I mistakenly did as per the thread title. The ssd on it's own won't boot without windows boot manager which has an entry for w7 and w7 home premium, w7 being the install on the ssd and, I presume, home premuim being the old w7 install on the hdd. I could remove this via msconfig but not sure if I should (yet). If I plug the hdd in it goes straight to the mbr on the hdd, launching grub and offering linux or w7 - the drive was my old os one which will now be just storage once things are up and running. My question is will FixBoot or FixMbr with just the ssd plugged in make the ssd bootable, when the hdd is plugged back in or am I better off reinstalling w7 to the ssd, doing it properly. I'm assuming, of course, that the ssd doesn't have an mbr as it picked up the one off my hdd? thanks.
