Ubuntu Installation :: GRUB2: Setup For Dual-boot With Arch
Nov 26, 2010
I'm thinking of dual-booting Ubuntu 10.10 and Arch Linux. It seems that I'll have to do some editing of the grub.cfg file, but I have seen numerous warnings not to do so. After a bit of poking around, I've heard about a script that does the editing for you built in to Linux (or maybe just Ubuntu).
My questions are:
- If the aforementioned script does exist, how do I use it?
- else if it doesn't exist, how do I not directly edit grub.cfg?

I recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?

After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-
[Code]....
Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-
[Code]....
But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off

I've already had WinXP SP3 installed on one HDD, so i've installed 10.04 on my spare HDD. When I try to boot to Win, I get ntoskrnl.exe missing error. This is my boot info script report:
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Windows is installed in the MBR of /dev/sda
=> Windows is installed in the MBR of /dev/sdb

I've tried with different boot orders in bios, reinstalling Grub2 (several times ), I've even tried to install lilo through software center but didn't know how to configure it ...

I recently installed Ubuntu 10.04 on my dual boot system and noticed that my boot options were changed. I typically have Windows XP as the default OS. Here are the steps that worked for me to get Windows XP as the default boot using Grub2.During my initial Window XP install I had partitioned my hard drive into 3 partitions:
Code:
Partition 1: NTFS format (Windows XP installation) in Linux it is called /dev/sda1
Partition 2: NTFS format (Data for Windows XP) in Linux is is called /dev/sda5
[code]....

Been using Linux for many many years but Grub2 is annoying the heck out of me at the moment.
My home desktop PC is set up as follows:
/dev/sda � 40GB 10k Raptor with Ubuntu 10.10 installed
/dev/sdb � 500GB HDD formatted to ext4
/dev/sdc � 500GB HDD split up as follows:
/dev/sdc1 � 80gb NTFS partition with Win7 installed
/dev/sdc1 � Remaining drive space NTFS but nothing on it yet
Grub2 refuses to detect that Windows is installed on the 3rd HDD. I've googled and spent hours trying all sorts of things to get it to detect it and add it to my boot menu.
If I disconnect all drives except the Windows drive it boots up straight into Win7, so it's healthy and happy. (as healthy and happy as Windows can be, I need it for work purposes only!)
Does anyone have any tips on what would be the best method to force grub to realise that Windows is sitting there?
As far as I understand, the Win7 partition should be (hd2,1) � does that sound right to you?
I haven't tried booting off an Ubuntu CD and re-installing grub, since I can get into Linux and all the guides seem to be about how to restore grub after a Windows install eats it...

I've just installed the 64 bit edition of 9.10 on my workstation. My raid drivers worked without any custom installation, which is very impressive! I am however having a problem installing grub2. I boot to the live CD, run the install process, resize and partition my free space as an ext4 primary partition with mount point /. Everything installs except grub, so I'm always booting in to windows.This seems to be a bit off as I've never had this occur with dual booting before.

I have a Dell Studio 14 laptop with Windows 7 64bit preinstalled. The processor is core i5 and the machine has 4GB RAM. I freed 25GB of memory from my Hard disk and tried to install Ubuntu 10.04 (AMD). Everything went fine. I restarted and Logged into Ubuntu. It worked like a charm. Then I restarted to Windows7. This also worked well as expected.
But, when I rebooted again, I got a black screen saying that �No modules found. Press any key to restart�
When I press a key, it says �No operating system found�, probably after checking through a network (it printed lines starting with PXE).
I tried exactly in the same way with Ubuntu 8.04 in my machine, and this worked without any problem. The Bootloader was not corrupted after restarting from Windows. I noticed the problem with Ubuntu 9.10 and 10.04. I feel like a problem regarding the bootloader version. AFAIK, 9.10 and 10.04 is using GRUB2 when 8.04 use the old version of GRUB. Will I have to switch to the legacy GRUB? (I would love to keep using GRUB2). If yes, I would like to know How.

