[SOLVED] HDD not showing up in boot sequence

[ChAc]

Hi there! Recently I've upgraded my pc. Most of the parts have been replaced except for my HDD which has windows installed on it. A data table in the BIOS says that the HDD is installed but I don't see it in the boot sequence and don't know how to make it show up. Help?

A disk has to be bootable, to have OS on it to show in BOOT sequence.
