Parallels 5 won't boot Vista

I am on MacOS ver 10.5.8

When starting Parallels 5 I get a black screen with error:

Parallels(r) VGA-Compatible BIOS Version 3.0.2111.89721

6.0.9220.531002 Mon, 02 Nov 2009 17:50:07

1024 MB physical memory installed.
Network bootrom is installed.
Trying to boot from Primary Master IDE drive ...

A disk read error occurred
Press Ctrl+Alt+Del to restart

I press Ctrl+Alt+Del and nothing happens

Any help out there?

Thanks

Have you had any luck because have the same problems after trying to upgrade the RAM on my computer. I use XP and Parallels 5

 

Any luck on fixing this problem as I am having the same issues
Thanks

Nope

I haven't solved this problem.
I am going to see if I can reinstall vista (the version of os I have) if that doesn't work I am going to contact tech support.
