I had a setup where I had 7 x64 & & x32 on SSD and upgraded 10 x64 on HDD. The triple-boot worked fine & when I removed x32 from boot menu, the 2 remaining OS worked fine. I've since deleted x32 partition and moved 10 to its partition on SSD and 10 will not boot. I've tried a repair with USB but it doesn't work like 7 and results have been few. At least now I get a boot screen and the spinning dots.........then the screen goes dark (not black) and the cursor arrow moves with the mouse. I've tried everything I can think of including EasyBCD, cmd to repair boot, repair tools on boot. Can anyone help where 7 installation isn't jeoparised as it still works.
