I just installed a new 120 GB hard drive in my Sony Vio (2001). I took out the old one and put in the new. Simple. Now, when I turn it on, it says "Operating System Not Found". I press F8 when the SONY splash screen comed up and can bedin to use the Sony System restore disc. I asks me if I want to continue, then O press "O" for OK, then it takes me to another screen that says that the new drive is not partitioned and to press "Y" to partition. I press the "Y" key, but nothing happens. The same screen also says "If you see this screen again, it may be caused by Non-DOS partitions. You must delete the Non-DOS partitions to proceed"
Any suggestions on how I get the Operating System to work?
