<SOLVED> Grub: edit to include MSDOS boot

[RenegadeAbe]

I have a fresh install Hardy as well as fresh install MSDOS 6.2 - (Don't ask me why but I need it for something archaic) I stopped bothering to multiple boot ever since Hoary so I never played around with Grub and fstab.

I installed MSDOS first on a 2GB partition then installed Hardy after on the same HD.
Install went fine but I cant select to boot MSDOS. MSDOS is just not there.
How do i include it ?

I can GUI mount my MSDOS partition and from the info it tells me that
it is /dev/sda1 I'm pretty sure it's FAT16

Here's my fstab file
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda5
UUID=d2ac5d45-176b-4da2-b7da-39d2cf8a6680 / ext3 relatime,errors=remount-ro 0 1
# /dev/sda6

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0


Here's my Grub menu.1st
title Ubuntu 8.04, kernel 2.6.24-16-generic
root (hd0,4)
kernel /boot/vmlinuz-2.6.24-16-generic root=UUID=d2ac5d45-176b-4da2-b7da-39d2cf8a6680 ro quiet splash
initrd /boot/initrd.img-2.6.24-16-generic
quiet

title Ubuntu 8.04, kernel 2.6.24-16-generic (recovery mode)
root (hd0,4)
kernel /boot/vmlinuz-2.6.24-16-generic root=UUID=d2ac5d45-176b-4da2-b7da-39d2cf8a6680 ro single
initrd /boot/initrd.img-2.6.24-16-generic

title Ubuntu 8.04, memtest86+
root (hd0,4)
kernel /boot/memtest86+.bin
quiet

thanks in advance for any help.

Re: Grub: edit to include MSDOS boot

I've not used MSDOS (recently), but ...

Looks like one hard drive (=> no need for map commands).
sda1 = MSDOS, as you indicated
and in GRUB terms
sda1 = (hd0,0)
and we'll assume there is some sort of bootloader in the boot sector (= sector 1) of sda1 (?),

If so, you might try booting MSDOS by chainloading:


title MSDOS 6.2
rootnoverify (hd0,0)
makeactive
chainloader +1


That's it – try it.
Chainloader +1 => GRUB should read the first sector of (hd0,0) = the boot sector (we hope) and pass control to that bootloader in sector 1.

Re: Grub: edit to include MSDOS boot

Thanks Qqmike.
Worked like a charm.

I got up to the makeactive command last night before I read your post and it didnt work.
so I guess the chainloader +1 command is the lucky charm.

Thanks again

Glad you're back on the road again, RenegadeAbe.

(and looks like I got lucky with yet another GRUB tip that worked ... )
