Windows 10: Reboot loop with no access to troubleshooting

Hi all,

Using a Sony Vaio laptop (VGN-NW270D) that originally came with 64bit Windows 7, it was upgraded to 10 earlier in the year and the only issue was every once few times (at most only 20% of time) waking up from sleep would not turn on monitor (external neither) but by its lights I could it see it's running, reboot by holding power button would bring it back to normal. I guess this last time it caused errors. After similar reboot it is stuck on a repair boot, first "Diagnosing" then "Automatic repair" and then "Repairing...this could take an hour" but every time it reaches 34% goes back to "Diagnosing". I searched for ways of trying to reach windows 10 troubleshooting screen like catching it right after reboot, pressing F8, etc but that Windows 10 screen never seems to appear for me to try to troubleshoot via there. Are there sure ways to get to it?

I tried a Fedora live CD I have and it doesn't load and shows a bunch of block(?) errors, then used Puppy Linux one and it mounts/loads, but with an error, but at least it seems to mount the drive and am copying personal files to a USB flash just in case.

I did fdisk -l to show here but took a pic to also show that ntfs mount error.

Any one of those WinRE can be used to fix errors and recover? or perhaps downloading 10 iso? ... best way to proceed to fix.

Thanks

:)

 

Win10 reboot loop and troubleshooting issues

Hi Erick,

Thank you for posting the query on Microsoft Community. I am glad to assist you on this.

I would like to know few more details on the below questions to understand the issue better.

1. Did you try to upgrade to Windows 10 via Windows Update or an Installation Media?

2. Which OS did your system had before installing Windows 10?

3. Is your Windows 8 is activated prior installing Windows 10?

We can freely upgrade to Windows 10, if we have Windows 7 with service pack 1 or Windows 8.1 with all the updates.

Please do get back to us with the answers to assist you better with issue you are facing.

 

Win10 reboot loop and troubleshooting issues

Hi everyone,

So recently my notebook suddenly has reboot loop issues, so at this point I cannot get to my log in screen

After researching the issue, I tried following the the answer from Windows 10 Restart loop

The thing is that, as I tried the Startup Repair, it says it couldn't repair my PC and there is some kind of referencing to log file: C:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt

Then i tried command prompt, what I found after I input command bootrec /scanos and /rebuildbcd is that it says there are 0 windows installation identified.

When I tried to reset my PC with removing all my files, it also says there is a driver partition missing.

When I tried to install windows, the primary disk falls under OEM type and it says I can't install it there.

At this point I am really lost and don't know what to do

Also, I sadly couldn't revert to the previous OS, I'm not sure why.

My notebook is Razer Blade QHD+ intelcore i7 4720HQ and 16GB Memory. It was preloaded with Windows 8 and I upgraded it myself to Windows 10.

I am not that tech-savvy so If anyone could give a detailed instruction on how to resolve it, it would be much appreciated.

Thank you so much beforehand.

BEHAVIOUR UPDATE:

Now I do not need my Windows 10 Installation USB again to get pass the boot screen. Now It will start to do "automatic repair" but then it will fail and able to continue to blue "advance option" screen that I attached the image. Still unable to go to log
in screen though.

 

This would mean that your HDD has some Bad Sectors or Blocks of sectors.
If you were able to recover your files, then run Check Disk on the drive.
Boot into a WinRE disc and get to the command prompt. Find the drive letter for the OS, (it may not be C:) at the X:\Sources> Prompt type C: and press Enter. At the C:\> prompt type DIR and press enter. If there is a Windows directory. that is the OS drive. If not, type D: etc.
At the OS drive, type chkdsk /R and pres enter. Now type a Y for yes and Reboot the computer. Check Disk will start at next bootup and it will take a while.

 

Thanks. Could you elaborate what you mean by 'Boot into a WinRE disc'? I have to download a specific one or which should I use?

 

It sounded like you were familiar with a couple?
If you have a Windows 10 install Media, boot off of that Choose your Language and the press Shift+F10 to boot into the Command Prompt.

 

Oh yes, thanks again. Will be back with results later.
