don't worry here the solution.....i have gone to many site to know how to install fedora 7 with vista (Ultimate).....but i didn't get proper answer but at last i have found it myself... what i did is ( i dunno is this the procedure or not)
I Installed Vista fresh in my hard disk.....after booting in it...when to disk management and made 40GB Free (i.e deleted the partition) after that installed Fedora 7.....
while you are in choosing the partition where to install Fedora you have to choose "
Use free space on the selected drive and create custom layout" thats it.....
(Before i made mistake here only.....i just left 10 GB free because in many site many said only 10 GB is enough)
now when Fedora completed...you just log in to it......
Now restart the machine....you will b give 10 seconds to choose the boot option thats is windows r fedora....if you click enter within 10 seconds you have option.. to boot in vista...
if you don't want to do this and you want vista to be automatically booted n in option fedora...than you have install EasyBCD by Neosmart Technologies and configure it. thats it
It worked for me.....sorry working for me....
