Precautions: Recover Data When WHEA Uncorrectable Error Occurs

If you see WHEA_UNCORRECTABLE_ERROR, it indicates a hardware error. You probably need to reinstall or fresh install Windows 10. In most cases, system reinstallation will cause data loss. Thus, you are advised to recover data from your computer even it fails to boot. EaseUS bootable data recovery software is my recommendation. It enables you to boot into your system with a WinPE bootable disk when you are faced with Windows 10 WHEA uncorrectable error.

Rescue your essential files with the step-by-step guide now:

Step 1. Create a bootable disk

Prepare an empty USB. If you have important data on it, copy the data to another device. When you create a bootable disk, the data on the USB will be erased. EaseUS Data Recovery Wizard WinPE Edition will help you create a bootable disk.

Connect the USB drive to PC, launch EaseUS Data Recovery Wizard WinPE Edition. Select the USB drive and click "Create" to create a bootable disk.

Step 2. Boot from the bootable USB

Connect the bootable disk to PC that won't boot and change your computer boot sequence in BIOS. For most users, it works well when they restart their computer and press F2 at the same time to enter BIOS.

Set to boot the PC from "Removable Devices" (bootable USB disk) or "CD-ROM Drive" (bootable CD/DVD) beyond Hard Drive. Press "F10" to save and exit.

Step 3. Recover data from a hard drive that won't boot

When you boot from the USB, you can run EaseUS Data Recovery Wizard from the WinPE bootable disk. Select the drive you want to scan to find all your lost files. 

Click "Scan" to start the scanning process.

Recover data from the computer or laptop. After the scan completed, you can preview all recoverable files, select the targeted files, and click the "Recover" button to restore your files. You'd better save all of the recovered data to another place to avoid data overwriting.

Fix 1. Reset and Install Memory/RAM (Manual Fix) 

Reseating the memory is the process of removing the memory module from their DIMM slots and correctly placing them back into place. This is usually the first step of diagnosing and potentially solving a number of common problems like green screen, blue screen, an abnormal amount of time booting, and more. Follow the steps to reseat and install Memory.

Step 1. Locate the side panel latch or thumb screws for some models

Step 2. Pull latch releasing the side panel, remove the side panel, and set aside.

Step 3. Locate Memory. Gently release the clips that hold the RAM in place (one on each side) do this for all available memory modules.

Step 4. Carefully replace each memory module into the DIMM slots located on the motherboard.

Step 5. Press firmly on each side of the memory module until the retaining clips click back into place.

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

Fix 2. Fix MBR and System File Error

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:

• Bootrec.exe/fixmbr
• Bootrec.exe/fixboot
• Bootrec.exe/rebuildbcd

Step 5. When it completes, exit the Command Prompt window, eject the DVD, and restart the computer.

Fix 3. Fix BCD Error

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.

Fix 4. Troubleshoot Driver Issue

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.

Fix 5. Repair the Error with Installation Disc

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.
