Windows 7: Changing C: drive

Changing C: drive

Somewhere along the line in loading Win 7 over Vista the C:drive has been designated as the D drive. When I try to change it with disk mgt. I get the error that I do not have the proper parameter. I have no problem using it as is and on the desktop it shows at C: but would prefer that I can make this change.The HD has been proportioned into 3 drives and the other two are easily changed if I wish.

If I may ask, what is the reason you are using "Dynamic" partitions?

Vista and 7 use a "System Reserved" "Primary" 100MB partition to hold the boot code, to be a boot partition, and provide a boot menu when more than one OS is installed. Windows does not allow the change of the drive letter when the partition you want to change is the one with the boot code and Operating System being used. So when you boot to Vista, you cannot change the Vista drive letter, and when you boot to 7, you can not change the 7 drive letter. I have found that using the 100MB "System Reserved" partition allows for giving other partitions any drive letter.

Cheers!

Thanks for the feedback. I'm not that knowledgable and should pick up a book on OS to better understand what these things. If I wanted to start from scratch, it seems that I would have to format the entire drive and then start over again. Thanks again.

You'll need to convert the HD to Basic from Dynamic, which will wipe all of the data.

You can then create New partition(s) and format using the Windows 7 installer Drive tools during Custom install.

You are most welcome, geophoto. If you can backup everything, starting over can sometimes be easier. But you do have other options if you are interested in them.

I found this link to be very helpful of partitions: Understanding Disk Partitions
