Can't Install, Error code: 0x8030002F

Hi, tried to install my new Windows 7 on my PC here today but instead got the message:

Windows was unable to create a required installation folder.
Please reconfigure your boot.wim file to use the flag of 9 settings for the first image, and restart your installation.

Error code: 0x8030002F

Someone who knows what I can do, perhaps. have had the same problem?

Thanks in advance

PS. Is Windows Vista Ultimate on it now.

Do you get this message when trying to upgrade or clean install? If it's while your upgrading try changing your boot order to cd first and do a clean install.

I tried to format my laptop but Windows was unable to create a required installation folder.

Please reconfigure your boot.wim file to use the flag of 9 settings for the first image, and restart your installation.

I am using a Toshiba sattelite. The original operating system was windows professional but i changed it to windows ultimate. Now i am having to many problems with this OS that is why i want to put it back to its original OS but this error keeps popping out.

I also tried the boot thing but it didn't work.

What should i do?
