I have Windows xp 64bit and windows 7 64bit both installed on same hdd but have it partitioned where they both have their own partition. I know im supose to be able to reboot and select my os i want to boot up in but when it reboots and starts back up all it does is go through the normal loading sections and passes the normal info of showing the dos that flashes at start (forgot what it was besides loading info). Every time now it will only load into Win XP and I cann't get back to load into my Win7. Can someone help me with being able to choose my os i wish to boot too. Thanks for any and all help on this issue.
