Greetings all. Having some issues getting Windows 7 installed and working on Boot Camp on my riMac (just bought new). I will run thought what I've done leading up to this but the current issue is that I've run into "no bootable device -- insert boot disk and press any key" black screen. I found a way past it by holding down ALT when rebooting but I'm presented now with a black sceen and 2 pictures of "Macintosh HD" disk drivers and not sure where to go from here. Process thus far : - Have in my possession an activated Win 7 Ultimate 64-bit disk which works fine on my other PC. - Made an iso of the disk and put it on desktop on Mac. - Formatted my USB stick. - Went into BCA (Boot Camp Assistant), checked all 3 boxes (install Windows, get installation files, make bootable device etc) and selected my USB stick to make as the bootable drive. That didn't work as it said I needed a 64-bit version of Windows. So I went through all this http://forums.macrumors.com/showthread.php?t=1561855 and finally got it working. - BCA then started running, copying the Windows files, then installing them etc and eventually got to the partitioning screen. I moved the slider to give 500 GB for Windows which left around the same for Mac. Set it going and after doing its stuff it rebooted the machine and I got a black screen for a short while until "no bootable device, press any key to continue". The bootable USB stick was still in at this point. Despite having a wired keyboard it wasn't responding and nor was the mouse (wireless). - Hard reset the machine by holding power for 5 seconds and tried holding ALT instead. That brought me to a black screen too, but now "no bootable device -- insert boot disk and press any key". Not sure what I did but got to another screen with 2x pics of HDDs both called Macintosh HD and a drop down menu for wireless I think it was (could be wrong). I selected the right hand drive and it's booted back into Mac. Not sure where I go from here. I tried running BCA again, but the bottom option now says "remove windows 7 or later version" and when clicked says "the windows partition and all of its contents will be lost" so it would appear I do have a Windows partition now. In Disk Utility it shows : Macintosh HD (621.33GB Core Storage Logical Volume Group) - Macintosh HD (Start up disk: Macintosh HD) - BOOTCAMP (Mounted partition: Boot Camp) USB MEMORY BAR Media In the partition tab of the top Macintosh HD one it says Partition Layout: Current and shows Macintosh HD Size 500.35 GB in Mac OS Extended format and underneath it shows BOOTCAMP Size 499 GB in MS-DOS (FAT) format. Where has Windows gone and what do I do now? Seem to have come to a dead end here as I don't know what I've done wrong. Thank you. PS. I do not have an optical drive, hence why it was done from USB stick.
