Installing 20.04 beside Windows?

[Karl Auer]

I have a new laptop, with Win10 installed on it. I would like to
install Ubuntu 20.04 while keeping Windows bootable.

When I installed 15.10 I seem to recall that Ubuntu had an option to
resize the Windows partition and install Ubuntu in the remaining space.
20.04 doesn't seem to offer that. It recognises that Windows Boot
Manager is installed though.

Is there a way to resize the Windows partition down to (say) 60 GB and
install Ubuntu? If it's not easy to do, then I will just overwrite
Windows, I think.

Regards, K.
