hi,
I have a (internal) HDD with windows xp (32bit) installed on it. I took it with me to a friend to install windows vista ultimate 64bit on the hard drive, in my friends pc (disconnected his HDD and put in mine, so it was the only one in there).
When i got home i put the drive back in my pc and started it, to my surpise it only started xp.
The partition where i installed it on has 12Gb used, but you can't see anything in windows xp.
I've tried changing the boot.ini file: than when rebooting a option was shown, but when opened, it said there was no OS on the partition...
I have seached the internet for a solution, but all i could find was that vista doesn't use the boot.ini file.
i just went to get the dvd from my friend, but there is something strange: went i try to boot from it, it keeps loading. The loadingscreen (black with the green bar moving) just stays, i've waited 30minutes. When i installed it, it only took maybe a minute or so. I can't seem to find the problem.
The computer should be able to run it:

The problem seems to be something with vista because i just tested if the 32bit version works, but the same result (infinite loadingscreen).
Apparently there has been a vista (home professional) installed on this computer a while ago, so it has to be possible. This vista was uninstalled almost immediately because my brother wanted windows xp back...
Perhaps this Vista wasn't uninstalled correctly and is still in the system. Could there still be a trace of the old vista somewhere in the bootfiles, if yes: where can i find or edit these files?
(other solutions are also welcome)
Thanks already for reading my post, i hope you can help me...
