Hi guys. I flashed the MS-1761 unlocked BIOS and now instead of booting to Windows 10 I'm getting the message "Reboot and select proper boot device or insert boot media in selected boot device and press a key". I changed RAID to AHCI, removed every single USB device and of course changed the boot order. I even tried Startup Repair from a Win 10 recovery USB, but it couldn't find the problem. The only way I can start Windows is pressing F11 and selecting my SSD every time I start my computer.
Is there anything else I should try, apart from reinstalling Windows?
[EDIT] After hours of trying every solution under the sun (including, bootrec, diskpart, EasyBCD, and Easy Recovery Essentials), I solved it. This is how I did it:
1- Unplugged everything and removed the battery.
2- Removed the cable that goes to the CMOS battery just in case, waited a few seconds and then plugged it in again.
3- Removed both the Windows SSD and the data HDD.
4- Plugged in my laptop and turned it on.
5- Shut it down after 10 seconds.
6- Installed the SSD and HDD again, powered on my laptop, checked the boot order in the BIOS screen. IT WORKED.
That was it. Maybe I should have tried step #2 before I started looking for other solutions, but I don't know if that was the thing that solved it. I feel so dumb now XD.
