Okay, I don't think this is going to solve without a re-install of VISTA. I changed things and now bcd file and the OS are on the same partion (2). That got rid of the memtest error. I think we have come to the end of the line. At least I got bootmgr to run. No idea why VISTA cannot now boot. I seem to have lost the recovery option (Alt + F10). ACER sell recovery disks, but I seem to have a serial number not recognised, so I probably will not be able to get a recovery disk. I may need to rely on someone local with an ACER disk.
