Windows 7: How to change drive letter of Windows installation

How to change drive letter of Windows installation

After replacing my laptop hard drive with a SSD, I decided to install that hard drive into my desktop computer to get the data off it, and eventually use it to expand the storage on my desktop. However there is a conflict of drive letters, as both drives identify themselves as C.

I can get it to work by unplugging one drive, then plugging it back in after windows has booted (that drive is assigned the letter D by windows then) but this is a tedious solution. Is there any software available that will enable to to change the drive letter of either drive?

Go to the desktop and rename the C drive to something like "THE REAL WINDOWS". Shut down, install old laptop drive and boot with Partition Wizard. Go to unnamed drive and remove active flag.

I find it impossible that both drives are being labled C at the same time. Not no way, Not no how.

Not even a Tyrannosaurs.

If you`ve gotten the data off, just format it. It will then grab a new letter and it will never be C again

All I know is having both drives plugged in is causing some sort of conflict in the windows bootloader, causing neither to boot. I assumed it's because both drives were C: in their respective installation. Anyway I've took your advice to just back up the data then format it.

Thanks Everyone for your help
