I have Windows 10 Pro installed on my 120GB SSD and now there is not enough space even to install win 10 update because some application automatically selects C:\ drive to installation localtion. So I decided to download Ubuntu and put it on a USB drive and "try" it so I don't need to install it. And with Ubuntu I can move all program files to a different drive and I can make a symlink to the files.
The problem is that when I try to boot Ubuntu I get a single line saying: [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later)
I found this question, but if I can't boot up Ubuntu I can't use the sudo apt-get install intel-microcode command.
So how can I boot this up?

  • Consider to download newest dot release of installer - something like Ubuntu 16.04.5 LTS or Ubuntu 18.04.1 LTS - see http://cdimage.ubuntu.com/releases/ . – N0rbert Dec 24 '18 at 21:12
  • I have **ubuntu-18.04.1-desktop-amd64** downloaded. – Noel Nemeth Dec 24 '18 at 22:19
  • I have both Windows 10 and Ubuntu 18.04 installed on a 120GB SSD and I have **Users** and **home partition** on a 1TB HDD. This works well, and after more than a year of use I still have lots of space left. This arrangement is easy to set up. – C.S.Cameron Dec 25 '18 at 03:47
  • @C.S.Cameron I want to achive the same thing, but because windows uses some files I can't move it and create a symlink. This is why I need Ubuntu. – Noel Nemeth Dec 25 '18 at 10:07
  • In such case try to upgrade the BIOS of your motherboard - as it should contain newer microcode. – N0rbert Dec 25 '18 at 10:58
  • @N0rbert Yes, it works now I can boot Ubuntu. Thanks you! – Noel Nemeth Dec 25 '18 at 19:57

    Does this answer your question? [\[Firmware Bug\]: TSC\_DEADLINE disabled due to Errata - what should I do about this?](https://askubuntu.com/questions/984970/firmware-bug-tsc-deadline-disabled-due-to-errata-what-should-i-do-about-thi) – karel Jan 28 '20 at 05:24

Go to Advanced Options and select a previous kernel (keep trying until one works if you find that some don't work). Once inside you'll have the option to bring up a root command prompt which is where you can type in sudo apt-get install intel-microcode. In my case I ran out of space during a kernel update which caused it to fail, you can fix it by running sudo apt-get update.

Just went through the same issue, almost threw motherboard to trash - but finally checked all connections inside PC and OS drive had disconnected power cable. Plugged in and all works fine.
