iMac 27" shutting down during Windows 7 install I've got a problem with my Mid-2010 iMac 27" where when trying to Bootcamp Windows 7 x64 (Ultimate edition) it simply wont get past the expanding files stage.

Despite numerous attempts to use USB and the retail DVD, it will take about a second to copy the files and then will start to expand files.

After a few minutes of hearing the DVD drive spinning, it shuts down.

Has anyone ever encountered this?

I'm currently downloading the latest ISO from MSDN to try however I'm not holding my breath lol.

Look forward to hearing from you all :)

Thanks

Gavin
