[SUPERBIGMAN]

how do i keep windows 7 from corrupting windows 8.1?

It won't.

I have Win7 and Win 10 on two partitions on the same laptop drive.
Previously, it was Win7 and Win 8/8.1.

Either way, you are fine. I've done it both ways.

Don't get me wrong, if i had not have the problem i wouldn't ask for advice.

Dual booting, each OS sees itself as the "C" drive. Other drives as something else.
Booting into Win 10, it sees itself as C. The Win 7 partition (or drive) would be D.
Booting into Win 7, it is the other way around.

As long as you don't screw with the Windows files in the 'other' OS, you're fine.

I have two separate drives one with win 7 and one witth win 8.1

As soon as i boot into windows 7 the os wants to do an error check on the windows 8.1 drive, if i don't stop this process it scans my
win 8.1 drive a corrupts the os.

Among all my systems that I have dual booted with 2 OS's (Windows, Linux, whatever), I have never seen that apart from an actual bad hard drive.
With a fully functioning drive, the booted OS just sees the other as 'a drive'.
