missing operating system

Hi everyone, sorry if I'm using the forum section too much, but I managed to import a virtual machine from Vmware 7 to proxmox only that now when I start the machine from proxmox it fails to start the operating system. the virtual machine settings are:

- 2 GB RAM
- 20 GB storage
- Debian 10 64bit
- Host CPU

I left the rest of the options as default. How could I solve it?

Thanks for your help
