I've decided to install Ubuntu alongside Windows 10 and I'm trying to follow these instructions.

After I'm done with the installation process, a window pops up that says I need to restart Ubuntu. I click on "restart now" (or something like this) and get a screen with the following:

[ 0.000000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version 0xb2 (or later)

[ 1579.737040] reboot: Restarting system

And that's it. Nothing happens.

Sorry if this issue is easy to solve, I'm an inexperienced user and googling didn't get me anywhere.

Edit: the first error does not seem to be the problem, because it's not a fatal error which would prevent Ubuntu from booting

You should manually restart your system (using the hardware button or power cycle).

The first message, that TSC_DEADLINE is disabled, is a problem but not a fatal one. It is not interfering with boot, reboot, or shutdown. TSC is a "nice to have," not a "must have". See the good discussion of this error on the unix StackExchange.

Note that the instructions you followed assume some things about your computer (in particular, that it is a newish machine with a UEFI BIOS). That's probably totally right for you, but if not you may have some trouble booting. Good luck!

  • Also, [1579.737040] is a timestamp - the system had booted 1579 seconds before this line was printed. That's about 26 minutes...the time needed to install. Software reboot had apparently failed (we don't know why), time for a hardware reboot. – user535733 Aug 26 '18 at 13:41

start your system in non graphical mode or in recovery mode and install the microcode

For Intel 

sudo apt-get install intel-microcode #(to install )
sudo apt-get upgrade intel-microcode #(to upgrade )

For AMD 

sudo apt-get install amd64-microcode #( to install )
sudo apt-get upgrade amd64-microcode #( to upgrade )

If this not help update your BIOS

Check your system by running command iucode-tool --scan-system , sudo dmidecode -t bios -q and cat /proc/cpuinfo | grep 'microcode' and post the result
