I'm experiencing a GRUB boot error on my laptop (HP Pavilion dv5z) which reads:
GRUB loading stage 1.5
GRUB loading, please wait...
Error 21
There is one hard drive installed in my laptop, which contains only Ubuntu (Jaunty). The error starting occurring after I performed a clean install of Ubuntu.
Any help is appreciated.
Below I've posted the results of a boot info script that I ran while using the live CD.
