Restoring BIOS to default (Levnovo G50-45) (v 1.07)


I downloaded the latest BIOS update (a2cn38ww.exe) from Lenovo's support site and installed it. My Windows 10 din't boot after that.

I booted Windows 10 through Legacy Boot in BIOS and Windows 10 was working fine after that. Now I'm not  able to boot Windows 10 through UEFI.

If someone can provide me with the v 1.07 download link, I will install it and we can call it a happy day for everyone.


I've got an AMD A8-6410 APU with Radeon R5 graphics, 8 GB of memory and 1 TB HDD and running Windows 10 Pro.

Please help.

Have you set defaults on the new BIOS, then saved and exited?

Sometimes this will restore boot function after an upgrade happens. Also - try looking at the boot options for "secure boot" to see if enabled. Try turning that feature to disabled and restart.

Good luck.
