My PC runs with 4 disk partitions with C(30 GB - Active System Drive), D(140 GB), E and F as drive letters. Now, C drive is showing some problems and it takes too much time to format and install back the OS into it. It seems like some bad sector issue with that drive.

By that reason, I am trying to delete partition C and recreate it once so that bad sectors may be cleared out of it. When, I delete C drive I hope it will make partition D as Active System drive automatically.

But, I wouldn't like to have whole of 140 GB space in partition D as system drive locked state.

I am thinking of two options to avoid this.

  • Delete the partition D first and partition it again as D & X (some other drive) may be of size 30 GB and 110 GB correspondingly. Then delete partition C (which makes D, with 30 GB currently as System Active drive) and recreate partition C again.
  • Delete and recreate partition C first which makes partition C as System Active drive. Then delete and recreate partition D next and hope it will make partition C back as System Active drive (not sure whether deletion of D will make E as System Active Drive).

So among these which is the better way I can follow. OR Is there any much better option possible.


  • I am using Windows XP installation CD's boot option to do these partition changes.
  • Please don't suggest anything which involves partitions E and F. It have a lot of content in those and I don't want to mess with those.

I'm not sure what you mean by the "using Windows XP boot option", but if you have an XP install CD, you should be able to delete and recreate the C: partition before re-installing the OS onto it. –  martineau Sep 29 '12 at 22:24
I'm sorry if the question was not so clear. By "Windows XP boot option" I meant the Windows XP installation CD's boot option. I'll edit the same in the question. –  RinoTom Sep 30 '12 at 7:17
I am not just okay with deletion and recreation of C: partition. I need either C: or D: partition as active system partition after all these changes. –  RinoTom Sep 30 '12 at 8:17
I believe the Windows XP installer will make C: both the system and the boot (or active) partition. If not, you'll likely need to get some third-party disk partitioning utility that can be started from a bootable CD or DVD disc. I've read good things about the EaseUS Partition manager. The answers to this question may be helpful. –  martineau Sep 30 '12 at 16:14
Here's another article with good information (although the title makes it like like it's the opposite of what you want). –  martineau Sep 30 '12 at 16:22
