-=== Problems on old BIOS hardware ===
-Some old computers still might not boot since they don't support booting from GPT.
-This can be fixed to boot on such old hardware, however the stick afterwards cannot boot on EFI/UEFI systems anymore:
-*set the boot flag (active) on the single 0xEE partition in the protective MBR by using fdisk version <= 2.22 (versions 1.23 and newer have GPT support and thus don't make changes to the protective MBR but to the GPT) (I used fdisk (util-linux-ng 2.17.2) on a ScientificLinux 6.7 machine)
- fdisk /dev/sdX
- a
- part 1
- w
-*recompute CHS values using option “h” in gdisk's expert menu:
- gdisk /dev/sdX
- x
- h
- m
- q
-this can be reversed:
-- toggle bootflag off in old fdisk
-- recompute CHS values in gdisk
-(using a sgdisk backup of the GPT should also be fine)
-helpful links:
-http://www.rodsbooks.com/gdisk/bios.html#bios --> option h of gdisks experts menu did the trick!
