Desk top says recovery your PC needs to be repaired

[JHigby]

HP 21-h116 (with touch screen)

Screen says: Recovery your PC needs to be repaired when I turn it on. It says the boot configuration data for my pc is missing or contains errors.  

File:\EFI\Microsoft \Boot\BCD

Error code:0xc0000185

"You'll need to use the recovery tools on your installation media.  If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer."

Please help!!

This is a fairly new computer and not used very often.

@JHigby -- This is a fairly new computer 

Less than one year old, where the original one-year HP Warranty is still in effect? If so, exercise the warranty, to get the computer manufacturer (HP) to fix it, at their expense.

There are several possibilities:

* corrupted file(s) on your disk-drive,

* corrupted file-system on your disk-drive,

* defective RAM, causing unpredictable errors when that stick of RAM is active,

The on-screen advice is good, but only if you, or a computerphile friend, or a professional computer technician, understand and can follow that advice.

Your EFI-Partition got corrupted and you have to write a new BCD.

This is the right command to create a new BCD

bcdboot C:\Windows /l en-us /s B: /f UEFI

But you need a PE-Medium first to run >>diskpart<< because you have to choose the right letters. 

Otherwise your data are lost!

If you know how to do it, the problem is fixed within 5 minutes.

@JHigby --  "You'll need to use the recovery tools on your installation media.  If you don't have any installation media ..."

If you don't have the media, you can create one.

1. Find a working PC, with an Internet connection, and 10 MBytes of "free" disk-space.
2. Find either an 8 GB (or larger) USB memory-stick or one blank DVD-recordable disk.
3. See: Download Windows 10 (microsoft.com)  Choose either to write the download to the memory-stick, or to "burn" the download onto the DVD-recordable.
4. Connect the memory-stick to your own computer, or insert the DVD into the CD/DVD device.
5. Power-on your computer, and immediately press the ESC key.
6. Choose "Boot Menu".
7. Choose either the memory-stick or the DVD.
8. Boot from your choice.
9. You'll soon get to a window that offers "install" or "Repair".
10. Choose "Repair".
11. Cross your fingers, toes, and eyes, that the "repair" will be successful.
12. Shutdown the computer.
13. Remove the memory-stick.
14. Power-on the computer, and remove the DVD media from the device.
15. Let the computer boot from your "repaired" disk-drive.

This process seems to require less technical knowledge than using the "WINPE" (Windows Pre-Execution) tool, and the "DISKPART" command.
