General :: Use GRUB To Manage My Dual-boot Startup On PC?
May 10, 2011
On my PC, I use GRUB to manage my dual-boot startup on my PC. Every time I update my Linux, It adds another 2 startup options on my HD for every distro I have. (The Normal and Recovery modes for the new version.) I would like to add the VortexBox distro someday.
Is there a way for me to get rid of the older versions of Linux distro's on my GRUB menu so I just see the newest? I have 6 options for Ubuntu 10.10 and 4 options for UGE 2.8..

I don't know why its called "GRUB 2" while it is actually GRUB 1.98 or 1.99. Anyway.So here's the thing. Due to the fact that I am dual-booting Ubuntu + Windows XP, my GRUB menu would show up during boot with or without me holding down SHIFT. This takes several seconds. What I'd like to do is that GRUB does not show up at all during "normal" boot and only shows up when I hold down the SHIFT right after BIOS POST.

I have a laptop with Karmic Koala in dual boot with Lenny. I need to reinstall Lenny however if I do that I will loose Karmic Koala in the grub screen because of the new version of grub that comes with Karmic Koala. Which means that I will need to reinstall Karmic Koala after Lenny so that they both appear in the grub screen at startup. If I reinstall only Lenny is it possible to use Gparted to change the boot back to Karmic Koala and have them both in the grub screen again? Or is there another way around it?

I have installed a new Linux distro (just to test it) on my usb memory stick, and I'm trying to run it. I don't know if what I did is correct so far, anyways here's what I have:
Grub on sda (internal hard disk)
sdb with no boot loader (memory stick)
In grub I've been doing:
root (hd1,0)
kernel /kernel-genkernel-x86_64-2.6.37-sabayon root=/dev/sdb1 vga=normal
initrd /initramfs-genkernel-x86_64-2.6.37-sabayon
boot
This seems to work (as opposed to when I forgot the root= parameter, which almost destroyed my linux on sda1 ), but during startup the system complains about no root bein found on /dev/sdb1. I also tried (hd1,0), but it didn't change much.
I'm sure I can boot an OS from usb on my computer, so doesn anyone know what I'm doing wrong?

I want to set up grub for a dual boot system of xp and vista. The thing is that I have vista installed and would have to install it ance again after setting up XP in order to use the microsoft bootloader. And secondly I slowly want to get into linux...
This is how I tried it: I have four partitions on my HD and want to install the Bootloader on /dev/sda3. I started up the ubuntu live cd, mounted partition3, opened the console and tried this command line which I found in a tutorial
grub-install --root-directory=/media/hda3 --recheck /dev/hda However I get the following error message:
mkdir: cannot create directory '/media/hda3/boot': No such file or directory

Installing upgrade from Open SuSe 10.3 to 11.3. I did it on a 32-bit laptop, aborted half way through and couldn't get back on because GRUB loader was corrupted. No problem as there are lots of 32-bit GRUB loaders available for download, install was successful 2nd time. I need to do the same for a desktop x64bit dual core Intel. Can't find a x64bit GRUB loader on internet - how do I extract from my current set-up an emergency GRUB-loader CD?

I've run Debian on my laptop for quite some time now with no problems. I installed Slack to a new partition created in the free space of my hard drive, and I thik this was my mistake: I let Slack automatically configure the MBR with lilo (can't remember - I should stop operating on the MBR at 4 AM.) Now Slack runs just fine, but upon bootup I would like to be able to boot either Debian or Slack, but instead I just have a Slack splash and the only option is to press enter to boot Slack.
Code:
I believe sda1 is the root directory of my Debian install.
Code:
In the above table, sda10 is the swap I created for Slack and sda3 is the root directory for Slack. All other partitions were there before (my initial Debian install).
Thus my partitions are apparently intact and visible by the MBR (is it correct that the MBR holds the list of partitions on a disk?) but for some reason I don't have the option to boot Debian at all - just Slack.
I have a feeling this is a LILO/GRUB issue, but I don't know where to start.
EDIT: more poking around seems to reveal that it is the configuration of LILO that is the problem. Observe the following output:

