I've disabled all of the secure-boot options (secure boot, legacy boot, fastboot, & even the one in windows which I had to go to power settings & change from hibernation to shutting down).
Here's the error if it'll help:
Error mounting /dev/sda4 at /media/%Username/Windows: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sda4" "/media/%Username/Windows"' exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda4': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option.
I read online that this is a HP BIOS problem but not one of those posts actually showed how to fix the problem so I though I'd ask myself.
