i have a windows 8 64 bit lenovo g 580 20157
unable to access bios or uefi
when i try to access uefi pc just restarts
have disabled quick start up in windows

thanks for any help that can be provided

also when i boot up pc and able to get menu go to bios or boot option just boots into windows

Are you holding F2 down right after power on?

Have you looked at these links?

i have done all that i have at beginning got the menu to boot into bios or choose boot device just boots into windows have used the advanced startup just boots into windows

Seems like you are not the only one having this problem:

G580 Win8 Can't access BIOS - Lenovo Community

yeah i have read that im wondering if i can get it in legacy bios mode using bcdedit /set default bootmenupolicy not sure whats suppose to go in default

Unplug the power cord (if connected) and remove the battery from the laptop for a few minutes, reinsert it, and now try to boot into your BIOS.

have tried that and even held power button down for 1 minute also removed hd since lenovo said to and tried that i dont even get a post without the hd in
thanks for your advice appreciated

I have an ASRock UEFI capable motherboard and it can be configured to "always boot to windows" and "always deny UEFI access on boot" if you have it configured for the 1 second boot option. To gain access to the UEFI BIOS, one must download and install an additional ASRock utility that can be run in Windows and you can set an option to "boot into UEFI on next restart."

So, maybe Lenovo has a similar utility and maybe it is already installed on your laptop.

wouldnt easybcd be able to do this

Did you read my previous post? Do you have such a utility? Did you check the Lenovo website for the utility? Have you tried booting to your optical drive? If you can get there, use the installation CD (repair mode) to try and access your UEFI BIOS. See screenshots in this tutorial:

Hi python53,

At this point, I really think you would be better served to post your issue at the Lenovo forum in the section for your specific model number because, as I said before, there are others having the same issue as you.
Good luck.

ok thanks im left with only one option that is to send it in i didnt want to do that but they sent me the box thanks again

Sorry you couldn't find a solution but I'm hoping all the recommendations have helped you make a decision that you are somewhat comfortable with. Good luck.
