Debian :: Restore The 'full' Grub Menu?
Aug 5, 2010
Upon booting, the existing grub menu shows the Debian OS, but I also have Ubuntu installed on the same hard disk. It does not show in the menu. Previously I had Debian, Ubuntu, and Mint. In Ubuntu config file (menu.lst) I wanted to delete Mint and an old Ubuntu. I did so. In doing this I must have removed the 'full' menu.lst,leaving only Debian. So now I cannot boot into the new Ubuntu. I presently have only two OS on the hard disk: Debian and Ubuntu. I cant see Ubuntu, How do I correct this problem?

I am using grub 1.97beta. I have Ubuntu 9.10 installed. The grub menu list is full of Ubuntu 9.10 with two listings for each Linux kernel version. I really have no need to go back to older kernel versions. Can those be eliminated? How? I didn't find anything in the grub wiki but that doesn't mean I didn't miss it

I have two operating systems installed in my computer. one is Windows XP( sp2 ) and another is Ubuntu Linux 10.04Lts. I reinstalled Windows XP. After rebooting, the grub menu is not displaying, only windows is booting, there is no sign of Ubuntu. Is there any way to restore the Ubuntu or I have to freshly install Ubuntu again ?

this isn't really a security question, per se, so feel free to move. It is related to full disk LVM encryption though. Full disk didn't work for me with grub2 after running dd to a remote server, so I downgraded to grub1. No biggie. However, I have neither grub or grub2 as selected in Synaptic.Let's say I forget which I have installed. How would I determine what version of grub is installed at the moment. I'm assuming it's somehow installed on in the mbr but not on the OS. I didn't mean to do anything funky. Is that the normal setup? I'm deploying these systems to users and want to be able to troubleshoot issues in the future (hopefully that will not be needed!) grub --version does not work because it is not installed.

I have installed Windows 7 on my laptop . Now, it directly boot from Windows 7 . I think the MBR overwrote my grub . I have found two methods by google , but still does work .
1: boot from debian install CD, Alt +F2 switch to the console. "grub " "root (hd0,0)" "setup (hd0,0)".
2:boot from CD, mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt ; chroot /mnt ; grub-install /dev/sda.

A few days ago I installed my first Linux product, which is Debian 6.0, and I installed the GRUB booting device on my main boot record, as it was suggested that it was a harmless step to take. Unfortunately, some quirk in my system made GRUB believe that I had XP when in fact I have Vista, so the options I have now are to boot Debian or to boot XP which is not on my computer. In other words, I have to get rid of GRUB now, but I'm realizing that he's not such an easy customer to kick out. I have moved my Linux installation to another drive, but the old GRUB always stays in place, and my Vista is stuck there frozen for eternity. So after considering all kinds of possibilities, I have come to the conclusion that the easiest way to restore my original boot record would probably be to find its backup copy that I assume the installation program made, and to copy it back into the right address at the beginning of the disk. I don't have the Vista recovery CD, so I really have to do this manually. So now my questions are these: did the installation program make a copy of the boot track, and if so, where did he put it and under what name, and finally, what command can I use from within the Debian terminal, which is now my only tool left, to copy the content of thesaid file into the first 512 bytes of the hard drive? I know that would be a simple matter for any serious geek, I guess I must be a little rusty. Anybody feel up to it?

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
-rw-r--r--. 1 root root 1274567 2009-05-27 16:39 System.map-2.6.29.4-167.fc11.i686.PAE
-rw-r--r-- 1 root root 1274538 2009-06-16 22:27 System.map-2.6.29.5-191.fc11.i686.PAE

I have WinXP, Ubuntu 10.04 and Debian 6.0 installed on my Desktop.
After installing my latest distro, Debian 6.0 WinXP disappeared from my GRUB menu!
Relevant details are:
root@debian-peter:~# fdisk -l Code: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

Recently I installed Debuan "jessie". I previously had Windows 8.1 and Xubuntu installed. After installation Debian installed it's own version of GRUB, with entries for Debian, Xubuntu and Windows. The problem is that after I selected Windows when booting, GRUB menu no longer appears. It boots straight into Windows.
It's lenovo Ideapad z510 laptop, with special button that allows me to select between 4 options before booting - one of them is "Boot menu".
I didn't use it before windows "removed" GRUB, but now there are 2 options: Windows boot loader and Ubuntu. When I select Ubuntu it loads my old boot menu (from before installing Debian).
I thought that when I use update-grub from Xubuntu I will at least eb able to boot into debian. After I did that Debian option appeared in the GRUB menu, but it didn't work - black screen.
How to get GRUB menu working again (and avoid replacing it by windows boot loader)?

i just installed the Debian on my old laptop. The install went fine but after that, the GRUB menu loads and freezes. I simply can't do anything. I checked menu.lst and the timeout is set to 5 but still nothing happens. It won't load. I then tried to load with the "super GRUB disk"but the same problem - as soon as it loads from the CD, it freezes and I can't do anything. Before I had Xubuntu on the same laptop but there was no Grub menu. It simply loaded. There's only 1 OS on the laptop /currently Debian/ - no windows, no other Linux.

