Hi,
I have two hard drives one is used with my operating system and the other for storage C: and F: drives, respectively. Everything worked fine for the longest time until recently. Now whenever I boot up I get the following error: Reboot and Select proper Boot Device or insert...
In the BIOS boot up section instead of seeing Windows I see Hard Drive with no option to change to Windows.
I found that if I remove the SATA and power cables from the back of F: hard drive everything reverts back to normal and I am able to start my computer as normal. However, once reattached I get the above error.
Why am I having this problem, suddenly?
