My laptop is a Lenovo T-510 running i7 @ 2.2GHz (I think; maybe 2.4GHz), 8gb ram, no discrete graphics card, and a 500gb hdd, and came preinstalled with Win7, Pro I think. It's been a great little laptop but I've been trying to install Ubuntu alongside Win7. I shrank the Windows partition and have 120gb of unallocated space to use for Ubuntu 14.04. I downloaded the 64-bit Ubuntu 14.04 and tried running it from a flash drive and from a dvd and haven't been able to boot from either. They appear in the boot menu but when I try to boot from the usb it says it's an invalid disk and the dvd doesn't seem to do anything at all and Windows resumes normal startup as if it weren't even there.
Anyone got any ideas?
EDIT: Not sure if this makes much/any difference but my laptop runs BIOS, not UEFI.
