I have an HP machine that freezes or reboots every time it starts (including safe mode). I want to run diagnostics on the machine but cannot boot to the DVD, the option is not available.
I have changed the DVD drive, used different SATA cables, Connected to different SATA ports, disconnected the HDD and disabled the network adapter.
When I go to specify the boot device it is not available but when configuring the boot order the DVD drive is visible.
Look forward to reading your suggestions.
