Hi all,

Long time browser of the Mac Rumours forums and found the information at this site useful when I bought my first iMac in September of last year (2010). Eventually decide to sign up as I would like to tap some of the knowledge here at this forum, so I hope its ok that I jump in at the deep end.

I am experiencing persistent problems at boot-up before any OS boots on a Summer 2010 iMac Core i3 4GB RAM 1TB HD ATI 5670. I have a dual boot system, Snow Leopard and Windows 7. By default I have bootcamp configured to boot automatically to Windows 7.

My problem starts when I first boot: I get the bright screen and the chime, and thats it, its sticks there on the bright screen and progresses no further - no disk activity nothing. The only thing I can do is cold shut-down the system. There is a way around this, I can press the Option key to bring up the "Select OS" screen and can select my OS of choice, its then proceeds to boot just fine. I have had it when I get the "Select OS" screen and I cannot select the OS, again I have to cold shut-down the coimputer and try again. It is worth mentioning that once running in a particular OS it works just fine, and I typically just sleep the system from day to day.

Any ideas of what the problem is and how I can fix it?

Thanks for any comments in advance.
