Ubuntu Installation :: Another Dual Boot Grub2 On 10.04?
Jun 8, 2010
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
[code]....
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 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 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

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'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'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 went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?

Today I attempted to install Win 7 on my Ubuntu 11.04 machine so I could dual boot. The Win 7b install went smoothly, but when I tried to fix grub everything went to hell.
I initially tried to reinstall grub using this walk though [URL] However, when I start the computer I get:
"GNU GRUB version 1.99~rc1-13ubuntu3
Minimal BASH-like line editing is supported....
grub> "
I tried to use the technique in [URL] to solve the problems, but when I try to run chroot I get a bin/bash error (I don't have the full error handy, but can rerun the steps if needed). The only potential cause that I can find doesn't apply to me since I am using a 11.04 64 bit live usb on a 11.04 64 bit install.
I've run [URL] and included the results below.

I have read that installing ubuntu 10.10 will inevitably install grub2 with it(unless you use flash drive workaround). i am wondering how slackware 13.1 reacts to grub2.
Does it go on like nothings changed (if configured correctly)? Or does it freak out and have a fit? If slackware doesn't play nice with grub2. i don't think i will use ubuntu 10.10.

I have a win7/10.10 dual-boot set up, more or less following the lifehacker.com tutorial (I know, I know). I had to reinstall windows, and its taken over the MBR so that only win7 boots now. My shared drive and the ubuntu filesystem are still there, I just can't get to them without a boot cd. So, I tried to follow the tutorials, which all basically say to reinstall grub or grub2. I tried one method, but ubuntu told me that installing grub2 anywhere but the MBR was a bad idea

i had a dual boot with xp and lucid lynx, then upgraded the xp to win7. windows commonly overwrites grub with it's bootloader. and so it did. now i can't access my lucid OS. i need to get grub back (i need to get lucid back).

ubuntu@ubuntu:~$ sudo fdisk -l

Dual boot PC, boot disk and WIN XP are on good disk, Ubuntu was installed on failed disk. (I prefer separate disks for each OS).
I know I will need to reinstall Ubuntu later, and of course, GRUB2 now crashes without the Ubuntu disk.
Confirm that the only thing I need to do when I get the new drive installed and partitioned is to boot my XP disk in Recovery Mode and type "fixmbr", (then reboot to confirm clean WIN operation on the existing disk) then install Ubuntu as normal on the new disk.

I'm using opensuse 11.2 and a week or so ago it suddenly stopped shutting down the computer, or rebooting. It shuts the screen down and that seems to be it, so I have ti switch it off. However a day or so later it began to reboot when asked, but still won't shut down. I'm dual booting it with Unbuntu 9.04 using grub2, but it's been that way for many months without problems.

The Problem, installing ubuntu over top of windows and vice versa causes the windows boot menu to forget about ubuntu.The Solution:1. Using bcdedit from within windows to edit the boot menuClick Start -> Type Cmd.exe run it in elevated mode (as an administrator) by right clicking it and selecting "Run As Administrator" Inside the console type bcdedit, notice that the ubuntu boot entry is still there, for example i use three o/s , windows 7 professional x64, windows 7 ultimate x64 and Kubuntu and it looks like this

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.

9.10 uses GRUB2, so the instructions below are obsolete. Is there anyone here who could provide instructions for adding Geexbox into the GRUB2 menu? If you already have a Linux OS installed on your system, you might just want to add a GeeXboX entry to your existing bootloader. This allow you to install GeeXboX very easily. From GeeXboX CD, simply copy the GEEXBOX folder into your Linux / partition (we suppose it to be /dev/sda1 here).
Modify the /boot/grub/menu.lst file to add:
title GeeXboX
root (hd0,1)
kernel /GEEXBOX/boot/vmlinuz root=/dev/ram0 rw rdinit=linuxrc boot=UUID=$my_uuid lang=en keymap=qwerty splash ...
initrd /GEEXBOX/boot/initrd.gz
quiet
Just take are about two things:
- the field root (hd0,1) is to be adapted according to the rest of your GRUB's configuration.
- the $my_uuid value is the unique ID of your partition. Check within your GRUB config file, which value is set for other OS on the same partition or use ls -l /dev/disk/by-uuid/ to see which uuid matches your partition.

