[SOLVED] edit grub OS menu fedora 16

ReverendDangles · 04-16-2012, 10:15 PM

Hello, I have partitioned my old laptop to dual boot Win 7 and Fedora 16.
When I turn on the comp the grub menu has the past 3 updated fedora as well as 2 windows 7. My question is: How can I edit grub where it only shows AT MOST the current fedora and only one previous update? I would
greatly appreciate any help.

you edit the /boot/grub/grub.conf ( or menu.lis ) as root
but the old kernel listings ARE AN emergency back up listing

fedora ( by default) keeps the last three kernels and the last two as BACK UP
updates can and have been known to FUBAR a fedora install ( or the user dose)

keep them

but windows should only have one and only one entry
unless YOU changed it
the "other" operating system is windows

Have a look at "installonly_limit" in /etc/yum.conf
Must admit I generally only increase it, not decrease. Your system, your choice.

Rubbish - of course you can get more than one Windows entry; the normal system, and the OEM recovery partition for example.

the "recovery" partition would show as a mount point (in mstab) and not in the grub.conf as a operating system

however fedora is well known to put grub on top of the "recovery" partition ( MBR)
or mis set up the partition number(hda1) because of it

If it has Windows boot code in the recover partition - many do, and can be invoked by using a "special" key on boot - os-prober will find it and build a boot entry for it.
End of discussion.

Mounting afterwards is irrelevant.

Let me know if this will yield any negative consequences.

Under root I went to /boot and made a folder for my older
backups and moved my older versions into it and then ran:

Code:

grub2-mkconfig -o /boot/grub2/grub.cfg

After restarting my computer the GRUB menu only showed
the latest backups that I did not put into my oldversion
folder.
