I have created a startup USB with the built-in startup disk creator and I have also tried using unetbootin, both give me this error on boot-up, just a black screen with the message "Machine check error". I am using an ASUS zenbook UX31. It is working fine otherwise, and I have boot from USB without problems with other versions of Ubuntu several times before. I have seen this duplicate but the accepted answer there is a workaround, not a solution
Machine Check Exception Windows 7
- I can not boot from CD because I am using an ultrabook without any CD drive. boot usb 13.10 share|improve this question asked Oct 19 '13 at 20:14 wim 3,962185488 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted The problem is related to "secure boot" feature.

By the way, you also need to disable the "secure boot" feature, otherwise it won't work.

Communication error between CPU and motherboard.Memory error - ECC problems.CPU cache errors and so on. Program such mcelog decodes machine check events (hardware errors) on x86-64 machines running a 64-bit Linux kernel. It should be run regularly as a cron job on any x86-64 Linux system. This is useful for predicting server hardware failure before actual server crash.Install mcelogType the following machine check error command under RHEL / CentOS / Fedora Linux, 64 bit kernel: # yum install mcelog Type the following command under Debian / Ubuntu Linux, 64 bit kernel: # apt-get update && apt-get install mcelogDefault Cronjobmcelog should be run regularly as a cron job on any x86-64 Linux system.
