How to change boot order if Windows 8 is installed as a second OS


If you have, let’s say Windows 7 as your primary OS and you install Windows 8 as a second OS, then MBR will get updated and first boot priority will be given to the last installed OS – in this case to Windows 8.
MBR which stands for “Master Boot RecordOpens in a new tab.” is kind of boot sector located on the first sector of the hard drive and contains information that during the boot process tells to the computer which partition to use for booting.

If you want, you may change this order by your preference.

Scenario 1: Change order for Windows 7 to boot first, using the Windows 8 pre-boot menu

During the booting process, as soon as you see this screen:
