Windows 7: System Partition on Wrong Disk

Unplugging other HD's does the trick

I also had the problem of the system and boot partitions being on separate drives (as seen in the Disk Management Console). It prevented my backup program (EaseUS ToDo 8.9) from being able to do a proper system backup. I have four hard drives. The one containing Win7 was marked as Boot, but one of the other three HDs was marked as System. I did the following:
  1. Shut down PC.
  2. Unplug the other three HDs.
  3. Reboot into Win7.
  4. Check the Disk Management Console to ensure that my main HD is now marked as Boot AND System.
  5. Shut down PC and reconnect the other three HDs.
  6. Reboot into Win7.
  7. Check the Disk Management Console to ensure that my main HD is still marked as Boot AND System.

Thanks for the help and I hope this reply helps others.

Even if you had a disk on port 1, as long as you create an install partition (on Disk 1 etc) and mark it Active, windows will put the system files there and it would be perfect. It`s when there is no Active partition that windows will create one on the 1st drive it finds available.

But, this is why we always to people to unplug all the other drives during an install.

Even when creating a dual boot, it no longer makes any sense, more harm then good.

The reason your system partition landed on Disk0 is because the installer always grabs the disk with the lowest port number for it.

You have to copy the bootmgr to C as to the instructions above. You have to run Windows7 so that this is C. Then you can delete the XP partition.

You don't "move" windows7 to the C drive. It will be the C drive when it is running.
