Reinstalling Windows 7 on 7/10 dual boot breaks dual boot
I installed the 10 tech preview along side my win 7 ultimate, I reinstalled, the Windows 7 side of the HDD because after however many years the OS had a LOT of clutter, and even though windows update was a nightmare I finally got all the updates installed and only the necessary drivers/software installed for the upgrade. However reinstalling 7 ruined my dual boot, I can no longer boot into the 10 tech preview... I was on build 10166, and I only have an ISO of 10162 which fails on startup repair... need suggestions on how to fix the bootloader to see both OS!
