Public bug reported:
Binary package hint: grub
10.10 64 bit installed from usb created using 10.04 64 bit & 10.10 final
iso (kernel 2.6.35-22)
grub.cfg contains references:
insmod part_msdos
&
set root='(hd0,msdos8)'
even though my partition is ext4. These lines are not present / are
different in 10.04
When I updated to kernel 2.6.35-25 via update manager, the same grub.cfg
was generated - i.e. no reference to kernel 2.6.35-25, just the
2.6.35-25
grub.cfg contents:
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
