[Hari1043]

my system is stuck in a automatic repair loop. I tried everything,system recovery is not working,tried installing my bios through a USB recovery flash drive. Now the system shows the following errors(inaccessible boot device 0×7B). Then the automatic repair screen showed this error(Driver PNP watchdog  0×1D5)

I have no idea what this means,can someone explain how I can resolve this.

My laptop:HP spectre x360 convertible 

Windows: 10

Ps: I am student and in dire need to fix my laptop,since I have all my semester deadlines and exams in the upcoming weeks. Thank you for your help

Hi @Hari1043,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I can feel the urgency being stuck in an Automatic Repair loop with errors like INACCESSIBLE_BOOT_DEVICE (0x7B) and DRIVER_PNP_WATCHDOG (0x1D5) right before exams is stressful. Let’s break down what these mean and how to fix them:

What the Errors Mean

• 0x7B (INACCESSIBLE_BOOT_DEVICE)
  Windows cannot access the system drive during boot. Common causes:
  • Corrupted boot configuration (BCD).
  • Missing or damaged storage drivers.
  • Disk errors or incorrect BIOS settings (e.g., SATA mode changed).
• 0x1D5 (DRIVER_PNP_WATCHDOG)
  Windows got stuck while initializing Plug-and-Play drivers during boot often linked to driver corruption or incomplete updates.

Step-by-Step Fix

Since recovery options failed and BIOS reinstall didn’t help, we’ll try manual repair from WinRE (Windows Recovery Environment):

1. Boot into Advanced Options

• Power on → as soon as the HP logo appears, press F11 repeatedly.
• If that fails, boot from a Windows 10 installation USB (you can create one from another PC using the Microsoft Media Creation Tool).

2. Open Command Prompt

• In Advanced Options, select Troubleshoot > Advanced Options > Command Prompt.

3. Repair Boot Configuration

Run these commands one by one: bootrec /fixmbr
                                                              bootrec /fixboot
                                                              bootrec /scanos
                                                              bootrec /rebuildbcd

4. Check Disk Health: chkdsk C: /f /r

(Replace C: with your Windows drive letter if different.)

5. Reset SATA Mode in BIOS

• Restart → press Esc or F10 for BIOS.
• Under Storage, ensure SATA mode = AHCI (not RAID unless originally set).

Save and exit.

I hope this helps.

Take care and have an amazing day!

I went to a service center and this is what the told me today,I don't know if it makes sense but can someone confirm if what they are saying is correct. The following is the the text I received from them 

 

Hi,

I checked your SSD and the issue is not with the storage cells, but with the internal controller of the drive. This type of failure is not detected by basic tests, which is why the software still shows “OK”.

However, the controller is corrupted and the drive is reporting impossible values. I’m attaching images where you can see:

an incorrect disk size,

missing or invalid boot sectors,

and even no serial number.

These problems cannot be caused by Windows — they only occur when the SSD’s internal controller has failed. That’s also why the laptop cannot boot when this drive is installed.

Unfortunately, in this condition we cannot recover the data.

If you need the information, it must be handled by a specialised data recovery company.

If you want to repair the laptop, the cost is:

66.60 € + VAT for the new SSD

59 € + VAT for the labour (including Windows 11 and Microsoft Office installation)

Total: 125.60 € + VAT

If you approve the repair, we will try to have it ready by tomorrow.

Please let me know how you would like to proceed.

Please let me know if this makes sense and whether I should go ahead with the replacement. Thanks
