How do you configure RAID in BIOS or UEFI settings on your PC or server?

1 Check your hardware compatibility

The first step to configure RAID is to make sure your hardware supports it. You need at least two drives of the same type and size to create a RAID array, and they should be connected to the same controller or motherboard. You also need to check if your controller or motherboard has a built-in RAID option, or if you need to install a separate RAID card or software. Some controllers or motherboards may only support certain RAID levels, so you should consult your manual or manufacturer's website for details.

2 Enter your BIOS or UEFI settings

The next step is to enter your BIOS or UEFI settings, which are usually accessed by pressing a key such as F2, F10, or Del during the boot process. Once you are in the settings menu, look for a section related to storage, SATA, or RAID. You may need to enable RAID mode or change the SATA mode from AHCI to RAID. This will allow your controller or motherboard to recognize your drives as part of a RAID array. Save your changes and exit the settings.

3 Create your RAID array

The third step is to create your RAID array, which is done through a separate menu that appears after you reboot your system. You may need to press another key such as Ctrl+I or Ctrl+R to enter the RAID configuration utility. Here, you can select the drives you want to include in the array, the RAID level you want to use, and the name and size of the array. You may also need to initialize the array, which will erase any existing data on the drives. Be sure to back up any important files before you proceed.

4 Install your operating system

The final step is to install your operating system on your RAID array, which may require some additional steps depending on the type of RAID you have chosen. For example, if you have created a RAID 0 or 1 array, you may need to load the RAID driver during the installation process, which can be done by using a USB flash drive or a CD-ROM. If you have created a RAID 5 or 10 array, you may need to use a disk management tool to format and partition the array after the installation. You can also check the status and performance of your RAID array using the RAID configuration utility or a software tool provided by your controller or motherboard manufacturer.
