I recently (last night actually) installed Windows XP Professional SP3 onto my eMachine. When it was recognizing partitions on my hard disk, it set my system drive as drive letter L: (not the problem).
The problem is setup assigned letter C: to my System Reserve partition, and I can't change it in Disk Management - it says I cannot change the drive letter of my system or boot partition. The problem is it isn't my boot partition (although it is marked as "System".
Is there a way I can force the drive letter off of that partition? Some programs that I install automatically onto my System Reserve partition, and Windows won't let me modify or delete anything on it.
