I have a system that is now operating well with XP and OpenSuSE Linux. I currently boot through grub in the MBR. I want to install Vista, and use EasyBCD to manage the boot. What is the best way for me to proceed?
1) Install Vista then copy over your menu.lst to the neogrub configuration file from EasyBCD.
2) Install Vista, install GRUB to the bootsector (NOT the mbr), and then auto-configure a linux boot with EasyBCD.
Both are amazingly easy, though i think  might be a tad less complicated. Just email yourself a copy of grub.conf / menu.lst, and install Vista. We'll guide you through the rest!
