Under the laptop there should be an area usually under the palm rest area with about 2 or 3 screws. Undo the screws and pop the plastic off and you should see a HDD ( hard disk drive ) . MAKE SURE YOUR LAPTOP IS OFF when you do this
The HDD is usualy just plug and play, you should not have problems with this easy peazee.
Remove it and place it back into the slot making sure it fits snug, you can start the machine up.. make sure that the HDD does not fall out of the slot!! - ( at this stage you can hear / feel if the drive is alive or not )
So I've been having exactly the same problem with my Aspire 5742G PXE-E61: Media test failure, check cable
PXE-MO: Exiting Broadcom PXE ROM
No bootable device -- insert boot disk and press any key
I tried, as said before onthe thread, to remove and place the HDD again on its slot, and when I turn on the laptop, the HDD makes no sound.
So, does that mean it's "dead" ? because i bought it like 2 months ago and haven't dropped it or anything! :s
