My laptop has a corrupted bios indicated with the flasing light sequence, it has no hard drive installed now, can I download a copy of bios from HP website to a usb flash drive , which version do I need as I am unable to enter laptop
I suggest you research this on the HP support forum. Recovering from a bad BIOS is tricky (if it's even possible to do yourself). As far as the version, I would use the latest version for your particular HP model.
