Hello everyone! I replaced the HDD in my late-2012 iMac 27-inch (1TB Fusion drive) with a 512GB Samsung 830 SSD. Before replacing the HDD, I had split the fusion drive and installed Windows 8 on the 128GB Apple SSD. After the replacement, the Windows drive will not boot, so I reformatted it. I am able to see both drives in disk utility. I installed ML on the Samsung SSD, and ran Bootcamp. However, the Windows installer is not able to install on the 128 GB SSD, the error being that it is not a bootable drive and to change it in the BIOS. Any help/advise is greatly appreciated. My plan is to have Windows 8 on the 128GB Apple SSD and ML on the 512GB Samsung 830. Thanks!
