Ubuntu Installation :: How To Multiboot Using Grub2 (SuSe / Fedora And Lubuntu)
Apr 3, 2010
I am desperately looking for a how to : multiboot. Checked bodhi.zazen's thread, but its totally with reference to GRUB Legacy. I have karmic installed and also vista. wondering if there is a step-wise guide to multiboot with reference to Grub2. I want to add a SUSE, Fedora and Lubuntu, but have no clue as to how. I messed up my comp earlier trying to multiboot so now I just dual-boot Windows Vista and Karmic Koala.

I just installed lubuntu 10.10 onto my desktop and while on my first bootup I had the option to boot windows through grub, it's disappeared from the boot menu since then.When I installed I created a partition for lubuntu and installed onto that. I can still access and see my windows partition.

Don't know if I should have posted in Ubuntu specific section but since it involves grub2 and a quirk in my bios, I have attempted to multiboot 3 Windows versions and the problem I had was intalling a second Ubuntu. (Don't ask!) I had success multibooting with grub legacy on an older computer but this computer has a tricky mb which won't let me install grub to the second drive on an IDE port. What I mean by this is that since I already had boot files to the older drive in mbr- it won't allow me to install to mbr of the other drive in IDE port even if set first in bios boot order, my old computer allowed me to do so, exept perhaps its because 2 HDD were SCSI... (I have other HDD installed in RAID 0 on the other sata ports supported by mb (fakeraid) but I will use these for video editing as scratch disks later. One other HDD used for data is on the Raid port but not in an array).
I succeeded in installing Ubuntu desktop only after realising that I had to first switch my disk order in bios- otherwise the system would just hang. U. Desktop grub had sucessfully found Win bootloader links to both XP and Vista. I then installed Win 7 and used easy BCD and grub2 boot entry to link back to my Ubuntu Desktop grub 2 menu.
The problem occured when installing Ubuntu Studio ( for which I created a separate /boot partition) and I decided to install grub2 to mbr since it had correctly detected all my OSes! But then it seems it never installed correctly to the mbr. I still had Win 7 BCD bootloader in MBR! I tried to link easy BCD boot entry to the /boot drive but that didn't work and I ended up having to reinstall Win7 because I had overrid the BCD with faulty neogrub mapping entries- which I then removed and kept the orginal neogrub that still points to Ubuntu Desktop grub menu.
I also now realise that because I installed Ubuntu Desktop before I switched the HDD boot order in bios- U. Desktop's grub.cfg sees root of Desktop grub differently than neogrub BCD does root=(hd4,7) vs multiboot kludge (hd3,6) and at first I tried to install grub in the wrong hdds and partitions- I based mapping on neogrub's to find /Boot (hd3,2) and (hd3, 1) which is wrong!
What I am attempting to do now is to chainload grub2 from my Ubuntu studio located in /Boot with what I thought was the right mapping but still no success:
menuentry 'Chainloader' {
insmod chain
set root=(hd4,2)
chainloader +1
}
yielded error: hd 4,2 cannot get C/H/S values press any key to continue, also when in terminal in Ubuntu Desktop in
grub> find /grub/core.img
Error 15: File not found
I will attach Boot_info_script; at this point I am too tired and afraid that I will keep on installing grub to the wrong drive!
Note: I somehow got a problem loading into XP after all these failed attempts and a system 32 file seems to have gotten lost-haven"t attempted to fix yet. Just wondering in passing what happens if I chainloaded into Windows by error- if that could have corrupted it? Right now 3 out of 5 OS are bootable. I hope I can repair it without messing up my mbr again. Another issue is that some devices are on busy IRQs and then suddenly its resolved and my onboard LAN suddenly stops working at times so I don't know if any of this could cause XP to get stuck at loading screen.

