Windows 7: Disk management

Disk management

This is my first post ... so please be gentle with me!!

System is dual boot to Vista home premium and Windows 7 pro.

Vista is on E: and Windows 7 is on C:, and both work fine.

Problem is that I want to use N: for backup (this previously had Vista installed on it) but can't because it is a system disk.

Question is, how do I make C: the system disk so that I can use N: for backup?

Any help would be appreciated.

Why would you not include the Disk Mgmt drive map so we can see where these partitions actually are? Please maximize the window and include everything so we can answer you best.

Sorry, is this more use?

Below this, disks 4, 5, 6, 7 are card readers, 8 is M: an external Simple drive and 2 CD Roms.

Apparently your Backup (N) drive was marked Active so that when you installed the OS Dual Boot files were placed on the first Active partition. This can be avoided by placing your OS HD's in the first ports or scrupulously assuring that no prior data drive is ever marked Active.

To repair this, mark the Win7 HD (C) Active: Partition - Mark as Active (Method Two) then mark Backup (N) Inactive: Partition - Mark as Inactive - Windows 7 Forums

Now unplug all other HD's, plug Win7 HD into Disk0 port, make sure it is set first HD to boot in BIOS setup, boot into Win7 DVD or System Repair Disk to run Startup Repair - Run 3 Separate Times until it starts on its own and holds the System Active Boot flags.

Now there are two ways to proceed. If you want Vista HD to be able to boot independently via the BIOS then do the exact same steps as above for Vista while it is plugged in alone. Then plug back in Win7 HD, set preferred HD as first to boot in BIOS setup, boot other HD using one-time BIOS Boot Menu key at boot.

Or you can plug back in Vista HD, install EasyBCD to Win7, add Vista to a Windows Boot Menu on the Add OS Entry tab. Vista will then be dependent upon the Win7 HD. EasyBCD (free Download at bottom of page - no name or email required)

Thanks Gregrocker, everything worked a treat, including EasyBCD in the final part of your solution. Thanks again.
