I recently bought a 240gb SSD and downloaded a win7 iso from Microsoft to install it. Currently I'm running off my 1tb HDD, and I don't have a dvd handy to burn it to, so I mounted it with daemon tools lite and installed it to the SSD.
Now when I load the HDD, I get two Win7's to choose to boot from, with one being the one on the SSD. When I try to boot from the SSD, it gives me the
Bootmgr is missing, press ctrl-alt-delete to restart error. I tried one reinstall, which fixed nothing, and restarting fixed nothing, so I'm running out of ideas. Only other thing I've seen so far is another format/wipe of the SSD and reinstall clean again.
I also tried putting the iso on a usb, it installed as it did when mounting with daemon tools, and still no bootmgr. There are also still two OS's on the HDD. I think I'll try with the HDD disconnected next and see where that lands me.
