incorrect "system" partion label

I set windows up over 6 months back now, for some unknown reason win 7 has labeled my very old PATA device as a system partition despite being a storage device. i have no clue why its labeled system.

is there a simple way to un label it as system? when i disconnect the device and attempt a startup repair win 7 cannot see the desired C: drive and thinks its not installed an does not allow me to repair. it throws me as there are no hidden folders on the PATA device and no "windows" folder..... Help!!

First try Bootmgr - Move to C:\ with EasyBCD..

If that comes up short, mark the Win7 partition active, power down to unplug all other drives, then run Startup Repair - Run 3 Separate Times

Win7 will never repair unless its intended boot partition is marked Active, and it often takes more than one time if another partition presently holds the System boot files.

thank you that has done the trick :) am i now right in believing if i disable that physically or through the bios windows will boot correctly? problem i had before i noticed it being labeled system was attempting to disconnecting it and not being able to boot windows after

Make sure Win7 hard drive remains set first to boot when you plug back in the other drives, after win7 partition holds the System flag which tells you it can boot itself.

Does the PATA drive then need to boot anything on it?