I got a PC (32 bit) from my friend that has Fedora & Ubuntu on single HDD. Now I need to install Suse on the same HDD without destroying other distros. What are the prerequisites for this? & how to do this step by step. I'm not sure how the before installation is done?? I'm not sure about grub editing/tweaking. At present installation of SUSE is very important.
Ubuntu 10.04
Fedora 13
OpenSuse 11.3

I've installed Ubuntu 10.04LTS next to the Suse Partition. But when I start the Computer, Suse 9.1 is not shown.
I've already tried to do sudo update-grub(2) + grub-mkconf + Manually editing the 40_custom file
What information do you need and how can I fix this mess?
PS: I can acces the Suse Partition from Ubuntu (/dev/sda3)

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l

I want to multiboot several Distros for experimental purposes. My main distro is Ubuntu 10.04.Hard drive is partitioned like such: /dev/sda1, grup bios, size = 977 Kib/dev/sda2, file system ext4, size 1.8 Tib, this is mounted on / /dev/sda3 linux swap, 4.3Gib.My question is can I use Gparted to partition a second space out of sda2, and install another Distro? Do I mount it on / ? and will grub boot see both OS without destroying the kernel of my old distro? I am assuming to partition my hard drive I have to unmount it, but can I do this without using a live cd? So many questions and so little help, because apparently this is an easy thing to do.I am just worried just seems that what I just described is too easy and I will probably destroy everything and have to start over.

Have you ever heard of multibooting many distros from the same partition?
Do you need to find a way to install the new Ubuntu 10.04x LTS into an existing partition as another option to multiboot?
Simple, you don't need to download or install any scripts or executables. read on @

I am trying to install Ubuntu10.04 on my machine which already has on it, Win XP. Lemme lay down the setup of my machine first of all.
I got a new 320GB HDD of which I have taken 20GB as the primary partition and installed Win XP on it. Took another 220GB as an extended partition for my data storage. Around 63GB was remaining which I left it as unallocated. Decided to try Ubuntu, but preferred to boot it from the windows bootloader. Downloaded and burned the Ubuntu-10.04-desktop-amd64.iso(have a AMD x3 425 machine) and tried an install on 30GB of the 63 left.
I did not try any partition scheme. I chose the manual partition option, made a 28GB ext4 partition, made it primary, mounted the /, took another 2GB for the swap and proceeded. Chose advanced option and installed grub on the 28GB(/dev/sda6) and completed the installation.
Since no grub was installed, Ubuntu was not available. So then, used the bootpart utility to point grub to the windows bootloader, but it did not work, was giving me error when I chose Ubuntu from the bootmenu modified by the bootpart.
So tried booting with the same install cd, chose Live Ubuntu this time and mounted the 28GB, copied the first 512bytes using dd if=/dev/sda6 of=ubuntu bs=512 count=1 to a usb drive. Rebooted into windows and copied the file to C: and added it to the boot.ini. Rebooted and tried choosing Ubuntu from the boot menu but it does not work. I get a blank screen with the cursor blinking.
The machine is new and BIOS is LBA enabled by auto.

I decided to install my 4th OS, centos. I had some problem and I want to share my experience in this case. After several install and a few kernel panic message, I could successfully dual booted with Ubuntu 10.04 and centos5.5.
First: Boot from DVD and I got kernel panic. A bios update solved my problem (MSI).
Second: When I installed centos without grub and after the install when I wanted to boot in I got something like this: Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)
After 4 days I found out this:
1. I installed every OS, Ubuntu was the last one.
2. I left an unpartitioned free place for centos
3. I installed centos at last. During centos installation, at partitioning, choose "create custom layout"
4. Choose the free place as / and on the next screen you can choose, do NOT install grub.
5. Reboot > in grub choose Ubuntu 10.04 (in my case centos5 already was listed there, but don't go there), because we need to edit the grub.cfg file in ubuntu
My original grub.cfg file, (centos part) was like this:
menuentry "CentOS release 5.5 (Final) (on /dev/sdb3)" {
insmod ext2
set root='(hd1,3)'
search --no-floppy --fs-uuid --set bc47e87e-88c6-4756-8f47-361298b23a16
linux /boot/vmlinuz-2.6.18-194.el5 root=/dev/sdb3 }
I changed it for this:
menuentry "CentOS release 5.5 (Final) (on /dev/sdb3)" {
insmod ext2
set root='(hd1,3)'
search --no-floppy --fs-uuid --set bc47e87e-88c6-4756-8f47-361298b23a16
linux /boot/vmlinuz-2.6.18-194.el5 root=UUID=bc47e87e-88c6-4756-8f47-361298b23a16
initrd /boot/initrd-2.6.18-194.el5.img }
Save, restart and this time I could boot in to centos. After Ubuntu kernel update, you need to edit grub.cfg again!

