My dell xps 13 had a auto update from Microsoft, think it had to do with the video card, not sure.  It quit hibernating, going to sleep

I attempted a system restore to before the update and the laptop crashed.

 

Now it is in a constant reboot.  I can not get into the system except via a boot usb.

 

Not even a year old, bought 12/5/2016  

Win 10 installed

Reg Model  p54g

19.5v -2.31a

intel  core17

 

 

I made a boot usb of win 10

 

I can't add the info you ask for above as I can not get into the system

 

Thank you for your help.

 

 

 

 

Tried system restore:
says restart computer select an operating system then select system restore. 
there is no choice with booting into the ubs the lappy fails
 
Startup Repair
get startup  repair couldn't repair your pc
 
did command prompt
a. Boot from the Windows 10 USB recovery drive.
 
b. Click on Repair your computer.
 
c. Click on Troubleshoot and then select Advanced Options.
 
d. Click on Command prompt and type the following commands and press Enter after each command:
 
Bootrec /fixmbr
 
Bootrec /fixboot
 
Bootrec /rebuildbcd
 
e. Restart the computer.
 
f. Check if the issue persists.

Can you tell us what Version (probably either 1607 or 1703) and Build Number (probably 14093 or 15053) your machine was running?

It says microsoft windows [version 10.0.15063]

 

But in thinking this out I think it is just seeing the usb disc not the computer disc.   It says size is 29 gb, which is the usb not the lappy hard drive.

 

when I do x\:sources>diskpart

then select disk

 

How do you make it see the lappy hd?

Are you able to access the built in Dell diagnostics?

To do this, tap F12 repeatedly as the system first starts.

This should lead to a menu where you can select the Diagnostics.

Run them all and let us know the results

FWIW - if you fail any of the diagnostics, I'd advise seeing how you can get it repaired under warranty (most warranties are 12 months from purchase).

 

Good luck!

OK, that means that it's not likely to be hardware (although the tests don't test everything).

 

As you can't get it to boot to Windows, there's limited things to do.

You'll probably want to backup your data first, then here's a list (in order):

 

NOTE:  Try a clean boot to see if the problem clears up that way:  http://www.thewindowsclub.com/what-is-clean-boot-state-in-windows
If it does, then different troubleshooting steps are called for.

Here's some repair/recovery/restore options (in this order).   Be sure to backup your stuff if you don't want to take the chance of losing it.:

 

1 - Startup Repair.  Run it 3 times, rebooting in between tries.

2 - System Restore to a point before this started happening.

3 - DISM/SFC repair (DISM doesn't work with W7, although SFC does)  - doesn't work if you're not able to boot to Windows (I've posted the offline version in the next quote box below)
    

 

Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt).  Press Enter after typing it:
   
Dism /Online /Cleanup-Image /RestoreHealth
    FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

    From this article: http://technet.microsoft.com/en-us/library/hh824869.aspx

    You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption. Include the CBS log (located at C:\Windows\Logs\CBS\CBS.log) if you'd like to have a Windows Update expert check it (I don't check them because I can't read them)


4 - RESET using the "Keep My Files" option (W8 calls this a REFRESH; W7 and earlier doesn't have this function)

5 - Repair install of the OS (Thanks to FreeBooter!):

    "Non-destructive reinstall of Windows XP"
    https://www.winhelp.us/non-destructive-reinstall-of-windows-xp.html


6 - RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)

If using W7 or earlier, this can be accomplished by resetting the system by use of the recovery partition/recovery disks/recovery drive.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

7 - Wipe and reinstall from the Recovery Partition (if so equipped)

8 - Wipe and reinstall from Recovery Media - to include deleting all partitions.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )
  You can also download W7/8.1/10 from Microsoft starting on this page:  https://www.microsoft.com/en-us/software-download/

 

Offline DISM and SFC:

 

DISM /Online should only be used when running from within Windows. Run this command instead:

Dism /Image:C:\ /Cleanup-Image /RestoreHealth
Did you also try doing SFC scan while booting off of Recovery Environment or Install Disk? In those cases, the commands are slightly different:
sfc.exe /scannow /offbootdir=c:\ /offwindir=c:\windows

I read the above, it appears all of that depends on getting into windows, which I can't.   f12 let me into repair, I did a repair it says unable to repair the problem, do a restore.  The restore they are saying to do, is back to factory level, not a restore point.

 

Any other thoughts before I kill my computer?  I did make a backup of files.
