I had Windows 7 and Windows 8 in dual boot mode on one drive in two partitions. My motherboard crashed and ended up getting a new motherboard with a new chipset. I couldn't get it to Windows 7 to load on the new motherboard so I reinstalled Win 7 on the primary partition. But now I don't see the option to dual boot. Short of reinstalling Win 8 as well on the secondary partition, not sure how to resolve this. Thanks.
