[SOLVED] Blinking Underscore Before Boot

[TrueAussie]

Hey guys, I've had my pc for a little over 6 months now and everything works smoothly and comfortably. Yet i've noticed something peculiar when booting up my windows 10 pc, Whenever i boot up my pc im displayed with a blinking underscore id say for around 5ish seconds, then my PC boots perfectly fine and smooth.
I've tried disabling fast boot along as changing my boot priority in BIOS,

My Specs

MSI MPG B550 Gaming Plus
RTX 2070 Super Windforce 3x OC
Ryzen 7 3700X 8-Core
16 GB 3600mhz Corsair Venegance Pro

My current boot device is booting off my m.2 slot along me running UEFI. Any help would be appreciated, thanks.

flashing cursor at boot could mean you have it set to look for USB device at boot, and then it goes to the M.2 drive
what is the device order, from left to right, on the Boot Device Priority Bar on the Front screen of Bios in EZ Mode?

maybe in bios, look on the settings/advanced sub menu
Under Windows OS Configuration, do you have secure boot enabled as that would stop windows booting off USB anyway
