Kernel panic during Ubuntu installation

I am aware that there is a number of similar topics, but I can not find an answer to my problem.
I had removed Ubuntu 16.10 from my machine – removed Linux partitions in Windows (dual boot), run below command in Ubuntu:

sudo lilo -M /dev/sda

Now I would like to install Ubuntu 18.04.4 LTS. I have followed this tutorial to create bootable Ubuntu USB stick. When I choose Try Ubuntu without installing or Install Ubuntu I receive a trace which part I am posting below:

[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version 0x25 (or later)
Initramfs unpacking failed: LZMA data is corrupt
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.3.0-28-generic #30~18.04.1-Ubuntu

My machine meets the system requirements. I have burned (followed tutorial mentioned above) USB stick twice, it did not help. I have checked file Md5sum – it is correct. Could you help me with that problem?

EDIT:

According to suggestions made by users karel and K7AAY I have updated BIOS on my machine and have not run below command in Ubuntu (I don’t have access to Ubuntu as I had mentioned above):

sudo apt-get install intel-microcode

The only result of updating BIOS is that below line is not appearing anymore, but the main problem – unability to install Ubuntu 18.04.4 LTS still exists.

[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version 0x25 (or later)    

SECOND EDIT:

I have prepared Windows 10 (since on my machine Windows 10 is installed) USB stick. I have booted on that media and selected “Repair your computer” -> “Troubleshoot” -> “Command Prompt”. I have run below command and restarted the computer.

bootrec.exe /fixmbr

Then I have tried one more time to install Ubuntu via Ubuntu USB stick. It has not helped, the problem still appears.
