I have XP and WIndows 7 on my old desktop and since windows 7 is so slow and crashes a lot, how do I go about uninstalling it? Should I just load up XP then format my I:\ drive or do I have to deactivate Windows 7 first?

just click format on it, and set inactive.

It might be that simple - it depends.

If you had XP installed first - XP partition will show as "system" when you are booted into 7.

If that is the case, boot the 7 dvd to command prompt, type:

bootsect /nt52 all

then press enter.

Should then be OK to delete 7 partition.

First, better boot into Win7 and post a screenie of Disk Management , to be sure.

XP was installed first but Windows 7 displays the I:\ drive as "system" as that is the partition it in install in.

Definitely need a screenshot, then.

Should be easy to do once we see it.

Use the Snipping Tool in Start Menu. Attach file using paper clip in Reply Box.
 
I've taken windows 7 out now but I still get the dual boot options screen when I start my PC up. Is there an option to get rid of this?
