I recently fixed a virus-laden Windows laptop for a teenage niece, but I am sure she will gum it up again. Unfortunately, she isn't ready to make the plunge to Ubuntu, but I thought an accessible live version would be a great way for her to still have basic functionality when Windows will no longer function.
Could I do something like put the Live USB ISO on a separate ext4 partition and add it as a boot entry? Any help on how to do that in the most user-friendly way possible would be appreciated. The machine will be running Windows 10 with a EFI boot process.
