P.S. Debian is working 100% perfectly, it is up and running, the unique problem is the access to the NTFS partitions
You are running into Windows "hibernation" that leaves the disks in an "unclean" state when shut down in that manner (sadly, a default..."fastboot" as John Doe was pointing you to).
From CNET: "In the Command Prompt window, type
powercfg.exe /hibernate off
and press the Enter key. ..."
Shut the Windows system down and try again.
