I have been running HH for several weeks on a HP laptop, dual-booted
with Vista. This morning I used the Synaptic Package Manager to
download and install VirtualBox. After reading the users' manual, it
became obvious that the application wasn't going to do what I wanted,
so I used the Synaptic Package Manager to completely remove
VirtualBox. Now, I can't boot HH. The boot process freezes at the
"Starting Up ..." screen. Once, by pressing the Power key a number of
times, I was able to get it to boot, but it came up in LowRes mode,
claiming it could not find my graphics card. At that point, I booted
to Vista to see if I had a HW problem, but Vista booted with no problems.

I would like to avoid re-installing HH if possible. Can anyone offer
any suggestions?
