HI! I decided to disconnect one of my hard drives (I have 2) and forgot which one is with OS and disconnected the wrong one. After connected back, but what I can see is only black screen and "restart ctrl+alt+del". In BIOS computer can see only one hard drive, the one that I didn't touch, but if press F8 while starting system it has both. Please advise how to add one more hard drive to BIOS or should I do something else?
How to add hard drive to BIOS after disconnecting
Please remember, whenever you disconnect a hard drive from your CPU in case you have more than 1 hard drive, make sure your CPU is turned off. If you accidentally disconnect it while it is running, it can corrupt your data and worse physically damage your hard drive. When your CPU is running, your hard drive or the plates inside your hard drive are spinning so fast that a slight interruption can damage either of the plates physically.
Since you already reconnected the hard drive back to your CPU, I guess the only problem now is to manually detect both hard drives from the BIOS. I don’t know if F8 has a different use for your BIOS but I know F8 is used to display the interactive menu in Microsoft Windows.
If you reconnect the hard drive, make sure you return it to its original location and original cable. Also make sure you didn’t change any of the jumper settings of the hard drive because it will affect the accessibility and functionality of the drive. To fix your problem, go to the BIOS by pressing DEL, F2, or F12 depending on your system.
Go to the drive section then detect your hard drives manually since automatic detection fails to work. Once both drives are detected, save it then restart your computer. Normally, when you remove a hard drive and then you reconnect it back, supposedly your CPU will automatically detect it and then save the new settings. But in your case, I think it didn’t happen that’s why you need to manually detect them.
