View 1 Replies View RelatedUbuntu :: Getting Grub Error 17 On Reboot Attempt?
Aug 26, 2010Well about a week ago my computer acted a bit funny and upon attempting a reboot I hit grub error 17, and really haven't been able to make it past it. A had my original OS on it and get some files off and backed up at least. Backing up, I've only used a single OS of Hardy Heron. I don't understand why I'm being affected by this error when all I have is two harddrives that are used as unbroken partitions. Best advice I've used is to use a live disk, however the one I've currently got is for Lucid Lynx. I'm not sure whether I need to go and get the old version of a live disc since all I want are my files.
I'm content to update to the newer version (though part of me wants to wait for the next one since it's only a few weeks away.) If I could get my system running as it was that'd be great too. I believe the harddrives are fine since both are recognized in bios, just when running the live disk it asks if it wanted to install it or try it first. When running in the trial of Lucid, I can see the second harddrive and access files as I could on Hardy, but I can't see the main one. I really don't know what to do and am considering just starting over and cursing the loss of the data I want to preserve.
Ubuntu :: Xubuntu (or GRUB) Loads Only After Reboot?
Nov 12, 2010Whenever I power on my Xubuntu machine, GRUB does not load until I reboot. Once the system is running, I can reboot back into Xubuntu but if I power down GRUB does not seem to load. I've got the system to power on at 8am every morning but the fact that I have to reboot it is really annoying me.
Update:
Reinstalled GRUB to the master boot record of my first hard disk and it solved everything. I had to follow the second part of this guide to get it to work:

Ubuntu :: Reboot From Command Line To A Different OS?
May 20, 2010I would like to know if I can reboot my headless ubuntu machine from command line to a different OS on the same disk. To clarify, I want to do this without having to manually choose in GRUB.
OS1: Ubuntu on sda1- it is the default OS in an always on server.
OS2: Fedora on sda2 - have to login into this once in a while.
There are no monitors attached with the machine. So I cannot manually scroll through grub and choose Fedora. I want to know if there is a command I can issue remotely to the Ubuntu server to reboot to Fedora.

Nov 24, 2010I created a new partition in Windows Vista which, after rebooting, screwed up Grub. I believe that I need to reinstall Grub and everything should be fine, and I remember reading the command to do this on this forum, but I can't find it. When I boot, I now get a black screen with white letters instead of the Grub boot menu. It says something about "Minimal Grub" at the top and gives me a prompt that looks like this.

