I have a laptop (say,
Laptop1) with an hard drive (say
hdd1) on which Windows 8.1 is pre-installed (with UEFI, I'm told) -- and there is a dual boot with Kubuntu 15.04.
I also have another drive (
ssd1), with currently Windows 7 installed (but not pre-installed), which I previously used on another PC.
Now, I want to replace
Laptop1, wipe everything on
ssd1 and install Xubuntu 15.04.
However, I also want to be able to put
hdd1 back into
Laptop1 at any time and be able to use the pre-installed Windows 8.1 without any trouble (that is, as if nothing had happened).
How do I need to proceed when installing Xubuntu on
Thanks for your help.
