When upgrading Windows using ISO media you encounter an error code 0XC1900211 & 0XC1900212 which says The system does not pass the disk space, it means that you do not have enough disk space for ISO media to extract files on the computer. All the ISO files are unpacked during the upgrade process, and if they do not have enough space, it will fail.


0XC1900211: MOSETUP_E_DOWNLOAD_UNPACK_DISKSPACE_BLOCK
The system does not pass the disk space requirements to download and unpack media.

0XC1900212: MOSETUP_E_DOWNLOAD_UNPACK_DISKSPACE_MULTIARCH_BLOC K

To resolve this make sure your hard disk has enough space on your computer before kicking the upgrade process.
