You need to do that "clean" install idea I mentioned earlier But you need to backup first. You can backup a number of ways One way would be to use a bootable CD like the Ultimate Boot CD, then just use a USB flash reader (or even blank CD) to copy your data off Another option would be to physically remove your harddrive to another computer and attach it as a secondary (not main!) drive, then back up from there Once all is backed up Insert your Windows CD, and then remove all Partitions and continue installing Windows Note: The "remove all the partitions" steps will be shown to you during the Windows setup (sounds as though you may need to remove 3) Edit:/ Sorry forgot to answer your last reply (mainly due to having 3 in a row, can sometimes lose this, without seeing it) You cannot "Merge" or "Delete" posts. Only Moderators can do this If you want to re-reply to your latest reply, use "Edit" instead. Only if yours is still the most recent last post "Edit" is located on the bottom right hand side of all your posts, it is designed to allow you to Add to your last reply (being the last post in a thread) ie A perfect example, is what I'm doing right now, I used "Edit" Because this post is still the last post in the thread .
