I just got a second hard drive so that i could install FreeBSD and slackware onto it for my computer. (got it because i was out of partitions on the first drive). The first drive is a serial ATA WD drive, the second drive is an IDE WD drive. I just want to set the system up so that it will basically startup with grub bootloader, and then let me pick which OS to boot from, listing them from either drive. This is my first system with multiple hard drives, so my question is simply, how do i do this?
