I just bought a new Dell laptop with Windows 8 and am attempting to install Ubuntu 14.10. I used Startup Disk Creator with the PC Intel x86 desktop image to create a bootable Ubuntu USB drive with a FAT32 format. I checked the md5sum of the .iso file and it matched the official md5sum. I booted the new PC from it and it showed these lines of output.

I manually restarted after waiting 5-10 minutes and recreated the USB drive. I rebooted with the same results (stopping at the same place).
I think the error on line seven (kernel BUG) is the root cause of the problem, but I could be wrong. Is there anyway to fix or work around this bug to successfully install Ubuntu?
I tried booting with both legacy and secure boot and both UEFI on and off. The same stick works perfectly fine on other computers.
If there is any more relevant info I might be leaving out, let me know.
