No bootable device - Windows 8.1 update

This question is not answered

XPS One 2710. I updated to Windows 8.1 via Windows store today. The installation went fine but it couldn't reboot because of "no bootable device". The setup/bios is set up on uefi mode/safetymode on. I've tried to disable safetymode or run in legacy but no luck. I have no bootable device and expected the installation to go just fine. Now what?

  • Ok. Resetting bios to default by pressing F9 rebooted the system. But now it is trying to restore the previous version of Windows and preparing automatic repair... Sad

  • I am having the same problem, was able to upgrade to 8.1 and all seems fine but after 15-20 minutes of inactivity...the Dell2710 reports no boot device available and sometimes also a critical corruption error.  I have to reboot then all is fine for another 20 or so minutes.
