Installed Ubuntu 13 to new computer. No error msgs during install, everything seemed to work fine. At the end of the install, did the system restart and the computer booted but just hung up on a blank orange screen after the system checks. Powered off and tried again multiple times with the same result. If the install disk is in the dvd drive the computer will load the OS from the disc when booting. No disk and you just get the orange screen. This is a new gaming PC with lots of memory running an Intel processor. Any help would be appreciated. Thanks

Now it boots to Grub 2.0 menu. When I select ubuntu it tries to load it but just hangs at "loading initial ramdisk"
