I'm getting the exact same thing, but I have no RAID array. I'm simply
trying to install it on an empty 120gb IDE drive. I've gone through this
about 4 times, and left it last night while I slept to see if it would finish
and it does not. The mouse still works, but there is no HDD activity at all.
I've got the same problem. I've tried it twice and it hangs at the exact
same point of the "completing upgrade" part. No HDD activity, mouse still
works but no way of rebooting without turning off the comp.
Andre's response worked for me. During the reboot right before the
"completing upgrade" happens press f8. Select startup in safe mode, it
should install properly from there. Note: It still took about 30 mins to
complete the completing upgrade portion of the installation. Hope this helps.
