Installing ubuntu is always done by installing ubuntu first on some (USB/CD/something_else). And then booting from that thing. And then installing ubuntu on your pc from there. But if it's possible to install on a USB and also load it from there, then why cant I just install it on the partition directly.
Is it possible to just create a partition, then install ubuntu onto that partition from the OS that I'm currently using. And finally just modify UEFI/GRUB so that you can boot it.
And if so, are there any tools for this?
