I have XP on one internal hard drive and the Vista Beta RC-2 on another. I installed Acronis Disk Director Suite 10 in Vista yesterday and then installed their Boot Manager from that suite to enable double booting. It did not find Vista, but booted into XP as the only choice. Today I turned on the computer so I could remove the program from Vista, but the computer will now not bootup at all. I see: "Acronis Loader: No configuration file present. Press <Enter> to reboot." When I do that it does not reboot but repeats the above message. I cannot get into Safe Mode because Acronis has blocked the function of the F8 key where that menu is available. I can boot from a bootable CD, but I don't have a Windows boot disc except XP Pro Setup disc. In short, Acronis Loader has brought my system to a complete halt. I will appreciate any suggestions for a solution to this serious problem.
