Ok,

So I was updating to Windows 10 and my laptop ran out of power mid way.
This corrupted my BIOS.

I put a BIOS on a usb drive and plugged it into my laptop and pressed Win + B. This is updated my BIOS.
It stated that my screen would be blank for "several" minutes.

Now my laptop had a blank screen for about 10 minutes, is this normal? It shares the same symptoms to a corrupted BIOS.

That is strange. You have a dead paper weight for a computer right now...... right?let' hope you did not brick it with a bad bios update procedure. Let's see if we can get lucky. Remove the cmos battery from your lap top. Wait for a couple of minutes and reinsert it. All the time your lap top should be disconnected from any power source. Pray that it turns on after you apply power to the lap top. If it does, start your windows 10 upgrade from the very beginning. If that machine reboots after clearing the cmos with the battery removed, do not touch the bios again......ever.

I'm not sure why you think the bios would be corrupted by installing Windows 7

Theres no possible way this effect your bios


I'd be looking more towards the hardware failure route first

Enough time has passed. Has that bios updated yet? Just start a fresh reinstall of windows 10 when you get enough juice for that lap top. Better yet, plug it in when you are doing your updating.

Ok back again...... no joy at all it sounds like. That machine turns on and whatever lights light up do light? Do you hear your fan? You get no display at all. Man, I hope your motherboard did not get bricked. You did have a display after your windows installation failed. You had to have one even as you attempted to update the bios. Am I correct?
After your bios attempt, that is when you lost all display capabilities......right ?

Back to your original post. No way should a windows installation screw up your bios. Wrong bios install or loosing power while updating the bios will screw it up.
