Did you encounter the following error during the Windows Server 2008 R2 upgrading?
“Please reconfigure your boot.wim file to use the flag of 9 settings for the first image, and restart your installation. Error code: 0x8030002F”
If so, I am afraid that you are using a corrupt installation media. Where did you obtain he installation media? Please use an official media to begin the upgrading.
