Windows 7: changing one drive letter all 3 partitions change to that drive letter

The problem is that you converted your HD to Dynamic which is only meant to be used to span a partition across multiple HD's. Apparently you didn't see the warning message.

The solution to solve this non-destructively is to boot free Partition Wizard CD version 4.2 which is the last one which offers this as a free feature: ISO - Windows Live.

Download the ISO, rightclick to burn it to CD using Windows Image Burner, or use ImgBurn.

Boot CD. You will need to delete the extra partition(s) you created which tipped it to convert to Dynamic before it will convert back to Basic.

Then follow these video steps: How to convert dynamic disk to basic disk with Partition Wizard?

If Windows 7 will not start and you confirm it's been converted successfully, then confirm that the 100mb System Reserved partition (preferred if you have it) or C is Set Active partition -Partition Wizard Video Help, then run Startup Repair - Run up to 3 Separate Times.

After conversion if you want help adding a partition post back a screenshot of your maximized Disk Mgmt drive map with listings, using the Snipping Tool in Start Menu, attached using paper clip in Reply Box.

himansh, Would you go into your bios and tell me what your sata controller is set to, Please. It should be set to either, IDE, AHCI or raid. If it is set to raid, that will be your problem. I may be able to help you break the raid volume if it is set to that. Please let us know, before making any changes.
