Recapping my previous threads, I had a problem with BCD not showing the BIOS option of the two separate drives (one with XP and the other with W7) after having got rid of the "System check" virus. I updated from 1.7 to 2.1 and the problem was still there....from cold no option screen but on restart the option screen appeared. I then did a reset of the configuration and was very carefull to ensure I added the new entries prior to restarting. Now I've lost it all. I can't get into either drive. Startup and I get a msg. saying Invalid boot.ini Using F8 and getting the boot options if I select the W7 drive I get a msg. saying ntdlr missing. I have used the XP disk to try and do a repair but without success. I have entered the activation code but every time I try I get the msg. saying that I need to activate before I can log on. When I try to activate the computer just stays on the desktop screen. I've tried unplugging the W7 drive leaving just the one with XP but no go. One further odd thing.....Originally the XP drive was designated as the "H" drive whilst the W7 drive once added was designated as the "C" drive. On the 1.7 version of Easy BCD the XP drive was shown as the "D" drive (no mention of "H"). and that was the case when automatically transferred over onto the 2.1 version. After the reset the XP drive was shown as the "C" and the W7 was shown as the "D"! What else can I try?
