hello, recently i had to clean install windows 10 32 bit on my laptop (g580-20157) and while installation i found that the bios version is 62CN31WW. i realised that i have never updated the bios to next version. there are two updates which i missed, 62CN44WW for windows 7 and 62CN97WW for windows 8. the problem is, the support page on lenovo asks to downgrade to windows 7 to update bios to 62CN44WW and upgrade to windows 8 to get the 62CN97WW. as it was clean install the windows 7 got deleted from my laptop. is there any solution such that i can avoid downgrading and yet update the bios to latest version?

i had upgraded my lenovo g580 to win 8.1 and i see the bios is locked with pass... why is that?
BIOS passwords are not set in the upgrade process, they are only applied by the end user of the computer. IF a BIOS password was applied in the past, then not used or cleared it will only be resolved by replacing the system board at a service center. There are no "backdoors" or "clear cmos" options to overcome the BIOS lock issue.
