BIOS, also known as the basic input / output system, ensures that the computer starts booting and enables the operating system to work with the hardware. In particular, it is in the BIOS that many devices are enabled and disabled - for example, hard drives.
Instructions
Step 1
When connecting a hard drive, the BIOS usually detects it on its own, no problems should arise with this. But given that the hard drives have different interfaces - the old IDE and the new SATA - you should check the settings and, if necessary, set the necessary ones. If IDE was previously exposed, the computer will see the SATA drive, but the hard drive will work much slower than it should.
Step 2
To make any changes to the BIOS settings, you must first enter the basic I / O system. Usually, when the computer starts, a prompt appears - for example, Press F2 to enter setup. If there is no such prompt, try the following keys: Del, Esc, F1, F2, F3, F10. Sometimes key combinations are used, for example: Ctrl + Alt + Esc, Ctrl + Alt + Del, Ctrl + Alt + Ins, Fn + F1.
Step 3
After entering the BIOS, you need to find the desired line to change the settings. Considering that BIOS versions are different, look on the tabs for references to SATA, IDE, AHCI. When you find them, change IDE to SATA by selecting the required value from the list. The required value can also be designated as SATA AHCI MODE or AHCI MODE. In some cases, you just need to set the IDE item to disabled (disabled), and set SATA to enabled (enabled).
Step 4
After setting the desired values, save the changes by pressing F10. In the window that appears, select Yes or type Y and press Enter. After rebooting, the disk will work in the required mode.
Step 5
Sometimes the user tries to change the SATA value to IDE in the BIOS, because when trying to install the OS, the system reports that no drives were found. The reason for this is the lack of SATA drivers on the installation disc. One of the solutions to the problem is to temporarily switch the disk to IDE mode, but it would be more correct to simply find a newer installation disk with Windows. This problem no longer occurs on disks with Windows 7 and Windows XP SP3.
Step 6
Remember that SATA drives have a different power connector than IDE drives. You may need a power adapter to connect.
