Yes, this is the most likely reason of the failure, when you flash the BIOS it will be set the the default values. If the SATA mode changes windows will not be able to read the contents of the drive correctly to load its files and will bugcheck early in the boot process. Most of the time you will want AHCI mode but you need to use the mode that was in use when windows was installed. generally this is not a big issue, change reboot you should be up and running within the next two boots (try AHCI advanced host controler interface first)
there can be other causes: default boot drive might need to be selected, boot priority might need to be selected
all of these settings can change when you update your BIOS or restore default settings.

Check your HDD SATA mode in the BIOS. Choices should be IDE, AHCI or RAID. Whichever one it is on make note and try the other 2.Yogi

- do you have more than one drive in this system? -disconnect any extra USB devices including thumb drives and wireless usb cards (they can be discovered and the system will try to find the OS files on the wrong device)
it does have 2 drives and now
I have everything unplugged but the main hdd and the keyboard

Best solution
if you can boot onto a windows disk and see your hard drive you can repair the disk or wipe it and reinstall, just make sure your BIOS has the correct SATA mode selected before you start. (generally AHCI will be the fastest mode)
here are the repair commands i would try (mainly if i wanted to get something off the drive and not do a reinstall)
Bcdboot.exe C:\windows
BOOTREC.exe /FIXMBR
BOOTREC.exe /FIXBOOT
BOOTREC.exe /REBUILDBCD
BOOTREC.exe /SCANOS
you might need to mark the partition as active using diskpart.exe:
Diskpart.exe
LIST DISK
SELECT DISK (followed by the number of the disk )
LIST PARTITION
SELECT PARTITION (followed by your partition number)
ACTIVE
EXIT
reboot and see if you have your windows back.
