Converted Partion from logical to primary won't boot

I recently converted my hard disk from logical to primary using Partion Magic and now it will not boot, any suggestions as to how i can get it to boot without reformatting?

 

A partition has to be made active to boot. PM should be able to do this, as well as fdisk run in DOS.

 

how do you make a partition active in fdisk

"the following Fdisk Options menu is displayed:

1. Create DOS partition or Logical DOS Drive
2. Set active partition
3. Delete partition or Logical DOS Drive
4. Display partition information
5. Change current fixed disk drive
