Boot problem in Win 8.1 and Ubuntu/Mint Dual Boot - Acer Aspire V

view story

http://askubuntu.com – I have the most peculiar issue with my system. I've got Win 8.1 installed and I've had Ubuntu Gnome 14.04 installed along side Win 8.1 in Dual Boot, and then got a boot problem, and then tried installing Linux Mint 17 in Dual Boot with my Win 8.1 system and still got boot problems. The problem is that while booting into my Linux OS the boot process hangs and I need to press Ctrl+Alt+F1 to log in via the non-graphical interface, thus needing to type 'startx' at the command prompt to start the X Server. What also seemed to be a problem was that my Wifi stopped being able to add new Wireless net (HowTos)
