I've tried a few options that created a flash that is seen as
a UEFI boot flash, but putting the iso image as some use
or the kernel and ramdisk files in places examples show,
it boots, and I can select but get blank screens or error
messages that don't give info. Should have documented
all of that, but once something failed went on to try other
options.
Give up trying to use grub2-install, it doesn’t do what you need it to do.
UEFI boots off EFI executables on a fat32 volume, you don’t need to install special sectors on the beginning of the disk, so you don’t really need to run fancy commands, just ‘cp’.
Seen some post on Windows 11 hardware requirements,
and it might soon make only secure boot a requirement
for anyone.
The UEFI spec says that on x86_64 systems you should be able to
disable secure boot. Dell most likely has that option, because they
have a lot of customers who need it. (for example, if you use nvidia
and CUDA, you'll need to disable secure boot or manually install your
own signing keys)
Think Disabling the Secure boot is not an issue. Person has Dell 3070 machines that allow for the regular USB boot, but just got 140 new Dell 3080 machines, and they seem to have completely elimanated the option??
According to the manual:
Make sure you have USB boot enabled:
Under “USB configuration. Also, according to this:
Hitting F12 will list all *valid* boot options. Most likely your boot disk isn’t valid if you have USB boot enabled.
