Yes you can, though there are some limitations. Newer Firefoxes (above 64) will have some problems with videos and the address/search bars.

That changes everything. osloader.exe is a modified version of winload.exe which is intended only for MBR/BIOS systems, though you will be able to use the same ntkrnlmp as everyone else. So I checked out winload.efi and it's indeed very similar to the MBR version. So hopefully the patched osloader.efi works. So for UEFI users, just follow this instruction as opposed to the similar one for BIOS users: bcdedit /set {91274567-89ab-cdef-00ff-nca000ffffff} path \Windows\system32\osloader.efi 1 Link to comment Share on other sites More sharing options...

So there seems to be something wrong with my custom osloader.efi. Unfortunately there is no EFI hardware here for me to test it with, so any corrections will take awhile. Does my ntkrnlmp.exe work with the regular winload.efi and nointegritychecks = 1 (yes) in the boot entry? Though this could also be used in theory, but I need to test it: https://github.com/Mattiwatti/EfiGuard Edited September 8, 2020 by win32 Link to comment Share on other sites More sharing options...
