Instaling Win7Pro on imac

[SC92]

We have 25 student imacs and I have been attempting to use bootcamp to install Windows 7 Pro on another partition. Windows 7 looks like it installs ok, although when trying to boot up into it I just get the flashing _ icon in the top left corner. The newly "installed" Windows partition isn't recognised when holding the cmd key on startup but is recognised by osx on the startup disk preference in system preferences.

 

Any help greatly appreciated.

 

Cheers.

Had a similar thing but just on some netbooks I was imaging, image worked fine but just got flashing cursor, turned out I need to change the flag on the partition to make it a boot one, restarted and it was fine afterwards. (did have an isse with creating partitions to image to, used Gparted and the version was forcing me to have a 1mb space at the start, could not get around that and that stopped it booting. Used an earlier version of Gparted and that was fine).
