Just bought a new internal hard disk and made a bootable Ubuntu USB. But while booting it says that /casper/vmlinuz not found.

  • Please help me with this – Vipul Bhadane Jul 1 '18 at 20:35
  • Did you hashcheck the downloaded ISO? How did you create the bootable USB? did you run a media check on the USB? Sounds like a bad USB setup, it boots, but can't find a kernel to run. – ubfan1 Jul 2 '18 at 1:41
  • Downloaded the iso file from ubuntu.com/download/alternative-downloads and used rufus3.1 to make bootable usb. Do you have any alternative ways to make bootable usb. I m still having problem to install – Vipul Bhadane Jul 2 '18 at 9:06
  1. Does your system meets the minimum requirements for your selected edition? Check that your ISO is for your architecture (32 vs 64 bit).
    See https://help.ubuntu.com/community/Installation/SystemRequirements Lack of enough memory can cause boot failure of the install media. Select a lower requirement edition like Lubuntu or Xubutnu if necessary.

  2. Did you md5sum check the downloaded iso? See https://help.ubuntu.com/community/HowToMD5SUM Check the number against the listing in the link for your release listed at
    http://releases.ubuntu.com under the MD5SUMS link. For other releases' hashes, like lubuntu, see:

  3. If using a CD/DVD, did you burn the disc as slowly as possible?
    See https://help.ubuntu.com/community/BurningIsoHowto If using USB install media, use a tool like unetbootin or rufus. Don't just copy files to the USB.
    See https://help.ubuntu.com/community/Installation/FromUSBStick
  4. Did you select the media check before trying to install? See https://help.ubuntu.com/community/Installation/CDIntegrityCheck
  5. Did you ever do a "memory check" (perhaps another live-media menu choice) on your PC?

Doing the above can save you a lot of time struggling with a bad install media or hardware problems.
