Reboot loop with no access to troubleshooting

baresi · 03 Dec 2016

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

shows a bunch of block(?) errors

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.
