Hi,
A Dynamic disk is only accessible from the o/s instance that converted it to Dynamic.
I presume you had XP Pro before.
You will need to reinstall your XP Pro on a new simple volume on your basic disk - (using Window's disk management to convert your Dynamic disk back to Basic will cause you to lose all the data on it ). Do check you can access your Dynamic disk from XP after the reinstall.
Then try this :

To convert Dynamic to Basic without losing all your data you could also use Avanquest Partition Commander Pro.

( Avanquest program is about $40 ).Check out the the link first for any instructions before shelling out for it.
If you decide this is the way to go you can get a downloadable version for $15 here
