ran the windows repair on win10 and can't boot or anything
« on: June 12, 2019, 01:13:59 PM »
Microsoft tech support couldn't help, and tried to do a reset with keeeping my files but that didn't work.  Anything I can try to revert?  I have no restore points to use or image file etc.

I am now in Lazysoft recovery suite but doubt if anything there will help.

Thanks

This is what another member posted who had similar problems -

Boot with Windows installation DVD/USB, select repair and open a command prompt.

Type diskpart

Type select disk 0

Type list partition

then note the partition number where you installed windows.

You may need to list volume to identify the letter of the windows installation.

Type select partition X (X is the partition number where Windows is installed)

type active

type exit

type bcdboot x:\windows (where x is the letter of your windows partition)

What are you using to post on ?

If you don't have Win 10 install media but have access to another machine, you can create install media after reading the instructions at https://www.microsoft.com/en-gb/software-download/windows10

When you boot up with it, navigate to the Install screen and click on Repair your computer which will take you to the same advanced options as pressing and holding SHIFT throughout a restart.

Click on Troubleshoot and select Command Prompt.

For interest, how did the MS tech access the advanced boot options to try the Reset ?

I did a boot repair and am able to access advanced boot options, but none of them worked.

I am posting with my other desktop computer, also running win10.

Already tried the repair options and the "reset and keep files options" none of which worked.  It started to reset up to 30% then proceeded to undo all changes and went back to square one.

Based on this, will steps with command prompt still help?

I have this info from the boot repair:  Can this help?

Give those cmds a try.

What do you mean you did a boot repair ?

Can you press and hold F2 as you switch on to go into the BIOS to see if you have Secure Boot and if so, disable it.

Press F10 to Save and Exit.

If that doesn't get you in normally then execute those cmds as I've described.

I'm not sure if performing a chkdsk /f from that cmd prompt would help but you would first need to enter bcdedit |find "osedvice" to give you a partition letter and then enter chkdsk x: /f where x is your partition letter.

Let me know if you get an error message when entering either of those two cmds.

For clarity that is a Pipe symbol before find and is the uppercase of \

I've already passed this onto Shane and will contact him again so that he can read the Ubunto report.

I just entered the cmd's and and found my OS in partition 2, letter C.  Was just about to enter the boot command you gave me when I saw your new post.  Should I try to check the Bios first regarding secure boot?

I am doing the chkdsk now. It has deleted a bunch of "corrupt attribute records" .   It says "windows has made corrections to the file system. No further action is required".  No bad sectors.

Btw, Your help and quick responses are much appreciated.

The chkdsk may have done it so enter exit to close the cmd window, shut down and see if it will boot, otherwise execute that first lot of cmds to make the partition active.

You could check the BIOS for secure boot.

Couldn't find anything regarding "secure boot" in the bios.

Tried the cmd commands and got "Failure when attempting to copy boot files"


Below is the command I executed, then got above "Failure" message

X:=\windows\sytem32>bcdboot c:\windows

Try these cmds -

bootrec /fixmbr
 
bootrec /fixboot
 
bootrec /scanos
 
bootrec /rebuildbcd

If the /scanos reports no Windows installations found, try these cmds -

ren c:\bootmgr bootmgrbackup, where c: is where your Windows is installed

bootrec /RebuildBcd

bootrec /FixBoot

There are other bootrec suggestions in this article - https://neosmart.net/wiki/bootrec/#bootrec_ScanOs_doesn8217t_find_Windows

I'm going to have to shoot off shortly as it has turned 1:00am here in the UK.

Tried everything suggested but no luck. Windows OS is listed, but when I say "yes" to add it to the boot list - it says can't be found.  Crap

So Windows is not showing as a boot option at all.

I've never had much confidence in the Startup Repair in the advanced boot options, but give that a try.

What was the reason why you originally ran the Windows Repair program and did you use the latest version of 4.5.1 ?

Let's see if the machine will boot into Safe Mode.

 From Win 8 onwards, booting into Safe Mode has resolved some normal boot problems.

I'd forgotten about this cmd - boot up with the Win 10 install media and navigate to the Command Prompt and enter these cmds -

bcdedit

Look for the Windows Boot Loader - it will either be {current} or {default} then enter this cmd - I'm using {default} in my example.

bcdedit /set {default} bootmenupolicy legacy

exit

then shut down.

This gives you the old F8 options.

Tap F8 as you switch on and then select Safe Mode from the advanced boot options and press enter.

See if it will then boot normally after the restart, if it does boot into Safe Mode.

To revert the boot menu policy, redo the bcdedit cmd changing legacy to standard

bcdedit /set {default} bootmenupolicy standard

I came across this Boot Repair Disk but given the author's name, it may be similar to your Ubunto one.

https://sourceforge.net/projects/boot-repair-cd/

I selected Save on the download and used ImgBurn to create a bootable disk, but you may already have your own burner tool.

When i enter bcdedit, it says The boot configuration data store cannot be opened.  The requested system device cannot be found.
