I have XP on my C drive. I'm going to install Vista on my second drive (D) w/a dual-boot setup. I know Vista will see itself as C drive and XP as D drive and vice-versa w/XP. After I get Vista setup and running nicely (already experimented w/it on a small partition, worked fine) I will want to delete XP completely and just run Vista. Will I have any issues? (Like w/MBR or D drive now being C drive?)

Thanks much,
Harold

You'll have a problem with the MBR on C:. But after formatting the XP drive, switch them and run startup repair from the Vista DVD and you should be all set.
