The two OS are in 2 disks.
When each OS was installing, the other disk was offline.
I boot from different disk by modify CMOS's config.
Now I'm trying to select the OS by the booting menu.
First, I modified the boot.ini, add a commandline and set rdisk=1, but I failed.
Now, I'm trying to do it by EasyBCD.
Good luck to me...I'd tried it since 2 days before.
