I looked at the Lenovo support site and saw no evidence of a bootable BIOS update CD for the G405 and G505. For the Lenovo systems I've seen before those images are available alongside the Windows executable (.exe) updater that you've downloaded. The .exe will not work from within Linux, and you don't want to try using it from within WINE. You should ask Lenovo if they can supply the bootable BIOS update CD. Here's a quote from the Lenovo site regarding the BIOS Update CDs available for Thinkpad laptops: The BIOS Update CD can boot the computer disregarding the operating systems and update the UEFI BIOS (including system program and Embedded Controller program) stored in the ThinkPad computer to fix problems, add new functions, or expand functions as noted below. I think that's the type of BIOS / UEFI updater you want. You can use such an image by burning it to CD and booting from the CD, or you can use information from one of the many locations online like https://workaround.org/article/updating-the-bios-on-lenovo-laptops-from-linux-using-a-usb-flash-stick/ to create and use a bootable usb flash drive as the basis for updating the system. I'm concerned that Lenovo doesn't seem to make the update CD image for the G405/G505. Do they only provide them for Thinkpads? If so, not cool. Hope you find a solution. JP
