Bootcamp will not install on my late 2012 mini Samsung EVO 840 1tb SSD
I recently replaced my 256gb OWC SSD in my late 2012 Mac Mini with a Samsung EVO 840 1tb.
I did the following
1) Using 10.9 recovery i initialized and created a single clean partition on the 1Tb SSD
2) I installed a clean copy of 10.9
3) Using migration assistant i transferred apps and documents from my previous SSD via a USB 3.0 adapter to the new SSD
4) Using Bootcamp Assistant 5 I created an ISO version of a clean copy of Windows 7 Home Premium and downloaded the Apple updated Boot Camp drivers to the same 16gb Sandisk Extreme USB 3.0 thumb drive
5) Using Bootcamp Assistant created a 199gb Bootcamp partition on the new Samsung SSD which appeared to go to completion
6) Mini restarted from the Bootcamp USB drive and Windows started successfully
7) I chose Windows 7 Home Premium install
8) I got the "which partition do you want to use to install Windows" screen, chose the Bootcamp partition, using the advanced option I chose format which appeared to complete, hit NEXT and then got an error that windows could not install because it could not find the NTFS partition, and then i was stuck.
When I rebooted I first got the Unable to find a bootable disk, hit any key error. I then physically shut down the computer, held down the alt key chose the Mac partition and the computer successfully booted. I could see the Bootcamp partition and according to Disk Utilities, the partition was formatted as NTFS.
The only connections to the Mini were a 30" Apple Cinema via a Apple Mini display connector, the keyboard and mouse via USB, and the USB Bootcamp Created 16gb Sandisk Extreme USB 3.0 thumb drive. I also have an internal Apple 1 tb hard drive with no applications installed. In the apps installed on the Samsung does include Parallels 9.
What have i done wrong or missed? IF nothing it appears that the Bootcamp assistant supplied with 10.9 may have an issue with my Hardware setup including the Samsung EVO840 1tb drive.
