Hello,

My 2 year old Inspiron Mini 9910, with Windows XP operating system cannot find the Operating System.

When I start the computer, it goes through some of boot up sequence, then displays the message ""Operating System Not Found".   

I suspect the problem may be caused by a Malware infection, which I thought I had deleted.  The notebook was working fine for several days after I removed the infection.   I'm sorry I didn't write down what the infection was - this occurred a few weeks ago, before Christmas, and I was away on holidays when the notebook stopped  working.

I have the Operating System and Drivers and Utilities CDs that came with the new Notebook.  

    However, I do NOT have a portable CD/DVD drive, so cannot use these disks.  

I copied the Operating System disk files to  a USB device and changed the  "Boot up Sequence" to look at the USB device first.  

However, the  Notebook cannot find the  Operating system on the USB device, and gives the same error  ""Operating System Not Found"

How do I copy the operating system from the CD to the USB device, so the Notebook recognises the operating system?

Thanks in advance for any assistance.

Have a great day!  Julieanne
