Usb boot probleme on Acer aspire 3 a315-41


Look what I found on acer forum:

"OS must be x64 bit version and EFI compatible.

USB flash drive must have GPT partition scheme and be FAT32 formatted."


That part seems to fall into what @jimbygh posted above, no? He has steps where he ran gpart


so, that’s interesting. they require a GPT partition scheme.

in this case it may be the bios sees a ‘corrupt’ GPT scheme and decides not to boot it.

try this: (recall to use the correct device id - da0 is just an example)

gpart recover da0

then do a

gpart show da0

the “CORRUPT” designation should go away.

try to boot it and let us know!
