installing grub2 to MBR, looking to do this correctly.
installing grub2 to MBR, looking to do this correctly. - FedoraForum.org

The command to generate grub2 to MBR;

Code:

sudo grub2-install --recheck --root-directory=/ /dev/sda

**devils casper** · 09-30-2012

Edit Ubuntu's grub.cfg file.

Code:

cd /boot/grub2
sudo chmod +w grub.cfg
gkdu gedit grub.cfg

Add following code before "### BEGIN /etc/grub.d/40_custom ###" line in grub.cfg file :

Code:

}

Save file and remove write permission of grub.cfg file.

Code:

sudo chmod -w grub.cfg

Reboot machine and check if Fedora boots up fine.

Its easy to re-install GRUB2 in distros where root partition is not a Logical Volume. I am not sure about GRUB2 re-install command in LVM system. I don't have LVM in my test machine to experiment GRUB install.

If Ubuntu's GRUB2 is being used then there must be Ubuntu's grub.cfg file somewhere. Let me check in my Ubuntu machine.

$ sudo find / -name grub.cfg

Code:

 
/boot/grub/grub.cfg
/usr/share/doc/grub-common/examples/grub.cfg

grub.cfg is under /boot/grub.cfg

$ sudo find / -name grub2 -type d
$ sudo find / -name GRUB2 -type d
both without printout

**devils casper** · 10-01-2012

Edit that grub.cfg file and add an entry of Fedora in it.

Code:

cd /boot
sudo chmod +w grub.cfg
gksu gedit grub.cfg

**satimis** · 10-01-2012

$ cd /boot/grub

$ ls | grep grub

Code:

grub.cfg
grub.cfg.ORIG_20120930
grubenv

$ sudo chmod +w grub.cfg
$ sudo gedit grub.cfg

adding follows before

grub (window) didn't start. I have to press "left-shift" key to start it.

Selected;[code]
Fedora (3.5.4-1.fc17x86-64)

to start Fedora.

Please advise:
(1) How to make grub (window) start automatically without holding lef-shift key?
(2) How to add "recovery mode" for Fedora?
(3) If I need Fedora started automatically how to do it?

TIA

Post the contents of /etc/default/grub folder too.

You GRUB Menu has a lot of entries. Do you want to keep that all or remove a few? Do you want to keep/require memtest entries too? I would suggest you to remove unused, older Ubuntu kernels too.
