Grub Help Please

[nujinini]

Hi!

I added Fedora 12 in one new partition and after installation and reboot, grub only showed the new Fedora 12 and my XP.

And so I did the following:

grub> find /boot/grub/stage1
 (hd0,4) 
 (hd0,7)
 (hd0,8)

grub> root (hd0,7)

grub> setup (hd0)
 Checking if "/boot/grub/stage1" exists... yes
 Checking if "/boot/grub/stage2" exists... yes
 Checking if "/boot/grub/e2fs_stage1_5" exists... yes
 Running "embed /boot/grub/e2fs_stage1_5 (hd0)"...  19 sectors are embedded.
succeeded
 Running "install /boot/grub/stage1 (hd0) (hd0)1+19 p (hd0,7)/boot/grub/stage2
/boot/grub/menu.lst"... succeeded
Done.

grub>

Now, I was able to bring back the Grub menu to show everything except the Fedora 12.

hd0,4 is Fedora 10
hd0,8 is Fedora 12
hd0,7 is Mint 7 - This is where I want to install Grub.

May I ask for some guidance on how to properly repair my grub and be able to show everything please

Thanks!

I am still learning grub 2 myself nujinini. And being a Debian type guy. I am not well versed in rpm distros. To make a long story short. Super Grub Disk is now getting into grub 2 isos. Just in case you didn't know.

Please help test Super GRUB2 Disk 1.98s1 RC1

Isn't GRUB Legacy default Boot Loader of Fedora 12?

hd0,7 is Mint 7 - This is where I want to install Grub.

I am not getting it. Do you want to use GRUB of Mint instead of Fedora? You can install Mint 7's grub and entries of Fedora 12 and 10 in its menu easily.

Yes dc, It's using GRUB Legacy.

I am not getting it. Do you want to use GRUB of Mint instead of Fedora?

I notice that if I install Fedora last, it does not show the other linux OS in Grub. Only XP.
Unlike in the other OS I tried. That' the only reason why I want to use Mint's Grub.It shows everything except now. It did not show my freshly installed Fedorq 12.

You can install Mint 7's grub and entries of Fedora 12 and 10 in its menu easily.

I would love to learn how to this please!

I notice that if I install Fedora last, it does not show the other linux OS in Grub. Only XP.

This a problem with all RedHat based distros. Installer detects all OSes except Linux. I don't understand why Fedora Team has removed Linux detection from its installer explicitly.

There are a lot of ways to add entries of Fedora OS in Mint Menu.


1) Mount / partition of Fedora 12, copy first title block (title, kernel and root lines) from its grub.conf file and paste in menu.lst file of Mint.

Or

2) Install Fedora's GRUB in boot sector of its root partition and chainload it. You can install GRUB in boot sector during or after installation.

Boot up in Rescue mode using Fedora 12 Installation CD/DVD and execute grub command in Rescue Shell.

grub
grub>root (hd0,8)
grub>setup (hd0,8)
exit
exit

Above code will install GRUB of Fedora 12 in its boot sector instead of MBR.
Add this code in menu.lst file of Mint :

title Fedora 12
rootnoverify (hd0,8)
chainload +1

On selecting Fedora 12 in GRUB Menu of Mint, GRUB Menu of Fedora 12 will appear. You can set hiddenmenu option and timeout=1 in Fedora's grub.conf file to make it invisible.

Second method is a bit lengthy but it has a few advantages. You don't have to edit Mint's menu.lst file after updating kernel of Fedora. Mint is calling (chainloading) Fedora's GRUB and whenever you update Fedora, its GRUB will be updated. No need to change anything anywhere.

I chose the 2nd option and was able to do it.

Boot up in Rescue mode using Fedora 12 Installation CD/DVD and execute grub command in Rescue Shell.
Code:

grub
grub>root (hd0,8)
grub>setup (hd0,8)

quit

Then I boot into Mint and I added this code in menu.lst file and since this was added in the end of the list I also added divider:

# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/sda9.

title Fedora 12
rootnoverify (hd0,8)
chainload +1

After I made a reboot, the Fedora 12 was already included in the list of Mint Grub.
When I clicked on it, it gave me another menu.
And when I clicked on Fedora 12 again, it did not boot but just remained as it is.

Do you think I made a mistake somewhere?

[devils casper]

Post the contents of Mint's menu.lst file here.

Is it a fresh install of Fedora 12? Did it boot up fine earlier?

[nujinini]

Yes its a fresh install. It boots up fine.
