when you said "reset". did you mean back to factory settings?
if it was a forced reset/shutdown, you may have most likely interrupted a windows update/installation. this causes the system boot record to get corrupted.
if your laptop has a builtin recovery uefi, try pressing F8 during boot and select "recovery os" or something like that.
if it doesnt have one, then you will need to get a windows installer. you can go to the site here.

the usb/dvd will be your recovery software to try to fix this.
let me know if you are able to go to the windows recovery screen and ill guide you on the next steps.
as for the BIOS. i am not sure what you are saying tho. it sounds like your monitors resolution is smaller than your BIOS screen... your graphic setting in your laptop mustve gone bad for some reason as well.
