Ubuntu Installation :: How To Change Default OS In New Grub Version

Apr 26, 2010

I have just installed Ubuntu 9.10 on a laptop previously running 8.10

I am unable to change the default OS in Grub from Ubuntu 9.10 as I cannot find /boot/grub/menu.lst.

How do you change the default OS in this newer version of Grub.

Ubuntu Installation :: Can't Change Default OS In Grub

Feb 7, 2010

I recently installed Karmic, and want to change the default Grub entry to Windows XP. Having done some research and tried things out, I am a bit confused. I have edited etc/default/grub so that it has GRUB_DEFAULT=6 (to correspond to my XP installation) and GRUB_TIMEOUT="3", but after running sudo grub-mkconfig the grub.cfg file still says set default="0".

Ubuntu Installation :: Multiboot - Change Which Version Of GRUB Is Used When Boot Up?

Aug 18, 2010

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.

Ubuntu :: Changing Up Grub - Not Pop-up And Just Boot The Default Version ?

Jul 2, 2011

I am currently doing a tri-boot (using refit) with Linux, Windows, and OS X. I was wondering if it was possible to change up the boot loader for Linux. I basically wanted grub to not pop-up and just boot the default version of Ubuntu. Also the boot loader comes up with the options to boot Windows and OS X and I was wondering if it would be possible to remove those from the list as well?

Debian :: Can Change My Grub Version

Nov 13, 2010

I want to use Remastersys Backup, but their webpage [url] says that it only works with Grub-legacy, not with Grub-2 (Grub-pc).

What I currently have is Grub-2, and the question is can I safely switch from that to legacy, i.e., with a simple synaptic remove and install?

The Remastersys package actually wants to install, also in synaptic, the dummy package "grub"; so should I allow it to take care of the switch, or do I do it myself as above?

Using Debian Squeeze only, no multi-booting.

Ubuntu :: Change Default Kernel In Grub?

Jul 21, 2010

I have Lucid on my laptop. Unfortunately, with the various 2.6.32 kernels neither hibernate nor suspend work, so I've installed and use the last 2.6.31 kernel that came with Karmic.Now, I'd like to set it as default, so that I don't need to actively choose it when I boot. The problem is that I can't find a way to set Grub (version 2.0, or 1.96rc, can't remember) to pick the 2.6.31 kernel and if I try to uninstall the 2.6.32-23 kernel synaptic says that linux-generic and linux-headers will also be uninstalled (not just the parts specific to 2.6.32-23).

Red Hat / Fedora :: GRUB - Change Default OS To XP Always?

May 25, 2011

I'm somewhat of a n00b. I have a dual boot machine running XP and Fedora Core 14. I like my default boot always to be XP. Right now, XP is default BUT every time there is an update to Fedora, it will change the default to Fedora. I now have to edit grub.conf to boot from xp again. Is there a way to make xp always as the default even after an update?

Ubuntu Installation :: Adjust The Default Setting Via /etc/default/grub?

May 29, 2010

I have already had Vista installed on another drive and from what i've read on the webs you get to dualboot if you install ubuntu after vista. when i did install it (i installed on a blank hdd with no partitions, choosing the "erase entire disk" option since for some reason default option was attempting to eat a part of my windows 1 gb drive instead of using disk i specially made for it) and the grub 2 loaded for the first time, there was NO option to run vista. only 2 linux (normal and recovery) and 2 memtests. I've ran linux and went to google this. I found that i should add something to some config files in /etc/grub.d/From reading the readme file i understood i could add my own files that are named like NUMBER_SOMENAME and insert code into them. Because it said:Quote: For example, you can add an entry to boot another OS as01_otheros, 11_otheros, etc, depending on the position you want it to occupy inthe menu; and then adjust the default setting via /etc/default/grub. But then i found a file 40_custom that said:

Code:
#!/bin/sh
exec tail -n +3 $0

Ubuntu :: Change The GRUB Bootup Menu's Default Choice?

Mar 3, 2010

Yesterday I installed on my laptop (an IBM Thinkpad T42) "virt manager" using the Synaptic Package Manager. I'm running Karmic.