I can boot the live CD and I have internet access with it, but I can not remember the terminal command to repair Grub. Can someone tell me this command?
Software :: Unable To Boot Into GRUB Loader: GRUB Command Shell Boots Up?
Sep 2, 2009A failed upgrade, from disk images, of Fedora 10 to 11 resulted in no GRUB bootloader main menu appearing on bootup (no WIN, no LINUX choices from which to boot). I am booted directly into the GRUB command shell...so, no WIN, no LINUX, nothing. And my understanding of GRUB shell commands is very low.I have 2 hard disks, WIN on the first, LINUX on the second. I believe GRUB Bootloader is on the first disk.Sadly, I have no external install media.An old grub.conf hardcopy indicates that root =/dev/sdb2, root (hd1,0), kernel /vmlinuz....olderversion...(relative to /boot),initrd /initrd...olderversion... (relative to boot). and WINDOWS on (hd0,1), with chainloader +1
I need to somehow get past this grub shell, and re-install/re-instate the grub bootloader, so it can boot normally.What grub command(s) must I use? I've played around with the commands, but with no success.I worry that if I can't resolve this, the whole machine may be useless.
Ubuntu Installation :: No Grub Menu Screen After Reboot
May 21, 2010I just installed Ubuntu on the second partition of my hard drive. I have Windows 7 installed on the first partition. My problem is is that when I rebooted after a successful OS installation and apparent grub install, it went straight to boot up Windows 7. There's probably a simple way to get the grub menu to appear that I'm unaware of, right?
View 9 Replies View RelatedUbuntu Installation :: Choosing Kernel On GRUB Causes Reboot?
Jul 8, 2010I recently decided to venture into the world of Linux/GNU by installing Ubuntu.
Before installing, I had a 190gb partition for windows 7 and 45gb of unallocated space. Through Wubi, I used the advanced partition editor to make a 6gb swap partition and a 22gb root partition for Ubuntu. All went well, but when I rebooted, I was unable to choose linux.
I installed Ubuntu by using Unetbootin to put the Ubuntu ISO on my USB drive. After installing, I disconnected the USB drive, and I was unable to choose the linux kernel option on the GRUB menu. When I do, my system just restarts and presents me with the GRUB menu again. However, windows 7 boots up perfectly.
I'm assuming that GRUB is somehow trying to boot the linux kernel from the USB. How do I change it to boot from the installation I made on my harddrive?
Ubuntu :: GRUB Blocking Windows Chkdsk On Reboot?
Nov 25, 2010I'm running a dual-boot with Ubuntu 10.10 and Windows XP with GRUB. There are a few corrupt files on my XP filesystem, so I scheduled Windows to run Chkdsk on restart. I restart, select Windows in GRUB, and the screen shows saying it will run Chkdsk, press any button to cancel. Without me touching any buttons, it cancels it.
View 5 Replies View RelatedUbuntu :: Fails To Reboot After Updates Gets Stuck In Grub?
Mar 9, 2010Just installed Ubuntu a month ago (installed within windows), and for the 2nd time it has gotten stuck in grub upon restart after doing an automatic update. Last time, I reinstalled from the CD, but I can't do that every time. Learning how to start up from grub would probably be worth learning so I don't have to use the CD. But fixing the problem is most important. It makes me wonder if it was a mistake to install Ubuntu from within Windows (does this mean I have "wubu"?). I did find a webpage on booting Ubuntu from grub, but I could not get the kernel to load, regardless of if I used the instructions for wubu or not.
View 3 Replies View RelatedFedora :: GRUB :: Menu.lst :: GRUB Starts In Command Line?
Dec 1, 2010Code:
grub-install -v
grub-install (GNU GRUB 0.97)
I loaded GRUB, and now when I reboot it goes straight into the 'grub>' command line. Initially GRUB had the root as (hd0,2), whereas the boot is on (hd0,1)...(hd0,2) is my '/home' partition, and (hd0,1) is my '/' partition... So on a bootup I ran...
Code:
root (hd0,1)
setup (hd0)
Now when I boot I still get the 'grub>' command line, but now the root is correct.
From 'grub>' I can type...
Code:
grub> configfile /boot/grub/menu.lst
GRUB will then show the menu, and I can click the listings to load them. All's fine, but why doesn't GRUB just load the menu.lst without my prompting? How can I automate this process of typing 'configfile /boot/grub/menu.lst' each time I boot?

Ubuntu Installation :: Grub Rescue Prompt On Reboot After Update
Aug 8, 2010Installed 10.04 on my daughters laptop from within windows Vista. All went OK but I had two boot loaders, i.e. turn on laptop and I would get the Windows loader asking if I want to boot in to windows or Ubuntu. Upon selecting ubuntu I would get the standard grub loader that I have on my PC. Did an update a few mins ago and it asked me to update grub which I did and as there was only one disk showing clicked forward. Now on reboot I have grub rescue prompt, no such device. Hard drive is a single 80 gig drive with windows on one partition and ubuntu in another. Have the live cd so can boot from that I guess. What do I do next?

Ubuntu Installation :: Grub - Ran An Update And On Reboot Get A Kernel Panic Error
Mar 24, 2011I have a new acer machine which runs fine on 10.10 mythbuntu desktop livecd. Install seemed fine.
Then I ran an update and on reboot I get a kernel panic error. Research on this reveals it as a very deep subject which can consume many hours, so I opted to reinstall.
This time with ubuntu 10.10. I've tried different CDs, liveusb. Same errors.
So, the question is this - where do I concentrate my efforts - somewhere ubuntu doesn't like this machine, or grub. Does a reinstall overwrite the grub install too? Or do I have a bogus grub install I need to purge before I will get anywhere.