I'm running a dual-boot with linux mint and Windows. I have an E-machines desktop with : 760 GB Hard Drive 6GB RAM NVidia GeForce Graphics card 6150se Integrated AMD Athalon II X2 235e dual-core processor My problem is getting my grub to boot into Linux Mint, and the problem may lie with my graphics card. Whenever I install the linux mint for the first time, I am prompted to activate my proprietary NVidia graphics driver, which I do. Then I am asked to reboot.
Upon reboot, the system gets to the grub menu, accepts my selection to boot linux mint, then the "progress dots" appear on the screen. After about 8 seconds, the screen switches into command prompt mode. I never get to the graphical sign-on screen. All I get is the console sign-on prompts. From there my only option seems to be to reboot. (sudu reboot). After which, of course, I am forced to go into Windows vs. Linux to avoid the problem. Once Windows has loaded up, I do a restart and go back into Linux Mint . Finally, I get to the Linux sign-on graphical screen.
To summarize, i cannot restart linux mint without getting stuck staring at a console screen. I can get back into linux mint if i use the command 'sudo reboot', and, from the grub menu, choosing to go into Windows. From Windows, I then do a restart and end up back at the grub screen again, but this time when I select linux mint, things work and I am given the sign-on gui.
If I choose to not install the graphics driver (and put up with the annoying reminder to activate one), the system dual boots without a problem.

I have been an MCSA for the last 20 years, but recently I have been very impressed indeed with Ubuntu 11.04, having dabbled with and then discarded Susi Linux some five years ago. My problem may be summarised as outlined below: Using the downloadable ISO I installed Ubuntu 11.04 as a dual boot on a Win7 100GB HDD on my Lenovo T61 laptop. No problem they both rock and I'm very impressed. During the installation procedure I selected the largest partition sizes available from the Ubuntu installer wizard being 25GB Extended split into 18GB Ext4, and 3.2GB and 3.2 GB swaps (I couldn't suss out any way of manually increasing them any further).
I found that the 11.04 Startup Manager application didn't work at all, so I downloaded and installed Grub Customizer 2.1..and that did work after a fashion.. certainly enough to actually effect changes in the grub configuration settings. Everything worked so well on the 100GB HDD that I decided to transpose the entire disk image to a new 500GB WD Scorpio and make the dual boot my main working disk. Using Acronis I imaged off the 100GB installation selecting the partition by partition, and retain disk signature options. I then recovered the image to the new 500GB HDD and everything works beautifully on the new HDD.
Except of course all the partitions are still the same size. I won't waste your reading time recounting everything that I have done using Acronis Disk Director (V Good) and Gparted (not so good), but needless to say whatever I do Grub won't have it, and I have lost count of the times that I have re-recovered the good image. Basically I want to increase the partion sizes to apportion larger partitions to both Win 7 and 11.04 and obviously I'm missing something somewhere.
Fdisk -l -u produces..
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x9f011ed1 .....

I apologize for this being somewhat vague but it happened several months ago and I don't currently have access to the laptop. But here goes anyway:Perfectly working dual-boot system with XP and Ubuntu 8.04. I also think I had installed a different boot loader (or maybe just a GRUB editor?). This was several years ago. I upgraded Ubuntu to 10.04 and I remember it asking me if I wanted to overwrite probably menu.lst. I said no when I should have said yes and now XP still loads fine but neither version of Ubuntu will load at all. I wish I had access to the machine so I could say what the error message is, but I don't and I forget.So I expect that menu.lst is just pointing to the wrong place but I'm not sure how to fix it. Can I boot from a live CD and edit menu.lst? Just thought about that.No biggie but I cannot screw up the XP aspect since that's major drama.

