Try to boot into the Safe mode (F8).
Do you still get the same message?
Thank you for replying back. Also, I'd like to apologize for not replying to you earliest.
In order to boot into the Safe Mode I have to select F1 or F2, It doesn't matter how I try to boot, the only choice I have is to press F1 or F2 first.
I have the latest updates available from Dell and Windows, the computer works fine at all times except for that annoying message I get.
I have a DVD/CD (LiteOn) writer connected in the secondary SATA port and that too have the latest driver available installed.
I'm not sure if the Bios is looking for a Hard Disk instead of a DVD/CD drive (if it makes any difference) therefore telling me that is not found.
Thank you for your help,
