31 I see. In this case have a look at /proc/config (it may be compressed) or
32 depending on your version of sysrescuecd and kernel choice, have a look here:
33
34 https://sourceforge.net/p/systemrescuecd/code/ci/master/tree/

36 then compare your configuration to theirs. The kernel module for GPT is
37 'CONFIG_EFI_PARTITION' and it must be built in, rather than as a separate
38 module.
