Windows 10 upgrade : Error 0x8004242d?

Answer 1

You could try using the following solution:

Change a dynamic disk to a basic disk

Because Windows operating systems cannot be installed on a dynamic disk, it would prompt an error if you tried to format the partition to install. Before you use the following steps, remember to back up the dynamic disk to be converted to basic.

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.

When you are in the process of fixing the 0x8004242d error, if any issue related to data loss happens, you can certainly use Bitwar Data Recovery, a powerful and user-friendly data recovery tool, to bring back data that has been unintentionally deleted.

Step 1: Download Bitwar Data Recovery from our official website and install it.

Step 2: Open the program and choose the disk drive where the missing data were stored and then click Next.

Step 3: Choose a scan mode in this stage. We would like to recommend Quick Scan, which is capable of recovering a healthy number of lost files. If it doesn't work, you can run the software again and use Deep scan, which is more effective.

Step 4: Choose the types of files you want to recover and click Next.

Step 5: Preview the desired files to check their intactness. Select those files and click on Recover to start the recovery process.
