If you see a Stop Error – 0x7B INACCESSIBLE_BOOT_DEVICE after applying Windows Updates on your Windows 10/8/7 system, know that it is the result of the boot state that the system gets. Microsoft has laid down some steps that will help you address this issue. Let us take a look at them.
0x7B INACCESSIBLE_BOOT_DEVICE Blue Screen after Windows Updates
When you get the 0x7B INACCESSIBLE_BOOT_DEVICE error, you might be at a loss. Maybe you can’t even understand the problem, but don’t worry, that is only normal. What’s more, this apparently complicated problem has some working solutions.
This stop error stems from a flaw in the boot state due to device drivers and data corruption. Sometimes it could also be a result of hardware failure or a virus. Without exception, you will get this stop 0x0000007B error on the Blue Screen of Death or Stop Error.
Even when Windows recovers from the problem, you still get a prompt that says “Windows has recovered from an unexpected shutdown” and this problem can happen on any version of Windows. If this is your problem too, here are some solutions.
Just restart the device to see if the problem solves itself. Sometimes it does and never reappears again. Eles, read on.
1] Make changes to the Hard Drive Controller
If you recently make changes to your hard drive controller, this could be the reason, so reverse the situation by undoing these changes. You carry out any of the following procedures :
- Use System Restore.
- Reconfigure the new hard drive controller.
- Remove the new hard drive controller if reconfiguring doesn’t work and you don’t essentially require it.
- Start up with the Last Known Good Configuration in order to undo registry and avoid the impact of driver changes.
- Go back to the version of hard drive controller and device drivers you had before the driver update.
All these may or may not solve the problem depending on what caused it. If this solution doesn’t work, at least you’ll know your hard drive controller isn’t the problem.
2] Verify SCSI chain termination
If you are using SCSI hard drives, faulty termination is likely the cause of the error. So you need to cater to this problem in order to solve it. However, home computers usually use PATA and SATA and not SCSI, so this might not be your problem, to begin with.
3] Verify installation
Make sure the hard drive is installed correctly. If you haven’t installed any new drive recently, the problem could be something else.
4] Verify BIOS configuration
You need to make sure that your hard drive is correctly configured in the BIOS. Change settings as needed to ensure proper configuration.
5] Scan for virus
As mentioned earlier, the stop error can be a result of a virus. So you need to scan for virus and mainly check the boot sector and MBR for malware attacks. If this is the problem, follow the usual routine of antivirus software assistance and restart your device. Always keep your antivirus updated in order to prevent this problem from happening at all.
6] Update drivers
Outdated hard drive controller drivers can cause this error, so update the device drivers.
7] Change mode in BIOS
Some advanced SATA features can cause this error. Change the SATA (AHCI) mode to IDE mode (ATA or Compatibility Mode) to undo the error and avoid it in the future. In some older versions, the solution might be just the other way around. Clearing the CMOS can also help.
8] Run chkdsk
If the boot volume is corrupted, running chkdsk on the hard drive will solve the problem. You might have to run chkdsk from the Recovery console.
9] Hard drive errors
If a hard drive has gone bad, you will need to replace it. There is no way out from a damaged hard drive.
In order to avoid the error from occurring again, configure the patching infrastructure so that CU and delta updates are not simultaneously installed during a single reboot.
