Is there a way to stop Grub from scanning the optical drive for boot media before getting to the boot menu? Or to skip this step? (I have the drive excluded from the BIOS's boot menu but then Grub still checks it anyway)
View 1 RepliesI just installed ubuntu as a learning tool. It was going fine until the next day after the install. This happened on two reinstall of ubuntu server 10.4. All was installed was lamp, squid, privoxy, tor, shorewall, and phpmyadmin. I have added 3 websites to the server.
Today, I noticed my internet stopped responding on my other pc which is linked to my server for internet access( privoxy). When I turned on the server, I noticed the screen was purging out random lines. I don't know what they mean, but it was a never ending series of lines filling the whole screen. To stop it, I ctrl+c. Some of these lines read usb, keyboard, mouse, etc. I am guessing the system went hay-wired.
When I reboot the machine, it did it again. This time I don't have the cmd prompt. I didn't know another other way to properly shutdown so I just cold reboot the machine. The next time it booted up, all seems normal like it always have been. My sites, internet is working.
I probably didn't provide enough info to diagnose this behavior. As mentioned before, it happened the first time I installed the server and it is happening again with the same applications installed.
Edited: It happened again. Some of the lines I could make out are these.
Code:
Bug: unable to handle kernal NULL pointer deference
Kernal panic-not syncing: Attempted to kill the idle task!
Error panic occured: Switching back to text console.
The server froze at this point.
After some system updates, I now have the Grub menu appearing every time I boot my computer. Is there any way to disable it, or make it automatically boot whichever entry is selected by default? I only have one operating system installed, so there's not much of a point to having to press enter every time my computer starts up.

I have this one system, a PowerEdge 1550, that for some reason WILL NOT boot using a UUID, and will only boot if I edit the first entry in grub, remove everything to do with UUIDs (completely delete the search line, replace root=uuid=[uuid] with root=/dev/sda1). I can't seem to make these settings stick and now with 10.10 there's no longer a menu.lst to edit. So, in short, I need grub to stop trying to boot based on a UUID. Absolute paths, baby. That's what I need.

From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

============================= Boot Info Summary: ==============================[code].....
after doing an upgrade to 10.4 and updating grub I get this message. how do I address this
[Code]...
I've been using Linux for over a decade, so no need to worry about the obvious. I'm positive that I have my partitions/install correct. What has me baffled is that Fedora 14, which uses GRUB 0.97 (GRUB legacy) - boots Windows flawlessly every single time on the same hardware, but Ubuntu's (or the upstream Debian's) GRUB legacy do not - even though they are based on the same upstream code from the GNU Savannah servers.
No matter what I've tried I cannot get the Debian or Ubuntu version of GRUB/GRUB-legacy to boot any recent Windows 64 beyond XP (Vista or 7). All that it does is resets the computer when Windows attempts to boot, without an error. GRUB is notoriously difficult to compile, so before I try to compile code from RedHat's archives - any thoughts,experiences, similar issues - whatever?
I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?
The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).

I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:

I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted

I have tried the testdisk/update-grub method, but it didn't work.
So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?

View 9 Replies View RelatedI've got myself the curious situation where, when I boot the system, I can get grub to start, but it always drops to the prompt.
I can run:configfile /grub/menu.lst
and this brings up the menu with no problems, and from there I can boot the system to either linux or windows. What I don't understand is why it wont go to the menu in the first place?As far as I can tell, grub/Kubuntu got confused when installing, as each of the hd#,# settings in the menu.lst have needed tweaking to let the system boot. (e.g. windows is actually hd0, but the original install had it at hd2. Likewise linux is on hd1, but the menu.lst had it at hd0). I've happily tweaked these to make the system boot, but would appreciate any help in convincing grub to actually load the menu without me having to use the prompt.
A 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.
I have used CentOS for a while and have never run into this issue. I searched all over and didn't see a similar issue anywhere, I did an install of CentOS as a server (no GUI) with only the base. Partition is /boot ext3, size of 100MB. The rest of the drive is partitioned as / with ext3. This is being done on a CompactFlash card of 32GB in size. The BIOS sees it as an IDE drive.
When the install completes and the system reboots, the grub stops at the grub> prompt. There is no menu for OS options. If I do the following commands:
grub>root (hd0,0)
grub>kernel /vmlinuz-2.6.18-194.el5 root=LABEL=/
grub>initrd /initrd-2.6.18-194.el5.img
grub>boot
I started another thread about this to get help booting into openSUSE after Fedora rewrote my bootloader and deleted all other entries. I managed to fix it but I never did find out why the following commands caused my system to boot to the grub shell instead of the grub menu.
Code:
grub
root (hd0,3)
setup (hd0)
quit
reboot
Can anyone explain to me why these commands caused my system to boot directly to a grub shell? It's as if there were no /boot/grub/menu.lst files for it to use, but after I got everything back to normal, the files were still there.
If it helps, this is how the drive was setup before and now, except Fedora was on /dev/sda4 and has since been deleted.
Code:
Device Boot Start End Blocks Id System
/dev/sda1 1 262 2104483+ 82 Linux swap / Solaris
/dev/sda2 263 13316 104856255 83 Linux
