Ubuntu Installation :: Extra OS Listed In Grub Menu?
Jun 25, 2010
I have a extra OS listed in my grub menu. I'm dual booting Ubuntu 10.04 and Windows 7. I am able to boot into both Ubuntu and Windows. 30_os-prober has two menu entries for Windows though. The first one is Windows 7 (loader) (on /dev/sda1) and the second is Windows Vista (loader) (on /dev/sda2). My laptop came with Windows 7 and had 4 primary partitions (System, Windows, Recovery, HP_TOOLS). After making my recovery disks I removed the Recovery partition and shrunk the Windows partition to make space for Ubuntu. So Windows 7 (loader) (on /dev/sda1) is the System partition which I select to boot Windows. Windows Vista (loader) (on /dev/sda2) is where my Windows 7 is installed. Here is output from Boot Info Script:

I'm running Ubuntu 9.10 dual booted with Windows XP. Ever since I installed 9.10, I get a long list of OS's (actually, multiple repeats of what appears to be the same Ubuntu install), and I can't get rid of them.I've looked through various tutorials and the GRUB 2 Community documentation (https://help.ubuntu.com/community/Grub2) but I still can't get rid of the menu items.I edited the 40_custom file and was able to add the entries I wanted to see, and then chmoded 644 all the other files in the /etc/grub.d directory and run update-grub.The custom entries do appear at the end of the menu now, but the old entries are still there as well. This is what I get when I run the update-grub:
Code:
yoodle@HANSOLO:/etc/grub.d$ sudo update-grub
Searching for GRUB installation directory ... found: /boot/grub

I recently installed Fedora 14 on an old Dell server (Pentium 4). It works fine, except that it somehow includes an extra startup step, in which I have to choose between two different grub versions. Here is the screen I get:
GNU GRUB version 0.97
Fedora (2.6.35.11-83.fc14. i686)
Fedora (2.6.35.6-45.fc14. i686)
Press enter to boot the selected OS, 'e' to edit the commands before booting, 'a' to modify the kernal arguments before booting, or 'c' for a command-line. I always select "Fedora (2.6.35.11-83.fc14. i686)" because I presume it is the latest version. Is there anything I can do to automate the choice of "Fedora (2.6.35.11-83.fc14. i686)" and avoid this extra step? On another subject, I have already modified the custom.conf file to eliminate the login screen step.

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?

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've triple booted Windows 7, Windows XP, and Linux Mint 9. I can boot to Windows XP, and Mint with no problems, but there's no Windows 7 option in the boot menu. How can I get Windows 7 to show up so that I could boot to it?
I tried sudo update-grub, but Windows 7 didn't show up.

After cheering the Ubuntu Developers team on the great work they did with hardware recognition, I was suddenly stunned by the silence from my USB speakers this afternoon. Although previously correctly recognized and fully functional, after installing several non- audio updates, the sound from my USB speakers ceased.Moreover, this pair of Logitech Z-5 USB speakers aren't even listed on the Sound menu (System > Preferences > Sound) although lsusb lists them correctly. I have an embedded sound adapter to which no speakers are connected. My PC runs on Ubuntu 10.04. What should I do to get the sound through my USB speakers?

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

1: In my grub menu Windows 7 is listed, I don't know why. Win7 was installed on this computer before,but I formatted the HDD before I did a clean install of Ubuntu 10.10. How to remove it?
2: When I boot I don't get a boot image, only a blinking cursor in the upper left corner. Not a big deal, but I would like to have a normal boot image. Any ideas how to fix it? I tried googling but I only find old threads. My laptop is a Acer Aspire 7735Z
Graphic card is ATI Radeon HD 4570. BTW; I got no other problems what so ever. Everything works great really.

I recently installed ubuntu 9.10 and a day later updated with all the suggested security and recommended updates. Now I notice that in my Grub there are two different kernel versions listed. Are they both necessary? Can I / should I get rid of the older one, and if so, how?
I ask because after all these updates I notice my computer runs much slower, so I don't want it overloaded with unnecessary software.

I have a dual boot desktop with WinXP on C: and Ubuntu on D:. GRUB 2 handles the start-up. Having installed multiple updates to Ubuntu, my GRUB menu now lists:
2.5.31-19-generic
2.5.31-17-generic
2.5.31-16-generic
2.5.31-15-generic
2.5.31-14-generic
and (recovery mode) for each of the above, along with the mem test and WinXP.Is there any reason I need to list all these variants of Ubuntu? If not, can I simply edit them from the GRUB config file or must I do something else to actually uninstall them?

I recently upgraded to 10.04, but it gave me a heap of problems, so I've reinstalled 9.10. Everything seems to be working again, but Grub seems to think that the 2.6.32-24 kernel is installed.When I try to boot it, it gives me a ton of errors that basically say it can't find what it's supposed to mount, so I'm assuming that it's left over from Lucid.Thing is, I can't find the kernel in synaptic to uninstall it, but when I update grub, it still lists it as being there.

