I'm using MSI GE62 6QD Laptop and recently I've just bought an Adata SSD for speeding up the booting process, so I've been following a guide online about how to set ssd to boot successfully. all is good and the system c is now using my new SSD so I thought I've succeeded, but here's the problem

every time I restarted my laptop, now windows boot manager asked me to choose which windows 10 to boot whether to boot from volume 9 (SSD) or volume 4( HDD)
i've been trying to set SSD as default in the bios but the only one showing up is Windows Boot Manager (Kingston (my old HDD)), how do I fix this?
