Ubuntu :: How To Boot "automatically" (without GRUB)
May 18, 2010
I would like to have "only one" operating system to be installed, and that's "Ubuntu".
So as I have only one operating system installed, I "don't need" the GRUB boot-loader to appear at the computer start to choose an appropriate operating system.I want to achieve something similar as when I had only Windows - after the computer start, Windows started automatically - so I want the same with Ubuntu - "after the computer start, Ubuntu should boot automatically" - is this possible?P.S.:Of course, when the Linux kernel is updated, I want "that new kernel" to boot.

I am having trouble getting grub to automatically boot into ubuntu server. When I turn on my server the grub menu shows up and shows me the choices. They all work fine except that grub wont automatically select one. This wouldn't be too much of a problem but this is a headless server and I can't boot into ubuntu without a keyboard. I tried looking through the grub 2 documentation but nothing seemed to work when I edited the conf file.

I have used CentOS for a while and have never run into this issue. I searched all over and didn't see a similar issue anywhere, I did an install of CentOS as a server (no GUI) with only the base. Partition is /boot ext3, size of 100MB. The rest of the drive is partitioned as / with ext3. This is being done on a CompactFlash card of 32GB in size. The BIOS sees it as an IDE drive.
When the install completes and the system reboots, the grub stops at the grub> prompt. There is no menu for OS options. If I do the following commands:
grub>root (hd0,0)
grub>kernel /vmlinuz-2.6.18-194.el5 root=LABEL=/
grub>initrd /initrd-2.6.18-194.el5.img
grub>boot

I am running a dual-boot with Ubuntu (10.10) and Windows 7. Recently I edited my /boot/grub/grub.cfg file to only show one version of Ubuntu (as opposed to several kernel versions) and Windows, simply by commenting out all other menu entries. My question is if I can edit GRUB to just boot a specific entry automatically.
I tried removing all other menu entries, but GRUB still showed the menu with only one entry. I've also considered just setting the timeout to either 0 or 1 second, as this would basically achieve the same thing.

I just want to ask if there is a way to make grub bootloader automatically boot to ubuntu every start up. And only make the bootloader appear when I press a certain key(ie. F7) so that I can boot to windows when I do not want to boot on Ubuntu.

I have read some stuff but none seemed to work such as putting default=saved and in the window (other) section putting savedefault. hmm I know I can just specify the number after default but that breaks when a new kernel is installed. so any way to always make windows the default choice (so my wife will stop moaning

I installed opensuse 11.2 today on my external hard drive and everything is running great, but I want to see if I can make a modification to the way my computer boots. I share this computer with others and they are not going to be happy to have to wait for the boot menu to start when they turn on the computer in order to choose which OS to run (Especially since if they do not make a choice it auto runs opensuse after a few seconds).
What I would like is if opensuse can be "out of sight, out of mind" and only load when I put in the live cd and then choose to boot from my external...... is it possible to do this?I am not a computer wizard and do not work in the industry.

i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

I can't even begin to type how angry I am. (mainly at my inability to do something for myself) I tried to cleanup Grub 2. I heard Start-up Manager was the safe option. I installed it from Synaptic opened it up, it didn't offer me any way to cleanup my boot menu so I closed and uninstalled it. What I do remember is it has a default OS option. I dual boot with Win 7 (for school and work). When I restart my computer it now goes automatically to Ubuntu. I don't even get the option of choosing.
I've tried several guides, lost and recovered grub 2, and now I'm stuck with the same problem 2 hours later. This is the one I thought had the best chance of working, but no luck[URL]..

I installed Ubuntu as a dual boot to play with a while ago, but I really don't have time to be testing it right now, so I'm wanting to set the GRUB menu to automatically pick Windows 7 instead of me having to hang around waiting for the menu to pop up and hitting the right buttons when I'm barely conscious.
Someone linked me here: [URL] and I found the menu.lst file, but when I opened it to edit the default, it was blank ... is the file elsewhere now or something? Do I not have access rights to the file? What's going on, what do I do?

I'm sure there is a thread on this somewhere, but after looking though the first 100+ search results, I can't seem to find it.
After a kernel update today, I noticed that new kernels are not being added to my grub menu.lst (so consequently, I was running an older kernel).
Any obvious reason why this would happen (kernels being installed normally, with yum update)? I thought the whole process was supposed to be automagic.
Would it have anything to do with the fact that I just kept my F11 menu.lst, and added a F12 kernel to it when I installed F12 (to a separate partition), then eventually (today, finally) removed the f11 kernels from it?
Here's my menu.lst, in case it's useful:

I'm trying to automatically remove some of the old GRUB entries that pile up after a few updates and just want to leave live 2 or 3 there along with my Win7 entry. I was looking and saw that there is a utility for Ubuntu but I couldn't find anything for Fedora.

How can I uninstall grub? I have have dual boot between Gentoo and Ubuntu and I want to use the grub, that is on Gentoo partition, as its my main system. I would not care about it as it takes almost no space, but Ubuntu automatically restores its own bootscreen after updates. This is annoying... How to get rid of it?

I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I've been using Linux for over a decade, so no need to worry about the obvious. I'm positive that I have my partitions/install correct. What has me baffled is that Fedora 14, which uses GRUB 0.97 (GRUB legacy) - boots Windows flawlessly every single time on the same hardware, but Ubuntu's (or the upstream Debian's) GRUB legacy do not - even though they are based on the same upstream code from the GNU Savannah servers.
No matter what I've tried I cannot get the Debian or Ubuntu version of GRUB/GRUB-legacy to boot any recent Windows 64 beyond XP (Vista or 7). All that it does is resets the computer when Windows attempts to boot, without an error. GRUB is notoriously difficult to compile, so before I try to compile code from RedHat's archives - any thoughts,experiences, similar issues - whatever?

I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?

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).

I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:

I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.

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?

I am running 10.04 and when I installed Nvidia 3d driver the fonts in a non GUI terminal ie. contol-alt-F2 are very large. I used to be able to alter the font size in /boot/grub/menu.lst but cannot do the same in /boot/grub/grub.cfg.

I installed Ubuntu recently and for various reasons need to install Windows 7 on the same machine. The problem is when I pop in the windows installation disk and restart the computer, it doesn't automatically boot from cd but instead just loads Ubuntu. But when I pop in the Ubuntu installation disk, then the computer automatically boots into that disk. This computer shows no BIOS screen, and I tried entering all sorts of f key, del and esc combinations and nothing brings up the BIOS. So I can't change boot order from there. How I can boot into the windows 7 cd?
