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.

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.  It only boots every other time at startup.
  So after powering down out of a successfull session, when I go to
  start the machine again it gives a blank screen after showing the
  large Lenovo text on screen.  So I press and hold the power button
  which powers it down, press the power button, and then I get the 3
  selections of starting ubuntu or startup...
