CentOS

I am trying to install CentOS 8 and the installation is failing due to the following error,


The boot mode is set to Dual and there is already Ubuntu installed on the SSD's.

Any ideas what could be wrong here please?

Cheers!

do you have any non english character in user name or mount point configured during installation?

Reverting to CentOS 7 which is having it's own issues. By the way the error occurred right at the start of installation so I didn't get to select mountpoint or specify username.
