Formatting a system partition

So basically, I decided that I would get windows 7 and get a new hard disk to install it on, as my original is getting a little on the old side.

Installing the new hard disk was smooth, as was formatting it and installing windows 7 on it. However, I foolishly forgot to unplug (C:) which is the disk with Vista on it (which is the only other OS). This of course is the system disk, and so my Windows 7 disk (M:) is now reliant upon it to boot. This means I cannot format (C:).... I tried repairing the windows 7 installation (without (C:) plugged in) using the windows 7 disk, however it just told me what I already knew, and didn't repair it.

Is there anyway I can make (M:) a system disk, and therefore format (C:)? (Preferably without having to reinstall Windows 7)

Here's a screenshot of the partition details: http://img6.imageshack.us/img6/1364/partitions.jpg

Thanks for any replies. If any more details are needed, please ask :)

Hi. Yes, there is this way.

First, make sure you can see hidden and system files.

Then copy the bootmgr file from C: to M: (both root.)

Copy the boot folder from C: to M: (both root), telling it to skip over copying bcd and bcd.log when it asks.

Then open an elevated command prompt. Copy and paste the following then hit enter:

Code:
bcdedit /export M:\boot\bcd
Check inside M:\boot that bcd is now in there. If so, reboot to bios. Change the first boot device to the M: hard drive.

Reboot to Windows and check disk management that M: is now also the system drive.

If so, now you can format C:

Then you can also use the boot tab of msconfig to delete the Vista entry so it will not be a choice when booting the machine.

Enjoy.

Whenever one does a clean install of Windows 7, its always advisable to unplug all the drives except for the one you're installing Windows 7 to.

Also, I always go into the Computer Management section of Administrative Tools in Control Panel. I then change my hard drive letter assignments and CD/DVD drive letter also. Hard drive/partition with Windows 7 is always the "C" drive. The CD/DVD drive is always "D" drive. I find it's easier that way for me and most programs I install. Just a tip though!

I agree with veedaz, Partition Wizard is an excellent free program. I am amazed at how many features and power this free software has. Also, there's the Partition Wizard Bootable ISO image for burning to a CD for offline partitioning, etc.
