How to Solve the 0x8004242d Error?

Solution 1: Change a Dynamic Disk to Basic Disk

Step 1: Press Win + R to open the Run box.

Step 2: Type diskmgmt.msc and then click on the OK button.

Step 3: Disk Management will show if disks are dynamic or basic in the Type Column. Right-click on every dynamic disk drive and then select Delete Volume.

Step 4: Right-click on the hard disk and then select Convert to GPT Disk.

Step 5: Check whether the error persists.

Solution 2: Delete All Partitions

When the computer is afflicted with some kind of corruption in the Master Boot Record, users are most likely to encounter the 0x8004242d error. The symptom of it is either the missing of the drive that Windows needs or a corrupted drive.

It’s reported that several users facing the problems fixed the issue by booting from a compatible media and deleting every partition before formatting them.

Although the efficacy of the solution has been proved, it usually entails irrevocable data loss. For users who fully intend to do a complete clean, It doesn’t matter what could happen to the data on the drive. But for users who don’t want to delete every partition of it, that doesn’t serve them well.

Backup Your Data

Hence, if you want to backup your data on the drive safely before deleting all partitions, you could use the instructions listed below that tell you how to create a system image backup.

Step 1: Type in Control Panel in the search bar and then open it.

Step 2: Browse Control Panel items by category and then navigate to System and Security > File History > System Image Backup (at the bottom of the left pane)

Backup Your Data

Note: Step 2 is applicable to Windows 8, 8.1, or 10. If you are using Windows 7. Navigate to Backup and Restore.

Step 3: Click on Set up backup.

Important: After the computer has finished searching for suitable backup devices, it will ask you to determine where you want to save the backup. Keep in mind that saving a system image of the computer in a network location is not recommended on account of the unreliability of networks. If you want to save the system image to a partition of an SSD/HDD, ensure that the SSD/HDD you are going to use will not be contained in the system image itself. Given those considerations, the perfect choice is to store the system image on an external storage device.

Step 4: Select the disk drive where the system image will be saved, and then click on Next.

Step 5: Select the drives that you want to save into the system image, and then click on Next.

Step 6: The utility will present a clear picture of general aspects related to the system image, such as the location to which the system image will be stored, the drives to be backed up, and the disk drive this system image will occupy. Check those details and then click on Start backup.

Step 7: Wait for the system to create a system image. Based on the size of the disk drives you want to backup, this process may take a considerable amount of time.

Note: After the system image is successfully created, you will be able to find it by following this path:
X:\WindowsImageBackup\(the name of your computer)\Backup YYYY-MM-DD HHMMSS
X stands for the drive letter of the disk drive where you store the system image. YYYY-MM-DD HHMMSS stands for the exact time when the system image was created.

Delete All Partitions

After you have successfully backed up important data, you can use the following steps to delete every partition to fix the 0x8004242d error.

Step 1: Insert an installation media and reboot your computer. After seeing the initial starting screen, your computer will prompt a message asking you whether you want to start the computer from the installation media. To confirm this, press any key.

Step 2: After you have managed to boot your computer from the installation media, click Install now, and follow the installation steps.

Step 3: A second message will be brought up asking you to choose the type of installation you want. Select Custom: Install Windows only (advanced).

Solution 4: Disable USB Boot Support

On top of the possible causes covered above, there is another potential culprit that could wind up triggering the 0x8004242d error, which is the conflict between the new counterpart (UEFI) and the legacy setup (BIOS). Many users have found that if a computer includes both features, with the UEFI Boot Support enabled, it could well lead to the 0x8004242d error.

In this case, to fix the issue, you should reboot your computer and disable the UEFI Boot Support by entering the BIOS Configuration. This is also a time-tested solution. Refer to the following steps to learn how to do so:

Step 1: Reboot your computer and press the Setup key right after the initial startup key has come up. Keep pressing the key until you enter the BIOS menu.

Note: In most cases, the Setup key is one of the F keys (F10, F8, F6, F4, and F2) or the Del key. If none of them works on your computer, search online for the specific steps needed to enter the BIOS settings of your computer.

Step 2: Once you have entered the BIOS Configuration, switch to the BOOT tab and make sure that the UEFI Boot Support option is Disabled.

Step 3: After this modification has finished, confirm, and save the modifications. To check whether the issue has been resolved, reboot your computer and repeat again the action that previously caused the 0x8004242d error.
