Recently, I made a bootable USB stick with version 18.04 and install OS from the USB stick to the hard disk. The installation process follows the normal steps without any special configuration.

The whole installation process is correct and completed. Then it shows a button to request doing the system reboot. The steps of the reboot as follows:

  1. Push the button, the system is trying to reboot.
  2. The message show "Please remove the installation medium, then reboot".
  3. Remove USB stick physically.
  4. Type ENTER key and wait for a while. However, there is no response and message stops requesting for removing medium.

How about "then reboot"? Does it mean to press the ENTER key and wait for the reboot by itself, or push system reset button (send reset signal) physically?

    Close voters, while this is a very basic question it's not remotely unclear. Posting answer. – Elder Geek Jun 05 '18 at 13:10
  • Thanks for response. I have tried to remove USB stick physically after showing message. Then I type ENTER key and wait for a while, but there is no response. – john chn Jun 06 '18 at 01:39
  • I face the same question, and my solution is ... unplug my USB and wait ..., and after probably 30min the computer reboot itself. – ZenWang Aug 15 '18 at 07:04

I have the same problem. I put Ubuntu 18.04.1 LTS on USB stick as a bootable volume. Specifically, I formatted it on Mac and then ran it on a pc.

The solution I found was to press Ctrl - C after ejecting the USB stick.

It's been my experience that if you do what the system requests of you you will get far more positive results than if you don't. Please remove the installation medium means that if you have installed from a USB flash drive, unplug it and if you've install from an optical disk, eject it prior to pressing enter to reboot the system. This is the expected behavior. If this doesn't seem to apply to you add further detail to your question specifying what media you are installing from and to.

  • Thanks for response. I tried to remove USB stick physically after showing the message about remove installation medium. Then typing ENTER KEY and wait for while. But there is no response. It is about that I try to do installation from USB stick to Hard Disk. on INTEL Coffee Lake platform. – john chn Jun 06 '18 at 08:42
  • @johnchn Be aware that booting from a USB flash drive can possibly change your expected drive designations. Prior to installing, after booting from the installation media, open a terminal and check the output of sudo parted -l to make sure you are installing to the device desired. Coffee Lake is a bit too expensive for me, but you might try installing a HWE kernel prior to installation to see if you get different results. – Elder Geek Jun 09 '18 at 19:30
  • Thanks. Currently, I install OS image with version 18.04 from USB stick to hard disk. Although system can not reboot after installation, I can boot from hard disk after removing USB stick and power off . It means installation is correct and success. System booting from hard disk is functional. – john chn Jun 11 '18 at 10:05

A poweroff following by a cold start works the same as a reboot after the Ubuntu installation has been finished and you get the Please remove the installation medium, then reboot. message. Just make sure that the installation medium is removed before starting the computer again or it will boot from the Ubuntu installation medium again instead of booting normally from what is installed on the hard drive.

  1. Shut down the computer by holding down the power button.

  2. Remove the installation medium (USB or DVD). A DVD can be removed by manually ejecting the CD/DVD tray if you temporarily stop the boot process by entering the BIOS/UEFI setup utility, eject the CD/DVD tray, remove the DVD, close the CD/DVD tray, and then exit the BIOS/UEFI setup utility without saving any changes.

  3. Wait for one minute and then cold start the computer by pushing the power button.

  4. Now your new Ubuntu installation will be able to boot normally.
