Ubuntu Installation :: Grub 2 Missing In Action ?
Feb 13, 2011
After a hard drive failure I installed Ubuntu 10.04 LTS in the secondary drive. The intention was to have keep the machine functional until I could reinstall XP and have a dual boot. I replaced the failing drive and reinstalled XP.
The main reason for keeping windows is for using Itunes and a ton of music on the Ipod. I can get into the Ubuntu using Super Grub2 and did try repairing Grub 2 with rescutux. I can of course use the super grub2 disk to boot into Ubuntu but would like to repair Grub2 so I have the choice at boot without the disk.
Here is the readout from the boot info script.

I'm running Hardy 8.04 LTS 64bit. The Update Manager updated the kernel and then asked if I wanted to use the local version of the grub menu. The boot menu was getting so long I edited it to shorten it. Other options were also offered, like the builder's version, but I chose the local version and since then the new kernel doesn't show up in the boot menu. Sudo update-grub doesn't restore it to the menu.
How do I undo the local version of the boot menu so I can see the newest kernel?

I had a dual boot system(WinXP and Ubuntu). But something happened and I was not able to boot into my Ubuntu partition. It gave GRUB missing error. I tried reformatting the dedicated 40 GB ubuntu partition to NTFS and again try to reinstall ubuntu. But now, when I install ubuntu through boot time install, it shows that my whole hard disk is empty( but I have windows XP on whole hdd at the moment) and do not give any other option but to use whole hdd.
Alternatively when I try to install it inside windows, then after rebooting it shows, no root file system defined error and neither gives any option to do so also ( this method worked earlier o my PC). At the moment, It still shows ubuntu and windowsXP at OS choice menu at boot time but when booting in ubuntu, it shows GRUB missing. (I don't have any ubuntu installation on my hard disk at the moment).

Had v9.x installed alongside Windows XP SP3 install. Have not used it that much since install.
Got the bug to upgrade to v10.
Went through the upgrade process, everything seemed fine.
At the end of the install process asked which dev to install GRUB onto - I selected only one drive, the wrong one of course, and the reboot failed.
Boots up with:
Have LiveCD running now to post. Ran Info_boot Script.sh - results below.
Will reinstalling v10 from Live CD fix this? Will this use Wubi or just go through normal install process? Or is there an easier fix to install GRUB on the correct drive to get the dual boot choice of Windows XP and Ubuntu back.
Naturally I need to get back to Windows ASAP - it's the net gateway and print server for my home/office setup.

I had Ubuntu installed. I partitioned my drive and installed Windows 7. After that grub was missing. Following the directions I was able to fix that problem.Now when Ubunutu 10.10 loads up it says failed to find /home wait or press S/M to skip or fix.I went ahead and hit M... I'm not sure how to fix the /home problem. I know /home is on it's own partition, but I'm not sure how to fix it

I have installed windows 7 back to its former state in after foolishly messing around with some installation options in an Ubuntu install (this caused windows to disappear, and me to repair it). In *repairing* windows, I overwrote my grub file and the boot options for Ubuntu, so that it looks something like this:
Disk 1: Primary Partition - Windows 7
Disk 1: Secondary Partition - Windows 7
Disk 1: Secondary Partition - Free Space ( this is where I have Ubuntu installed)
How can I repair my grub file so that I can boot into my Ubuntu installation?

I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.

The update package popped up with some security updates. I downloaded all of them and then hit the restart button. Now all I see after the winboot load is the grub 'dos' screen. I can get to grub rescue but thats it. I was wondering if there is a way to download the missing files from somewhere and place them in the grub folder as I am dual booting with XP.
I have installed Ubuntu onto a seperate partition as well.

Windows 7 wont start from the GRUB menu. After selecting the windows 7 entry I added to my '/boot/grub/menu.lst' i get an error saying BOOTMGR is missing. Both windows 7 and fedora 13 were freshly installed just yesterday. Win 7 first on one HD, fedora on another.
Heres some info:
Code:
Ger�t boot. Anfang Ende Bl�cke Id System
/dev/sda1 * 2 26762 15360000 83 Linux
/dev/sda2 26762 35682 5120000 82 Linux Swap / Solaris
/dev/sda3 35682 126504 52131840 83 Linux
[code]....
Windows is installed on my 200 GByte HD, sdc1 - and since Fedora is booting from sda1 and the menu.lst says root (hd0, 0) the windows entry should look like root(hd2,0), no? I tried a couple of different variations of my menu.lst, but i always got this BOOTMGR error. I read that mapping is not needed since vista, is this true? i can only enter the GRUB menu after hitting escape on start up, is there any way how i can have it starting the menu automatically?

