1st Install VMware in your window terminal. As per my VMware 5.5 is good.
And from VMware setup (F2) select fist bootable device as CD Rom. VMware works
on only IDE VMware Hard disk, so remove SCSI HARD DISK from VMware. AND add IDE
Hard disk.
And then insert Ubuntu Linux and install the same.

If any queries let me know?

when I am on VMware, I assume there is a way of
removing SCSI Hard Disk and adding IDE hard disk, can you clarify?
