Windows 10: I need a Windows 10 1709 repair disk!

I'm looking for repair options.
Please post the commands if available for the problem or mistake.

For these images please make sure that the text is well seen on the images:

Open command prompt and type:
C:
dir
diskpart
list disk
list volume
select disk 0
list partition
select partition 2
detail partition
assign letter=b
list volume
exit
b:
dir
exit
bootrec /fixboot
bootrec /fixmbr
bootrec /scanos
bootrec /rebuildbcd
bcdedit /export c:\bcdbackup
attrib c:\boot\bcd -h -r -s
ren c:\boot\bcd bcd.old
bootrec /rebuildbcd
Y
reboot

It may take a couple of days to find alternative repair options.
There are ways to format the partition and rebuild the BCD.
I'm looking to see if a good resource can be found.

There are backup plans.
There is registry repair which can fix some boot issues, boot rescue and clean install.

 

well i found that mini disk wizard can repair the boot loader with out and worry about upsetting the partition

MiniTool Partition Wizard | Best partition magic alternative for Windows PC and Server i can recommend this software

 

Hi zbook,

I really appreciate tyour efforts on my behalf, I know how time-consuming research can be!

The last two chkdsk tests went through clean but this is the thing that I'm not sure about and I haven't been able to re-create it so that I can say N.

"I've been going through the list of commands you gave me and I remembered that when I first did the bootrec /rebuildbcd it came up with Total identified Windows installations: 0 and then when it asked me if I wanted to add installation to the boot list I very stupidly typed Y. I obviously wasn't aware of the implications and what it meant".

I will crack on with your list, I apologise for the poor quality of my mobile phone screenshots, I'm not sure that I can improve them but I will try.

do you mean the paid version or the free one? Just had a look at the free one options but cannot see anything about boot loader repair?

OK got it. The free version won't allow me to create a recovery CD which I need for the faulty system!

 

Maybe you did not make a mistake.
If there are 0 installations there is unlikely a way to add to the boot list.
So don't fret about it.
One way or another there are options.

If you want to try the reg backup that can be done with these commands:

Please take pictures of the commands and results and post images into the thread:

Let's see if this is a possible fix.


1) boot to the Windows 10 iso
2) it may take 5 minutes displaying the windows icon
3) Use the default settings for language, time, currency, and keyboard
4) click next
5) In the left lower corner click Repair your computer
6) click troubleshooting
7) click startup repair (it is expected to fail)
8) click system restore (it is expected to fail)
9) click command prompt
You should see a pop up with title bar: Administrator: X:\windows\system32\cmd.exe
This is the registry backup method:
For each step you must see sizeable file sizes for this to work.
If you see zeros the method will fail.
The command: dir
will be used each step to make sure you are in the proper location and check the size of the files
10) type: C:
11) dir
12) type: D:
13) dir
Choose the C: or the D: drive to proceed. It should be the windows drive and not the USB drive.
14) type: bcdedit | find "osdevice"
This should display the location of the partition and in most cases is the location of the affected drive.
For this post I will use C: however you should pick the drive letter that you found that has the windows files on your computer.
The proper drive will display: perflogs, program files, program files (x86), users, windows, etc
15) type or copy and paste: cd \windows\system32\config
It should display: C:\windows\system32\config>
16) type: dir
It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.
All of the file sizes should be sizeable. If it displays zeros then abort.
Make a new directory and name it backup or something similar.
17) type: MD backup
Copy all of the files into this new directory.
18) type or copy and paste: copy *.* backup
It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.
Change the directory to regback
19) type: cd regback
It should now display: c:\windows\system32\config\regback>
20)type: dir
It should display: default, sam, security, software, system etc
All of these files must be sizeable. If it displays zeros then abort.
21) type or copy and paste: copy *.* ..
It should now display:
DEFAULT
Overwrite ..\default? (yes/no/all):
22) type: a
It should now display: sam, security, software, system and that the files were copied.
23) type: exit
24) click turn off your PC
Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.


If the repair works then you must consider the repair fragile.
1) Make a brand new restore point
2) Backup all files to another drive or to the cloud
3) Make a backup image using Macrium:
Macrium Software | Macrium Reflect Free
4) Place the backup image onto another drive or into the cloud.
5) Check the Drive with HD Tune:
HD Tune website
Post images of the test results for these tabs:
a) Health (SMART)
b) Benchmark
c) Full error scan

 

download the iso win10 file from microsoft as previously mentioned either burn it as an image to dvd or make the bootable usb stick. the repair tools are in the iso win file

I'm not sure if I'm missing something here! I already have the Windows 10 iso on CD. I am currently using the Win 10 repair tools.

I cannot use the free Partition Wizard as it will not allow me to burn a recovery CD, I would have to buy the pro version.

I had already tried a similar function in, I think, Macrium Reflect but that didn't fix the fault.

 

zbook, before I commenced this perilous journey I did images to Reflect and Acronis True Image (which was the cause of all this as the restore failed), of my C;\, E:\, and F:\ partitions and I haven't been able to use the system since but I will do so again as you suggest, and also use HDTune.

Just about to start the bootrec stuff!

Thanks!

 

Problem!
I had got as far as assign letter=b
list volume
exit - takes me out of Command prompt back to the blue 'Choose an option' screen!

Surely I need to stay in command prompt?

 

OK, I continued on the basis that assign letter=b would be remembered so went back into Command Prompt and continued but came up with the same 'file not found bcd\boot!

 

The master boot record and boot partition got fixed.
Rebuilding the BCD did not work as it could not find the path.
Let's see what happens with the registry repair.
If that does not fix it use these commands to delete and rename the BCD:

Open diskpart > make sure the EFI partition is labeled
assign letter=b:


cd /d b:\EFI\Microsoft\Boot\
bootrec /fixboot
ren BCD BCD.bak
bcdboot c:\Windows /L en-us /s b: /f ALL
reboot

 

Ah, some progress!

Assuming it is OK to go for the delete/rename route could you please remind me of the commands needed to get me to the EFI partition to check if it says assign letter=b? Just in case I stray from the correct path!*Sad

Thank you. I will respond shortly.

 

In the image (post #23) that you posted volume 5 already is labeled B.
So unless you rebooted or used the remove command you should be ready to enter the commands.

What happened with the registry repair/backup in post #18

 

Post 18, I haven't tried that yet I think I considered it to be a bit more tricky so decided to carry on the current route so I can still go that way if necessary

 

Okay.
Let's see what happens after rebuilding the BCD store using the commands in post #24.

Please post images before rebooting.
