The wrong drive is marked as "system"

I recently installed Windows 7. I have four partitions . Windows is installed on C:, and I also have D: , E: and G: as storage partitions . However, although C: is the boot partition it managed to mark G: as the system partition. This is causing a few problems with the Windows 7 backup feature as it automatically makes a backup of both C: and G: as System partition, and it's using up a lot of space on the backup partition.

C: Healthy (Boot, Page file, logical Drive)
D: Healthy (logical Drive)
E: Healthy (Primary Partition)
G: Healthy (system, Active, Primary Partition)

Help me

Unplug all the hard drives except the one you want windows on, re install windows.

or

Mark G inactive, mark C active, unplug all the drives except C, run startup repair until windows boots again. ( This still may not work )

Startup Repair

I wouldn`t rely on windows backup, better to backup your files yourself, I would also create a disk image when you have windows fully updated and all your programs installed.

Backup Complete Computer - Create an Image Backup

Please post an image of your Disk Management screen expanded enough to see the drives.

Here's how:
Click on the Start Orb, right click on Computer, select Manage. In the left pane, expand Storage then click on Disk Management.

I would copy the bootmgr from G to C and then inactivate G.

Bootmgr - Move to C:\ with EasyBCD

Partition - Mark as Active

Partition - Mark as Inactive

And you do not have 4 drives, you have 4 partitions, so this changes everything.

Since you recently installed windows, I would do it again. This time delete those 1st two partitions and install windows to the unallocated space or create 1 primary partition from the unallocated space and install windows there. That C partition you have windows on now is way too small.

Get the data off of D before you start.

All 4 of those partitions are almost full.

I never understand the reasoning behind that. (Four logical drives on one disk, that is.)

He doesn`t have 4 Logical, he has 2 Primary and 2 Logical.

They really should be flip flopped, E and G should be Logical and C should be Primary.

Actually, with that small of a hard drive, I would only create 2 Primary partitions on it.

OK, I still don't understand having more than ONE drive on a disk. It serves no useful purpose. It certainly is not "backup". And it certainly won't speed things up. A folder is just as good. But, I'll butt-out.

Well if you only have a single hard drive, you have to make other partitions for data storage, especially for disk images.

You mean more then 1 partition, not drive.

The entire disk is called a drive, the smaller sections are called partitions.

If you didn`t store your data on another partition, and for some reason you have to re install windows, you will loose all the data on that windows partition.
