Windows 7: Changing system drive

Changing system drive

Hi,

I have just installed Windows 7 on drive e: on my laptop. I already had Windows Vista on drive c: and actually wanted to install Windows 7 on that drive but couldn't free up enough space. Now I have Windows 7 on drive e: I'd like to get rid of Windows Vista and free up the space on the c: drive.

I have used vistabootpro to delete the Vista OS but all the files are still there. I read elsewhere that I can just format drive c: however when I've gone to do this I get an error message saying I can't format because this is my system drive.

My question is how can I switch the system drive to drive e: so I can safely format drive c:?

At the moment the attached .jpg shows what I see under each drive letter in disk management.

Hello Nialljcr, welcome to Seven Forums!



In Windows 7 disk management mark the Windows 7 partition as Active, then do the 3 startup repairs with the separate restarts to create a new set of system boot files to the Windows 7 partition, see Option One steps 1 - 3 in the tutorial at the link below for an outline on the entire process and be sure to post back with any further questions you may have and to keep us informed.

That will make it possible to then remove the Vista partition.

Did you boot the Win7 installer to install to C? If so it would show up as C when you are booted into it; if not you installed from Vista which had already reserved the letter for itself.

After reccovering the System Active boot files back into Win7 partition, if you want to recover the space from deleting Vista then post back a screenshot of your full Disk Management drive map and we will give you the steps using free Partition Wizard bootable CD.
