Ubuntu Servers :: Grub Always Installs On 'first' Bios Disk?
Apr 9, 2010
I was installing Ubuntu 9.04 64bit server from the CD on a machine that I normally run ESXi on. I wanted to test disk speed on a direct install vs. the install in ESXi, so I installed a 4th hard disk, shutdown ESXi, and installed Ubuntu directly on the new disk (4th Bios disk - SCSI:3 or sdd). When I tried to boot from this disk, nothing happened. I rebooted from the ESXi install disk (SCSI:2 or sdc), all was fine. Playing around, I finally found that to boot the ubuntu install, i had to boot from SCSI:0 - Grub had installed there, even though I never indicated that disk for anything during the install. It would be much better if Grub ASKED where it should be install, rather than assuming.

I recently bought a new Gateway desktop. I use mostly Ubuntu but like to boot into Windows once in a while. Have used Ubuntu as my main OS for about 3 to 4 years, dual booting. After the Ubuntu 10.04 release, I decided to throw in another hard drive into the new computer and make it dual boot.
Mistakes:
1. I did not create the Gateway Recovery Disk in Windows before installing Ubuntu.
2. Installed Ubuntu 10.04 without disconnecting the Windows 7 drive.
3. The Ubuntu install never prompted me asking where to install Grub (apparently there is an advanced menu somewhere in the install process that lets you select), and it was installed to the first drive on the PC by default, which happened to be the Win 7 drive.
This left the Windows 7 unbootable because it did not appear in the Grub menu. I did some searching and managed to install Grub on the second drive (the one with the Ubuntu install) and also managed to add Windows 7 to the Grub menu so I could boot into Windows. This last procedure added the Windows 7 option to the Grub on both drives.
I then managed to fix the Windows 7 mbr using /fixmbr and /fixboot. The problems I still have are as following. I can't create the Windows Gateway Recovery Disk in Windows. Every time I try, I get a message telling me "Hard drive configuration is not set to the factory default. Restore aborted.". I already disconnected the Ubuntu drive but get the same results. I know this one is not a Linux issue, but maybe someone had a similar issue and might be able to help.
The next problem I have is that it looks like after the las Kernel update in Ubuntu, Grub overwrote the Windows 7 mbr again. Is there a setting file somewhere that now tells Ubuntu that Grub is installed in two places and that whenever there is an update it updates both? Can I change this? I really would like to avoid re-installing Ubuntu to fix this.

Is there something I can do to get a Linux Distro to install right the first time. I have the same types of problems with Mandriva Ubuntu and Fedora over and over again but not with a OS you pay for. Is it time for BSD?

I have an Ubuntu Server on (8.10) running under Citrix XenServer (though that shouldn't make a difference).
I installed on a single disk:
xvda1 - 200 MB - /boot
xvda2 - 9.8 GB - LVM (ubuntu-base)
The LVM is:
swap - 1.0 GB
root - 8.8 GB - /
I have successfully gotten this converted to RAID1 by adding a new drive (xvdb) and following the Debian howtoforge article [URL]
What I have not been able to do, is get grub working properly.
If I fail xvdb and reboot the system, everything comes up and I can reboot and run.
If I fail xvda and reboot the system, XenServer gives me a bootloader error. i.e.: no grub
If someone has done this, can they tell me what grub commands to run to get a successful boot of the primary disk fails?

I am trying to install Fedora 13 on a new system from CD. DISK 1 runs but terminates without using disks 2-5. There is a system I can access as 'root' but I was not prompted to create a unique user or which packages should be installed.How do I complete the process?

I have a client who asked me to setup two seperate installations of Ubuntu on his system for him; the intention being that he would have a fall back strategy in the event he screwed something up with the primary install. We have two seperate partitions set aside for each respective distro's / (root) and a large partition that both OS's mount as /home.
Thinking about this just now I have a feeling that what I should have done was added one more tiny partition to house /boot for both OS's. Would that have been the best thing to do? What is happening right now is both / partitions have a /boot folder and the MBR is mounting the secondary /boot folder (from Ubuntu #2) to run GRUB at the startup. The menu list of this /boot folder is giving priority to the instance of Ubuntu we had intended to function as the backup because the size of it's partition is much smaller. Well anyway, I'm going to guess the best way to fix this is to have a /boot partition that both OSs can share, but I don't know how to change the current configuration for both systems to do that.

