I installed a beta version of Longhorn a few days ago into a seperate primary partitian I created with acronis. After I messed with it a few hours I decided to uninstall. The problem I have now is when my pc boots up, it goes right into Longhorn OS which isn't there any more, and I get a messge about the ntoskrdnl.exe is missing in WINDOWS root>system32? I checked in this file and I do have it. What I've been doing is when I reboot I have to hit my arrow button real fast while I'm booting up so it cathces XP Pro option on the boot screen. The other two options are "XP Professional orignal", and "Longhorn" I opened up boot notepad in my drive directory to edit and it shows the following: [boot loader] timeout=0 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /KERNEL=kernel1.exe multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional (Original)" /fastdetect I hope I'm explaining myself here.
