Hello,

 

My son has a Dell Alienware computer that seems to be stuck in the automatic repair cycle. He was watching YouTube and got the BSOD, then went into the auto repair loop.  We have tried searching online and doing the recommended fixes (rebuilding the MBR and BCD, booting from a USB with Windows 10, disabled early launch malware protection, tried booting into safe mode) with no luck. Right now the screen is at recovery options. He is 10 and has a love for programming, and has tried to research the issue as well but we can't come up with any fixes that get us anywhere.

 

He's had the computer for just over a year. It's a Dell Alienware 15 R2 with an Intel Core I7 processor and a GTX 970M video card.

 

If anyone could help, we would be most grateful.

 

Thanks!

 

Fabienne

Read the below post twice. It may be possible to recover the computer by copying the backed up registry hives in the Regback folder if they have a date before the problem and they are not zero bytes.

Thank you. I have read through the post twice and am trying to go through the steps. Forgive me if I'm being dense, but I'm stuck here:

 

you will see a X:\sources prompt, default is X:\Windows\System32> at this we type...

 

I do see the X:\sources prompt. How do I get from there to X:\Windows\System32>  ?

I'm assuming you have already did the command of 

 

Bcdedit | find “osdevice”

 

To find your OS device drive letter.

 

At the X:\sources prompt you should be able to simply type the OS drive letter. i.e. if "D" in the Bcdedit command type;

D:  <enter>

Edit: The above will not work because Bcedit is in the System32 folder, sorry. Change the directory to System32 as shown in the below cd command.

 

Change to the X:\Windows\System32  folder using the below command.

cd X:\Windows\System32

I can't get the find osdevice command to return anything. :/

 

X:\sources>Bcdedit | find "osdevice" 

 

returns me to X:\sources>

 

If I type

 

cd X:\Windows\System32

 

then I get

 

x:\Windows\System32>

 

So I tried the command again at that prompt:

 

x:\Windows\System32>Bcdedit | find "osdevice"

 

Again, that just takes me back to

 

x:\Windows\System32>

 

 

Thank you for helping.

At X:\Windows\System32 type:

dir bcdedit.*

does it return the file name?

 

Edit: If you get bcdedit.exe from the dir command type:

Bcdedit /enum | find "osdevice"

Does it return to the System32 prompt without an output?

For some reason it cannot find a OS device.

 

At the command prompt type:

 

diskpart

list disk

select disk 0

list volume

 

post a screenshot or output.

I assume Volume 1 is a USB flash drive of your Windows 10 install. It seems your EFI boot partition is missing. There should be another volume formatted as FAT32 and listed as a EFI system partition. 

 

There is only one hdd on this computer? What was the output of list disk?

Yes- it is a USB flash drive with Windows 10. My son says the computer also has an SSD.

 

Output of list disk:

 

Disk ###       Status       Size       Free     Dyn    Gpt

---------------   ------------   ----------  --------  --------  -----

Disk 0           Online       931 GB   0 B                  *

Disk 1           Online         14 GB   0 B

Something is seriously wrong. You show a data partition of C: but no EFI system partition.

 

At the X: command prompt type:

c:   <enter>
dir *. <enter>

Is a Windows directory listed?
