Ubuntu Installation :: GRUB Menu Is Showing Two OS's ?
Sep 12, 2010
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 reinstalled Natty yesterday and then installed Fedora on a separate partition.
I now havedouble the menu items in GRUB2 for both of these.
I ran the update grub command in the terminal and it goes smoothly, but the extra menu items still don't go away.
Puzzingly the menu items point to the same partition on the drive as their clone. Both of the Fedora menu items point to sda8
For example.
tl;dr:
How can I remove menu entries in GRUB? I searched but could not find a reliable answer other than re-running update-grub.
How could I remove GRUB and replace it with Plymouth? Ubuntu Software Centre actually shows Plymouth as "Installed" even though it does not run on startup.

When I first boot up. I get the GRUB command line. What happened to the boot menu? And I can boot up into my Windows partition just fine. But when I try the other partitions i get "Unknown file system" or when I try to boot into the other ntfs drive, I get "BOOTMBR missing", but yet it does not mean Windows, because i can boot that just fine. I can't find my Ubuntu partition. How can I get the GRUB boot menu back?

I am working with a acer netbook that I originally had WinXP installed on. I downloaded Ubuntu 9.10, transferred the iso contents to a bootable USB drive and installed Ubuntu. I remember during the setup process that I made sure I chose the option to install on one partition. There is only one partition on my netbook with a small second partition as a swap.
After the installation process and reboot I noticed the grub menu would pop up every boot up giving the list of operating systems of which XP was included. I then ran the update manager and updated 9.10 with all updates. After rebooting the grub menu again showed but the option to choose XP was now gone.
Now everytime I boot up the grub menu shows. How can I modify grub so it will automatically just boot to the OS.

I have a computer that only runs ubuntu and have decided to put fedora on. I put fedora on the computer and made a new partition for it. When I turn the computer on, it logs straight into fedora not even showing me a grub menu. Is there some way that I can update grub so that it knows that ubuntu is also installed

Last week i decided to give the 11.04 alpha 2 a go on my laptop but compiz is currently too unstable for the OS to be of any use so I reinstalled 10.10. In doing this I deleted all partitions and started completely afresh. Strangely since then I have kernel image 2.6.38-1 at the top of my grub menu but if i try to boot it i get either a single blinking cursor or a kernel freeze. I cant find any reason why 2.6.38-1 should be in grub on 10.10.
removing it from the config files as im not used to Grub2 and have been told i cant just directly remove it from /boot/grub/grub.cfg.

I have a National Instruments gpib interface PCI card on my machine. It has been working up till now.The computer was moved when I was gone, and now at start up I get two alarm beeps from the motherboard speaker, no grub menu (hidden line is commented out and time out is gtr than 0).In the past I had to lock the kernel to 2.6.32-28.55.newer kernels broke the interface...although prolly foolioshly, I did allow other system updates.

I just installed ubuntu 11.04 via wubi. the installation appears to have gone well but ubuntu doesnt appear as an OS choice when i boot up.
Its not a timeout issue as it is set to 30sec and i can see my other options (windows and a recovery option). the only thing i can think of is that my computer has a separate partition set up for recovery and i think that is screwing things up.
Here is my boot.ini:
My only guess is that since the recovery partition is the first partition that its causing problems.

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 just installed FreeBSD 8.1 on /dev/sda4 (FreeBSD slice), without installing the boot loader from FreeBSD (I've selected None when prompted for boot loader in sysinstall). Now I want to use my existing Grub2 from already installed Ubuntu 10.10 to boot FreeBSD also.
After some reading, I've added to the end of /etc/grub.d/40_custom:
After running sudo update-grub, grup.cfg file shows my new entry. The problem is that after restart, I don't see the new entry in the grub menu.
Another question, If i used chainloader +1, that means I need to have the FreeBSD bootloader installed also on /dev/sda4 right? For chainloading booloaders?
I didn't get to that step, I first want to see the entry in the menu.
Any idea what I might be missing/misdoing? (I also checked for blank spaces in the menuentry like the wiki for grub2 says)

I have both 8.10 and 10.10 installed on my hard drive, but whenever I boot the GRUB (I believe it is GRUB Legacy not GRUB2) only shows 8.10. Is there any way to get it to see my newly-installed 10.10?

