Why won't my Mac Mini with boot camp Windows 7 boot if I plug in a thunderbolt disk drive
OWC Brittany C: there is a limitation on using a Thunderbolt device and Windows 7. Having a Thunderbolt device plugged in when trying to boot to Windows 7 will prevent boot. Also the machine will not detect a Thunderbolt device in Windows 7 unless it is plugged in upon start up. So basically thunderbolt devices are not going to work in Windows 7. You would need another operating system on that machine in order to boot with the device plugged-in when using Thunderbolt. Or Windows 8. They fixed the Thunderbolt bug in the Windows 8.
