[Fix] Windows 8 or 10 Doesn’t Boot in HP Stream 7 with Error 0xc000000f

So, you tried to upgrade to Windows 10 from Windows 8.1 with Bing on HP Stream 7. But things went wrong as Windows 10 didn’t worked properly, as Microsoft is yet to roll out an update compatible with Stream 7 for Windows 10. So, the only option you have currently is to revert to Windows 8. But upon reverting process, many users are reporting that they’re getting error 0xc000000f and then installation halts. Also error 0xc000000f is very common for HP Stream 7 users and is one of the major startup issues. So, let’s fix this issue:

Fix Windows 10 Doesn’t Boot in HP Stream 7 with Error 0xc000000f

There are some pre-requisite to fix error 0xc000000f:

HP Stream 7 Error 0xc000000f

  • Powered USB Hub
  • OTG Cable
  • USB Mouse and Keyboard
  • Recovery USB

If you don’t have a Recovery USB, you can make one by downloading recovery image from this link. Instructions to make recovery USB are given in the zip file from link itself. In brief, i can tell you that it cleans the drive to FAT 32, set it to PRIMARY and Active. Then you just need to copy the files and folders from the image files to USB Drive. Be cautious while creating this.

Also, do not copy a generic Windows 8 or 8.1 ISO to USB drive using the Windows 7 USB/DVD tool or RUFUS. You must use WIMBOOT for this operation, or you’ll not get a compressed Windows and you’ll end up loosing more storage space than stock recovery.

You can install another edition of Windows 8.1 like Pro, assuming you have it and you’re making WIMBOOT image using that as source.

You can also install Windows Technical Preview if it get installed properly. (However i won’t recommend doing so)

  1. Connect the OTG Cable to USB Hub and Tablet and Power ON USB Hub only.
  2. Now connect mouse, keyboard and recovery USB to Power Hub.
  3. Now it’s time to turn ON tablet and boot it directly to BIOS by holding down Power + Volume Down button at the same time, until Stream 7 shows you the Startup menu.
  4. Navigate to System Configurations > Boot Options by pressing F10. Now we require to revert these settings at default.
  5. If Secure Boot is disabled, then first thing you need is to clear All Secure Boot Keys.
  6. Load HP Factory Default Keys to Secure Boot.
  7. Enable Secure Boot.
  8. Also ensure that UEFI boot order must be as follows:
    • OS Boot Manager
    • USB Diskette
    • USB CD/DVD
    • Network Adapter
  9. Now you need to reboot your tablet and return quickly to Startup menu. Hence, Save and exit Boot Options by pressing F10, and as soon as you press that, Tablet will restart. So, as soon as you press F10, hold the Volume Down button and then hit Yes.
  10. Assuming you’re back on Startup menu, Press F9 and select Boot from EFI File. Since, you have the recovery USB already connected to Power Hub, you will be presented with 2 options, i.e. RECOVERY and Other could be SYSTEM or any label (can vary for users).
  11. Select RECOVERY and then select bootmgr.efi.
  12. Tablet will restart and would boot from USB and shall start the Windows Recovery process.
  13. If asked, Select your Keyboard Layout and Navigate to Troubleshoot > Reset your PC using arrow keys. Now you’ll be presented with either of two steps i.e. Step 14 or 15.
  14. If the drive partition/boot manager is not damaged, it will ask for a recovery key. You can actually skip this step and hide the numpad, revealing the option Skip this drive if you don’t have the recovery key anymore, or just really want to start anew.
  15. If the drive partition/boot manager is damaged, the Reset will proceed and will ask you to Select A Target Operating System. In my case it was Windows 8.1.
  16. Now recovery would start, showing a screen of Reset Your PC. Hit Yes > Yes, Re-partition The Drives > Fully Clean the Drive > Reset.
  17. Tablet would go further and install the Windows 8 or 8.1 whichever applies to you again.
  18. Upon completion, you’ll be greeted by a BIOS screen asking if you want to clear the TPM Keys? Select Yes, and a new Key for the re-installed operating system, and you’ll have a HP Stream 7 with factory default settings.

If later on, Your HP Stream 7 is stuck on boot. And then suddenly it starts “Preparing Automatic Repair” but nothing really happens. Running System diagnostic finds no problem, but you might on a manual check on “System Information” screen that the “Born on Date” is “00/00/0000.” The primary battery date is “current/date.”

The only solution till now known is by Resetting CMOS. All you need to do is to leave the tablet, till it runs out of battery. You can also drain the battery faster by running diagnostic tests in UEFI startup. Navigate to

This shall drain the battery faster. Another way of spending battery fast is by inserting USB Hub on the tablet and don’t give Power to USB Hub. Connect Keyboard, mouse and any USB drive with it. This shall too drain battery fast.

Now, when you Power it back ON, tablet will show a message of “Resetting CMOS“. It should now work fine, but last thing you need to do is to update the EFI firmware to latest version. This shall stop the startup errors to repeat again.


  1. Hi, I am trying to recover my HP Stream 7 tablet. I have followed your instruction word by word (downloaded the Recovery image from your link) but as soon as I select the bootmgr.efi the HP logo appears with some spinning dots and after a few seconds tablet just turns off. What am I doing wrong?

    Also I don’t understand this bit “Also, do not copy a generic Windows 8 or 8.1 ISO to USB drive using the Windows…”. Does that mean that after downloading the recovery file and putting it on the usb drive I still need to copy Windows files onto it? (I din’t, thought the recovery file included the original Win 8.1 with Bing).

    Kind Regards,
