinPE to select any image from the hundreds of. You are prompted to add these when you make a new E2B USB drive.Īn alternative is to switch-in a. The easiest and most versatile way to UEFI-boot is to add a second FAT32 partition containing the agFM boot files.