I am quite experienced user of Ubuntu desktop / server distributions. Recently my desktop 9.10 disk failed and I decided to reinstall using 10.04. My configuration is a dual disk dual bot system. I have XP Pro SP3 on one disk and Ubuntu 10.04 on second. XP has own, untached MBR ubuntu got Grub 2 installed on the same disk as Ubuntu. Ubuntu disk is booting first in BIOS. Grub 2 detected both system, however I can boot only to Ubuntu. When I am trying to boot XP I got black screen only. Looks like booting is stack in BIOS stage, because crt+alt+del reset system.
I read Ubuntu forum, search Google and did not come with any solutions. My XP MBR is OK. I can boot directly, choosing XP HDD in BIOS as a starting disk. All entries in grub.cfg looks fine to me. I made 3 different clear installations of Ubuntu. Each with the same result. I reinstaled Grub2 with no effect. I wonder if this may be a hardware/Grub 2 compatibility issue. I am using quite old components.My motherboard is Assus P4C800 Delux. I have 5 HDDs 2 CD. Exactly the same configuration was OK with 9.10/XP dual disk dual boot using Grub legacy.

GRUB2 won't boot. It hangs just after the 'Boot from CD' thing in my BIOS.I've had 1.97 working on my PC about 24 hours ago, but I decided to start afresh and go for Xubuntu 10.10.I'll post the PC specs in the morning, but in the meantime, does anyone know how to fix this?It's going to be a Xubuntu only system, and I've tried to repair the GRUB files via the Live CD and here.

So I have a really old (about 10 years) desktop PC manufactured by Packard Bell, and would like to get Lubuntu 10.10 running on it. I had previously burnt a CD with it, but boot time was incredibly slow on the machine and installation of Lubuntu crashed my system. As a result, I created a LiveUSB (as you do).
When I entered my CMOS, I discovered the BIOS on my machine isn't able to boot from USB, and I wasn't able to find a BIOS update for my AMIBIOS chip on the American Megatrends website. So I booted my GParted Live CD and created an ext4 partition at /dev/sda3, which I proceeded to install GRUB2 onto via the commands:
Code:
$ sudo su
# mkdir /mnt/grub/
# mount /dev/sda3 /mnt/grub/
# grub-isntall --no-floppy --root-directory=/mnt/grub /dev/sda
This, as planned, succeeded; I can now get into a GRUB2 prompt when my machine boots...! The only problem is, GRUB2 won't detect my USB...or any device other than my hard drive
So, is there any way I can get GRUB2 to find my USB?
P.S. The USB works fine on my laptop, which does support USB booting. I can also boot the USB on my laptop via its GRUB2 command line, using:
Code:
grub> set root='(hd1,1)'
grub> chainloader +1
grub> boot

I have a asus eeepc 1101ha. With Karmic,it would boot into w7 without problems.I installed Lucid on another partition,and after that the w7 grub entry would leave me with a blinking cursor in the left top corner, and hang.
I booted with the w7 dvd, ran bootrec.exe to restore mbr and bootmgr, and the booted into w7 to confirm. It was working. Then I booted with the live dvd, mounted the lucid partition, and installed grub. Now choosing the w7 entry would ask for the boot media, and pressing any key would bring me back to the grub menu. Lucid and karmic boot without problems.
Installing grub from karmic now gave the same error. Running update-grub didn't change anything.As I had to use w7, I booted again from the dvd, and restored again mbr and bootmgr. Booted into w7, used it, then once again to the live cd, to reinstall grub, and once again the w7 entry in grub makes grub ask for the boot media.I've attached my boot info script.Ah, I also played with the bootable flag for the /dev/sda1 partition, but it didn't change anything.

I used to have 2 HDDs for ubuntu: 1 x 80GB and 1 x 500GB The 500GB disk was my /home directory and is now used exclusively for Windows 7. I have now moved /home to the 80GB drive and have modified /etc/fstab to point /home to /home rather than /dev/sdb1. However, I cannot boot into ubuntu. I have tried using Super Boot Disk cd-rom but still no joy. I think I need to fix grub and have tried by booting into a Live-CD and following a tutorial I found on the forums but it complains about not being able to find a device.map I guess this has something to do with the fact that the 500GB HDD is now gonoe but am not sure how to resolve this issue. how to recreate this file but the command failed.

menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set 3850d16450d12980
chainloader +1
}
This is automaticly genarated after installed ubuntu 10.10. It shows black screen with a flashing cursor after press enter. Grub 0.97 also does this with:
title win7
fallback 2
find --set-root --ignore-floppies /bootmgr
chainloader /bootmgr
savedefault --wait=2
But the wierd thing is my usb stick can boot windows 7 succesfully with the same configuration. Whats wrong with that? How can do with grub.cfg?
