View Full Version : HELP Grub problem after update

31st December 2008, 08:52 PM
Yesterday I finally finished my transition from XP to Fedora. Later, I installed some updates with the software updagrade tool. Today, my wife was using it and it prompted her to reboot. Now, I don't have the message that tells me I have three seconds to push any key for kernal options, and it gets stuck when it tries to load GRUB.
I have had issues with this box ever since I upgraded from core 8 to 9.
I have loaded a puppy linux distro to have access to the machine. If it tried harder I might be able to find the directory where the kernal is.
So I have to re-install grub? or is it simpler than that?

It sounds like you are never making it to the GRUB splashscreen and/or menu. That implies that the GRUB stages are busted. And it is not an unheard of thing immediately after a yum update. The usual thing to do for it is re-install the GRUB boot loader.

Yes, that is my assessment too. Can I do that while running Puppy Linux?
I tried mounting all the drives in Puppy, it isn't all there, actually, some are there that shouldn't, and one is missing. Puppy is only loaded in RAMdisk, so I guess there is a hidden partition that I didn't know about left over form XP. But I can't see the partitions that should have GRUB and Fedora installed on it. I'll keep at it.

Something isn't right.
I cna't see all of the partitions. I have hdd1 which is a hidden 4.3G vfat partition I didn't know about until now. I have hdd2 which is where all my mp3s and movies are. then I have hdc1, it is 196 meg ext3 filesystem, but my master drive (with every thing important) is an 80 gig drive with several partitions. I can't see any of those partitions in puppy linux. This drive is there and powered on, my bios can see it. I can't mount it no matter what I try because it isn't there. I apparently found the swap space.
So I can't re-install grub. I can't find the boot dir. I can't get to my personal files to copy them. I'm Fracked.
Below I pasted from terminal, hdd2 isn't mounted but hdd1 is and not showing up.
Some one help please.

Well, if Fedora was working before the update, and GRUB is now busted after the update, then it's a commonly observed thing. Nothing should be missing. Just try re-installing the GRUB boot loader for Fedora. But if it were me, I would forget about that Puppy LiveCD and boot with the Fedora DVD (or the 1st CD) and enter linux rescue to do the work by the classic well-known method. But you should do what you want, of course.

i use the system rescue cd http://www.sysresccd.org/Main_Page

fdisk -l

"find the one thats noted as boot with the *"

"mount that to /boot"

mount /dev/sda1 /boot

"then install grub"

grub-install /dev/sda

reboot and you're all set

I had forgotten all about the rescue CD. Stupid brain. It's late now. I'll try it in the morning.
Thanks. I hate it when I make things harder than they have to be.
