When I upgraded to Windows 7, I bought a new mobo, graphics card, etc... I installed Windows 7 on a new 128GB SSD drive (C: ), and then pulled my old 1TB drive with Windows XP on it from my old machine and installed it as D:.
When I try to go to "Backup and Restore", and click "Create a system image", Backup and Restore misidentifies my old 1TB drive as a System disk, so I can't create a backup on it, and Windows demands that it be part of the backup, even though it's mostly just documents on this drive (there are some programs installed on this drive - Steam and Microsoft Flight - is having software installed to this drive enough to make Windows think it's a system drive?)
I've already marked the D: drive as "inactive", deleted D:\Windows and all the cruft associated with it (pagefile.sys, etc...). Disk Management shows C: as "Boot, Page File, Crash Dump, Primary Partition", and shows the "System Reserved" partition on the same drive (the D: drive wasn't plugged in when I installed Windows 7.) Disk Management shows D: as "Primary Partition", and that's it.
diskpart "details disk" shows this for D:
DISKPART> detail disk

No "Boot" or "System" in the Info column.
So... What's left? What do I have to do to make this not be a "system" drive in Backup and Restore's eyes?
