Unfortunately, this is not the case. I have checked the iso, and also controlled the usb drive. Everything looks fine and indeed I can use Ubuntu live from the USB. I think that the problem is the fact that my computer has solid state disks, two disks in fact, that are available to Win as C: and D. I wanted to use the second disk for Linux, so a reformatted it, (now windows does not see it any more!), the Ubuntu installation tools sees it instead all right, it allows to create exfs4 partitions (/ and /home) , but then it stops when running grub-install /dev/sda. I does not give me the option to "install alongside othe operating systems", so I had to prepare the partitions myself. I tried also to free some space in the first drive (c:OS in win) and put there a /boot partition. Same error. I friend of mine has installed Linux on an identical computer, zapping out windows. So I assume that the problem is the strange way the disk is set up. I was able to run ubuntu live and I am annexing the snapshot of the disk organization, as seen by linux. If I can get any help I'd happy! Luca On Thu, Jun 12, 2014 at 2:20 AM, Ubuntu Foundations Team Bug Bot <