In Ubuntu Server 10.04, the kernel naming convention went sort of like "vmlinuz-2.6.32.21-server" for servers and "vmlinuz-2.6.32.21-generic" for desktops... Kernel numbers changing for the kernel version, but last signifying whether it was a desktop or a server version of the kernel... Right? At least as much as I've noticed with my 64bit installs.
I recently got a 32bit test server up on Ubuntu 10.10 and I think I'm either confused, maybe things might be different in 10.10 versions or my prior assumptions were wrong? On this test machine, I installed Ubuntu Server 10.10 32bit. After the install, I upgraded packages, then I installed kubuntu-desktop, xubuntu-desktop and ubuntu-desktop (in that order). I know the implied resource and security issues-- but this was a test machine to work something out. My observation on this machine is that I cannot find a kernel image on it with "...-server". All the versions of kernel images are "...-generic" All my previous installs of Ubuntu Server have been 64bit installs... and I just assumed all server kernels had "...-server" as the naming convention.
- Is this different for 10.10?
- Is this a difference in the 32bit server/64bit server kernel?
- Did my installs of the GUI's somehow change to the desktop kernel? If so, all my testing in now invalidated- as I'm supposed to be testing on the "server kernel."

Anyone here knows the OpenSuse install CD runthrough? I am using DELL pc's, and remember installing Linux as being a few almost basic steps on my self assembled clone pc's in my youth. Now, over ten years later I want to redo that and return to my old playground. I am using after over 12 years administering MS stuff again applications running on unix (solaris) at my work. Its like homecoming but in a difficult way, I am brainwashed and not really into unix anymore. So... lets install linux again at home. Returning to my favorite Suse distribution in the old days (who knows why).
I went through the installation (Opensuse11) simple, standard to start with, so mainly next (ACPI disabled). Rebooted... and the pc finds no recognized bootable HDD. OK, well, try again, other HDD to be sure, results in the same. Set manually the root partition as active. No go, I feel as a newbie again. What happened to me in those last years? Tried to do it also with a fedora distri - same outcome. When plugging these HDD in another recent (DELL) pc, it also does not recognize the HDD as bootable. Both disks have been part of a system before and functioned; until I changed this system for this other purpose. Probably i am missing something basic??

I'm dual booting Win7 & Ubuntu 10.04 on a Gateway NV78 series laptop, and while on the Windows side, the Gateway Update Manager asks to update my BIOS. If I allow it to do so, will it mess up Grub? For bonus points: how could I fix Grub if the BIOS updates does damage it?

I'm having some issues getting Ubuntu to boot. I've installed it a bunch of times before, but dual booting and not. Right now though, I'm having issues installing it along with Windows 7, on separate hard drives. Here's my current configuration:
60GB SSD with windows 7
500GB HDD, NTFS, windows 7 data
I bought a 1TB HDD that I want Ubuntu on, but I only want Ubuntu to use 100 GB. I want the other 900GB for Windows 7. So, I put in the Ubuntu CD, chose to edit the partitions manually in the 1TB HDD, created a 100GB ext4 primary partition for linux and a 2GB swap partition, leaving the other 900GB unallocated. Ubuntu seemed to install fine, said it succeeded, and asked me to reboot. When I did, however, my computer boots straight into Windows (no GRUB screen at all). I've tried changing the boot priority to all three of my installed drives from BIOS and tried putting GRUB on both my SSD and 1TB HDD.

When I boot, I can grub into linux, but when I try to boot windows it doesn't work.
It shows a screen where it lists the commands:
However, if I change the harddrive boot order in bios I can easily get back into windows by selecting that harddrive for the first slot.
However, I don't want to do this everytime I want to switch operating systems.

I have decided to try to run a web server, with a view to possibly, eventually, hosting my own website.To test the water I downloaded ClearOS and SME Server with a view to installing on a spare partition and trying them out.But, both installers seem to require the whole HDD to install into. Both installers have a warning saying that all partitions and drives attached to the PC will be erased in order to 'initialise' the HDD.
I must've installed 100 linux distros and i've never seen this before, including CentOS 5.5, which ClearOS is based on.Why is this the case? Is there any way I can install alongside another linux installation?? I have tried vbox but it doesn't offer a proper sandbox really as there is only one NIC.

I'm attempting to install F13 on a server that has a 2-disk RAID setup in the BIOS. When I get to the screen where I select what drive to install on, there are no drives listed. The hard drives were completely formatted before starting the 13 installation. Do I need to put something on them before Fedora will install?

