Hi,
while I can boot memstick images just fine (which are created using
makefs/mkimg), doing the same thing using gpart/newfs_msdos -F 12/.. I
am not able to get anything that boots.
On a Thinkpad (secure boot is off) from the “boot device chooser from
‘BIOS’” I get a quick blank screen and am back at the chooser.
I’ve tried the gpart “thinkpad hack” as well as trying an MBR (why
that should work I don’t know but the memstick one does) and GPT
options of various kinds.
Anyone successfully done this lately?
