I think i have an old partitioned windows on one of my other drives i havnt deleted. But since my main SSD is Number 1 in boot order the other day it got moved around causing the old partiton to be priority.

Ill have to change this around but this has also happened in the past and im not sure what would cause it?

If your drives are SATA drives then the default physical boot order is SATA0, SATA1, SATA2, ...

The logical boot order is what you assign in BIOS and may/may not match the physical boot order.

If the motherboard's CMOS is cleared intentionally or unintentionally, it is the physical boot order that automatically takes effect. If you want the SSD to always be the default boot drive then connect it to port SATA0.
