Failed to Format the Selected Partition 0x80070057

Error 0x80070057 during Windows setup usually means Setup cannot format the selected partition because of partition table problems, disk errors, damaged installation media, or an incorrect target disk.

Before You Clean the Disk

• Make sure you selected the correct disk and partition.
• Back up or recover files if the disk contains important data.
• Disconnect extra drives to avoid formatting the wrong disk.
• Use reliable Windows installation media.

Fix the Error in Windows Setup

1. Restart Windows Setup and choose Custom install.
2. Delete only the target Windows partitions if your data is backed up.
3. If format still fails, press Shift + F10 to open Command Prompt.
4. Run DiskPart commands carefully: list disk, select disk X, then clean only when you are sure the disk can be erased.
5. Close Command Prompt, refresh the setup window, and create a new partition.

Recover Files with Qiling Deep Data Recovery Before Cleaning the Disk

If the disk has data you still need, do not use DiskPart clean yet. Recover files first with Qiling Deep Data Recovery from another Windows PC.

Step 4. Save recovered files to another disk. Clean or recreate the partition only after the data is safe.

Conclusion
