Welcome to LQ!
What about your boot preference hotkeys? Some use F11 or F12 to select the boot device.
What does your manual show for BIOS entry? Since the New Year, jeremy has requested all crystal balls to be shipped back to LQ. New in-plants on their way so we can read each others mind via the inet. ooops!
Some hardware information might help?
I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem/query.