My laptop came with Vista and I added Linux Mint 6 (based on Ubuntu 8.10 Intrepid Ibex) all is good for a year or so. Added Ubuntu 10.10 to my desktop, loved it, wanted to add it to my laptop...oops.
Installed the main version from a LiveCD, did the the easy multi-OS installation.
GRUB-0.97 is what boots my system though looking at boot script I do have GRUB2 somewhere.
Currently, my boot options are:
1. Mint 6
2. Mint 6 (recovered)
3. Mint 6
4. Mint 6 (recovered)
5. memtest 86+
Other operating systems
6. Vista/Longhorn loader
7. Vista/Longhorn loader
Sda7 is where Ubuntu should be installed. GPARTED says its ext3 file system and bootscript says ext4.
I did find the forum post on purging and installing GRUB2 though I'm not sure if that's what I need to do, or try to reinstall Ubuntu w/o also doing partition resizing at the same time.
The output from my bootscript:
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive in partition #5 for /boot/grub/stage2 and /boot/grub/menu.lst.

I bought a new NVidia Asus EN210 for my HTPC, but I can't get Ubuntu to install.
First I made a live USB disk of 10.10 with Unetbootin and when I choose the option of "try Ubuntu" it starts loading and then just hangs, still showing the menu of boot options. After this I tried Xubuntu on a USB disk. This one also starts loading but then just fails. I also tried XBMC Live. This one does show the Ubuntu 10.04 screen but then just shows a black screen.
After this I found a CD with Ubuntu 10.04, I think or it is 10.10, laying around in my room. I booted it and once I select an option from the install menu it starts to load, but then just gives a black screen with a flashing "-" sign.
The strange thing is, once I pop in the old video card, which is an ATI HD4350, my Ubuntu 10.10 Live CD on USB disk does work and it does get past the menu of boot options (in my second paragraph I describe how this isn't the case with Ubuntu 10.10 combined with my NVidia card).

At first I thought it was a fluke, but it happed on another computer I was a bit late in updating. I'm running 10.04 lucid 32 bit on both computers.
After running the update, everything ran fine. The script ran update-grub and everything seemed ok. However when I rebooted, my laptop booted into GRUB and only showed windows and the recovory partition. Desktop would boot strait into windows with no selection (I knew how to fix it for the desktop since it happed a few days later)
When it first happend on my laptop, I scrounged around trying to repair the OS list, but nothing worked. Eventualy running "grub-install" with the "--root-directory" option on a live CD fixed it.
I'm not sure what is causing the problem, but I think I remember there being an update to GRUB when I ran the updater. The fix works, just a bit of a hassle, but I thought I would bring it to someone's attention in case it happens to them.

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 installed Fedora 14 alongside windows, overwriting my old Ubuntu 10 partition. Unfortunately, now the GRUB loader only recognizes my Fedora partition and the built-in windows recovery utility partition. I checked the disc utility and my windows partition still definitely exists, I just can't seem to boot into it.

I installed Windows 7 and then Ubuntu 10.10 64 bits. The Ubuntu installation went fine but when rebooting a "check disk" appeared and since then my PC keeps booting directly on Windows. I tried all the GRUB reinstallation methods of the GRUB2 Community Documentation with the live CD but none worked.
Below is the output of the Boot Info script found on several threads.

I was upgrading from 10.10 to 11.04 with terminal. When terminal asked about mime.types (it asks what to do with it) I chose showing me the differences between the new and the old versions. and then I couldn't get out from the "showing differences menu"! so, I shut down the terminal. and now I'm afraid to reboot the computer. can someone possibly say, what i am to do next is it okay to reboot my computer. or do i have to do smth first? Oh, and i almost forgot, when i sudo do-release-upgrade i says that i have latest version and doesn't do anything. update manager isn't showing up neither

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.
