It's your system, do whatever you wish with it. However, Garuda does not encourage, endorse, nor support installing multiple Garuda editions at the same time. If you choose to do so, you are on your own as far as support goes. Please do not request assistance with multiple DE installs of Garuda on the forum if you wish to run this type of setup.
Experienced Linux users may be able to run multiple DE's without any issues whatsoever. Unfortunately, new users may experience many problems that they are unequiped to diagnose or resolve on their own. We therefore prefer not to encourage discussions of multiple DE installations because of the support problems it can create on the forum.
I feel this topic has run its course and further discussion serves little purpose. Nothing to see here move along now.
