It can happen your vm provider has a broken iso mount or does not support it at all. You can install your OS using netboot.xyz the following way:
1- Have your vm already installed with one of the provided templates e.g: debian 9. ssh into your vm as root install the ipxe package:
# apt-get install ipxe
Get your ip, gateway from your vm info email, provider cp or on debian this way and store it as it will be needed later.
# cat /etc/network/interfaces
# ip r
2- From your vnc or console, you should be able to see similar grub menu
after you press enter then quickly keep pressing CTRL+B ,or you can set to boot from CD only in you cp... then you should
enter your ip info you stored from the above step 1 like show in next image
