Ubuntu Installation Fails Due to "Inittramfs Unpacking Failed: Decoding Failed"

Problem Descripton (Solution below)

I am currently trying to install Ubuntu 20.04 (I tried different OS as well, leading to the same problem) on a fresh hard drive and I keep running in the same problem. The installation (or even the "try Ubuntu" option) fail (see picture below).

The error stack involves several lines and starts with

AMD-Vi: [Firmware Bug]: : IOPIC[0] not in IVRS table
AMD-Vi: [Firmware Bug]: : No southbridge IOAPIC found
AMD-Vi: Disabling interrupt remapping
inittramfs unpacking failed: Decoding failed
Failed to execute/init (error -2)
...

The motherboard I am using is a MSI A88X-G41. I have already tried several hard drives and verified that the OS-image I have downloaded just today is working on different machines.

I was wondering if someone already has had a similar problem during the installation of Ubuntu or any other Linux operating systems and if they have found a way to fix it. I am sorry for the poor image quality, and for not including the entire stack as plain text.

I finally solved the problem by using balenaEtcher () instead of the standard Ubuntu Startup Disk Creator. The error stack regarding the IVRS table persisted, but the inittramfs unpacking failed: Decoding failed disappeared and I was able to successfully install the operating systems.
