Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. boot from FC4 DVD
2. choose either graphical or text installation. Both fail.
3. start package installation
  

Actual Results:  popup "Exception Occured" dialog box

Additional info:

I tried manually changing the partitions to 'ext3' rather than LVM, but then I get a dialog box saying it can't format hda at the same point.

AFAIK, there's nothing wrong with the drive or laptop. Latest Ubuntu installed just fine and I had no problem later restoring Windows XP Home. I'm using the laptop right now. I don't see any options in the BIOS that seem relevent.