I installed Windows XP Pro and RedHat Linux Enterprise 5 on my PC for my purpose. The PC is used by other family members too and they need only Windows OS for browsing. It is becoming problem for them to reboot after the PC enters into Linux by default. I am still learning Linux and I want to edit the /boot/grub.conf file to make Windows as default OS to boot. The following is the content of my grub.conf file (FYI):
#boot=/dev/sda
default=0
timeout=10
splashimage=(hd0,5)/grub/splash.xpm.gz

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?

HW config is: AMD Athlon 64 X2 5000+ Black Edition, MSI 785GTM-E45, 2X 1Gb Kingston HyperX PC2-8500. I have set up GRUB to dualboot openSUSE 11.2 and WindowsXP. Initially i had set up system with defaults: CPU@2600MHz (200X13) and therefore RAM@800MHz. Both openSUSE 11.2 and WindowsXP worked just fine. Memtest86 found no problems.
But after a while i decided to change this setup to: CPU@2500MHz (250X10) and therefore RAM@1000MHz, as it promised better overall performance. And now Windows still boots and works better then before. Memtest86 still can't find any problem. But openSUSE 11.2 hangs at boot. I've suspected cpufreq governor, but changing from Ondemand to Conservative in /sys/devices/system/cpu/cpu0/cpufreq doesn't help.

I'm trying to dual boot Win7 and Ubuntu WITHOUT using Grub. This is to support Bitlocker encryption.
I followed this guide, and now when I select Ubuntu I get a Grub> prompt and no ubuntu.
I feel like I'm halfway there, I just need to get Grub to load correctly or something.

I've installed Ubuntu on my new desktop alongside Windows 7 (each OS is on a separate drive), I seem to have run into a small problem. Let me start with what I did:
- Unplugged 1TB drive from the PSU, BIOS was not seeing my formatted (and thus empty) 500GB drive and I couldn't put it into the boot order at all with the 1TB turned on.
- Loaded up the boot CD and was able to install Ubuntu 10.1 on my 500GB drive.
- Did a bit of configuring, shut my PC off and plugged my 1TB (with Windows 7) drive back in. I tried to see if I could now see my Ubuntu drive in BIOS but nothing is there - just the Windows drive is in the list of available drives to boot from (along with DVD-ROM and USB).
This is where I've run into my problem. What I want is to have a nice GRUB boot menu at the start like any other dual-boot system but just have the two operating systems on separate drives altogether.I did it this way because I was having issues with the advanced partition menu on the boot CD so just went ahead and followed the KISS method by unplugging the Windows drive.
I was told by a friend that if I put my Ubuntu drive into the first position in my boot order and the Windows drive in the second, then I could boot into Ubuntu and run a GRUB update command (he told me to google it) and that would create the necessary GRUB that had the entries for Windows 7 and Ubuntu.Both operating systems are 64-bit, I imagine that might make a difference in whatever help you guys can offer me. I love the hell out of both OS's and want to be able to use them interchangeably.

i am having a problem with my dual boot setup. I originally installed windows XP on a 100gb hard drive, from there i downloaded and burnt ubuntu off so i could install it on my 200gb hard drive. For a little bit i struggled to even get it to install because it wouldn't recognize my onboard nvidia graphics, i ended up having to get an alt boot disk and fix it with technique in this link:

Now after the bios boot, my screen shuts off for awhile and takes me directly to the login screen for ubuntu. No Grub, no windows boot options, nothing. I tried booting windows by choosing it from the bios boot menu but all it does is hang at prompt and doesn't boot at all. I tried the live cd fix and reinstalled grub but nothing changed. What i think is happening is that it boots the Grub menu but it doesn't display it because of graphical confrontations. It hangs for about 10 seconds, the grub default time, and then turns my monitor back on to display the Ubuntu login screen.

I followed a tutorial to install XP across my entire HDD. I installed Ubuntu 10.10 "Alongside another OS". Ubuntu loads fine, but when trying to load XP, the boot screen shows up, but then the computer restarts and returns to the GRUB menu.
I saw some threads on this site and tried to type: sudo gedit /boot/grub/menu.lst
In the terminal. It returned a blank text document so I'm not sure if that information was outdated. I then typed: sudo fdisk -l
And got this:
Not sure what any of this means, but I sure hope someone else does. I would say forget XP, but it's hard to let go of some of the games and software I use. I appreciate any responses, thank you.
I tried to format the table as it appeared, but the forum corrected the extra spaces.

