problem dual booting lenny and fedora 12 menu.lst

[blackpearl]

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

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 :

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

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.

:D:D:D

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
