I'm trying to repair my broken linux install with grml, since I hear it has EFI support, which I need for what I'm trying to do. Specifically, I need to see a 'UEFI:' prefix before my liveUSB drive when choosing it from the boot menu. So, I downloaded the latest grml ISO, and
dd'd it to my usb (
dd if=grml64-full_2013.02.iso of=/dev/sde), but I'm not seeing the necessary 'UEFI:' prefix from the boot menu.
If my understanding of UEFI/EFI is correct, this happens when the bootloader finds a 'bootx64.efi' file, which is present in my drive (efi/boot/bootx64.efi), but maybe in the wrong location?
Is it possible to get a proper liveUSB with grml2usb? From reading its manpage, I don't see any UEFI/EFI options?
Edit: actually, this is what my GRML liveUSB looks like, according to mount:
/dev/sde1 on /media/grml64-full 2013.02 type iso9660 (ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500,uhelper=udisks) /dev/sde2 on /media/GRML type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=cp437,iocharset=utf8,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks)
And indeed, /dev/sde2 appears to contain nothing but /EFI/BOOT/bootx64.efi
And if it's relevant, my motherboard is an Asus P8P67, which only has UEFI available, my processor is x86_64.
