Dear users,
I am using dell precision t5500 which came with pre installed redhat. During the coarse of time the serial key for redhat was lost, due to that it is getting difficult to install or update the softwares.
I also read online regarding problems in installing ubuntu parallel with redhat. I am thinking to remove redhat and install ubuntu, before doing it i want to make sure that whether Dell T5500 is compatible with ubuntu or not, will it work normally? otherwise is there a way to get redhat serial key again.

Thanking you.
