First of all, you need to check if the BIOS can’t detect a hard disk with the OS installed on it. To do this, go to the BIOS settings (in most cases, you need to press the Del or F2 key during the initialization of the computer).

Another option is to reset the BIOS to the default settings. This can be done using the CLRTC jumper on the motherboard or simply pull out the CMOS battery for a few minutes. In some cases, it helps to replace the BIOS battery with a new one, because the old one can be discharged and not save the settings when the device is turned off.

If the BIOS doesn’t see the boot partition on the drive, you can try to restore the boot record (MBR or EFI) using a boot or installation disk with Windows.
