I recently bought a new IBM Lenovo, with pre installed Win 7. First thing I did was to take a backup of it, using the pre installed one-click recovery system. After that I installed Ubuntu Netbook. During the installation process, I was asked to partition the harddrive. It was a slider option, so I slided until the Win partition was about 100GB, because I'm not a big MS fan. Now there is a boot menu, making me choose to boot win or ubuntu.if i wanna have windows n linux on d same pc, should i repartition my hd?
