I have already dual systems : Windows 7 and Ubuntu installed on my laptop. The Windows 7 had been installed when I bought this laptop, and I don't have a CD.
I just installed VitrualBox under Ubuntu, hoping that I could install another Windows in this virtual machine, so that I could run some applications of Windows even under Ubuntu.
But it seems that I need a CD or ISO of Windows to boot inside this virtual machine. Otherwise, there is an error:
FATAL: No bootable medium found! System halted. My question is where I could find a CD or ISO?
At the moment, I am downloading ISO from this page, but do not know if it will work. By the way, I am not sure if I should pick the 32-bit or 64-bit? As my CPU is 64-bit but my Ubuntu is i386.
Could anyone help? Thank you very much.
