I have a pendrive with 3 partitions, and it works well but there's one thing that causes troubles. I'm using this pendrive for booting live debian system, but to do this I have to set a boot flag to fist partition, but when I do so, only my laptop can boot the system. My older pc (6-7y) just doesn't see the device, at least in its bios.
Does anyone know why my older pc doesn't see it? Is there a fix for that, or just the bios is so old that can't deal with bootable multipartition usb drive? I just add that the pc has the ability to boot system from usb-hdd. Moreover after doing the following:
# printf '\x1' | cat /usr/lib/syslinux/altmbr.bin - | dd bs=440 count=1 iflag=fullblock conv=notrunc of=/dev/sdb
It boots without a boot flag. I know what that line does, but is there a way to make it work with the boot flag?
