I’m on Ubuntu 21.04 on my laptop. I’m regularly using Clonezilla to clone my main internal drive to an external USB connected nvme drive. I want to test boot from this external drive to make sure the clone is working good but somewhere I read to never plug in and try to boot from an external clone drive cuz that could mess up the main internal drive.
Is there a software way to disable/disconnect the main internal drive so I can safely boot from and test the external clone drive? I know I can open my laptop and physically remove the internal drive, but it sure would be easier if I could run some command to disable/disconnect the main internal drive.
Even though I’m a newbie I can see that in order to do this I’d have to boot from something like Magic Parted on a USB stick. And then run the hypothetical (mythical?) “disconnect/disable” command from the live Magic Parted instance.
Any way to do this? Thanks.
PS: I just had a thought. Is it possible to unmount the main internal drive from within Magic Parted? Then try the external drive boot test? Then get back in to Magic Parted and re-mount the internal drive?
