Installation failed after update manjaro and restart my VM

I use “Oracle VM VirtualBox” to try Manjaro KDE. During installation everything works correctly. But when Manjaro asks me to restart my VM to use the new version nothing works and the installation comes back to the beginning.

I can’t upload média in my message but when i click on restart, the terminal this freezes without error

Problem fixed, I had to delete the iso cd before restarting the VM
