Are you able to get to the BIOS with the other hard drive plugged in? I find it hard to believe there's no POST screen at all.

strange but true first time I have ever seen this!! this is how I boot windows a from dvd disc in laptop with windows 8 installed Settings > Change PC Settings > General > Advanced Start Up. On the next screen select Troubleshoot > Advanced Options > UEFI Firmware Settings. Disable the secure boot. Restart and boot off dvd. but like I said the hard drive been wipe some how and their is no way of getting into bios!! im sure it something to do with the hidden file UEFI Firmware being deleted its driving me nuts

On startup, one of the F* keys is usually used to get into BIOS. F2, F10, or F12. Just try pressing them all on the BIOS splash screen when you first turn the system on.

its something to do with the UEFI Firmware that was on the hard drive I don't think you get a post on the new preinstalled windows 8 laptop as they boot from a hidden file on the hdd ?

UEFI is not on the HDD. UEFI is a BIOS feature. You need to access the BIOS.

My MSI wouldn't let me get into BIOS when I had hibernated it and then had to redo the bootloader. Ended up having to remove the main battery and then remove the BIOS battery to reset the BIOS. That ended up giving me the options to boot into BIOS again.

I would look to see if you are able to reset your BIOS by removing the CMOS battery; look for a small white plug, or someway to remove the CMOS battery on the laptop, without having to desolder it from the board.