I have a Dell ZINO HD and dual booted fine prior to 10.04. Grubs seems to not identify the Win7 OS partition correctly. According to Disk utility DEV/SDA1 is a DELL utility partition, DEV/SDA2 is the RECOVERY partition, DEV/SDA3 is my Win7 OS partition...and DEV/SDA5 is my Linux partition. Ubuntu boots fine... but with GRUB using SDA2 (HD0,2) for win7 I cannot boot to it... is there a fix?
The following is in my GRUB.CFG file
### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Windows 7 (loader) (on /dev/sda2)" {

Problems with dual boot, grub2 auto os prober
Drive #1 (sda) Master CS Ubuntu 9.04 grub upgraded to grub2 version 1.96
Drive #2 (sdb) Slave CS Ubuntu 9.10 grub2 version 1.97 /boot is (sdb1) root is (sdb5)
grub2 is installed in /boot (sdb1) and the mbr of (sdb)
I want to be able to boot drive #2 from drive #1 grub menu at boot time. I have run �update-grub and it probes and finds (sdb5) and creates a new grub.cfg called grub.cfg.new in the /boot folder, but the new cfg file does not show (sdb5) or (sdb) it shows all other changes that I made such as splash screens and they are working. How do I get it to recognize drive #2 with Ubuntu 9.10. I can boot each drive independently of one another and I can boot 9.04 with 9.10 if I swap the drives around. And run update-grub The auto probe is working in the Ubuntu 9.10 and may be working partly in the 9.04.
This may or may not be a problem, but is a pain anyway. When I run update-grub in 9.04's grub version 1.96, it does not change anything in the current grub.cfg it does make a new file called grub.cfg.new I have to go into /boot/grub and change grub.cfg to old and change grub.cfg.new to grub.cfg I do not have this problem running the same command in Ubuntu 9.10's grub. It finds changes and os's and automatically updates the current grub.cfg

I have two hard disks sda and sdb. I have Windows XP installed on sda2 and Ubuntu 10.04 on sdb5. When I installed Windows XP, Ubuntu stopped booting. I tried to repair grub2 from a Live CD unsuccessfully. Now I have completely messed up my MBR of both HDDs. I just want to configure grub2 to load both OSes in dual boot mode.

I have a windows 7 machine and installed ubuntu 10.4 32 bit in its own partition. I want to replace the 32 bit ubuntu installation with a 64 bit installation. I downloaded the 64 bit version, booted up on the install cd, and started the install. I got as far as the partition set up before chickening out. I was going to use the manual partition option, select the existing ubuntu partition, reformat, and install. I chickened out because i was afraid that this would also reinstall the grub boot loader without the dual boot option disabling my ability to get into win 7. How should i proceed so that i can replace the existing 32 bit ubuntu with a fresh 64 bit install and still be able to boot into win 7?

I currently have xp installed on the 1st partition and Ubuntu installed on the 2nd.Both partitions are on the same drive.(Being the 1st drive)I have just purchased a new case and some other components and wish to take the opportunity to change my current setup so that xp is on the 1st drive (alone) and Ubuntu on the 2nd drive (alone) Using clonezilla, I take a backup of each partition separately.I then copy back the xp partition to the 1st disk. I then copy back the Ubuntu partition to the 2nd disk.I gather at his point i run the live Ubuntu cd, open a terminal and run sudo update-grub.

I am planning to move my main OS from Windows to Ubuntu (Yeah I am that impressed) but I wish to move windows to my current smaller hard drive until I find all ubuntu replacement programs i can use then eventually eject the windows drive. The problem is has we all know who dual-boot you have to install windows first before ubuntu as the windows mbr is when grub is stored and gets wiped when you install windows.
It must be possible to add windows as secondary OS while keeping / or reinstating grub must it not it surely (eg on 10.4LTS release it would be ok, but if i installed windows vista or 7 on my secondary hardisk it would destroy grub).

I have Win XP installed on one hard disk drive (HDD1) and Ubuntu 9.10 installed on another hard disk drive (HDD2). Win XP was installed first then Unbuntu 9.10 which set up a dual boot menu. Win XP will no longer boot because I changed the BIOS setting from IDE to AHCI. The problem this causes is described at [URL]. The problem is that if you installed Windows in IDE mode (ie you didn't use F6 and supply a driver disk), then simply changing the BIOS setting to AHCI mode and rebooting will cause Windows to fail and will require a repair install. Most people have been advising to reinstall Windows if you want AHCI enabled. I have read that Win 7 supports AHCI "out of the box" so instead of re-installing Win XP I want to install Win 7 to replace it. I would like to know in advance what installing Win 7 will do to the dual boot menu?

