I have a custom Windows 10 .iso mounted. I want to boot that .iso so I can overwrite my current VPS's OS (CentOs 7).
I can't get to the boot screen because when I'm connecting via terminal, ssh will only work once the server is completely on. I don't get access to a boot screen.
Most Google results for "centos install new os" take me to tutorials on how to install Centos, which is exactly what I don't want to do.
I found this: https://www.interserver.net/tips/kb/mount-custom-iso-on-kvm-vps/
The relevant part of the tutorial just skips over the relevant part:
There you can see the system console and do the installation like how you usually would install an OS.
