My last day at work is tomorrow. I've had an Ubuntu 12.04 (laptop) system for several years and would like to completely remove the OS from the machine altogether. Since I'll be turning my laptop in to HR, I don't need/want to replace it with anything.
All the tutorials I've read involve a "drop-n-swap" method where you basically just install a new OS (Windows, etc.) over Ubuntu and essentially blow it out of your drive. But I don't want to do that. I want to strip the machine down to bare metal (BIOS, etc.).
Is this possible? If not, why, and what it my best next alternative? If it is possible, what are the steps?
