Grub issues

[jesse205 at gmail.com]

Well, it worked (I got a kernel in place) but I continued having
problems with the bootloader.

It seems that my issue was the stage 1.5 grub image, I got a warning to  
that effect. I Tried to manually boot from the GRUB command line, once I  
had GRUB back in the MBR, but I kept getting kernel panic, so I used the  
above method.

What I ended up doing to get back into my system was a little
painful...

First I installed Ubuntu on the unused partition.

Then I set up internet access, which is not possible for me using
the installation disc.

Then I installed KGRUBEditor and used it to create a new entry, from which  
I was able boot into my old system.
