Aspire 9520g - suspect corrupt BIOS + no password for win Vista
I have been given an Acer Aspire 9520G, that looks to have been messed about to a degree where I am on the verge of putting it on Freecycle for somebody with more time and brains than myself to try to fix. It is loaded with with Vista Home Premium and XP - the F2 key does not work to access BIOS and it only progresses through boot sequence if I tap the space bar! It boots to the win Vista sign in screen, and asks for password - which of course I do not have!
By pressing F8 during boot, I can access "Advanced Boot Options" but I cannot see anything there which is likely to help me. did "Repair your computer" once - nothing changed.
I have tested the HDD in a caddy on my main PC - seems fine - The plan was to do a clean install of Win 10 (I have bought an install disk & product key) but I cannot get it to boot from CD unless I can change BIOS settings!
I have also bought a 16GB Sandisk USB memory stick, with a view to making a bootable stick that will do something good - but as this is something I have not tried before, I'd prefer to be flamed for my ignorance and look to you good people for advice - if I am snookered, please say so, and I'll not waste any more of your valuable time!
