Q: Bootcamp - No bootable device??? iMac Mid 2010 21.5"
hey!
so i have been trying to install windows 7 on my Mid 2010 21.5" iMac 3.06Ghz i3.
I have had a few errors through the night, firstly with there being no usb install button in bootcamp, so with a lot of research i finally 'recoded' the .plist file so that my mac and id etc etc were in the accepted file list. so i got windows 7 successfully put onto the usb i wish to use, and then went about trying to partition my hard drive, which was a pain as well because i had to fix the 'disk could not be partitioned error'... but i prevailed and i finally got it partitioned. And now we come to my issue. whenever the partition is done it goes into the presumed boot for windows, but up comes a black screen with text on it, presumably a CLI. It reads ' No bootable device' ...... I have tried the recommended troubleshooting i have seen from other posts here, with people recommending using disk utility and verifying and repairing the hard drive, a simple restart etc. Another thing that is odd about this is that whenever i go into the disk utility it says that there is a partitioned part of the hard drive named bootcamp, which is to be expected, but whenever i launch my iMac, holding down the options key there are only two options, Macintosh HD and a recovery of the Macintosh HD. I find this odd how disk utility can realise there is a partitioned hard drive for bootcamp but yet the boot files are not.
I have tried a lot of things, so please please don't just refer me to the things i mentioned above with me trying to fix it.
I have seen some people getting their problems fixed by showing a terminal command, and giving the information out and letting some people decipher it, so if you need anything like that or additional information please feel free to ask. This bootcamp windows partition is very high priority as i will be needing it for my school coursework, so i would find it extremely helpful if i could get an informative reply.
Thanks very much, Mark
