Hi, my name is Alexander, I am still in school but going to university next year, I like computers so thats why i am here, I am 17 yrs old, The first pc i've ever used was a Acer Aspire (idk which model) But it had Windows XP installed, When i used that pc i was just like 5 or 6 years old, Then i just got my very own PC on 2016, It was a HP Pavilion (Also idk which model), It had 4 gb of ram and a Intel Core I3 5th Gen.

So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...
