dear respected members, I hope u guys can help me in this, pls.

I have successfuly installed ubuntu and fedora in my virtual machines, but when it comes to boot on the virtual machine,it says,hardware acceleration is not present. with my own experience, i think its the problem of hardware. So is that hardware acceleration so necessary that installation wont go on without it? btw, my OS is windows 8 64bit.

thank you for your time and i am waiting here for your help. many thanksin advance.
