I had to install Win XP Pro first and then upgrade in order to keep my activation.
I didn't do anything special about partition. There is a possibility that partition wasn't aligned optimally.
For 2 months, I experienced quite a handful of anomalies. A lot of chkdsk requests on starting. Then, problems with slow Office 2010 specially Access. The windows of Windows 7 features (optionalfeatures.exe) was blank (solved) and then yesterday Windows Media Center quit working, no matter I followed various instructions on internet.
So I am on the verge of reinstalling AGAIN. 3rd time.
I read that I should be using DISKPART to clean and redo the partition.
How do exactly I proceed? Can I do it directly from a commsnf windows (with admin privileges) from my Windows 7 before I put back my Win XP Pro installation CD? Or do I have to put that utility on a CD/DVD/USB or even my 2nd hard drive?
I read a few versions (not always precise) on internet but I the partition part is still very nebulous to me. I tried LIST DISK in DISPART mode (from my current installation) and here is the result.
DISKPART> list disk
