currently i’m a bit confused. Asking rpm i have grub legacy, grub2 and elilo installed:
ha-idg-1:~ # rpm -qa|grep -i grub
ha-idg-1:~ # rpm -q elilo
I booted the server with UEFI and i have a GPT. How do i find out which boot loader is currently active ?
Ands does SLES 11 SP4 support GRUB2 ? I thought it doesn’t.
Elilo is the supported uefi boot method in SP4 and earlier… (uefi boot has been around for a long time…) all others are legacy boot.
Via YaST bootloader (or look down in /boot/efi/EFI/sles) there will be an elilo.efi file, or as root user run the command;
If you have a gpt disk and boot from it via non-efi then it does a hybrid boot since it can’t write to the mbr.
To boot efi with grub2 you need grub2-efi not just grub2.
Check the output from either gdisk or lsblk and look for a small partition type ef (or ef00) and a /boot/efi partition.
