[NTLUG:Discuss] Grub assistance

[Stuart Johnston]

If you really want to skip the rescue CD, it sounds like you already 
know exactly what you need to do.  I've never tried this myself (and I 
guess no one else on the list has either) so I can't give you any more 
reassurance than "this sounds reasonable".

Why not give it a try and then enlighten us all?  One of the nice things 
about Grub is that you can easily change your boot options directly from 
the boot loader so if you screw-up your conf file, you're not totally 
screwed.

Here's an article on grub I happened across that looks pretty good:

Then, even if you can't work it out with grub, there is always the 
rescue disk option.  And, of course, back up all your data before you do 
anything.

Good luck!
