I've got XP home and Vista RC2 installed at the moment on separate hard disks. A few weeks ago I did a format and reinstall of XP on my main drive. After the format, the boot screen where you can choose to boot to either Vista or XP disappeared. I tried to get into Vista today by going into the boot menu of my motherbord and choosing to boot from my second hard disk. It wouldn't boot though, I just got a message saying "invalid boot disk". Does anyone know what's gone wrong with the Vista installation and if there's any way I can get it working again without reinstalling?
Thanks in advance
