And I can't guarantee you anything. Maybe a good story.
OK, I've updated so many BIOS's that I've lost count and yet to lost a board or machine or OS over this. But I've done so many and well, know some ropes and never got hung up.
Fine, but what do I run into? Settings. Yes you told me you can't get to the BIOS. To get there I get out my W10 USB boot/install/repair stick and boot from that. It varies with the PC which F key to press to get it to boot from USB so you should know your PC for that. In a few extreme cases I unplug the HDD to force the machine to use the USB.
In Windows 10's boot/install/repair stick is the repair option and the access to the BIOS. So let's cover how I make that stick. Read Steps 1 to 3 at https://mspoweruser.com/clean-install-windows-10-using-media-creation-tool/ DO NOT GO FURTHER.

OK, we're finally in the BIOS settings. But what we do there depends on why it BSODs. From my many encounters it's usually the SATA settings. Sometimes the owner installed the OS in some IDE compatibility mode and if that changes with a BIOS update we only need to set it back and the machine will boot again.
If there is RAID setup involved there is no quick answer there. You have to remember what you set it to and try that again. I'm not a fan of RAID for users that are not into their PCs.
So that should get you into the BIOS and one of the common fixes I know of.
So I'm a bit f***** right now it seems.
I'm sitting with a Lenovo Y520-15IKBN. Last night I received a message from the Lenovo Utility program that there was a BIOS update ready. Thinking it was to close the recent security holes, I decided to update.
The installer gave a warning that my computer should be fully charged(check), connected to power (check) and with a BIOS set to defeault settings(check).
After the installer finished, it restarted my PC, the Lenovo logo came up as usual, but quickly gave me a blue screen of death, with the message that it couldn't find any bootable devices. It then restarted, booted up on the Lenovo logo, and I left it there overnight to see if it just needed some time (no luck with that).
So now I'm stuck with a PC without a working BIOS I think. I can't enter the BIOS with F2 or DEL, however I can enter the Boot Menu (which shows none of my discs). I tried booting from a USB-stick with windows on it, and funnily enough, my secondary HDD came up. I tried installing on this, but when I booted again, it failed me.
I've tried a few of the standart Windows start-repairs, but none of them works.
Is there a way to install BIOS from a USB-stick, or save it some other way?
I would rather not have to wait until monday to contact Lenovo, then having to send in my PC and wait 3 weeks for them to fix it.
Please respond with any ideas, or if I need to clarify something.
