I am new to Ubuntu. My laptop is currently running Windows 7 with C, D partition as virtual disks.
Now, I want to have a laptop that runs clean and fresh Ubuntu, and nothing else. All old system data, personal data, viruses, trojan should be completely removed and no partition virtual disks (Disk C, Disk D like in Windows). In an other word, my laptop should get started over again like a newly bought one.
I guess "Replace Windows 7 with Ubuntu" option may help. But I am not sure if it will help to format and reset my hard disk OR it will just delete old Windows in C drive and leave other data existed in D drive?
Please advice me. Thanks for your time.
