i tried to make muti boot system with vista pre installed, because i needed xp to play games that doesnt work in vista, like company of heros opposing front. i divided up my partition (300GB into 50GB, and 20GB, 10GB for recovery) obviously, vista was installed in 250GB, i divided it by going into disk manager. i reboot it one time, and put the xp cd in. so i finished installing xp but when itself rebooted, it says HDD read err. so i reformay the whole thing, deleted partitions, except for the recovery. now installed xp first, and restart the pc, booting from vista cd. and i installed it. i turned it off, and turn it back on, and there is a menu asking me to choose recovery or vista to boot. there is no xp. what i think is that at first xp was installed in C 50GB but when i installed vista that partition was changed to H. anybody know the solution for this?
