Hi,
I tried to manually chainload UEFI shell from grub2 terminal in
x86_64 firmware. I get
> insmod part_gpt
> insmod fat
> chainloader (hd0,gpt1)/shellx64.efi
error: not a valid root device
If I use
> set pager=1
> set debug=all
> chainloader (hd0,gpt1)/shellx64.efi
[long rows of text - but no visible error]
> boot
[shell launched]
However a menuentry like
menuentry "UEFI Shell" {
search --fs-uuid --no-floppy --set=root ${_uefi_sys_fs_uuid}
chainloader (${root})/shellx64.efi
}
works. I can reproduce this error everytime I try to manually
chainload from grub2 terminal, but does not occur even once when
loaded via menuentry. Thanks in advance.
Regards.
Keshav
