    Need to change the drive designated as the System Drive


    I had Windows 7 Ultimate 64 bit installed on a partition of my 1TB drive. I recently bought a 240GB SSD and installed Windows 7 Ultimate 64 bit there. I did a completely fresh install, since I needed to move things around on the original partition anyway. So basically, I put all the drives in (which was probably my first mistake) and fired it up and low and behold, it booted immediately from my original drive, despite the fact that I had set the SSD as the first boot option in BIOS. Grr.. Anyway, I ran the setup for Win 7, hoping that would resolve the issue and I now boot (sort of) exclusively from the new SSD and into the new install of Windows.

    EXCEPT... now that I've moved everything off the original drive that I wanted to keep (onto a 3rd drive) I want to delete the old Windows partition and merge it with some other unused space on that drive... but it won't allow me to do that, since the old Windows partition is listed as the System drive, while my new Windows partition is listed as the Boot drive. I can't seem to figure out how to change this.

    The other strange issue that I came across... is that I went back into BIOS and removed the option to boot from the old drive completely... and then it wouldn't even boot at all. It kept asking me if I wanted to make a floppy disk of the SATA drivers.

    Can you plug everything back in the way it was then capture a Screen Shot of maximized Disk Mgmt drive map and listings so we can see what needs changing?

    If not, mark the Win7 partition or it's 100mb System Reserved partition Active then run Startup Repair - Run 3 Separate Times with all other hD's and peripherals unplugged. Partition - Mark as Active (
