The DVD does boot another laptop, so ISO image on DVD is OK.
I ran diagnostics on the system, it is OK, so DVD drive is OK.
Next, I downloaded drivers for Windows 7 and added them to the DVD.
Now, when I select DVD as the boot device, I get the following message:
Reboot and select proper Boot device
or Insert Boot Media in selected Boot device and press a key
(it keeps repeating, the DVD is in the drive.)
If I select HDD as the boot device, I get the error message (as before):
PXE-E61: media test failure, check cable
PXE-M0F: exiting PXE ROM
Q) Does this have anything to do with the coin cell battery? Does it need replacement?
If the DVD works in another system, it sounds like the DVD drive is bad - either replace it or use an external USB DVD drive (or make a USB flash install drive) to install the OS.
I finally got it fixed!
The PXE-E61: media test failure, check cable error was caused by the system trying to boot to the network.
To fix it, on boot up, press F2, Setup -> Advanced, change setting of Integrated NIC to Disabled.
Next, I burned (not copied) the Windows 7 ISO file to a flash drive and installed Windows 7, it worked that way.
Next, there were a lot of Windows 7 drivers to be installed and then updates to be installed. It took several hours, it was painful.
Now, I have a working laptop, but I need to reinstall a lot of programs and recover data from the failed HDD.
my Inspiron 1545 will not boot from DVD even though the drive spins up when a disc is inserted even with onboard NIC diasbled .. Cable Hardware Detect test passed when I ran the onboard diagnostics Suggestions ?
Is the BIOS set to boot from the DVD drive first? Have you tried selecting the DVD drive from the F12 boot menu? What disc are you trying to boot from?