I have the following PC set up:
Dell 8400 with 3 GB of RAM with 3 160 GB SATA drives:
The first one has Windows XP installed on it.
The second one has been newly formatted and Ubuntu 10.04 has just been installed on it (20 GB / and 6 GB swap) with grub being installed on the first partition and not the master boot record. The remainder will be for storage for Windows.
The third drive is simply storage for Windows.
At this point I am able to boot XP just fine, but I'm not able to boot Linux. I just getting a blinking cursor or the PC just reboots when I choose Linux. I believe I have set up my boot.ini properly using:
C:Bootsectc.lnx="Linux Ubuntu"
After running dd if=/dev/sdc1 of=bootsect.lnx bs=512 count=1 and putting that file in place.
For reference, I don't believe this is a Linux problem, as much as I am simply trying to guide the ntldr to be properly pointed to a place where it can boot Linux. When I go into the bios and disable the first and the third hard drives, grub pops right up and I'm able to boot Linux with no problem, so that piece is fine. I think it's just now trying to get the correct syntax so I can boot Linux without having to disable drives and reenable them.
For kicks I even tried these syntax types in boot.ini:
multi(0)disk(0)rdisk(1)partition(1)="Linux11"
(i.e. 2nd disk, 1st partition ...etc...)
I read many troubleshooting documents on dual booting and so forth but I just can't get this right. For reference, I stated the way XP views my Hard Drives in the intro, which seem to be a different order than Linux sees them, yet I believe I've tried all the combos of settings for this to work (yet clearly have not). I have attached the output of boot_info_script*.sh here: [URL]. Boot Info Script 0.55 dated February 15th, 2010 ..... Devices which don't seem to have a corresponding hard drive.

I'm trying to setup a dual boot of windows 7 x64 and Ubuntu 10.10 i386. Before I got windows 7 and the new graphics card it ran 9.10 perfectly. If I take the card out (Nvidia 8800 Ultra), it will install fine but when I put the card back in, it crashes. It appears that it just doesn't like the card.

I need a suggestion on setting up a dual boot menu for my setup. I have two hard drives one with WinXP and a second one with CentOS 5.3 installed. I basically moved the hard drive from another identical machine to this one and so I want to setup a boot menu to access either windows or Linux. CentOS already has grub on it.
What is the simplest method of setting up the dual boot menu? I would like something which is easy to administer which I can just ghost over either the Linux drive or Windows drive or disconnect either and have either boot just fine. I don't ask for much do I?
If I have to go through a little process after ghosting over one or the other drives that would probably be ok. We get updated images for this machine and replace the image on the drives with new images, although Linux shouldn't be reimaged, just windows. So the Linux drive (2nd drive) should not be touched normally.

The problem is, on a machine, you can only have 4 primary partitions. sda1 and sda2 are my Vista and Recovery partitions respectively, which eliminates two of my primary partitions already. I myself have never used logical partitions, and was wondering if any of the partitions the Beginner's Guide recommends (/, swap, /var, and /home) could be made logical, and if I even need a swap partition.

(This is for a 100% Clean install)
Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?
Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?
Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?
I have a total of 3 HDDs on this system:
-- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup
-- 1x 320GB WDD HDD (non RAID setup)
(The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)
I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).
I have the latest version of the LiveCD created already.
Q4) Do I need the Alternate CD for this setup?
I plan on installing XP before Ubuntu.
This is my 1st time dual booting XP with Ubuntu.
I'm using these as my resources:
- [url]
- [url]
Q5) Anything else I should be aware of (possible issues during install)?
Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?
(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.

I have a computer with windows xp on it, and i want to dual boot with fedora 11. I have 2 hard drives in it, 1 500gb HD and 1 350gb HD. the 350 isnt much concern b/c its just sitting there all free and unpartitioned right now. Now my 500gb is split into 3 partitions, a 20gb(with xp installed on it) a 105 gb with pretty much nothing on it and a 350gb with all my data.
My problem is I'm trying to resize my 20gb partition through the fedora 11 installer and when I tell it to resize say to 10gb it starts and fails the resize. its a NTFS partition and the windows stuff on the partition is only about 8gb. any idea whats going on? the only error I get is "The resize has failed"
