hei, i've got EXACTLY the same problem
After looking into the help section of leopard it says :
Issue or symptom
If you attempt to install Microsoft Windows XP without first formatting a partition, this alert message will appear in Windows XP:
"Press any key to boot from CD. Disk Error. Press any key to restart".
Products affected
- Mac OS X 10.5 Leopard
- Boot Camp 2.0
- Windows XP (any version)
Solution
After creating a Windows partition in Boot Camp 2.0 in Mac OS X 10.5, then rebooting from the Windows XP installer CD, be sure that you format the Windows partition before continuing with the rest of the Windows XP setup process.
Important: Do not use the option named "Leave the current file system intact (no changes)".
Well, the one thing is, I don't see the option to just reformat the partition, just deleting it and making a new one. After I did reformatted and let the first part of the installer run over the partition, my mac rebooted and gave me the message:
Missing file hal.dll .. blablabla reinstall
now whats that supposed to mean after a fresh install? does my mac wanna tell me, "try to install windows again, and I'll play hal2000 and kill you?"
Used a legit University Windows XP Professional SP2 which I bought just for boot camp
(It doesn't need CD key and is legit as long as I am in the University, doesn't matter if student or professor)
What now? I just want Windows on my iMac so i can start it in one of the 4 spaces of leopard so i can switch between os x and windows
(somebody told me this is possible)
