I have a hard drive that had the root, home, and swap partitions on it. I wanted to add a fourth NTFS partition so I used GParted to shrink the home partition and make the newly unallocated space an NTFS partition. Upon restarting my computer and booting from that hard drive, I got the "Reboot and Select proper Boot device" message. How do I go about fixing this? Thanks in advance for any help.