MPlayer was working just fine last night, but today I'm having problems which may be due to me performing a system update. I noticed that MPlayer was no longer listed in my Applications menu and I no longer had the option of opening videos with it. However, I now had Gnome MPlayer which must have been installed with the update because I never installed it. Whilst going through Synaptic, I found that the MPlayer GUI had been removed, so I re-installed it. However nothing happened when I attempted to open videos with it.
When I tried to use it through the terminal I got the error message:
mplayer: relocation error: mplayer: symbol codec_wav_tags, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference
I found a bug report on this very problem here [URL]. The conclusion was that the person filing the bug report was using a version of ffmpeg not found in Debian and that he'd need a version of MPlayer built with his version of ffmpeg libs. I'm assuming that this is also the case with me, however I'm not sure how to go about finding a build or simply building a version of MPlayer with whatever version of ffmpeg that I'm using. For reference, I'm using Squeeze.

single hdd
/dev/sda1 = 100mb Windows7 boot part
/dev/sda2 = Windows7 part ( encrypted w/ Truecrypt)
/dev/sda5 = /boot Ubuntu 10.04
/dev/sda6 = / Ubuntu 10.04
Truecrypt bootloader is in the MBR
The Truecrypt bootloader will boot other loaders if esc is hit, I can choose to boot /dev/sda5 and grub loads, but no menu is displayed, all I get is a GRUB> cli. I've reinstalled Grub to /dev/sda5 using the chroot method outlined in the Grub2 info page on this site, but it always results in the same outcome of ending up in the Grub cli. I can chroot that install and attempt a update-grub, but all i get is "cannot find list of partitions!" attached is the boot_info_script results.

Once upon a time I had Maverick Meerkat installed on two drives. Now I've used Disk Utility's "Format Drive" to erase it and remove the Master Boot Record partitioning on one of them. Yet I still have to go through the GRUB menu each time I start up my computer, as if there are multiple bootable drives. I've read that 'sudo grub-install /dev/sdb' might work, but that only seems to reset the bootloader, not remove it.

I have an external USB drive with Mint9 Fluxbox installed on it. At one point, I wiped the drive and set it up using GPT instead of MFT, then partitioned the drive in GParted and installed the OS.
This setup was working fine, but now I have a new laptop, and the OS won't boot. I just saw the errors, "No such partition: UUID=xxx", "Could not find kernel, hit any key to continue". So I attempted to reinstall GRUB via terminal, but saw errors saying that GPT requires a grub_bios partition. So I made a 1mb partition at the end of the drive, (the only unallocated space without moving anything) and selected the grub_bios flag.
I was then able to reinstall Grub without incident, rebooted, selected the USB drive to boot first in bios, but still no Grub menu!?! It just boots from the next device in the bios list.
I'm currently using Crunchbang on a USB stick, which is where I'm running terminal commands from. I want to be able to boot from my external drive on any computer.

Ever since the intro of Grub2, on the main Log-in screen, there is a "User" listed at the bottom of whoever is listed on the Users Log-in. Just what or who is this used for?. If it is 'clicked' on, then it asks for a password, as if 'it' is some kind of "user". But, as I don't know just what 'it' is for, therefore I also don't know 'its' password either.

I am using kubuntu 9.04 dual booting with winXP. The package kit showed that I have 179 bug fixes. So I updated them.Now the boot time grub menu shows 6(two different versions for kubuntu and kubuntu recovery mode) entries instead of usual 4(winXp + kubuntu + kubuntu recovery mode + memtest). My grub.cfg file is as follows:
Quote:
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub

What is wrong. How can I change the entries. Which one to remove ?

I have dual-booted Windows XP and Ubuntu. Because Ubuntu 10.04 doesn't have the required proprietary drivers for my system, I chose Ubuntu 8.04. The installation procedure went well, the drivers are there, everything's perfect but... there's a problem with the GRUB menu that appears just after launching my laptop.
When I first installed Ubuntu it showed Ubuntu (and some letters and numbers), another instance for recovery mode, some memory test lines (I guess there are two of them) and Windows XP.
But after I used the software updater in Ubuntu (to make it up-to-date), the grub bootloader shows two more lines - and those are the same as the first two - Ubuntu (with some letters and symbols) and Ubuntu recovery mode.
Why are those duplicates there? I've never installed another Ubuntu OS on my PC. Because at the moment I have two Ubuntu and two Ubuntu recovery mode lines .

I've done a clean install of XP Pro on my HP XW8200 (Boot drive is 2x73GB SCSI drives set up as RAID 1)I've run the Ubuntu 10.10 desktop installer and partitioned the drive, installed ubuntu and rebooted when requested.No OS selection screen appears after POST though. Just goes straight into WinXP. The startup options in XP only show XP.Rebooted from the Ub10.10 live cd and checked that the partition is there and the OS files are there.
Any ideas why the grub menu doesnt appear?I'm assuming it's something to do with Ubuntu not seeing the RAID drive but it did install ok..

I've installed 11.04 on my laptop (dual boot with Win7). It goes through the grub boot menu and boots in ubuntu but displays ~inch wide band near the top, nothing else. I assume it is a display issue (it has an ATI mobile Radeon HD 3870 X2 card) but can't seem to resolve problem. I can boot into Windows via the menu. In the grub menu I can boot into the command line (grub>) but can't seem to make progress beyond that. Within this grub interface, it won't take terminal commands.
