Hello all, I have partitioned my hard drive into 3 partitions. I had Windows Vista in C: and Windows 7 in F: and some data in D: partition. I had changed the boot drive to F: and deleted the C: volume. Now the F: drive is system,boot, page file, crash dump, active and primary partition as shown in Disk Management. I would like to change F: to C: drive. Is it enough to do this in Disk Management or do I need to go to registry to do this?Please advise. Teja

You cannot change the drive letter of the boot drive. If you don't like it being F: then the only way to change it is to reinstall Windows 7 on a clean hard drive. You can save you files and settings to transfer to you new installation with Windows Easy Transfer.

Thanks Rick, I would not change after you have advised but could you please tell me the reason for this and one more query: Is it fine if I continue with the same drive letter , I mean there would not any be problem in future for software installations? Teja

I don't have all the detailed information, but it is tied to entries made in the registry and elsewhere during the installation. I actually tried one time with XP to edit all the registry entries to change a drive letter, but all I ended up with was a non-booting disk. And, based on the fact that the situation is not unusual because lots of people dual-boot or multi-boot and it is a vary rare case that it would cause a problem with future installations. Some years back when people first started using hard drives there were some install programs that were hard coded for C: drive, but I think programmers stopped doing that some time back.
