Ubuntu Wily crashes on several occasions but intermittantly during boot on my Acer Aspire V15 Nitro. I have the F12 boot menu enabled. This problem also exists when booting from DVD or USB-pendrive. I had these problems from the firsts attempts to run the Live USB or installing a fresh new system.
***No such problems with 15.04.*** What happens is that the boot process ends and the system reboots itself. When not quick enough pressing F12, the system will boot into M$-Windows. Otherwise the F12 boot menu comes up. Today, at the 4th or 5th attempt, Ubuntu came up at last.
