Tips for Linux Users
Grub2 can equally be used to carry out the booting.
Many Internet sites have advices on how to make a Grub2 floppy and I have listed one as Task K1 in Just booting tips under my signature. Similarly for making a Grub2 CD please see Task K2.
To boot say second partition of the 4th disk and hide the first one with Grub2 commands at a Grub prompt is simply
Code:
parttool (hd3,1) hidden+
parttool (hd3,2) hidden-
set root=(hd3,2)
chainloader +1
boot
Grub2 count the disk from zero same as Grub1 but for partition Grub1 now counts from 1. Therefore (hd3,1) to Grub1 is equivalent (hd3,2) to Grub2.
In case of doubt use geometry in Grub1 to check the partitions
The equivalent in Grub2 is
which can be used to list the internal directory of / of (hd3,2)
