Error when installing Ubuntu 20.04 in VirtualBox

I'm trying to set up Ubuntu 20.04 on Oracle VirtualBox 6.1.6. During the installation, I got the following error message:

The installer encountered an error copying files to the hard disk:



[Errno 5] Input/output error



This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk.  

It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed,   

to clean the CD/DVD drive lens (cleaning kits are often available from  

electronics suppliers), to check whether the hard disk is old and in   

need of replacement, or to move the system to a cooler environment.

I downloaded the file from the official Ubuntu website and multiple times, but none of the files works. I also verified the iso using echo "e5b72e9cfe20988991c9cd87bde43c0b691e3b67b01f76d23f8150615883ce11 *ubuntu-20.04-desktop-amd64.iso" | shasum -a 256 --check, but it doesn't do anything.

I had this issue as well after I had enabed hyper-v on windows 10.

To fix it I, made sure I disabled hyper-v by doing the following.

Open 'Turn Windows features on or off' (search for that in the start menu)

Untick hyper-v, Windows hypervisior platform and virtual machine platform.

Start the command prompt as an administrator. (type cmd in the start menu, right click 'command prompt' and select 'run as administrator')

Run the following command bcdedit /set hypervisorlaunchtype off

After a restart it seemed to install and work.
