Yesterday, I installed Windows 64bit over Ubuntu because I had troubles with syncronising my devices. So today i will install Ubuntu as a Dualboot, I just want to make sure, that all Ubuntu files are deleted.
I just put in the windows CD in my Laptop, booted from it and deleted all partitions and insalled Windows. I also had to download after the installation a lot of updated and I installed Microsoft Office 2010. After that, I saw that already 29 Gig of my Harddrive are in use.
Is this normal? How can I make sure that all Linux files are deleted?
Many thanks for your help
