Re: GRUB2 and /dev/sdb9p1

[KESHAV P.R.]

You should probably try (hd0,msdos9,msdos1) or simply (hd0,9,1) . I
would suggest the first one. Note - this kind of device naming in
GRUB2 came after 1.98 release. You need to use a bzr version of GRUB2.

Try :-

set root=(hd0,msdos9,msdos1)
chainloader (hd0,msdos9,msdos1)+1
