Reboot and select proper boot device!

I had dual boot, two hard disks, maxtor and seagate, today morning maxtor failed after 9 years, it prompted an error " hard disk is failing this might be the right time to back your data", i backed up all my data and did dos boot seagate scan which showed failed in all the test for maxtor, then i removed it and destroyed the hard disk and now when i boot my pc from seagate which had windows 7 installation it shows reboot and select proper boot device?

i have tired using windows 7 installation disk, windows 7 os does not appear inside system recovery options and startup fix repair does not do anything, i tried all sets of commands in command prompt but that does not do anything, it shows the specified partition is not a primary or logical volume when i set windows 7 partition as active in diskpart

what to do now ? i dont want to reformat

As Brian says you must Mark System Reserved (if you have it) or Win7 Partition Active
then run Startup Repair - Run 3 Separate Times.

If this fails then you may have the OS installed on a Logical Drive which cannot be marked Active. Here's How to set partition as Primary or Logical with Partition Wizard so it can be marked Active and run Repairs.

If none of these work then boot free Partition Wizard Cd (burned to CD with Windows Image Burner) to post back a picture you take of the full drive map and listings fully scrolled. Attach picture using paper clip in Reply Box.

Thanks for helping, I tried everything I could , didn't have another pc with DVD writer to try gparted n partition tools so I just reformated it, it did not install windows 7 on c drive even after formating it, I had to use clean all in diskpart only then it did.
