Hello guys! I recently acquired a Mac Pro 4,1 for which I made some upgrades - a USB 3 card and a PCIe 250gb SSD which has El Capitan installed. I was looking to install Windows 10 on the SSD and dual boot between OS X and Windows: here's what I did I heard bootable USB drives don't work so I made a DVD image of Windows 10 I partitioned my SSD with FAT32 and labeled it Boot Camp Restarted while holding ALT/option and running the DVD installer Formatted my BOOTCAMP partition to NTFS I now get this error message "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu." Any ideas? Should I try installing Windows 7 and then upgrading to 10?
