Urgent...Help for dual boot windows...URGENT...

hi
i need an urgent help regarding dual booting.but just for some info,i want to tell u that i have windows vista ultimate x64 and windows 7 ultimate x64.Both are retail version,to which i apply crack to activate it.which works.
this is the case in single OS installation.
but i want to install both OS in my laptop.i have dell studio 1737.

i want to install win7 as primary and basic os and vista as secondary os.i have tried doing it,by installing win7 on C driver and vista on D drive.then i apply crack to both of them one by one by booting in it.upon restarting, both OS has again reverted back to trial version.

for this.
*i have NOT defragmented C drive,i just simply installed win7 on C and vista on D.

please tell me what way i do reinstall both OS that both keey working.

Hi and welcome to windows7forums.

You see this behavior because of the cracks you're using, which we do not discuss in our forum. Sorry.

Kind regards.
