My Hp All-in-One Desktop PC is not working

[Chris1391]

When I turn on my computer, I am prompted to enter the BitLocker recovery key. After entering the key, I receive a message stating that the computer has encountered a problem. Additionally, when I attempt to connect to the internet to perform troubleshooting, the computer does not accept any type of internet connection.

@Chris1391,

Welcome to our HP Community forum!

This usually happens when Windows detects a major system change or corruption and BitLocker protection is triggered.

Since:

• you can enter the BitLocker recovery key,
• but Windows still fails afterward,
• and internet/network troubleshooting does not work,

the issue is likely Windows corruption rather than only a BitLocker problem.

Things to try:

1.) Boot into Windows Recovery Environment (WinRE) :

• power on the PC,
• interrupt startup 3 times during the spinning dots/loading screen,
• Windows should enter "Preparing Automatic Repair".

2.) Try:

• Startup Repair
  first.

3.) If Startup Repair fails:
Go to:

• Troubleshoot
• Advanced Options
• System Restore

Restore the PC to a date before the problem started if restore points exist.

4.) If that also fails:
Open:

• Command Prompt as Administrator

Run (copy/paste/Enter) :

sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

Then:

chkdsk C: /f /r

5.) If networking still does not work in recovery mode:

that is not uncommon. Many recovery environments lack the correct Wi-Fi drivers. If possible, try:

• a wired Ethernet connection,
• or skip online troubleshooting entirely.

6.) Last resort options:

• "Reset this PC" (keep files) -at this point, a concern is that you could lose personal information. 

  If Windows starts, I recommend to copy important files to:

  - a USB flash drive,
  - external hard drive,
  - or cloud storage.

• or a clean Windows reinstall using a USB installer created with Microsoft Media Creation Tool.
• Use another computer: you can remove your SSD/HDD from the HP All-in-One and connect it to another PC using either a SATA-to-USB adapter or an external enclosure.

Before reinstalling Windows, make sure you still have your BitLocker recovery key saved safely, because encrypted drives may require it again during recovery.
