I recently bought a brand new 64 bit PC with a (ASUS) motherboard that supports UEFI and a GPT formatted 240Gb SSD, which contains Windows 7 in the first of 3 (80Gb) partitions. When the system arrived, it booted into Windows 7 like a dream, with no problems. I did not originally want Windows, but the manufacturer does not work with Linux (of any flavour), so I thought I would install Ubuntu into the second partition and dual boot. I downloaded the 12.04 64bit version and proceeded to install. Having selected to 'install', the screen became corrupted, with multicoloured garbage across the middle third of the screen !! So, I rebooted and --- MISSING OPERATING SYSTEM !!! The only way I can now get into Windows is via Super Grub2. First question - what went wrong ? 2nd - Will Ubuntu install on a GPT disk partition ? 3rd - Will it install alongside Windows 7 without screwing the boot mechanism ? 4th - How do I do it ? I have scoured the internet looking for appropriate answers and found NONE ! Please help.......
