I've installed a 180GB SSD in an Acer Aspire V5-473P, and when it's first turned on I get a "No bootable device" error. If I then do a [Ctrl-Alt-Del], it reboots from the SSD reliably. Once in Windows, the system works perfectly well and the SSD passes all the diagnostics I can throw at it... I just updated the Acer's BIOS to v2.30 and the Intel SSD's BIOS is also current.
Back-storey and more details -
The Acer V5-473P is my daughter's and it has been running fine for just over a year now. I replaced the stock WD5000LPVX 500GB hard disk with a hand-me-down Intel 520 Series 180GB SSD that came from my own laptop which just got a newer/faster 500GB SSD :-).
On the Acer, I cloned the factory Windows 8.1 install from the stock HD to the new SSD using the EZ Gig IV software from Apricorn that came in a cloning kit with a USB v3 --> SATA cable. This went surprisingly smooth (and also on my own laptop from the Intel SSD to my new Crucial 500GB SSD).
Again, this "no bootable device" error occurs only on a cold boot after a shutdown (not on warm restarts), and the machine will boot correctly with a [Ctrl-Alt-Del] immediately after the error. It's like the SSD isn't quite ready by the time the Acer wants to boot after power on - but this is just speculation from the behavior... Any thoughts?
