I have been running Windows 7 on my 'C' drive and then decided to dual boot the machine by putting XP on the 'D' drive. I now have a dual boot machine but when in XP a message pops up about every 5 minutes saying Low Disk Space on the system reserved C drive. Firstly XP is running on 'D' not 'C' and secondly there is plenty of disc space. On the the 'C' drive there is 735GB free on a 1Tb drive and on 'D' there is 459Gb free on a 500Gb drive. As the message pops upevery 5 minutes it is annoying - how do I get rid of it? Thanks for any help.
