Your PC needs to be repaired. A required device isn't working or can't be accessed

Hello I have a HP Stream 11 that was working fine until I tried to reset it. The reset went good but when I went to turn on the computer it stayed in a boot loop. I looked up some stuff online & it would tell me to press F11 but when I do it takes me to a recovery screen & says that my HP needs to be repaired. It also says that a device isn't connected or can't be accessed. Error code: 0xc000000f

Hello;

Allow me to welcome you to the HP forums!Hello;

We need to know which OS version is running: Win7, Win8, Win10.

And if was running Win10,  did the PC come preinstalled with Win10? Or, did you upgrade it from a prior OS to Win10?

This is important as the recovery/reset method is different for the two situations.

We can proceed once you provide the information.

Thanks

I believe it came installed with windows 8 but it provided me the option to upgrade to win 10 so I took it. Its been a while that it has been like this so I don't remember too well

Unfortunately, upgrading a Win8.x PC to Win10 presents a serious problem when it comes to doing a system recovery.

The Win10 Upgrade is know to corrupt the Recovery partition stored there by the OEM that built the original machine. This pretty much guarantees that no HP Recovery is going to work: http://h30434.www3.hp.com/t5/Desktop-Video-Display-and-Touch/HP-Recovery-Manager-Blocked-After-Windo...

This means that RESET no longer works on your laptop due to your doing the Win10 Upgrade.

To actually restore your PC to its original condition, you need something known as HP Recovery Media.

HP Recovery Media is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utilities. In some cases, you may be able to order a USB stick instead of disks. You have to order these from HP; they can not be downloaded.

You can look online for Recovery Media starting with the linked paged: http://support.hp.com/us-en/drivers

Once there, input your Product name or number. On your Software and Drivers Download page, select your Operating System and and Version. Click "Update". If HP Recovery Media is available for your machine, down near the bottom of the page, you will see an entry for Order Recovery Media-CD/DVD/USB. Click the "+" symbol to expand that entry and click on Order Media for details.

Or, if you prefer, you can do the same by contacting HP Customer Service:

If you live in the US or Canada, contact information is on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

If you live elsewhere, contact information is on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!

If you have trouble finding a phone number, then try: 1 (800) 474-6836

If HP no longer provides Recovery Media for your model, a couple of other sites you can check are: http://www.computersurgeons.com/ and http://www.restoredisks.com/

Once you have the media, read through this: http://support.hp.com/us-en/document/c00006110

Good Luck
