Device Encryption Failures

[Shiqi000]

Hello, I have install Ubuntu side-by-side to Windows 10 by partitioning my drive. Then I was ask to enter the Bitlocker recovery key when I want to boot into Windows.

I searched online to find out that this is because Windows does not think GRUB as a secure component. So I disabled security boots, and turned-off the Device Encryption in Windows (setting - Update & Security - Device Encryption - turn off).  Finally, I can directly boot into Windows without being asking for recovery key.

Then I enable security boots and want to turn-on Device Encryption. But Device Encryption is no longer in setting - Update & Security page. So I checked System Information. It says:

Device Encryption Support    Reasons for failed automatic device encryption: PCR7 binding is not supported, un-allowed DMA-capable. 

Other Information that might be helpful:

Secure Boot State: On

PCR7 Configuration: Binding Not Possible

Any help? Thank you very much!

You should have done MORE research on dual-boot issues before you did the side-by-side option -- because that has a KNOWN history of corrupting the Windows filesystem as a side-effect of that kind of installation.  

And, that prevents fixing the Window install because a corrupted filesystem will not boot properly.

Also, if your Windows install was encrypted, that pretty much guarantees that installation will destroy it.

We can do nothing for you from  here to fix the damage.  You will need to look into ordering HP Recovery Media to restore your PC to its original state -- without the Linux install.

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 (650) 857-1501.

If HP no longer provides Recovery Media for your model, another site you can check is: http://www.computersurgeons.com

When you get the media, if it is a USB stick, insert it into your PC, pressing F9 to get a Boot menu, then select the External USB Hard Drive to boot from it.
