I have an Aspire XC-603 desktops and I recently purchased a another 2nd hand unit for backup. On the 'new' machine after the bios POST I get a black screen and a message:
"Insert boot media in selcted boot device and press a key"
If I take the hdd and put it in the second machine it boots ok. I have done the following:
- ensured that both machines have the same bios settings
- checked that the drive is seen in the bios
- checked the boot order
- switched the CMOS batteries and memory over
- disabled secure boot
The only conclusion is that the mainboard is damaged in some way? Is there anything else that I should check for, BIOS update perhaps?
Thanks,
Rob.
