Windows 10: Dual booting Windows 10 and 7

I have a machine with the following specs:

i5 3570K
8GB DDR3 1600
Z77 Pro4-M
HD7950
1x1TB WD Blue (D:\ and F:\ Windows 7 x64)
1x250GB Seagate Surveillance HDD (C:\) (Windows 10 x64)

Windows 7 is installed on the 1TB drive, and Windows 10 is installed on the 250GB drive. At times (still pinpointing), I get a 'Check Disk for Errors message' in the notification area. So I did a chkdsk /f for both C:\ and D:\, and this is what I get:

I have disabled hybrid sleep and hibernation on both OS, but I sometimes get this error. Both Seatools and CrystalDiskInfo report that all drives are perfectly healthy.

Please do advise me on this issue.
