If you want to run an OS in a virtual machine you need adisk image in wich to run it. Use qemu to create this. [QEMU website]

create an image for VMware player:

Open a commnad prompt, browse for wherever you downloaded qemu, and run the following command:

• qemu-img.exe create -f vmdk c:/vmxp/hd.img 8G

that line above creates an image in the c:/vmxp dir with a maximum size of 8 gig, however ti will stretch upt to 8gig. -f is file system type vmdk for vmware.

if you make a vmware config file, stick it in the same dir as the image with the extention vmx (see VMWare_Config_Options). Make sure it is pointing to the right image file. Boot it and it should read cdrom or net and allow you to install an os.
