I have a trusted old W7 and a brand new W10 on two different SSDs that when connected one at a time, worked perfectly. After installing EasyBCD on W10 drive, I hooked up both SSDs, launched EasyBCD, tried to find my W7 drive and couldn’t. W10 disk management saw the W7 drive as present but unavailable due to a conflict. I tried to locate it thru EasyBCD but no luck. I installed part of EasyBCD to create a USB bootable thumb drive on my visible drive, thinking it might make it visible to the other drive. Upon reboot with both SSDs attached, neither OS will boot. I disconnected the W10 drive, thinking W7 should boot as before. No joy. I now have 2 drives with previously working OS’s that even Windows repair utility can’t recover. I have a restore point on the W10 drive that now I can’t access. I also have a complete image backup of W7 that now is inaccessible. Where do I start to undo this disaster? EasyRE? I really don’t want to rebuild from scratch.
