Usb boot fails on HP/Compaq if BIOS set up wrong?
I had usb going fine on my Compaq SR 6522 Desktop.
Then I changed some boot order in BIOS and clumsy
as Iam I must have hit something that I should not ahve touched
and now it fail to boot USB. Regardless of which Linux I test.
It simply does not see the USB at all.
so maybe this is wrong forum but I thought others could be helped
if we sort it out?
So I am not alone seems to be a known issue.
But the explanation is on a too high level for me to get.
Could someone please help explain what one are supposed to do?
I quote their answer.
Quote:
The 8200 uses UEFI, not traditional BIOS; in the Boot Order menu, there are submenus titled "EFI Boot Sources" and "Legacy Boot Sources".
One method for USB booting this machine is to disable the EFI boot sources and enable USB Floppy/CD under Legacy boot sources; we're using the Legacy Boot option to set PXE network boot. It should also possible with an EFI-configured USB drive, but I've not tested that.
I don't know how to document what my BIOS looks like. I try to
enter it now and see what it is at. Could someone just give some suggestion what to test?

I failed to find it but made a workaround instead.
F12 does not work. So tested F10 and that put me in BIOS
and I set it to default but it listed no USB anywhere.
So I wild guessed that a USB can be a hard disk group member.
And that where correct only that one had to do Esc instead of
F12 or F10 to get to the start up for the usb and it got listed under
the internal hd.
