Lenovo ThinkStation P300 - Manual (Page 68)

A CD or DVD does not work
Solutions:
• Ensure that the disc is inserted correctly, with its label up.
• Ensure that the disc you are using is clean. To remove dust or fingerprints, wipe the disc clean with a soft
cloth from the center to the outside. Wiping a disc in a circular motion might cause loss of data.
• Ensure that the disc you are using is not scratched or damaged. Try inserting another disc that you know
is good. If you cannot read from a known-good disc, you might have a problem with your CD or DVD
drive or the cabling to your CD or DVD drive. Ensure that the power cable and signal cable are securely
connected to the drive.
Unable to use a bootable recovery medium, such as the Product Recovery CD, to
start your computer
Solution: Ensure that the CD or DVD drive is in the startup sequence before the hard disk drive. Refer to
“Selecting or changing the startup device sequence” on page 40 for information on viewing and changing
the startup sequence. Note that on some models the startup sequence is permanently set and cannot
be changed.
