how can i boot from other windows

i had windows 7 and i install windows 8 also

i was choose from the both and they was good ..

but i install windows 7 again in c:/ and it's working but i cant choose from it and windows 8

so windows 8 is disappeared but it's already in e:/ but i can't go to it

my laptop go to windows 7 directly

notes
system configryation have windows 7 only

You can also install EasyBCD (click Download - no Name or Email required) to add Win8.

thank u :)gregrocker , Ztruker :)
the best way to solve this problem is using EasyBCD and then u must repair your old windows
