Well i just installed vista on my comp…and just check its feature…but what happen is every time i start pc it shows 2 options
and vista remain at default and if i m not there… vista loads…
i want win xp to be at default position. What should i do???
Just download VistaBootPro from this site and install in Vista.
VistaBootPRO - Go PRO with Windows Vista and VistaBootPRO
Run it and you can change the default boot option, wait time as well as edit the boot menu strings through a Graphical Interface. That ugly “other Operating system” menu item can be changed to Windows XP. 
.
Reps appreciated… 
Click on Start>Right Click on My Computer>Properties.
Click Advanced system settings. Click settings under Startup and Recovery, change the default OS selection.