I am using Debian lenny (kernel 2.6.26-2-686).
I changed my menu.lst to use
root=UUID=<long uuid string>
instead of the good old
root=/dev/sd...
I did that because, if I boot with a usb drive attached to my computer, sda become sdb and therefor nothing works anymore since my friend Kernel can't mount it's root partition. BTW, it works wonders using the UUIDs. The story darkens each time there is a kernel update, dist-upgrade resets my menu.lst back using the /dev/sd... format. and BANG... no more booting again. I am good to change my menu.lst back each time.

I would like to try the rawhide updates. If messed up my PC's couple of times so now before I do anything I would like to roll back changes and resort to last working kernel ( and related s/w) in case that fails . HOW do I do it? ( c.f Windows Last good session ) ALTERNATIVELY folks - is there a way you can backup and restore to full accuracy all your previous kernels .- I mean just inset the CD .It will identify the partitions , then it will ask you "where you want to restore them" and then it just restores the prev. image.

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) 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. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

I have Debian Jessie 8.0 amd-64 installed. It is a dual boot system with Widnows 8.1 alongside. Both the systems work fine with a few glitches coming at times on jessie. But I assume it should get stabilised with time.
Problem is:
The usb keyboard is no longer detected until the GRUB stage crosses.
* This implies I am unable to press F2 to enter into BIOS
* I am unable to chose Windows 8.1 by using arrow key on the keyboard.
When the default system (first in the grub list), in this case Debian is selected after time runs out then the keyboard comes back to life and works properly thereafter.
So far I have tried the possible solution given at [URL] .... but it did not work.

I have an old version of DSL installed, followed by XP. On a further partition I installed Debian 6. Installation of Debian went smoothly, including the final detection of the other two OS for Grub. I had expected that the Debian-version of Grub would override/overwrite the one that came when I installed DSL.
It did not - when I boot, Grub comes up with the old DSL menu, in which Debian is not included.
From what I've been reading about Grub, there's two "fases", first in MBR, that points to the second part where the actual boot-commands are given, in my case stored in DSL.
When I open the Grub config-file in Debian, both DSL and XP are correctly listed.
Now I'm not sure what to do - I'm a bit hesitant to try and point grub-fase-1 to Debian (if I can write the correct lines at all, I'm very insecure on that) - if that fails, I cannot boot at all. But I'm not really sure either how to formulate a new rule in the DSL-grub, to make Debian boot from the existing menu.

I have a Laptop where I installed both Fedora 11 and windows 7 dual boot.
While I was upgrading Fedora 11 to Fedora 14 using preupgrade, I tried to edit /boot/grub/menu.lst file to make an option to continue upgrading the system after rebooting.
Accidentally, I deleted the file content and I couldn't restore it
I knew then that I'll face a problem when I reboot the system, and I faced it >> the grub selection menu disappeared , and only the line (grub> ) appeared when I reboot the system.
1- These commands:
Code:
But when I rebooted , nothing changed and the same (grub> ) appeared again.
2- I used the instructions in the PDF attached, but unfortunately nothing changed.
I think that I have to rewrite the menu.lst and grub.cnf files but I'm not expert and I don't know exactly what was there (locations , commands , etc. )
The current system monitor for the file system is shown in the next image:

9.10 has no menu.lst file and hitting ESC to does not bring up the grub menu. How can we set bootup options or boot an alternate kernel? I would really like to set the resolution at boot time so that my console (Ctrl-Alt-F5, for example) has 80 columns instead of 40. (What a stupid default, gigantic Commodore-64-like text!) It would also be nice if the Login screen could be set to the resolution that I want.
In previous releases, there were ways to do this. In 9.10, I haven't been able to figure out how.
Is there a document explaining all of the radical changes?

So I have been trying for the past 24 hours to get Ubuntu installed on my primarily Windows 7 PC, along with the BackTrack Linux OS, so I can explore things dealing with security a bit more, I decided to Dual Boot into Ubuntu and VMware BackTrack for the obvious reason of I am dealing with Viruses/Hacking and such and would rather do that in a safe environment. So after getting Ubuntu installed and working I now have the Grub boot menu along with 5 options 2 for Ubuntu, 2 that slipped my mind, & 1 for Windows (Loader).
My question is, is there any simple way to get the boot menu for Windows back with it just listing "Ubuntu & Windows 7" as two separate options. Sorry for the small level of incompetence its been about 3 years since I was in school getting constantly refreshed with all the info. EDIT: I should probably mention that if I had just done the install on a new HDD instead of an partitioned external I wouldn't of had a problem.

Like a dummy, I played around with KDE Menu Editor without asking if there was a way to return it to it's defaults, if I screwed it up.
Is there a way to return it to its 'factory settings'?
