Hello,
My laptop is a MSI GL62M 7RDX, and since it's a laptop, when I attempt to install KDE Neon, I need to edit the installation commands (by clicking on e button). I have to replace "quiet splash" by "nomodeset" for the installer to launch correctly.
Then everything goes well during the install until that error happen :
Input/output error, or something like that.
How could I fix that?
Thanks.

The error happens meanwhile the installer is copying the OS on the disk.