The problem after couple installations (10.10 --> 10.04 --> 10.10 --> 10.04-3) is that system goes to "busybox" after complaining about missing root device. I already have come to conclusion that this problem could be solved by telling the system that the root device is at sda1. However, I'm not able to start grub (by pressing "ESC") at boot before problems start. I'm able to start live-cd and I tried to install "over" the old one (same partitions without format, same username). No luck.
And in the busybox /proc/modules is empty for example. And the grub has worked with previous installations.

I just netinstalled Squeeze to a netbook with Windows7. The installation went well without any problem. Linux is also working OK. When I boot now, grub does not show Windows7. I took default settings during installation. I mean I did not do anything special. What should i do to fix it? Should I run osprober and grub-update?

I am a brand new Ubuntu user that just tried to install on an old PC using the 10.10 desktop edition.During installation, I hit an error that the bootloader could not install, and after reading about it on the forums, opted to attempt to install it manually after. I have followed the tutorial located here,[URL].. on reinstalling GRUB2 from the liveCD, which I assume means to boot with the installation CD and select try Ubuntu (given the only other option is install, which I have tried twice) everything up to step 5 in that tutorial seems to run successfully, and I am given a message it is installed, but then when I reboot the system it does not open the GRUB2 menu, rather the CLI interface, which suggests there is no grub.cfg
So I am unable to refresh at the GRUB menu because that command is not recognized by the CLI (and it may not help if I am missing files, so I might have screwed up reinstalling them in step 5, or maybe the "Try Ubuntu" terminal doesn't alter the computer like I thought?)

I installed lilo and it boots. How do I installed grub again. Do I just use synaptic manager to uninstall lilo and install grub?
[code]....
I know grub2 does not work, giving me error: ntoskrnl.exe missing or corrupt. I did install grub-legacy and it worked, but I had to re-install squeeze due to other problems. So, now I want to replace lilo with grub legacy.

I've had Windows 7 installed for a few months now and would like to install Fedora 12 on a separate partition. I've tried this three times now, all of them ending with something wrong. The problem that exists for me now is that when I install Fedora 12 and boot up for the first time in GRUB, Fedora 12 works fine. ut when I boot into Windows 7 from GRUB, it just comes up with a black screen and says "BOOTMGR is missing; press ctrl + alt + del to restart" at the top. I don't believe that GRUB is booting into the wrong partition because I have no Windows recovery partition, just Windows 7. Also when I try and fix the Windows 7 partition with the system recovery disk, it says that the volume is corrupt every time. At this point I have everything backed up on a separate drive so I'm open to try installing Fedora 12 again even if it risks screwing up my Windows 7 partition, I would really just like to have a functioning dual boot.

Whenever I do sudo apt-get or use the Ubuntu Software Center, I can't download anything because a message comes up saying "Action requires installation of untrusted packages: The action would require the installation of packages from not authenticated sources." I've been trying to download GIMP and Thunderbird, so... I dunno what the problem is.

I want to install slackware (i.e. dual boot) along with ubuntu 10.04. I've read some threads as to how to do this and came to know that we need to skip installation of LILO in slackware installation and an entry for slackware in the menu.lst file of grub. I thought I'll take a look at the file before I actually start the installation however I didn't find this file at all in the grub directory.Can someone please tell me if it is normal for this file to be missing or is something wrong here? if there is something wrong then what do I do

I had Windows XP installed, then installed Ubuntu 9.10 in a different partition. I was able to choose which OS to boot. Then I did a distro update to 10.04. Now Windows is missing from the GRUB boot menu.
sudo update-grub doesn't change anything so I think sudo os-prober isn't finding Windows.
I've edited grub.cfg and can get an entry added for Windows, but it doesn't actually load Windows. It just reboots the machine. If I run sudo update-grub after adding a menuentry for Windows to grub.cfg, the menuentry I added disappears.
I've run testdisk, but BackupBS isn't an option. It says the original and backup boot sector are identical.
cfdisk says sda1 is the only partition that is NTFS and it is set to Boot.
I've already installed all available updates from lucid-security and lucid-updates.
I've run bootinfoscript and here are the results:
Code:

Today I tried to boot up Win 7 but it appeared "BOOTMGR is missing" error. I boot from windows dvd, selected repair but it didn't found my windows install. I have to use rebuildbcd - didn't work, then mark my partition as active - I figured out that it was active and I marked it as inactive and now grub is also broken and I'm using live cd.
