itsallmac.com — Some people are having problems upgrading their Tiger installs to Leopard. After a "successful" install, the mac reboots and hangs at the blue prelogin screen. The Leopard install is apparently hosed. This happened to me too and I had to wipe the drive and reinstall. Thank goodness I had a backup. Seems like a pretty big bug.

Just wanted to give my upgrade story...I have installed Leopard, and didn't see the options mentioned in this post. Instead, when I popped in the DVD and double clicked Install Leopard in my 10.4 install, it rebooted and proceeded to do an upgrade. I had the problems described in the link above with the blue screen after upgrade that just hung out there.So I had to reinstall - I run the disk again and don't see the options to do an erase and install. Instead, I have to use disk utility to blow away my hard drive first. I was still having problems wiping the drive, and had to delete the bootcamp partition first, then wipe the rest of the drive. I think this bug might be related to the bootcamp betas. Thank goodness I had a SuperDuper backup, and I migrated my data at the end of the install. All running now.

This problem appears to be an unfortunate incompatibility with ShapeShifter software you might have installed. Do this and it fixes it (worked for me)1. Reboot into single-user mode (hold Cmd-S while booting machine)2. Follow the directions OSX gives you when you get to the prompt (I think these were them - just type the two commands it tells you to):fsck -fy //sbin/mount -uw /3. Remove the following files:rm -rf /Library/Preference Panes/Application Enhancer.prefpanerm -rf /Library/Frameworks/Application Enhancer.frameworkrm -rf /System/Library/SystemConfiguration/Application Enhancer.bundlerm -f /Library/Preferences/com.unsanity.ape.plist4. Exit, to continue booting normallyexit

Confirmed, this solved the problem for me too. I was hung at the blue screen after the upgrade, but after following the instructions posted by indiekiduk, I booted into Leopard without any further problems.