This is the third time I try unsuccessfully to install Debian as a second OS on a hard drive. When it gets to the end of the installation process the installer asks whether I want to go ahead with the Grub Boot Loader, I choose yes. The end result is however that I can't boot that partition within the hard drive -- i.e., Debian. Can someone tell me what is going on? Should I not use the Grub Boot Loader when I have more than one operating system on a machine? Should I not install Grub on the Master Boot Record (MBR)?

I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).
I installed grub on the Fedora disk so as to not touch the windows disk at all.
Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)
My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?

I had a dual boot system with 3 partitions, Windows 7 on one partition, and Windows XP on another partition and a Data partition. I decided to load Ubuntu 10.10 on the Windows XP partition.During installation I selection manual partition, and deleted Windows XP.after successful completion of Ubuntu installation "Grub" directly boots into Ubuntu, it doesn't show me the OS selection screen. After following some forum posts I did an update grub
Code:
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.35-22-generic
Found initrd image: /boot/initrd.img-2.6.35-22-generic

I updated from Ubuntu 9.10 to 10.04 via Ubuntu updater. Worked nicely. Until I had to use Win 7 for a moment, so I went to the Grub boot menu and picked Win 7. Nothing is happening. Just a black screen with blinking underscore to the top left corner. I never had this problem with 9.10, so I am confused. I tried looking around and nothing helped. Be noted that I am an amateur with Ubuntu coding and installing. I did hear that this is already a common issue now.

Ubuntu 9.10 was set up to handle the booting selection - previously I thought it was xp but Ubuntu 9.10 "did" it. The system started out as a xp / ubuntu 9.10 dual boot on a 400gb drive. xp has 210gb, ub has 80 and their is a 100gb shared storage. Xp was installed first and then I followed a guide over at linuxconfig.org to get ub installed so that I could select which OS was wanted at boot. Ubuntu manages the boot up menu (Went back to look at my notes from the original setup) The owner tried to update to ub 11.04 and afterall was said and done the machine now boots to the message
error file not found grub rescue I can't say if 11.04 was properly installed or not. Ask whatever you like and I'll give the best answer I can. I think the xp install is okay but I can't say for certain as I don't know how to boot it outside the bootmanager at startup. Data has been saved so if I have to blow it all away and start over I can but I'm hoping I won't have to.

I've recently installed Vmware on Vista and I am using that to run Linux. I prefer this method over duel booting as I can quickly switch between the two OSes. So here is what I would like to do.
1) Remove swap partition (not needed).
2) Remove Linux and format partition to NTFS for windows use.
3) Remove Grub.
What I don't want to do.
1) Reinstall Windows Vista (Lots of programs installed).

I have Windows xp and Ubuntu 10.04 in my system and last fine morning I was working in windows and when I restarts the system as there were some problem in the audio I found that the grub is not loading. Computer boots directly in the windows xp mode and not giving the possibility to boot in the ubuntu OS. Also, the windows xp restarts continuously with a blue screen for just a second.
This happened out-of-the blue. What might be the possible reason for this and how to get rid of this problem..

I am running a dual-boot of Ubuntu 10.04 and Windows 7. My current setup uses EasyBCD to pick between Ubuntu and windows. If I pick Ubuntu, it then fires up GRUB, which then goes to Ubuntu. My question is: Can I skip GRUB altogether in the boot process? I rather suspect that it's slowing things down a lot. I've set the GRUB default OS timeout to 0, but it still boots slowly, which annoys me. way to skip GRUB entirely and use only EasyBCD for both OSes?

I CTRL ALT DEL and it reboots back to GRUB2 and I select UBUNTU and I log in. This is the first time I have tried to reboot Windows XP after fresh install of UBUNTU
