i think u need search in google for how to configure the grub. you will find many solutions about it.Like: http://www.cyberciti.biz/tips/configure-ubuntu-grub-to-load-freebsd.html vi /boot/grub/menu.lst Append FreeBSD boot Configuration: title FreeBSD 7.0 root (hd0,a) kernel /boot/loader Save and close the file. To see changes or to boot into FreeBSD reboot Ubuntu Linux box. Where, title FreeBSD 7.0 : Start a new boot entry. User always sees this title and hit enter key to boot os. root (hd0,a) : Actual part is to select the correct root partition. The root option set the current root device to the device, then attempt to mount it to get the partition size. In above example - hd0 is your first hard disk i.e. hda in Linux. In grub hda is hd0. Likewise your first, second partition on the first hard disk – hda1, hda2, becomes hd0,0 hd0,1 in Grub. In short, you are asking to use first hard first partition (remember FreeBSD use a,b,c names to represent partition names). If you have installed FreeBSD on third partition then you need to use following root statement: root (hd0,2,a) kernel /boot/loader : Use to load the primary boot image. FreeBSD use /boot/loader to load rest of kernel and os. 2009/3/29 Onkar <onkar.n.m@xxxxxxxxx>: > Hi, > I am working on some projects for Linux as well as freeBSD OS.
