Error Code 0xc000000f

Question

My son's laptop couldn't start properly and had an error code: 0xc000000f and it is saying that I need a recovery tool. Any information to help me fix this are truly appreciated.

Answer 1

DIsk Check checks and attempts to repair the files system that resides on the physical disk.

If it chokes it could mean the physical platter is failing which is only tested by Hard Drive Diagnostics. To test the hard drive with diagnostics: https://www.lifewire.com/free-hard-drive-testin.... Best is Seatools bootable Long Test which works on all models:

https://www.seagate.com/manuals/software/seatoo...

If the drive has failed I'd replace it with an SSD which is the best Upgrade one can have - lightning fast, faster than a new higher-end PC without one, especially if you do the gold standard Clean Install in this link which compiles the best possible install which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki...

Answer 2

Hi Irwin. I'm Greg, an installation specialist, 9 year Windows MVP and Independent Advisor, here to help you.

Unplug power and remove battery, press and hold power button for 30 seconds to release all power from circuitry, plug back in and power up to see if any change.

I will give you steps to access the Repair Mode to try all repairs to get Windows started, and if not to do the automated Reset or the superior Clean Install after rescuing your files. These steps don't cover possible hardware failure which might become apparent while performing the steps, so please report back as you go:

1. Use whichever method works in this link to access Advanced Startup Options: https://www.tenforums.com/tutorials/2294-advanc.... Easiest may be to force shut down the PC (by holding in the power button) three separate times to trigger the Startup Options. If one of these methods work, then go to Step 3.
2. If none of the other methods work it may be necessary to Create Windows 10 Installation Media on another PC: http://windows.microsoft.com/en-us/windows-10/m... Make sure to uncheck the box for Recommended Settings to choose only the licensed version.

If the Media Creation Tool will not cooperate use the alternate download site at https://tb.rg-adguard.net/public.php. Burn to DVD using WIndows Image Burner or create bootable flash using one of the options here: https://www.tenforums.com/tutorials/2376-create...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...

Choose the boot device as a UEFI device if offered, then on second screen choose Repair Your Computer. If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

3. In the Advanced Troubleshooting options try to System Restore to a point before the problems began, Startup Repair, then if necessary from Startup Settings try to get into Safe Mode with Networking, or lastly Safe Mode.

If Startup Settings aren't available you can force Safe Mode from Command Prompt following Step 5 here: https://www.digitalcitizen.life/4-ways-boot-saf..., or using the command to unhide F8 Advanced Boot Options here: https://www.tenforums.com/tutorials/22455-enabl... where you can also try the old reliable Last Known Good Configuration.

4. From Safe Mode w/Networking work through the Windows 10 Install Integrity Checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get donehttp://answers.microsoft.com/en-us/windows/wiki/windows_10-performance/windows-10-performance-and-install-integrity/75529fd4-fac7-4653-893a-dd8cd4b4db00: If it doesn’t fix Windows enough to start it normally, then try a Windows 10 Refresh: https://www.howtogeek.com/265054/how-to-easily-...

Update your drivers from the PC's Support Downloads web page. Compare the latest drivers with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

5. If Safe Mode doesn’t work or help stabilize things then return to Advanced Troubleshoot options. Next try Command Prompt to run through Windows 10 Install Integrity Checklist (above link) repair commands including sfc /scannow, DISM, a full Disk Check https://www.groovypost.com/howto/check-hard-dri..., or return to Troubleshoot options to Reset Your Windows 10 PC.
6. Better yet do the vastly superior Clean Install Windows 10 following the steps in this link to delete all partitions down to Unallocated Space to get it cleanest: http://answers.microsoft.com/en-us/windows/wiki...
7. There is a step to Rescue Files from the booted media or Repair Mode Command Prompt first: http://answers.microsoft.com/en-us/windows/wiki...

These steps are excerpted from my tutorial that compiles everything possible for Troubleshooting Windows 10 Failure to Start: http://answers.microsoft.com/en-us/windows/wiki.... You can continue with the other steps there.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Hi,

I am Sumit, an Independent Advisor and a 2-Year Windows Insider MVP here to help.

Let us try repairing the existing OS.

On a working computer, create an Installation media of Windows 10 that allows you to repair existing Windows Installation.

Create a USB Flash Drive

https://www.tenforums.com/tutorials/2376-create...

Boot from the USB Flash drive-Make sure you have disabled Secure boot/Fast boot in BIOS Settings.

https://www.tenforums.com/tutorials/21756-boot-...

https://www.tenforums.com/tutorials/21284-enabl...

Then open Advanced Startup options after the computer boots from USB. Click Repair your computer at the first screen that says Install now.

https://www.tenforums.com/tutorials/2294-boot-a...

Select Startup repair, let it finish the job and see if the computer can boot afterward.

If that doesn't help, consider doing a clean install after rescuing your files.

Answer 5

Hi Irwin,

I am Vijay, an Independent Advisor. I am here to work with you on this problem.

A. Try to boot into safe mode

Power ON your computer and as Windows / manufacturer's Logo appears, Power OFF - Repeat 3 times

Now your computer will go into Advanced Recovery Environment

Advanced Options > Troubleshoot > Advanced Options > Startup Settings > Restart

Press 4 or F4 to enable Safe Mode (5 or F5 to enable Safe Mode with Networking)

Log in once Windows starts in safe mode

See whether you able to login. If yes, come out of this and start normally.

If you are not able to boot like above, You will need to boot through a Bootable USB drive. You will need to create this on another computer which is working - https://www.tenforums.com/tutorials/2376-create...

How to Boot from a USB Flash Drive in Windows 10 - https://www.tenforums.com/tutorials/21756-boot-...

B. Another option when you are in Advanced Options in previous step is to choose (Note - You won't lose any files in this step)

1. System Restore - This will restore your system to a point when things were working fine.

OR

2. Startup Repair - Startup Repair upgrade fixes all Windows errors and retains all files, applications and settings.

C. Penultimate option could be Reset this PC.

In Step A > Troubleshoot > Reset this PC - Keep my files and Remove everything. Choose this carefully as most likely you would like to keep your files.

All apps will be removed and windows will be reinstalled.

D. Last option could be to Go back to the previous Build, if it was an upgrade to 1809 -

In Step A > Troubleshoot > Advanced Options > Go back to the previous Build

Do let me know if you have any more question or require further help.
