I updated my grub yesterday using the command:
Quote:
sudo grub-update
and I rebooted and grub menu not coming now. I have a dual boot with Win7. Ubuntu 10.04 is installed with WUBI. I can run WIN7 but can't run Ubuntu now.
I installed on my system "window xp" and "rhel4 update 2" but due to some problem I removed my windows xp O/S and installed that again after that grub boot menu is not coming so I can't log in properly in linux system.C

I am testing my crash recovery strategy for my linux system and I am having trouble with GRUB. I am basically restoring my backup (i.e. tar) unto a different hard drive, but I am having problems getting the machine to boot without me having to type the GRUB commands at the GRUB prompt that is presented when the machine boots up off the new hard drive. I have tried to restore the MBR in two ways (the 2nd one is the one that gets me to the GRUB prompt):
1. Get the MBR off the original drive and write it unto the new drive (all via dd), but that did not work at all: the machine hangs right away during boot up. It seems to hang right at the point where the BIOS tries to read the MBR.
Code:
On original drive:
# dd if=/dev/sda of=mbr+part.bin bs=512 count=1
On new drive (new drive is now in place of original drive):
# dd if=mbr+part.bin of=/dev/sda bs=1 count=446 conv=notrunc
2. By using the FEDORA rescue CD, I installed grub unto the new hard drive as follows:
Code:
# chroot /mnt/sysimage
# grub-install --root-directory=/boot hd0
reboot and remove FEDORA CD Using the 2nd option above, I get the GRUB> prompt during bootup. I can then boot into the system by issuing the commands that are in the menu.lst file, followed by the "boot" command. However, I would like for those commands to happen automatically, just like in the original configuration. It seems to me that GRUB is actually finding all its stage files because I doubt the GRUB program (the one displaying the prompt) fits entirely in the 446 bytes it has on the MBR. So, it must be loading its stage 2 (and stage 1.5??) files from my /boot partition. However, if GRUB is loading its stage files off the boot partition, why does it not load/read the menu.lst/grub.conf contained in the boot partition also?
Code:
# ls -l /boot
total 22888

I have a vista/ubuntu 9.10 duel boot laptop. Last week the screen was broken so it went back to the manufacture. Before that I rename the /etc/grub.d/10_linux file and ran grub-update so that Grub will only show windows boot menu (in case it confuses the repairman) now I have the laptop back and I am eating my own medicine.how to restore my ubuntu boot menus? I can now only boot into windows, although it seems like I can go to my ubuntu partition and change back my grub.cfg (which I did not backup!)but I can't remember the menuentry details.Is there any way, other than manually change my grub.cfg, so that I can boot into ubuntu again?

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 have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.

View 1 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.
When I start the computer the boot menu doesn't prompt, when I try to load it manually it doesn't prompt neither, it just reset the command line.The grub.cfg was generated by update-grub.It's really annoying to load the kernel manually each time the computer starts.
View 3 Replies View RelatedI 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.

I have a used PC that came pre-installed with suse 11.2.Unfortunately, I do not have the install disk to use in case of whatever.I already know that when configuring a dual boot with Windows and Linux, it is recommended to install Windows first.I do not have that luxury now as 11.2 is installed and GRUB is the boot loader.Question is, if I boot the Windows 98 install disk on boot, how to not mess up GRUB and still add Windows 98 to GRUB menu?
One hard drive only here. 98gb free.It seems that W98 install will overwrite GRUB in this situation - causing problems. Maybe not, I don't really know for sure.I just need to install windows 98 on the same hard drive and if possible, have suse and w98 visible on boot in GRUB.
Code:
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?
Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen....nothing works except Ctrl+Alt+Delete....system reboots showing successful daemons shutting sequence.

I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?
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 can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.

I have tried the testdisk/update-grub method, but it didn't work.
I've been trying change the default OS in GRUB. I changed the value for GRUB_DEFAULT in etc/default/grub. However, when I run update-grub, I get the following error:
/etc/default/grub: 19: e: not found
After certain system-wide changes, like kernels updates, I obtain grub prompt on restart. However, if I put the hard drive into another computer (b), it boots up fine. Since, however, I use the present computer (a) regularly, I only use b to purge and reinstall grub using the chroot method. However, doing so every time is time consuming; and I cannot change anything in the defaults and run update-grub without obtaining a grub prompt on restart. How do I fix this?

sh:grub>
now what should i enter here so that i can come on the main ubuntu gui window..?
i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. 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
View 5 Replies View RelatedI would like to know if there is any differences on how to install and to configure GRUB 2 in the different architectures (BIOS/IBM PC-Compatibles, EFI/MacIntel and Corebbot)? Does the Ubuntu installer automatically recognize the different architectures and install the appropriate GRUB 2 package ('grub-pc', 'grub-efi' or 'grub-coreboot' according to the arch)? Or does it just install 'grub-pc'? Is the location of GRUB 2's configuration files different depending on the arch of the computer? Or are they all located in '/boot/grub/', '/etc/grub/default' and '/etc/grub.d/', no matter the arch of the computer? Are the files' structure and options to configure GRUB 2 ('/etc/grub/default' and the scripts in '/etc/grub.d/') different depending on the arch of the computer?
