IS this the "remove media" missing message?? i.e. Setup starts, then restarts your PC but doesn't recognise it's the second go and goes back to the beginning...ad nauseam. On first restart remove media!
Aha - I see now - could be fun re-jigging the inside of the PC but I'll wait a little (howling gale here and power goes on & off a lot. Don't trust the UPSs to run long enough to complete operations!).
Win 7 is on the SSD Disk 1. I have a second SSD (not installed) to take the Win 8 I've got already up and running.
I don't need to "install" anything.
Do you mean switch cables around? Change things in the BIOS?
