How to turn on the disk in the BIOS?

If a new disk is not detected on your computer or the old one is no longer detected, there are several ways to enable the hard disk in BIOS or turn on the disk controller. Today we will tell how to do it.

How to enable disk in BIOS

First you need to enter the Bios. To do this, you need to press a certain key while the computer is loading, in most cases it is the "del" button, but it can be another key or a combination of both.

Immediately after turning on the computer, the message "Press DEL to enter SETUP" or similar is usually displayed at the bottom of the screen, at that moment you need to press the required key.

In the window that opens, you need to find the "MAIN" or "Standart CMOS Features" tab, where the list of connected optical and hard drives is displayed and make sure that the disc is not detected. That is, it is not in the list of connected devices, or if it is the only disk, it says "none" in all paragraphs.

  • If the disk is Sata, you can check whether the sata interface controller is enabled. In the "SATA configuration" tab in the controller row, the item "enable" should be selected, if not, you need to select it.After that, go to the previous tab, and if the device is still not there, select the required sata connector and select auto, after which the device should be determined.
  • In the event that the disk was disconnected before someone intervened in the BIOS setup, i.e. it was disabled (how to do this, read here: How to unmount a hard disk), you can return the BIOS default settings by selecting "Load Defaults BIOS", or similar depending on the BIOS version, for example: "Load Safe-Fail Defaults" and t .P.
  • If this is a new disk and it is detected in the BIOS, but not detected in the operating system, it may not be marked up or has a file system that is not supported by your OS, then you need to format it. How to do this, read in this article - How to format a hard disk through the BIOS, be careful, formatting will destroy all data on the hard disk.

If the above does not help you, especially if you have old hardware and you have several hard drives connected, the problem is most likely not in the BIOS. Try this:

  1. Turn off the computer and check the position of the jumper on the hard drive, if it is the second hard drive, it should be in the "slave" position, if the first is the "master". Information about the position of the jumpers is usually located on the lid of the device.
  2. If you have an old ide disk and are not detected, even in the "slave" position, you can try to remove the jumper.

All actions must be performed when the computer is turned off, de-energized. After each change, of course, it is necessary to go into the BIOS and check the availability of the device.