've been looking for the answer both on the web and this forum but I couldn't find it;How can I put Ubuntu, Encrypted Ubuntu (Luks + LVM), Backtrack and eventually WinXP on the same drive with a Grub2 as a bootloader?I'm a bit confused about partitioning; I suppose that I need only one /boot partition to store the kernel of the encrypted Ubuntu, while the other distros will have their /boot within each partition, like this:
1) 500 Mb; /boot for the encrypted Ubuntu on partition #2
2) 10Gb; Luks + LVM Ubuntu
3) 10Gb; clear Ubuntu (whose /boot is in same partition #3)
4) 2Gb; Backtrack
5) [Win..]
In this case, will the update-grub command find and recognize correctlyll the OSs or should I edit something in the "40_custom" file

I have a USB PenDrive (FAT32 file system) that has 2 boot options. Boot option 1 = runs a program that updates my BIOS. Boot option 2 = runs a program that executes a basic hardware test on the PC. I don't need to access any HDD or load any operative system. the pen drive is using a DOS bootstrap (like the one you obtain when you format a device using /s option under DOS).
Can I use an advanced graphical bootloader to accomplish the same thing? It would be nice to have a background bootsplash logo of the company, while the user selects one of the two boot options, using the cursor keys. Just like GRUB...

I just got a new netbook and want to install several distro's to play with so would appreciate any advice you have. I have a 160gb drive so was going to dedicate 10gb to each distro and to xpsp3 that is comes with and about 2-4 gb for meego. Here are the distro's i want to install if possible...I am in love with KDE again so starting with Kubuntu
the last 100gb I was wanting for mp3/movies/docs.i was planing on putting the 100gb in NTFS so it could be shared with each OS? Not sure if that is possible or if there is a better solution but i want to be able to access the files from each os - in linux you just mount that partition to access it? and then i would also be able to access it via windows. I am assuming windows cannot see the ext3 file system and/or it is easier to use NTFS?right now xpsp3 is installed so not sure if can back it up via usb or if i can just download a version and burn a cd as i have a key and use WinToFlash to put it on a flash drive or can i just make partitions leaving the xpsp3 install on the netboot?
Any opinions on filesystem / order of installs / how much drive space is ideal per distro / is it even possible for that many os's / which boot loader to use?

I installed Fedora 12 on my second drive.
Xubuntu 9.10 is on my master drive, and I use it to install/update grub.
When I installed Fedora, I answered "NO" to installing a boot loader.
After install, I booted Xubuntu and ran update-grub, grub couldn't find (apparently) my new fedora install.
I've tried adding it to /etc/grub.d/40_custom, and when I list /boot/grub/grub.conf, it appears to have added Fedora to the bottom of the menu.
When I boot, it doesn't stop at the grub screen, indicating only one installation of linux.
Here are the pertinent file listings, can you see where I've gone wrong?
Code:
dav@dav-desktop:~$ cat /boot/grub/grub.cfg
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates

I have used Ubuntu 8.x before side by side with win XP with absolutely no problems, today I have a windows 7 working great, but it was not enough for me so I've installed winXP on another NTFS partition, and then installed the Ubuntu 8, but the problem is that grub didn't detect windows 7 only detected Ubuntu and win xp ( and win XP under the name "windows Vista" !!). I did rename the win XP thing, not big thing, but there still the main problem of windows seven, it's not detected yet. So what I have done is downloading Ubuntu 10.10 beta and repeated the same thing after deleting the previous partition that Ubuntu 8 was on and created new one and used it. But the problem stays the same.
I have 80 GB - all one partition - windows 7
and 1 TB - 359 GB -storage
-26 GB - windows XP
-26 GB - Ubuntu 10.10
- ~4 or 5 GB - swap
-443 GB - storage
I know it's not organized enough but I couldn't do better using win7 storage management tool So what should I do to make windows 7 detected by grab and bootable, and I really don't want to format any drive,specially win7.

