Is sometimes a hardware support issue. I don't see much about this PC but when this happens to me I usually go with another distro. Nod to Linux Mint.
I'm running Windows 7 Ultimate 64 bit edition on a 3TB GPT hard drive with the standard three partitions that Windows creates. I have an ASRock Z97 Extreme6 motherboard with an Intel i7 4790k processor and 8GB of RAM.
I've been trying to install 64 bit Ubuntu alongside Windows for several days now and keep running into the same error. I create a bootable USB for the installation ISO and boot from it on startup. I am given the option to boot through BIOS or UEFI (two different options for the USB when I pull up the boot menu), but the outcome is not different for each, just the interface. When faced with the menu to choose whether to try or install Ubuntu, selecting either option brings me to a black screen. I've let the screen sit like this for a couple hours and nothing changes. On a USB with an activity LED on it, the LED does not flash during this time.
I have tried deleting the installation ISO and redownloading it, to make sure the file downloaded correctly. I have tried rewriting it to the USB, trying a different USB (including one that I just recently successfully used to install Windows), and then trying a different USB writer on each USB drive (tried Rufus, Pen Drive Linux's USB installer, and ImageUSB). None of this has changed anything. I have no idea what the problem could be, as on the same hardware I have previously been able to start the installation of Ubuntu (I quit halfway through). The only difference between then and now is that I've installed a better CPU cooler and an additional case fan.
