Hello,
I will make a boot disk, that can boot from older Hardware with BIOS boot & newer hardware with EFI boot.
My idea is:
Partition1: EFI Boot partition
/EFI/BOOT/ BOOTia32.efi
/EFI/BOOT/ BOOTx64.efi
...
/syslinux/ldlinux.sys
...
Partition2: Linux System
...
...
Also set EFI Boot Partition as active.
Witch BIN file must I install on MBR ?
I think mbr.bin ist the correct.
For PBR (Partition Bootrecord) I use ldlinux.bss.
But is this compatible with the EFI Boot FAT Partition ?
Is there a way to do this, or must I patch syslinux ?
Best regards
Johann
