Boot Camp crash on iMac 27' 2011

[spasmsouns]

Hi everyone! Sorry for my english, please.
I need your help. I have problem with boot up in the windows from my iMac 27" 2011.
I used Boot Camp Assistant to partitioning drive, and after automatically reboot, i have just white screen.
My CD-ROM is ok, i tried to boot in windows install with Start up Manager (Option hold), but it's just stuck.
I tried to install Windows with WinClone. Same. I tried to swap hard drive, it did not work.
I tried to reset NVRAM, SMC, it did not work. Please, help me

You're going to need to provide more information so someone can answer. Which version of macOS are you running and what version of Windows are you trying to install? And what do you mean "tried to swap hard drive"? If you could provide a screen shot taken while in Disk Utility showing the partitions, it might help us to see what's going on.
