Can you tell me exact things that I have to change

If your drive is just partitioned in MBR, it should work out-of-the-box. If you plan on using the MBR for booting(Non-EFI boot), you need to adjust those settings in your BIOS. Usually under bppt, called boot mode or something. Change this to legacy. If it's disabled, try searching for fast boot(Or similar) and disable it. Then you should be able to boot using MBR.

In BIOS there should be a setting for the boot mode you want to use. I you have a UEFI BIOS then you need to have that setting on AHCI as that allows you to boot the GPT partition that is required for UEFI BIOS. MBR is used for EFI BIOS so if you don't have one don't used the MBR or Legacy option.

MBR is not used for UEFI BIOS's you need to have the sata controller in the BIOS set to AHCI if you have a UEFI BIOS is you have EFI you need to put it to Legacy or IDE in order to use MBR.
