Recently I received a Windows computer as a gift. Now I am trying to install Ubuntu alongside Windows 8.1.

After using Universal USB installer to create a bootable flash drive from Ubuntu 14.04.1-desktop-amd64.iso. I attempted to try Ubuntu without installing it to make sure it worked okay.

After my computer showed the ubuntu startup screen, the kernel crashed with an error.

Computer specifics:

  • Windows 8.1
  • Intel Core i5-4210U
  • Lenovo G50-70

Here's a screenshot of the error message: error

Edit: After creating a bootable flash drive via LiLi from ubuntu-14.04.2-desktop-amd64.iso, booting was successful.

  • Disable UEFI and/or SecureBoot. On your BIOS, try to load the default values before attempting this.

  • @IsmaelMiguel I did that before attempting to boot Ubuntu.

  • @TheBestOne Try to force Puppylinux or Debian to boot. And try with UNetBoootin (unetbootin.sourceforge.net) instead of Universal USB Installer.

Given the kernel panic you've shown (the Windows one might help as well), I would have to wager that this is a memory / RAM issue.

What you should do for the time being to pinpoint the actual issue:

  1. Reboot your machine.
  2. When the boot menu shows up (shown below), select the first Memory Test.
  3. Let it run. Note any errors.

Please post back with any info from the test(s).

  • My Windows OS is working perfectly fine :) The grub on the live USB doesn't have those memory test options. I did an extensive memory test in Windows and found no problems with my computer.

  • Sorry about that. I neglected the fact that you're booting from USB. :) See this link: askubuntu.com/questions/187573/…

  • The kernel crashes before I can reach the language menu mentioned by the answer. Check disk for defects is available from grub. It merely restarts my computer.

Downloading the newest version(14.04.2) and then using LiLi to create the live USB successfully solved the problem.