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

I was installing Fedora 13 on my computer as I need it for a class I'm taking but wanted to keep Ubuntu (10.04) as well. So now the setup is: Windows 7 on sda, Ubuntu and Fedora on sdb.I did not install the bootloader when Fedora 13 prompted to. Running sudo os-prober and sudo update-grub only finds Windows 7.I know I can manually add it in 40_custom but have no idea how to go ab out that. The output of my fdisk -l is as follows:
Code:
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders

I have a LiveCD of the Lubuntu Lucid 10.04 Beta. First, I will say, I'm extremely impressed with Lubuntu. It's incredibly lightweight, pretty intuitive to use, and very pretty when compared to other distros of comparable weight (eg, MEPISLite, wattOS etc.) The only problem is that when I click "Install Lubuntu," NOTHING HAPPENS. Is it just because it's the Beta?

I'd like to install xp, win7, fedora, ubuntu. I installed xp then I used gparted to create a partition before xp and installed w7 both can dual boot fine. I installed fedora 12 in grub I can see fedora and windows bootloader. I can get to win7 and login fine. When I go into grub, then win bootloader, then xp, I can get to the login screen, but I can't login. I enter my pw, it takes several seconds, seems to login, then quickly logs out. I see "closing network connections", then I'm back to the xp login screen again. I'm not sure why I can't login to the xp partition. Fedora and win7 work fine. Win7 & xp worked fine before fedora. Grub menu.lst looks ok. After fixing this, I'd like to next install ubuntu
hd0,0 - sda1 - w7
hd0,1 - sda2 - xp
hd0,2 - sda3 - extended
hd0,4 - sda5 - fat32 (data)
hd0,5 - sda6 - /boot fedora
hd0,6 - sda7 - / fedora
hd0,7 - sda8 - swap fedora

I have a laptop with 250 GB SATA HD that has the following:
Win7 Pro installed first with sda1=system reserved partition, sda2=C: drive, sda5=separate software application programs to differentiate from Windows' Program Files. Ubuntu 9.10 was installed next (sda6=common swap partition for all Linux distros, sda7=Ubuntu root, sda8=Ubuntu home). Then Opensuse 11.2 was installed with sda12=root and sda13=home. Finally FedoraCore11 was installed with sda9=boot, sda10=root and sda11=home. Ubuntu and Suse have grub loader in their own root partitions.
Suse's grub menu controls all OS's. From this grub menu I can select Windows or any other Linuxes. Suse uses legacy grub because it was installed right after Ubuntu 9.10 which uses (legacy) grub.
Here is opensuse's grub menu:
# Modified by YaST2. Last modification on Wed Mar 31 11:49:28 EST 2010
# THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader
# Configure custom boot parameters for updated kernels in /etc/sysconfig/bootloader
default 1
[Code]....
Somehow I also messed up Windows' boot file and boot partition table. Now I am still trying to use Windows installation CD to repair Windows but it has taken several hours and am still waiting for screen response. I cannot boot into any Linux distro either.

I'm having an issue with GRUB, I have four OSes on my hard drive. Here they are in the order I installed them:
Windows 7 (Windows bootloader)
Ubuntu (GRUB 1.97)
YLMF OS (GRUB 2)
Debian (Some ancient bootloader)
(For those of you unfamiliar with it, YLMF OS is an Ubuntu-based distro re-skinned to look like Windows XP. Other than the theme and branding it's exactly the same as Ubuntu) Each time I installed another operating system, it replaced my original bootloader with its own. I made the mistake of installing Debian last, thus leaving me "stranded" with an old version of GRUB. Since at the time I was relatively inexperienced with Linux, I solved the problem by reinstalling Ubuntu, which then replaced the bootloader with GRUB 1.97.
I mainly use YLMF OS, and so when I wanted to change some GRUB menu settings (the default entry, timeout, etc.) I naturally changed the /etc/default/grub file in the YLMF OS partition, not the one in Ubuntu. Once I rebooted I realized that my changes weren't being applied for that reason. Thus my problem is that my computer is using the GRUB that Ubuntu installed, not the one YLMF OS came with. How do I change which version of GRUB is used when I boot up? Yes, I could just change the settings in the Ubuntu partition, but YLMF OS came with the newer/est version of GRUB, so I want to use that instead.

