I have a 160GB drive and a 2TB drive (both internal) on a HP xw8200
I have windows xp on the 160 GB drive. 
partitioned a /boot 1GB, 10GB swap, 100GB /, and a 400GB /home on the 2TB drive.
Chose to install Ubuntu 12.04 alongside XP, but just before the installation was complete, error about grub not being able to install.

Tried boot-repair, but still cannot boot into Ubuntu.
Pls. find details at <http://paste.ubuntu.com/998508/>

Your help would be greatly appreciated,
