Is this normal?
I think I am booting from my m.2 ssd (because windows boots up pretty fast) but my bios says that my HDD is the boot manager.
I recently got an UNEXPECTED_KERNEL_MODE_TRAP so that's why I am asking
Perhaps it's just installed on a fast HDD? Or like Barty1884 said.
If you can get into your BIOS and go to the BOOT options and check in which order they are ( or provide a picture here ) then you can check.
If it has a list of multiple devices, it'll use the first one which is availlable, if not it'll try to use the next one, and so on...
