I have spent significant time trying to upgrade the BIOS. I'm almost ready to re-install windows 7 or greater as I am unable to run the .exe through any means (tried wine but I'm not that proficient with it, and I'm concerned doing a BIOS update through Wne is risky). I also tried to use freedos, was able to boot from USB and navigate to the USB drive and look at the directory to find the .exe files, but non of them will run.
So I'm stuck here trying to understand how to upate my BIOS with a linux machine when Lenovo only seems to provide solutions for windows operating systems to update the BIOS on the B50-45. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1496637 Title: Ubuntu 14.04 only successfully boots every other time at startup Status in linux package in Ubuntu: Incomplete Bug description: I have a Lenovo B50-45.
