In a potential answer (a comment, actually) to this question, there is reference to chainloading using the 40_custom file in grub2. The sample given on the link for chainloading does not work. I suspect it is because of uniqueness in my drive (encrypted, ext3/ext4).



I have been unable to find the documentation on the menuitem entry used in the 40_custom file. I see there are multiple options for referencing the drive (relative position like set root='(hd1)' vs uuid like set root=UUID=XXXX-YYYY).



Anyway, I'm trying to find a page somewhere which documents the options for a menuentry in 40_custom.

  • Not sure what you are looking for, perhaps gnu.org/software/grub/manual/grub/grub.html#Device-syntax see also gnu.org/software/grub/manual/grub
