I have a system running XP. I partitioned my drive in half and installed Windows 7. I tried to start XP again and messed it up. I think it's trying to use XPs boot manager. Do I need to re-install 7 to use it's boot manager?

Now that I know this .iso works great, I want to put 7 on a partition on my main Vista system. I can't afford to lose everything like I did on the XP system. When I tried to start XP after installing 7 I got an error. "windows root system32 hal.dll is missing or corrupt"

I can't have that happening to my main system. Is this normal? Did I do something wrong? Will it happen to Vista? Thanks for any advice.

P.S. Windows 7 build 7048-0-090219-1845 is VERY nice and runs good with 512MB of ram!

Hello again Nate.

I have already answered you to the other post. Now, if Windows 7 starts, then its not using XP boot manager, but the Windows 7 one. (Otherwise Windows 7 wouldn't start).

Check your other post and see if my instructions help.