As part of the installation, SPM had me reboot the computer (which is dual-booted with Windows XP, which I use less than 1% of the time). The new GRUB screen came up showing two new initial lines, the first 2 of the following 4 lines:Ubuntu,

Linux 2.6.31-19-generic-pae
Ubuntu, Linux 2.6.31-19-generic-pae (recovery mode)
Ubuntu, Linux 2.6.31-19-generic
Ubuntu, Linux 2.6.31-19-generic (recovery mode)

When I allow the default choice of the first line to prevail, Ubuntu boots up into a condition in which the Wireless Network Connection fails to open, and in which nothing I've been able to think of makes it open.

If, instead, I scroll down to the third line (which was the initial default choice line, i.e., the default choice line prior to the "virt manager" installation), Ubuntu boots up into a condition in which the Wireless Network Connection operates as usual, viz., immediately.

Scrolling down works, but it would be better, it seems to me, to return to the condition in which the current line 3 either becomes line 1 or else becomes the default bootup choice.

I've used SPM to uninstall "virt manager", but the 2 new intial lines in the GRUB options remain. I understand that with Karmic's version of GRUB, viz., GRUB-2, it is no longer possible to change the bootup menu choices easily.

how I can either eliminate the first 2 lines in my current GRUB screen, or make line 3 the default choice?

Ubuntu Installation :: Grub Errors - More Than 1 Grub - The Change Does Not Appear In The Boot Up Menu

Dec 22, 2010

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).

Ubuntu :: 9.10 Won't Boot - How To Change GRUB Default Boot Choice

Jan 5, 2010

I tried to do my parents a favor by installing Ubuntu 9.10 alongside WinXP on their PC -- same configuration I have on my desktop at home. The install went fine, but since I made a poor buying decision on purchasing a MSI motherboard in the past, Ubuntu immediately crashes after boot (other MSI board users having the same issue, no help from MSI).

The computer tries to boot Ubuntu by default unless something else is selected from the boot menu. How do I change the boot preference from default (choice 0) to WinXP? I tried manually changing this (editing the grub.cfg file), but the file said not to edit, that it's generated by something else...How do I have WinXP load by default instead of the broken Ubuntu?

Ubuntu Installation :: 10.04 - GNU Grub Version (Recovery Mode)

Feb 26, 2011

I am trying to install ubuntu 10.04. I had ubuntu 10.10 but I want to install 10.04 (32 bit) because 10.10 is slow. Problems with cd drive/cd caused installation to be incomplete so system cannot reboot at all.

Ubuntu, with Linux 2.6.35-22-generic (recovery mode)
Memory test (memtest86+)
Memory test (memtes86+, serial console 115200)

Which should I select? and what do I do to go on to install/reinstall 10.04?

Ubuntu Installation :: Grub 2 Doesn't Use Boot Default?

Feb 26, 2010

I loaded Kubuntu 9.1 and got a mess in the Grub 2 Boot Menu, which I can't correct.

I get extra choices in the Boot menu, and the first few, which are supposedly for Kubuntu Karmic Koala all put me in a shell, which ends in a black screen, then shows up a shell once I hit "enter". Then I just have a "intramfs" (?) prompt.

So I went into Grub2 to change it, and it refuses to do it. All I get is a screen full of error messages every time I try, with no change. Apparently it is looking to access drive sdb8, which is non-existent. I DO have a drive sda8, though.

So with all the wonderfulness of the indirect system to change Grub 2 how am I supposed to set it right? The old Grub worked fine, and just took simple changes to the menu.lst file.

Can't somebody write a program that lets Grub 2 be changed from within the program, rather than all this running around trying to find what file to change, and how to get the change to work?

Just to be clear, here are the errors as they show up when grub-update is flailing around:
"error: cannot open '/dev/sdb' while attempting to get disk size
error: cannot open '/dev/sdb' while attempting to get disk size
Generating grub.cfg
error: cannot open '/dev/sdb' while attempting to get disk size

Ubuntu Installation :: Can't Edit Grub Default Boot?

May 2, 2011

I think my Natty 64 bit install is missing a dependency for gk, even though it shows up install in Synaptic. I have also tried using Start up Manager and the changes I make there don't show up after restarting either. I just want to change the default boot to number 4, Windows. Any suggestions are welcome, but I have tried all the ones I've found on this forum so far and none have worked, including editing etc/grub/default and saving with sudo update-grub. That's when I get a "gk not found" error.
