I am trying to install CentOs using this iso CentOS-8.2.2004-x86_64-minimal.iso on VirtualBox 6.1.
Installation fails during media check, please see the error below.

On Hyper-V the same iso file was used, and installation was OK, there was not any checksum errors, system was installed and is working fine.

What can be reason of this error ? enter image description here


Here's a thread where the issue is discussed and resolved:

Centos Installation Fails with CD Check Failed on all ISOs

TLDR: CentOS installation fails when used under VirtualBox on a host where Hyper-V is enabled. You'll have to either disable Hyper-V or install it differently.

    Good answer. I didn't even read the question correctly. !bliat! As a note to your answer, I myself have enabled hyper-v on or off at boot using bcdedit. People can find how to do that online. 1 more point for you! – Señor CMasMas Sep 24 '20 at 19:01
