Xubuntu fails to boot on dual boot win xp

view full story

http://askubuntu.com – Installed Xbuntu 12.04 on Motion Computing tablet with Win XP as dual-boot. Used GPart to shrink XP partition and created empty 15 GB partition for Xubuntu. Installed from bootable USB stick. All went well. However, at startup, I get choices for Xubuntu, Xubuntu in safe mode, and Windows XP. Can choose win xp and boot into windows, but cannot boot into Xbuntu--with either choice. Get long string of error messages. Any suggestions? (HowTos)
