The BSOD complains that the BIOS is not ACPI compliant. See attached.

I have seen this same BSOD a number of times as well. This has been my process (starting on Tuesday).
1. Download & Install Parallels 4
2. Attempt to convert a virtual machine from v.3 (backing up first, thankfully)--not a Boot Camp partition
3. The process drops me into Manual Mode and asks me to log in--no autologin
4. It asks me to Uninstall Kaspersky, which I do.
5. Reboot Windows, install goes back to splash screen for Step 2 and hangs there for a long time before telling me to go back to Manual mode, where Windows is in an endless loop of restarting, BSOD as in the screen shot quoted, restarting, BSOD, restart...
6. I quit Parallels 4, uninstall, reinstall Parallels 3 and restore my backup.
7. Boot into Parallels 3
8. Uninstall Kaspersky
9. Shut down VM and start Upgrade process all over again at Step 1
10. Same Result (no Step 4 this time).
11. Visit this forum and learn the ctrl-cmd-opt-r keystroke so I can see what's happening behind the splash screen.
12. Have some hope that by seeing what's going on, I can have some impact and make it work.
13. Ignore all messages from Windows about new hardware, etc. I click on the "Upgrade" button in the Parallels Wizard and hope for the best
14. Process seems to be happening. I go back and forth between manual mode and auto mode seemingly at random, but I keep going back to Manual Mode to watch.
15. The Wizard comes up with a button that says "Reboot" so I click it.
16. BSOD as above.
17. Uninstall Parallels 4, restore backup, and get back to work in Parallels 3
Holy moly. This is a cluster*%$*
