I am currently running Ubuntu 16.04 LTS on a Dell Tower PC which was originally loaded with Windows Vista Operating System. I have tried several times to upgrade to Ubuntu 18.04 from the current 16.04. Download was successful: however, the system would not start up.
Next burned a startup disc from Ubuntu website and tried to boot with that – download and burn were successful, but again system would not start up.
My guess is that I need to update the original Dell Vista BIOS (A01) to current (0360-A07), but do not know how to do this from Ubuntu OS.
Any help with this , or other advise would be much appreciated.
THANKS
