booting

Ok so the picture is this, I have P5N32-SLI MB with 3 HDD's connect via sata, so the first 2 are connected as RAID and i have Windows installed there and i've decided to install Mandriva on the other, and this is where confusion begun... How can I make a boot screen wich would allow me chose whic OS i'd like to load. I've tried fiddeling with BOOT.ini but just couldn't make it right, so long storry shot - please help :mrgreen:

Thank you :)

Mandriva will install its own bootloader called GRUB, which will be done automatically and it will give you the option to boot any running OS's on your system.
