I felt compelled to post this as I know many people have had the same
issue so apologies if it has already been done.
I've been trying to install Vista x64 for 1 week now! Every time the
installation would freeze at 'expanding files 5%...'
After trying every possible combination of bios settings and DVD and
HDDs I have found a solution!
1. Upgrade and set BIOS to defaults
2. In BIOS disable anything that varies the CPU or RAM voltages e.g.
Cool & Quiet.
Disable USB, Firewire, onboard LAN, onboard audio (pretty much
anything not absolutely essential to the install, I performed the
install without a mouse!)
3. Set DVD drive to slave
4.Cross your fingers.
Worked a treat for me, entire installation from boot to disc out was 13
mins 35 secs!
Good luck
