It also strips off all the unnecessary ones, which will speed up your compilation.

And similarly replace hd0,0 with the value appropriate in your computer's configuration. [ hd0,0 refers to Hard-disk 0, partition 0, that is, the first partition on your first hard disk. ] Once you are able to boot into your OS fully, check your grub entries to see if anything seems to be wrong and fix them. The relevant file would be /boot/grub/menu.lst if you are using the old version of Grub (and not Grub2). Can anyone tell how can I recover my compiled kernel and distro's kernel? > > Regards, Srivatsa S. Bhat
