Hi everybody, I stupidly deleted my boot file yesterday and I can't fix it with my USB bootable windows 10 installation. There's no restoring file either and the windows 10 USB bootable gives no option to just Reset my windows. So, far I have used the command prompt and tried the bcdboot repair and the answer always goes like this:

X:\Sources>Bootrec /fixmbr
The operation completed successfully.

X:\Sources>Bootrec /fixboot
The operation completed successfully.

X:\Sources>Bootrec /scanos
Scanning all disks for windows installations.
Please wait, since this may take a while...

Successfully scanned windows installations.
Total identified windows installations: 1
[1] C: Windows
The operation completed successfully.

X:\Sources>Bootrec /rebuildbcd
Scanning all disks for windows installations.
Please wait, since this may take a while...

Successfully scanned windows installations.
Total identified windows installations: 1
[1] C: Windows
Add installation to boot list? Yes(Y)/No(N)/All(A) :A
The requested system device cannot be found.

I have tried many ways and tutorials to find the mistake and repair this issue but nothing yet. Please help me. I'll upload everything my command prompt is showing just in case.

Hello Kattyv19,

Welcome to the Forum.

From what I can tell you have managed a potential repair perfectly, up until the final step:

Successfully scanned windows installations.
Total identified windows installations: 1
[1] C: Windows
Add installation to boot list? Yes(Y)/No(N)/All(A) :A
The requested system device cannot be found.
At this step you ought to select Y then press Enter to add the found installation to the boot list.

Assuming that action performs with no errors, you should then be able to close the command console, remove the Windows media you are booting from, and restart your computer normally.


Regards,

It ends with "The requested system device cannot be found." After I answer with Y (yes). I keep thinking the boot file is in another partition and that's where the mistake is. The disk 0 where my OS is located has 3 volumes:

VOLUME 1 NTFS partition 500 MB
VOLUME 2 NFTS partition 230 GB
VOLUME 3 NFTS partition 234 GB

The 3 of them are listed as active and I know my main files are located in VOLUME 3, because my Internal HDD is 500GB divided into 230 and 234 GB. I just can't figure out how to make a boot repair successfully.

Hmmm,

First, sorry I mistyped your username earlier. So hi Kattyv18 :)

If you're seeing a Device error, then it may help to completely rebuild the BCD store.

To do that technically you ought to delete the old BCD store, but given we cannot be sure there are not other issues creating this error lets be safe and simply rename it, so we can create a new BCD store and try again - then if that still does not work you can delete the new BCD store and restore the original one.

In that command console do the following:
  • Type bcdedit /export c:\bcdbackup then press Enter
  • Next, type attrib c:\boot\bcd -h -r -s then press Enter
  • Next, type ren c:\boot\bcd bcd.old then press Enter
  • Now you can try rebuilding the BCD again using the bootrec /rebuildbcd command.
If you succeed you can then repeat your previous steps remembering to choose Y on that last step.

Regards,

First of all, you probably need an 8 GB flash drive instead of a 4 GB one. Is it configured as GPT for some reason?

The 500 MB partition you are showing, can you tell us what it is?

You appear to have a Legacy install of Win 10, and so there needs to be an Active partition which contains the boot files. Can you tell us exactly what you did to "delete your boot file"?
