Fresh install with virtualbox topic

Hello,
I would like to install Ubuntu on my Samsung Series 5 Ultrabook NP530U3C, but still want to possibility to use Windows 8.
As the SSD is only 95 GB, then I was thinking that the disk is to small for dual boot. So I heard something about virtual box could be a possibility.
Could it be a solution to my problem? What do I need to do before I erase my hard drive to install Ubuntu?

I know there is a program called "Wine", but it never worked for my Windows programs. That is why I looking for new solutions.

VirtualBox very slow compared to Vmware topic

Hi,

I have Xubuntu 14.04 32bit host, where I have installed latest VirtualBox with latest extensions. In it I have Win 7 64bit guest, with 3GB RAM, 2 processors. Everything works great, but HDD operations are VERY slow. When i run HDtune test in guest, hdd speed is approximately 30Mb/s. (booth host and guest are on same SSD on separated partitions) So I made a little test. I have copied hdd content to .vdmk file and run it in VirtualBox. Hdd speed was still around 30Mb/s. Then I have installed Vmware player and created new virtual machine, but then added the same virtual HDD. When I run it in Vmware (similar setup as VirtualBox) and do HDtune test, average HDD speed is around 250MB/s !!! and whole system is much faster.

So how is this possible? I still would like to use VirtualBox, because it seems to have better USB devices support and I have some network issues in Vmware too. Thank you for your answers
