I am having a weird issue. I decided to reinstall my OS because it was moving way too slow and it was just time for a fresh copy. I have a SATA 2 drive partitioned into 2 drives. One smaller 50 gig that I always use as my OS drive, and one larger 350 gig that I use to store all my data so re installation can be quick and easy. Here is my issue...
When I boot to the Win XP installer it is labeling my OS portion of the drive as the D drive and my data as the C drive. When I install windows then, my Operating system is installed on my D drive along with programs etc. Why is it doing this, and how can I reinstall so my Boot drive is labeled my C drive and my data drive is my D drive?

Thanks All!

Probably a Repair Reinstall of XP would have been your best option, that way the installation would have acquired the existing OP/SYS and repaired it without losing any other data, or even affecting your second partition or redesignating drive letters.

Well if you have an external HDD for backing up important data, now would be a good time to get everything you want to keep backed up to that external HDD, or at least backed up to DVD disks, as long as you can successfully boot into the D drive partition, I'd make that my highest priority at this point before doing another thing.

If someone suggests you rename drive letters at this point you could end up not being able to boot into anything, so first of all back up your data!

Personally my suggestion is backup and start all over again, delete the partitions and recreate them, and reinstall and make sure the proper partition is highlighted that you reinstall the OP/SYS on.
