How many thousands of boot repairs do we need to do before badged members who help in these threads pick up the basic steps?
When the System flag - which signifies where the boot files have been placed - is on a data partition it has been incorrectly derailed there during install or repairs, likely because it was the first partition marked Active. The installer or Startup Repair will (re)write the System boot files to the first Active partition.
To correct this, mark the Win7 partition (or it's System Reserved partition if it is present) Active in Disk Mgmt or using Diskpart: Partition - Mark as Active
Then to write the System boot files to the Active partition run Startup Repair - Run 3 Separate Times until Win7 starts and holds the System Active flags.
If it will not mark Active it is likely a Logical partition which needs conversion to Primary first using Partition Wizard CD. PW also has a cool new feature on Disk tab to Rebuild MBR which may preclude the need to run Repairs x3.
If it will not repair it may have corruption requiring leaving it the way it is (wrong) or reinstall.
Spot on
We know that it's correct because System Active flags are together on the System Reserved partition which is meant to boot Win7, thereby confirming that's where the boot files reside.
The actual Boot label is on C to show us which OS is booted now.
Had the System flag been derailed to another partition, by marking SysReserved Active and running 3 Startup Repairs it should rewrite the System boot files there.
If you wanted to cut out the SysReserved partition, you could mark C Active and run the 3 Repairs and C would take the System Active flags and boot itself. But I wouldn't.

guilty of charge gregrocker,
Personally I know mine is wrong,
I will take care of it when it's time to install Windows 8.
No prob. What's important is that these fundamentals are remembered to help others.
I have to disagree that running system repair x3 is the only or best solution to a boot problem. I have had occasion where it got it's knickers in a knot and eventually (after a long time) came back with a "cannot repair this computer". If you know you want to fix boot files then I recommend the "bootrec" sequence first and when it works as it generally does, it's a very quick process.
