Lenovo Z580 won't start after BIOS update

I wanted to update the BIOS of my lenovo Z580 but when it restarted it said "start PXE on IPv4/IPv6". When i booted without LAN internet cable it gave a window with this: boot menu

Oh yeah before you say this in BIOS hdd is ranked higher than IPv4/6

I'm running Windows 7 SP1 home premium

Re: Lenovo Z580 won't start after BIOS update

hi! you probably upgraded to 5FCN95WW BIOS, didn't you? you need to switch boot mode in BIOS. I can't remember which option is enabled by default, but there are only two of them - UEFI and Legacy. you have to change to the one that isn't set by default Smiley Happy


by the way, you should know 5FCN95WW is buggy, and downgrading to 5FCN35WW would be your best bet. once you sort the boot problem out, check this guide to downgrade:
