Re: No Bootable Device/No Recovery - Dell XPS All-In-One

This problem may have many causes and is hard to pin down exactly what is happening.

When you look at your Boot Device Menu, there should be a Windows Boot Manager.  If there is, choose it and continue booting.  Some of the situations involved may range from a bad drive to corruption in the Boot process, whether it is the original boot files or follow on files required to complete the boot.

The Bootrec /scanos will look for any installs not already listed in the BCD store.  It may or may not help but the Rebuildbcd may.  During an upgrade, the Boot process is changed in several ways and is supposed to be restored prior to finishing the upgrade process.  If part of that is not completed, your system is left in an unknown state.

If you can get into the Command prompt, try running the command below and see if you can get us a picture or a copy of the readout.  This shows the BCD store and should confirm if it has the required entries.

bcdedit

Other command which might be useful, under specific conditions are the bcdboot command which will replace the BCD store with a copy of the template in the Windows folder.  So the command depends on the correct drive letter for the OS partition.  It is normally C but you can determine that by using Diskpart first.

diskpart

list vol

exit

Use the drive letter of the of the Windows partition in the command below where C is.

bcdboot C:\Windows

If it works, your system should boot but you should make sure the Windows Boot Manager is set as the primary boot device in the Bios.

If the system does boot normally, then you may want to run the bootrec /rebuildbcd command again.

Re: No Bootable Device/No Recovery - Dell XPS All-In-One

See attached pic after running the bcdedit command. I then tried the bcdboot C:\Windows, and get a list of 25-30 different possible commands (Extend, Format, etc). Is this a "normal" boot, or am I expecting something else?IMG_0292.JPG

Re: No Bootable Device/No Recovery - Dell XPS All-In-One

You attachment shows some differences from my system.  The note at the top about Not enough memory looks a little strange..

But otherwise, it looks normal.  As long as you have the Windows Boot Manager selected as primary boot device, it should boot normally.  If the system is not seeing the drive and cannot find the BCD store, then we need to find why it is not seeing the drive, since you can see it in the command window.

One thing I would like to confirm is that the GUID numbers for the default and displayorder in the Windows Boot Manager agree and that same GUID number shows as the identifier for the Windows Boot Loader.  Or, are they all three the 94cce5b7 number..

Use this command to show GUID numbers for all entries.

bcdedit /v

There was, at one time, a procedure for setting up another mount on a drive which would allow the system to boot to that.  It was done in the Bios and pointed at another folder on the EFI system partition.  I will need to find those threads to see if that might be relevant.

Edit:  This is one thread you might check.  I have not actually done this so I cannot guarantee anything.  Since the instructions are for another system, where certain options may be located could be different for your system.

Of course, if it is a 2720, it could be old enough for a hard drive to fail.
