Ubuntu Servers :: GRUB Won't Autoboot Without Monitor?
Jul 3, 2010I've installed Ubuntu Server on an old computer and I want it to autoboot as it is intended to be a headless box.I have installed the desktop packages to allow me to use FreeNX.URL]Unfortunately I've already made these changes and it still seems to need a monitor before it will show the boot menu and a keyboard to press enter on the first option.If I restart from within the gnome desktop, it will reboot perfectly. If I use shutdown -r now, shutdown -s now or shutdown -h now and then power it on again, it will display the GRUB boot menu without automatically booting.

Mar 7, 2010My fedora does not autoboot. I get stuck at the grub selection green. I have the choice of one kernel and I have to press enter before I can continue to boot into the OS. Is there a way to fix this? /etc/grub.conf, menu.lst and /boot/grub/grub.conf are all identical. I have tried different timeout # as well as default=saved. Still nothing works and fedora does not count down.

Ubuntu :: GRUB 2 : Difference Between 'grub-pc', 'grub-efi' And 'grub-coreboot'?
Jan 6, 2010I would like to know if there is any differences on how to install and to configure GRUB 2 in the different architectures (BIOS/IBM PC-Compatibles, EFI/MacIntel and Corebbot)? Does the Ubuntu installer automatically recognize the different architectures and install the appropriate GRUB 2 package ('grub-pc', 'grub-efi' or 'grub-coreboot' according to the arch)? Or does it just install 'grub-pc'? Is the location of GRUB 2's configuration files different depending on the arch of the computer? Or are they all located in '/boot/grub/', '/etc/grub/default' and '/etc/grub.d/', no matter the arch of the computer? Are the files' structure and options to configure GRUB 2 ('/etc/grub/default' and the scripts in '/etc/grub.d/') different depending on the arch of the computer?

Jan 3, 2010I'm just slightly confused here, but... what the? Why does installing grub-doc remove BOTH grub-pc, and grub-common? So basically it seems like by installing grub-doc, I have uninstalled grub totally (yes, it is still there as the bootloader, but i have no way of updating it now!) from my system. What's the conflict between grub-doc and grub-pc, such that grub-pc has to be removed?

Software :: GRUB2 - Autoprobe "update Grub" Grub Seems To Detect All OS And Generates Grub.cfg
Feb 28, 2011I have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.
View 3 Replies View RelatedUbuntu :: Get The Version Of GRUB / GRUB-legacy To Boot Any Recent Windows 64 Beyond XP (Vista Or 7)
Dec 20, 2010I'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?
Ubuntu :: Booting From NForce FakeRAID - Hand Correct Grub.cfg After Update-grub?
Mar 5, 2011I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?
Ubuntu :: Grub - Lost My Windows Partition - Can't Find Menu.lst In /boot/grub
Nov 1, 2010I 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 ?
Ubuntu :: Grub Messed Up - Error: Can't Find GRUB Drive For /sdd1
Jan 31, 2010I've trawled the internet but can't seem to find the exact same issue, so I've made a new thread. So, I installed Ubuntu onto a 160gb drive. I have other drives in the system, but I disconnected them so that the system drive would be sda. Ubuntu installed perfectly with no issues whatsoever. I connected the other drives in the system, and again it booted up perfectly (although I can't remember whether the 160gb drive remained as sda or became sdd). Then I attached some extra drives temporarily to do some data shuffling.
This moved my system drive to become sdf. My computer booted fine multiple times like this, but when I was finished with the drives I rebooted and suddenly everything broke. For some reason my ubuntu installation showed up in the GRUB twice, and neither of them booted. So, I popped in the Live CD (which I'm using to type this post), and decided to update the grub. I chrooted into my system drive and ran update-grub, but it simply returned something like this:

Ubuntu Installation :: Grub Errors - More Than 1 Grub - The Change Does Not Appear In The Boot Up Menu
Dec 22, 2010The 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 :: GRUB File Not Found - Change The Path Of The Grub Reader To Sda 5 ?
Aug 15, 2010I gave sda1-2 for windows and sda 3-4-5 on an extended partition for my linux OS. I installed ubuntu on sda 7 (when I go into disk utilities it shows up as sda 7 idk why) alongside another ubuntu on sda 5 ( EXTENDEDPARTITION : sda 5-6-7 ) so I could remove mandriva bootloader.Since I did, I removed ubuntu (sda 7) since it wasn't necessary but after it gave me the grub file not found.Obviously yes, since GRUB was installed from sda 7 but i have another grub.conf on sda 5 and I would like to know how to change the path of the grub reader to sda 5? or must I install all over again de grub loader?

Worse, I think I accidently installed grub to something labelled SDC5.
Cannot get anything except the "grub rescue" prompt. I'm not sure if using the LiveCD (9.10) can help. Have tried a few prompts from other threads but just ended up with mud splattered all over the place. I'm gathering I need to load grub, but can I do it using any grub rescue commands?
