Windows 7: System Partition created on the wrong Disk

09 Oct 2013   #1

Windows 7 - 64 Bit
System Partition created on the wrong Disk

First of all, I would like to say, Windows Installer needs A LOT of work. Too buggy.

My problem:
I have DIsk 0 (500 GB), and DIsk 1 (250 GB). These are seperate HD, not partitions.

I have installed Windows 7 on Disk 0.
However, the dumbass windows created the System partition on Disk 1.
Please refer to the screenshot below.

This is a big problem because if I remove Disk 1, Windows will not boot up anymore.

How can I fix this?

P.S. I have been troubleshooting this windows installer thing for the last 8 hours. Finally was able to install it. Ran through a lot of stupid mistakes this Windows Installer should have been able to figure out. Which is why I'm so mad. So excuse me, if I offended anyone.

Have a read of this tutorial
Bootmgr - Move to C:\ with EasyBCD

Or you can try unplugging disk 1 and running startup repair three times to rebuild boot files on disk 0, if successful plug disk 1 back in and mark as inactive
Startup Repair - Run 3 Separate Times
Partition - Mark as Inactive

That was great! I've used EasyBCD. The process said it was successfull. Now I got to find a way to delete that system partition from Disk 1. Would you know how?

Windows 7 64 bit Ultimate


It seems that I'm having the same error, and the solution might be applicable to my case as well. I was just wondering about the warning "When you move the bootmgr from the 100MB System Partition to the C:\ partition, you loose the Windows Recovery Environment. "

Is this only for the first startup after the change or is it permanently? what is the "Windows Recovery Environment"?

I've solved all my problems.

1. As Pauly suggested, use EasyBCD to move your system partition to C:\

2. To delete the system partition from another drive, I've used Live Linux USB to boot into Linux and remove the partition from there.

Reboot to tap the F8 key to see if Repair My Computer is now on the Advanced Boot Options. If not confirm C is marked Active, unplug any other HD's to run Startup Repair - Run up to 3 Separate Times

Unless it's been upgraded yet as promised by its creator, EasyBCD doesn't complete the job because it does not rewrite the Repair My Computer link to F8 Advanced Boot Options, which is why it's best to first Mark C Partition Active (which must be done anyway) to run Startup Repair - Run up to 3 Separate Times after unplugging the other HD.

Once Win7 boots, you can plug back in the other HD making sure Win7 remains set first HD to boot in BIOS, mark SysReserved partition Inactive as already suggested, then delete it, extend the partition to its left into the space: Partition or Volume - Extend
