It seems that I hit following bug in Fedora 14 - I deselected installing grub into the MBR while using the graphical installer, because I want to use an existing grub instance.

Now, I want to look up the grub.conf or menu.lst in the new installed Fedora 14 system to adjust my existing grub config - but I cannot find them anywhere.

I just information about how grub-install and gruppy are not able to create a grub.conf from scratch.

Thus my question: How to generate a grub.conf from scratch in Fedora 14, if it is missing?

Update: The point is to get the set of default kernel options a grub.conf includes, when created by the Fedora installer.

I have booted the fedora installation via grub and only setting the 'ro root=' options which worked.

However, it would be great if someone could post a standard generated grub stanza from his/her Fedora 14 system to see the kernel parameter differences.

The following is the grub.conf present immediately after installation of Fedora 14 within a VirtualBox VM. During installation I used all of the default options.

# grub.conf generated by anaconda

#          initrd /initrd-[generic-]version.img
#boot=/dev/sda

thanks a lot - btw, the manpage to dracut seems to describe some Fedora specific kernel parameters that are present in that file –  maxschlepzig Nov 7 '10 at 17:49

I'm not sure if Fedora 14 uses the legacy version of GRUB (0.97) or the new version (1.xx); you can check by running grub --version on the command line. Either way the configuration file format is pretty simple; the legacy one is documented here, and the newer one here. The newer one even comes with grub-mkconfig to generate a configuration file for you

Fedora 14 uses legacy GRUB - the syntax is not the problem: I am just worried about default kernel options that a default config file from fedora might include, but I don't know anything about ... –  maxschlepzig Nov 6 '10 at 20:35
