Please help, BIOS issue!

[timbell2112]

Please help, I just installed a new update for my bios and now I keep getting a blue screen on startup, "inaccessible boot device". I have a MSI b250m Bazooka motherboard and I just installed the the latest update,7A70v15. My OS is windows 10. Please, if anyone can help me out here I'd be grateful!

P.S. I have my HDD plugged into my SATA port 2, not sure if this is relevant but I thought i should share it.

EDIT: Figured out why I was getting that weird screen, windows 7 was enabled but 8.1/10 was disabled. Changed that and I now have my usual boot screen, but still have the stop code.

List of specs:
i5 7400
b250m Bazooka
rx 480 (reference card)
1gb HDD
16gb ram 2133

Here are some picks:

It may have reset the settings. Reconfigure them

What should I change? I've been fiddling with this all afternoon an have been getting no luck. It was foolish of me not to take note of my previous setting before the update.

I have no idea I dont have the same mobo. If secureboot etc were enabled before make sure it's enabled now

Make sure the hdd is the bootdisk

I'm away from my pc rn, but as I recall secureboot was disabled. I'll check that out when I get back home. Thanks for the suggestion.

I'm back and I've tried to enable secure boot but it won't allow me. In order to enable it I have to be in a user system mode state, i'm currently in setup. I'm not sure how to change the system mode state.

It maybe AHCI. Was this enabled or disabled before?

This could be why you're getting an inaccessible boot device error now

I have SATA mode set to AHCI.
