hello When I use the dd command to boot other operating systems in an original Ubuntu and. I use it unmodified. The command works and it boots. Some hostings changed the dd command, and when I use this command and reboot, I get the System halted error. How do I solve this problem? How to bring Ubuntu back to a state where the dd command works? I have checked all the cases, the execution of this command is blocked by Systec admin hosting and the main files of Linux. Please guide me.

like this

dd if=/path/to/example.img of=/dev/sda bs=1M

I can't think of anything, I need help
