problem dual booting lenny and fedora 12 menu.lst

blackpearl · #1 17th February 2010, 12:47 AM

hello everybody
i had recently installed fedora 12 in a system running debian lenny in (hd0,0), its grub is installed in mbr and the grub of fedora is installed in the installation partition of fedora .I defined a separate partition /boot for debian but for fedora i used the available space for boot swap and /.
i booted with live cd to copy the grub.conf of the fedora to add it into menu.lst of debian but i have got "error 15 : file not found".i need hel and i will be thunkfull (sorry for my english mistakes -3 rd language)

this is my menu.lst

Code:

title		Debian GNU/Linux, kernel 2.6.26-2-686
root		(hd0,0)
kernel		/vmlinuz-2.6.26-2-686 root=/dev/sda8 ro quiet
initrd		/initrd.img-2.6.26-2-686

title		Debian GNU/Linux, kernel 2.6.26-2-686 (single-user mode)
root		(hd0,0)
kernel		/vmlinuz-2.6.26-2-686 root=/dev/sda8 ro single
initrd		/initrd.img-2.6.26-2-686


title Fedora (2.6.31.5-127.fc12.i686.PAE)
	root (hd0,8)
	kernel /boot/vmlinuz-2.6.31.5-127.fc12.i686.PAE ro root=UUID=d6a1b08d-156c-47d0-bf70-3e63731da995  LANG=fr_FR.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=fr rhgb quiet
	initrd /boot/initramfs-2.6.31.5-127.fc12.i686.PAE.img

these are the result of commands like df -h ; fdisk -l and so on

Hello and Welcome to FedoraForum.org ,

I have found it easier to boot multiple OS's using a chainloader in menu.lst. If you use a chainloader you won't have to do any of the copy/past. The syntax for a chainloader looks like this :

Code:

title Fedora 12 (sda8)
	chainloader (hd0,7)+1

Hope this helps,

Ky

thank you so much
it did work i am using fedora now
it was so helpfull
it was so simple and so easy that i didn't believe
i puted these tow lines into menu.lst of my debian lenny

Code:

title Fedora 12 (sda9)
	chainloader (hd0,8)+1

with changing sda8 with sda9 and (hd0,7)+1 with (hd0,8)+1 since i have installed fedora on sda9 not sda8. .

if i am thinking correctly , if i install on sda9 i have to change (hd0,7) with hd0,8)

Note: I think this method won't work if i didn't install fedora's grub on its root partition or if i created a separate /boot partition ?

thank you so much kyryder for your precious help.

Congratulations, I am glad you where able to make it work!

Yes you are right, the chainloader method will only work if you put grub in the same partition as the new OS.

The reason I thought Fedora was on sda8 was the output from fdisk -l shows that your boot partitions is sda9 /dev/sda9 * 3210 6374 25422847+ 83 Linux with the "*" so I wrongly thought it was lenny's grub.

Just so you know for the future, in the title line the "(sda?)" and in the chainloader line the "+1" are not needed by grub. That is just a trick to make the lines more human readable and help keep track of what is what.

Congratulations again,

Ky
