Cannot boot from DVD or CD

[Forch]

Hello all...  I have a W700, Type:2758.

I have formatted my drives and I want to re-install the O/S.  When I power up the machine with a disk, the message I get is "Device not found" or "No valid operating system".

1.  My boot order has "ATAPI CD0: Model HL-DT-STDVDRAM GT33n-(TS)" as the FIRST device.  This device has "No valid operating system" written beside it.

2.  I have two disks I am trying to boot from.  The first is a Windows 7 boot disk, and second is the BIOS CD that I got from the Lenovo site.  My results are the same regardless of which disk is in the DVD drive.

3.  I have swapped the DVD-Drive with a co-worker to ensure that it is working correctly.  The DVD drive does in fact work.

4. I have checked both disks on my other PC and I have no problems reading them.

Any ideas?

Thanks!

Never mind..... I got a hold of a USB DVD, and taaa-daaaa, it sees the disk instantly.

While I am still completely confused on why I cannot boot from the built-in DVD, I at least can install the O/S now.  (Again, I have even changed the embedded DVDs...)

Oh well......

Have a great day everyone.....
