installing ubuntu 16.04 desktop on lenovo Thinkstation S30, the installer seems to mess up the boot partition and I cant get it to work - some EUFI nonsense I suspect 6 reinstalls and a bios update later, it works - now will it dual boot back to windows is another question damn what was the issue? could it just not read in the ubuntu boot? older implementation of UEFI I think I kept playing with the options, changing it to legacy etc If my linux foo was up to snuff, it could probably be resolved via a grub boot cd / repair disk and some commands
