Fix: error 0x8004242d failed to format the selected partition in Windows 11

Error code 0x8004242d appears when formatting an existing system partition on a fresh install of Windows 11 from a USB flash drive. Error 0x8004242d may be because the system partitions were converted to a dynamic type, but a basic one is needed. This could be a damaged partition structure or a mismatch with the MBR, where the bootloader file could be damaged.

How to fix error 0x8004242d when formatting a partition in Windows 11?

First of all, click “Delete” on the formatting error section. Next, create a new partition from the unallocated space. If the delete button is not clickable, we will analyze below the methods for fixing the error 0x8004242d when formatting a partition.

Solution 1: When you are in the disk layout when installing Windows 11 from a USB flash drive, press Shift + F10 or laptops Fn + Shift + F10 to bring up the command line.

At the command prompt, enter the below commands to fix disk errors.

Solution 2: If fixing errors on the disk did not help (Solution 1), then erase the disk completely. You must create a copy of all the files you need on disk. Do not confuse it with a partition, as the method below will erase the entire disk, not the partition, and you will lose all data on the disk.

Open CMD, as described in Solution 1 and enter the commands, then click on update in the Windows setup program (two round arrows).

diskpart - launching the tool for working with disks.
list disk - display a list of disks.
sel disk 3- select the disk on which the partition gives an error.
clean all - clear the selected disk.
exit - exit from the tool.
