Windows issues

Windows Keep Check Disk at startup

"fsutil dirty query d: ". This queries the drive, and more than likely it will tell you that it is dirty.

"CHKNTFS /X D:". The X tells Windows to NOT check that particular drive on the next reboot. At this time, manually reboot your computer, it should not do a Chkdsk and take you directly to Windows.

Once Windows has fully loaded, bring up another CMD prompt and type and now you want to do a Chkdsk manually by typing "Chkdsk /f /r d:".
This should take you through 5 stages of the scan and will unset that dirty bit.

Finally, type "fsutil dirty query d:" and Windows will confirm that the dirty bit is not set on that drive.
