  • Once at the installation screen, press SHIFT + F10 to open the Command Prompt.
  • Type diskpart and hit Enter.
  • Next, type list disk to view all connected disks.
  • Identify disks labeled as foreign ; these are the dynamic disks needing conversion.
  • Use select disk X, replacing X with the disk number you noted.
  • Finally, execute convert basic to change the disk type.

If there are multiple foreign disks, repeat these steps accordingly for each. Close the Command Prompt after finishing and reboot your PC.

If successful, converting from dynamic to basic should eliminate the error 0x80042444 – 0x4002F, allowing the installation wizard to recognize your disk and proceed with the Windows 11 installation.
