All right I just got time to format the XP drive and everything is almost fine now. A quick final question:
How do I get rid of the "Windows boot manager" screen?
It still appears showing me the Windows XP along with the 7 option to boot from.
Should I Install EasyBCD and go to 'Add/Remove entries', delete the Xp Entry and then go to 'Manage Bootloader' and click in the 'Write MBR' button?
I can go to Control Panel/System and Security/System and click on Advance system Settings then click on the Advanced Tab and go to Settings under the Startup and Recovery section and from there I can uncheck "Time to display list of operating systems" to skip the boot manager screen but I want to get rid of the XP option.
Just asking before I produce a mess, thanks guys.
