Because now I get the same error as Wimb did:
bad implemented or the SB option in it is fake SB was included in the specs in 2013 perhaps the laptop firmware made in a hurry by Lenovo is more permissive. IMHO Gerolf is using for his tests a very old Lenovo laptop from 2013 and wimb is using a more modern Asus MB, the very different versions in the UEFI firmware, (based on very different versions of UEFI specs available at the time when each of them were builded), could explain the difference in the findings.
This changed to "Off" after installation of Windows updates (and experiments with Chenall's Universal MBR in legacy mode), but it could easily be set back to "On" when I re-established the default platform key including the certificate for Windows 8 in the firmware setup. efi being chainloaded by Shim and "Grub2EFI", the command msinfo32 told me I was running "BIOS mode: UEFI" in, five lines below, "Secure Boot State: On". After installation of Windows 10/11 and openSUSE Tumbleweed, with bootmgfw. Obviously this happened during my Experiments on GPT/UEFI with grub4dos, grub2, grub4EFI. The DBx list can be easily cleared by going into the UEFI BIOS Setup menu however.Yes.
Windows Update adds a key entry into the UEFI BIOS DBx blacklist which prevents the shim from being loaded if secure boot is enabled. Thank you, Wonko, I agree to the moving of my posts, which applies to this one too, but the objections I want to answer are still at their old places. Note that the grub4efi /ext utilities DO NOT WORK for g4e UEFI32 - this effectively cripples UEFI32 support for grub4efi as hotkey function and all others just crash! I also cannot UEFI32 boot grub4efi when loading bootia32.efi using VBox and QEMU (crashes/reboots).Įdited by steve6375, 17 August 2021 - 07:58 AM. Note that -usb-spec returns the current USB protocol being used which may not be the USB device spec or the USB port spec.

If using both grub4dos and grub4efi on the same partition, you must make two /ext folders (e.g. The only thing missing is support for GPT disks but that may be forthcoming someday.The grub4dos and grub4efi downloads now include a \ext folder which contains utilities which can be run under grub4dos\grub4efi.Īlso the new grub4dos utilities will not run on older versions of grub4dos and vice versa. If you do, then use Google and educate yourself. You don't need to know what Lvyanan or GRUB4DOS MBRs are for Bootice to be useful.
If you install your own disks then you should have this tool. It not meant for the rank novice but should be useful (and educational) to any moderately literate computer user. This is a must-have tool for anyone working with multi-boot systems andor wanting to createuse bootable liverescue systems on USB media but can be used on any disk.
