Can't install Linux without BIOS password (feddit.uk)

Hi, I was hoping someone may be able to advise me. I have an old Acer laptop that's a bit delapidated but I thought this would be an ideal chance to try out Linux as the laptop is basically of little value anyway so if I mess something up, nothing will be lost.

I've backed up everything I want to keep and I've written the Linux Mint image to a USB stick. I can get into the BIOS screen by pressing F2 but I'll be dammed if I know what my password is. I'm not sure if I ever did.

I read that updating the BIOS driver should allow me to remove the BIOS password but after a somewhat risky decision to run a driver I found on the internet (Acer refuses to recognise my old laptop so won't provide me any driver files), the BIOS still requires a password to open. Is there anything I can do with this old laptop? Is there any way to remove the BIOS password?

Edit: should have pointed out that the laptop uses UEFI rather than BIOS.

The method to reset the BIOS password varies heavily by model. It's an Acer, so by definition it's consumer-grade, and doesn't have the higher security options of enterprise gear. Being so old (2012 or so, based on another comment, meaning ca. 3rd Gen Intel Core) works in your favor as well.

Start by googling for the model and "reset BIOS password". You might also look for similar/related models that would have the same method. Make sure you exhaust this thoroughly, because the next steps are rougher.

Next up, find forums like BIOS Mods and Bad Caps that specialize in BIOS needs. You may need to pay for a subscription, and it may get very intricate. And it may not even help.

Finally, you can find professional repair shops like Black Horse Repair. This will involve real money, probably more than it's worth. Make sure they have a plan before you send it in.
