You can learn these things in this video before you try Fix 2, Fix 3, or Fix 4:
- Fix MBR and system file
- Fix BCD error
- Fix driver issue
If Fix 1 fails, you can repair MBR or system file to fix the WHEA_uncorrectable_error. Since you cannot boot your system, you need to start the computer with the Windows 11/10/8/7 installation DVD. If you don't have one at hand, you need to create one with Windows Media Creation Tool. Then, follow the steps to fix the MBR in Windows 10 with CMD.
Step 1. Boot from the original installation DVD (or the recovery USB)
Step 2. At the Welcome screen, click "Repair your computer" on the lower-left corner.
Step 3. Choose Troubleshoot > Advanced Options > Command Prompt
Step 4. When the Command Prompt loads, type the following commands and press Enter after each:
Step 5. When it completes, exit the Command Prompt window, eject the DVD, and restart the computer.
You can also fix the BCD error to solve your WHEA uncorrectable error. Enter Command Prompt as mentioned in Fix 2, and follow the steps below.
Step 1. Type each command line and hit Enter each time:
- ren BCD BCD.old
- bcdboot C:\Windows /1 en-us /s G: /f ALL
Note: c:\ is the drive where Windows 11/10/8.1/8 is installed on.
Step 2. Type exit in Command Prompt when the process completes and then restart your PC.
Corrupt, damaged, or outdated device drivers can also lead to various blue screen errors. And WHEA_UNCORRECTABLE_ERROR is no exception. Thus, you can check your drivers to solve this problem.
Step 1. Reboot your PC, press F8, or shift + F8 to Enter Safe Mode. Ask your manufacturer for the exact key if neither works.
Step 2. Click "Troubleshoot > Advanced Options > Startup Settings > Restart".
Step 3. In Safe Mode, press Windows key + R, type devmgmt.msc, and press the Enter button to open Device Manager.
Step 4. If there's any yellow or red sign on any device, update it. After that, restart and see if WHEA uncorrectable error still exists.
If your computer still fails to boot when you receive the error, you should create a Windows 11/10/8/7 repair disc and repair your system error. To create a repair disc, you need a healthy and bootable PC.
Step 1. Insert CD/DVD into DVD-ROM or connected external DVD drive.
Step 2. Click "Control Panel" on the computer screen, then click "Backup and Restore (Windows 7)".
Step 3. Click "Create a system repair disc" from the left column to open the repair disc creation window. Follow the on-screen instructions to create a system repair disc.
Step 4. Connect the disc to the PC with WHEA_uncorrectable_error and restart to boot from the DVD. You may have to change the boot settings in your BIOS if booting from a CD/DVD is not enabled.
Step 5. On the "Install Windows" screen, make the appropriate selections for language, time, and keyboard, and then click "Next".
Step 6. On the next screen, click "Repair Your Computer". Do not click "Install now". Then, click "Next", and select "Startup Repair" or whichever option you wish to apply.
After the steps, you can boot to your computer as usual. Then, check if you have solved the WHEA error. If the error still exists, you can restore the system with the repair disc. As I have mentioned in Step 6, you have many options. If you still have the error, select "System Restore" and follow the on-screen steps.
System Restore: Restore the Windows system to an earlier point in time. Choose this option if Windows 11/10/8/7 starts, but something has changed since a recent installation or update. You'll pick a restore point based on the date and time (start with the most recent). You may lose recent program changes, but not your data.
It is frustrating if any one of us encounters the WHEA uncorrectable error or other blue screen or green screen error.
