Windows 10 winload.exe error 0xc000000f

All,

When starting up my PC I get a blue screen with an error message stating that the file \windows\system32\winload.exe is missing or contains errors. The error code is 0xc000000f. It is asking me to insert the installation media, however I don't have this as I have upgraded to Windows 10 online.

Furthermore, I have noticed a severe decline in performance since Windows automatically updated 4 days ago. It now takes hours to start up my computer whilst this used to take 1-2 minutes (updates of 8 October 2015).

How can I get Windows 10 working again?

Your help is much appreciated!

Best,

Wouter

Hi Divya,

Thanks for your quick response and support. I have completed the steps that you have outlined in your response, however I have been unable to repair the system.

When I attempt to perform the Repair on this computer, I have followed steps a through c. However, when I click on 'Advanced options', the option 'Automatic repair' is not visible. The options that are visible are shown in the screenshot below.

When I attempt to repair perform a 'Startup repair', I get the error message that this option is not supported (as shown in the below screenshots).

What steps could I take to get Windows working?

I appreciate your help.

Best regards,

Wouter

Dear Jayant,

Thanks for your help so far. Unfortunately, following the steps you indicated in your previous message, has not resolved the issue. I am now getting a similar error message, this time with the code 0x000000e9. During the process you described, I also got a funny error message.

When I performed the Bootrec /rebuildbcd in DOS, it completed with the error message that there are 0 OS installed on the system.

It seems best to me if I do a clean install of Windows 10. Before I do this with the installation disk that I have burned as suggested in Divya's post above, I would like to know if there is any way I can move a dozen or so documents from the C:\users\myname\My Documents folder to an external USB drive. Is there any way to do this in DOS? Or are these files locked?

Your help with this issue is truly appreciated.

Kind regards,
Wouter

Dear Jayant,

Thanks for your response. Since my last response I have copied my last files to USB and now want to install a clean version of Windows 10, using the disk I have created.

When I attempt to reinstall Windows, under recovery options and choose to keep my files and settings, I get an error message saying there is a partition error.

When I attempt to install Windwos 10 from the root menu of the installation disk, I am asked for a serial number. Is it okay for me to enter my Windows 7 serial number at this point? Or do I skip this step?

Please help, it is much appreciated!

Kind regards,

Wouter

Hi,

Thank you for your response.

I would like to inform you that, once your device upgrades to Windows 10 using the free upgrade offer and activates online automatically, an entitlement is registered to your PC’s hardware for the edition of Windows 10 you upgraded to in the Windows 10 Activation service. So you can upgrade or reinstall Windows 10 anytime on your computer. If you have already upgrade to Windows 10, you may skip this step. However, you cannot manually enter the previous Operating System product key to activate Windows 10.

You may refer the follow help article and check if it helps.

Dear Sahil,

Thanks for your help. I have created a new install disk and managed to complete the Windows 10 installation. At the end of the installation, the message "please restart your computer in order to complete installation" appeared. I pressed on "okay" to restart. Since then, whenever I start up the PC I get a yellow screen.

Please see the attached screenshot for more information. I can still boot from the installation CD, but can no longer start Windows normally.

Thanks for your help so far, and hope you can assist further!

Kind regards,

Wouter

Hi,

Sorry for the inconvenience caused.

Based on the issue description I can understand that you are getting a yellow screen on startup.

This might happen because of the graphics card loading the drivers slowly or error while loading the content. Safe mode is a diagnostic mode where windows loads with minimal set of drivers and all the third party application will be disabled, in other words windows loads in VGA mode in safe mode and it will not use graphic drivers in safe mode.

Hence I would suggest you to try going in to Safe mode with networking and see if the issue persists.

If not I would suggest you uninstall and reinstall the graphics card driver and see if it helps.

Please follow the steps below to uninstall:

1. Right Click on Start, Select Device Manager.
2. Find and double-click the category of device whose driver you wish to uninstall, the graphics card would be listed under Display Adapters.
3. Right-click the device, and click Uninstall.
4.Windows will prompt you to confirm the device’s removal. Click OK to remove the driver.

5.After the uninstallation is complete, reboot your computer as soon as possible.

 
Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.
