A few days ago my Lenovo desktop M93P started up and showed me the below message:

 

Your PC/Device needs to be repaired.
An unexpexted error has occured.


Error code 0xc0000001

You'll need to use recovery tools.
Press Enter to try again
Press F8 for Startup Settings
Press Esc for UEFI Firmware Settings

 Trying again did not help. All options behind F8 brought me back to the above display.

 

I have then taken the following actions already:

1/ I ran all the Lenovo diag tools to see my C drive was still ok, nothing came out of this.

2/ Since i did not have the original install CD of Win 10, i created a USB recovery drive (key) on my Lenovo Thinkpad also running on W10.

 

I then booted this recovery usb key and already took the following actions

I booted from the recovery key, then  click Troubleshoot > Advanced Options > Command Prompt.

Then i ran the following commands:

Bootrec /fixmbr

Bootrec /fixboot

Bootrec /scanos

Bootrec /rebuildbcd

But the Bootrec /rebuildbcd wouldn’t work with a error  “The requested system device cannot be found”

 

Then i ran following commands:

diskpart

select disk 0

select vol 3 (this is my Efi partition that is formatted FAT32)

assign letter =G

bcdboot c:\windows /S G /f ALL

 

However, i am stil stuck with my error 0xc0000001...

 

All suggestions are appreciated.

Paul.

Have tried Startup Repair tool?
Have tried booting Windows into Safe Mode.


Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

Please type below command into Command Prompt and press Enter key.

The following command scans integrity of all protected Windows system files and repairs files with problems when possible.

Sfc  /Scannow   /OFFBOOTDIR=D:\   /OFFWINDIR=D:\Windows

Please replace partition letter D: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

Hi Freebooter,
tx for the reply,

The startup repair tool (so when i boot from my c:\Windows drive cannot repair it (i tried this several times),
same accounts for starting in safe mode. This is one of the options behind the F8 key and this brings me almost immediately back the menu where the 00000°1 error is displayed.
I have no W10 setup media.... The only thing i have is the "recovery USB key" i created on another W10 PC.
Can i also run the SFC command from the "command prompt " after i boot with this recovery key (and then advanced tools \command prompt) ?
I'm currently not at home so i cannot test it right now...
thanks.
Paul

As long as you can start the Command Prompt recovery drive you can run Sfc command.
If you want to you can also create latest version of Windows 10 Setup Media with Windows 10 Media Creation Tool.

Hi Freebooter,

 

tx, I ran the sfc command, it runs for quite a time and then displayed a message saying: "Windows resource protection did not find any integrity violations"...

When i ran the "BCedit" command, i got a message saying that no boot configuration could be opened. Second message under this line " the requested system device cannot be found"

I ran the diskpart again and i see that i have on my C drive, 5 partitions of which 4 are hidden: Windows8_OS, WinRE_drv, System_drv, one with a blank label and finally also "Lenovo_reco".

The Windows8_OS comes from the fact that i bought the PC with W8 but upgraded it about 2 years ago with W10.

Thanks,

 

Paul

The following example initializes the system partition by using BCD files from the C:\Windows folder:

bcdboot C:\Windows /f ALL

After executing above command execute following command.

Bootrec /rebuildbcd

[Paul432220]

Hi FreeBooter,

The first command gives an issue, in the sense that it displays the full help of the command, so something is missing in t he above syntax, it looks to me from the displayed command syntax, that the /f parameter means you

should also have the /s parameter in the command, but what volume should i point the /S parameter to ?

Because of this issue, i did executed the 2nd command...

thanks, Paul

[FreeBooter]

You don't need to use /f parameter please execute following command.

bcdboot C:\Windows

[Paul432220]

This command gives following return

"Failure when attempting to copy boot files"...

 

thanks.

[FreeBooter]

Make sure Windows folder located at C:\ partition by executing following command:

Dir C:\Windows

[Paul432220]

My windows directory is indeed on the C drive (c:\windows), i can see it it the command prompt (when i booted the W10 rescue key)...

Not clear to me what you want me to do next, i just tried to run the bcdboot command from within the c:\windows directory, the result remains as i communicated higher...

thanks.

[FreeBooter]

Mark EFI system partition (ESP) as active then try bcdboot command.

[Paul432220]

I attach a picture that shows what volumes i see after having started diskpart from the command prompt (booted with the USB recovery key i made).

The C disk is where my W10 is installed, the D drive is my data disk (no issues with that).

To be sure, what volume would be the EFI volume, the "system_drv" volume ?

thanks.

[FreeBooter]

You need mark System volume active.

[Paul432220]

Tried setting the system volume active and then afterwards also the system partition, but message is identical, "the active command can only be used on fixed MBR disks"...

See also attached picture (where you only see this message for setting the system partition active)

thanks
