I bought a laptop HP Envy Premium with Windows 8 on it. I wanted to install also Ubuntu 13.10 on it. I partitioned from windows the disk creating space for Linux. Then booting from a live ubuntu on a usb stick i installed on that space UBuntu. Now I at the boot only windows 8 is executed and grub does't appear. So I rebooted from live usb I installed boot-repair in order to run it. THe problem now is that boot repair gets stuck in the initial phase. In particular in the phase when it's running os-prober. Here is some info maybe useful obtained running boot-repair with '-d' : http://pastebin.ubuntu.com/6816377/ . Thanks in advance!