I have a triple boot system with Windows XP, Debian Lenny, and Fedora in that order as far as the disk partitions, and Lenny's grub controlling the multiboot. This has worked well for yearsRecently the Debian got corrupted with someependency issues, and I want to install Squeeze inplace of the existing LennyI don't need to save anything from the Lenny). Is this possible, usinga startup install CD for on-line installation of Squeeze over the Lenny partitions, and also without disturbing the Windows and Fedora boots? If it is, are there any manual steps to be taken during
the installation?

Just migrating to linux but I don't want to give up linux just yet so I've stuck in a 2nd hard drive to install linux on which I've done, now I have windows on one hard drive and linux on the other but my computer boots straight onto linux. I need the option to choose which os to boot into on startup which I've heard GRUB is the best option but I have no idea how to go about setting this up.

I recently installed Lubuntu to a USB. It was up and running and worked fine, however, upon exiting and going to boot into windows, I noticed it had installed a GRUB bootloader. I use whole disk encryption on windows, which has its own bootloader, so I can't be having some other bootloader on the PC interfering with this. I used my rescue disk to restore my WDE bootloader, but the USB stick will not boot now.
I also tried using pendrivelinux but this copies the live cd version onto the USB stick and nothing saves when you log off.installing Lubuntu to USB without a boot loader?

I want Truecrypt to ask for password for Windows XP as usual but with the standard [ESC] option, on selecting that, i.e via Escape key, I want it to find the grub for the (unencrypted) Ubuntu install. I've installed Windows XP on the 120Gb hard drive of a Toshiba NB100 netbook then partitioned to make room for Ubuntu 10.04 and installed that after the Windows XP install. When I encrypt Windows XP, Truecrypt will overwrite the grub entry in the master boot record (MBR), I believe (?) and I won't be able to choose between XP and Ubuntu anymore. So I need to restore it back.
My setup:
Partitions:
Windows XP, NTFS (to be encrypted with Truecrypt), 40Gb
/boot (Ext4, 1Gb)
Ubuntu swap, 4Gb
[code]....
The key area of the problem is how to instruct Truecrypt when escape key is pressed, and how the Grub/Ubuntu can be made visible to the truecrypt bootloader to find it, when the esc key is pressed. Also knowing as chaining.

I've just created a bootdisk (ssd) with multiples Squasfs images I can choose to boot at the Grub2 menu.No I tried to put the sqfs-images into a ramdisk. Therefore I edited the script '/usr/share/initramfstools/ scripts/ casper'. I used the 'dirty hacks'in the ubuntuforums.org/boottoram howto but I suited them for my needs.Now the Systems stops after the kernel and doesn't find a root system.
The sqfs-image without the modification of the 'casper'-script still boots but doesn't load into ram completely.

I have a GRUB2 USB multiboot setup. Plus I have a multiboot setup on my computer with Ubuntu 9.10, PCLinuxOS, Windows XP, and Fedora 13. The issue I'm having is different but the same. On my USB multiboot, Fedora will hang up on certain devices. Things such as touchpad, bluetooth, etc. On my PC it hangs up on first the bluetooth, then I unplug, then the USB hub, then the mouse and finally the external hard drive. It detects the devices but it freezes on detection. I did get this error before the device detection began:
Quote:
dracut; dracut-005-3.fc13
dracut: FATAL: Don't know how to handle 'root=(0,4)'
dracut: Refusing to continue
dracut: FATAL: Don't know how to handle 'root=(0,4)'
dracut: Refusing to continue
this is on the PC and the problem with the USB is that it will hang up when detecting devices.