My problem, GRUB loader appears when it normally did not and Ubuntu fails to boot. My story, I installed ubuntu on a HP Touchsmart laptop a month ago because I was having troubles with Windows and... well I just wanted to install ubuntu. All goes well until a week ago when my sound was permanently muted through a hardware switch and ubuntu was not detecting it. I tried hitting the button on my laptop but nothing worked. Soo... I tried resetting my BIOS in hopes that it would fix it. I set the bios to its defaults and booted. This is where it got weird. the GRUB loader appeared when it normally did not and upon booting, a black screen with flashing cursor would show up and then... nothing. I changed the bios settings back to what they were and still nothing.
I have removed the silent boot from the GRUB boot line and can see whats going on... a little, the last thing it shows is "Running /scripts/init-bottom ... done." annnd nothing else. When booting in recovery mode it stops after 30 or so seconds on...
Code:
ACPI: Power Button [PWRB]
input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/inp
and just ends on that line. the previous line shows closing the Lid as a button.
I have tried booting into a live USB (as the laptop has no cd drive) and everything works fine.
how the BIOS would be related to GRUB/booting..

I just upgraded from 9.04 to 9.10 (using Update Manager) in an attempt to get to 10.04. Installation and upgrade seemed to go OK until reboot. Now I only get a black screen - I don't see the grub menu, I don't even see any way to access the BIOS menu- not even a blinking cursor. I can hear it start and I can see the numlocks key go on. Ctrl-Alt-PrtScrn-B does not reboot (nor does Ctrl-Alt-Backspace- but I didn't expect that would) Surprisingly Ctrl-Alt-Del does (or at least it sounds like it does) reboot the system. I do have a NVIDIA cards and after reading around I suspect that this is likely the problem but I have no idea what to do now..
Here's what I've attempted:
I figured since I wanted to get to 10.04 anyway and this was so troublesome I could just go do a fresh install with a Live CD or USB to 10.04. However, even with a live CD or USB I still just get a blank screen.
Continually holding down F2 (and other function keys to try to access Bios)
Holding down Shift while booting
Esc while booting
Moving the monitor to the VGA port (as opposed to the NVIDIA card).
Other information...
Previously I had tried to upgrade to 9.10, but ran into problems with it not recognizing my RAID, so I just found it easier to go back to 9.04. (So although this is likely a graphics problem I guess the possibility is that now it doesn't even see my boot drive- although- if that was the case, I'd assume I wouldn't have the same problems from the CD or USB boot.) My ultimate goal is to get this to 10.04, if I could do it with an upgrade instead of a fresh install I'd prefer that, but at this point just getting back to a functioning computer would be ideal. I see many options in other posts for how to get back once you can access a command line- but since I can't even see that, I'm not sure what to do now.

Is it possible to install GRUB in the MBR of the only bootable disk in the system, but load configuration and images from another disk?Basically I want to install GRUB on /dev/sda, but menu and images will be under /dev/sdb2.Note: /dev/sdb is not bootable.

If I use the super grub disk I can get to my ubuntu partition otherwise my windows partition boots automatically. I spent over an hour in the community documentation using the live cd to reinstall grub and nothing has fixed it. I think that grub is installed and the windows bootloader is just taking precedence.

Is there some workaround by changing grub settings other than rewiring the hard disks or changing in bios..
1. my bios is getting reset (low battery)
2. my hard disks are sata and ide, so the ide one is loaded as hd1 by default, cudn't find any way to change that..

I've been running 10.04 server for 3 months from a fresh install. I have been installing updates while Bind9, Apache2 and Samba worked just fine. The last time I installed updates was 3 weeks ago and it worked just fine.
Today I ran into problems where the system stopped doing its DNS stuff and wouldn't respond to pings over the network. Since I couldn't get it to respond with a keyboard and monitor attached to it I shut it down through the power switch. I then tried to restart the machine and all it would do was go through the bios and show a cursor flashing in the upper left or this odd color pattern on the screen and then reboot
I have tried pulling the HD and loaded it into my Ubuntu desktop and loaded the file system just fine. I then tried using the "rescue a broken system" option Ubuntu 10.04 32bit install disk and it seems to just sit at a flashing cursor.
I've seen some odd things pop up on the screen at times but mainly would be a flashing cursor in the upper left part of the screen.

I have an SiI hardware SATA RAID card, with two 500GB disks in mirrored RAID configuration. When I first plugged them in and set it up, things seemed to work ok, but on boot the raid controller told me that the RAID needed rebuilding, and it would happen automatically after POST. So I didn't worry about it, and the drive mounted fine, and it's been that way for years. I just went in and manually on-line rebuilt the RAID in the controller's BIOS, and now when I boot into Ubuntu, both disks show up in fdisk, but neither show up in /dev/disk/by-uuid. Am I missing something?

I have Debian Jessie 8.0 amd-64 installed. It is a dual boot system with Widnows 8.1 alongside. Both the systems work fine with a few glitches coming at times on jessie. But I assume it should get stabilised with time.
Problem is:
The usb keyboard is no longer detected until the GRUB stage crosses.
* This implies I am unable to press F2 to enter into BIOS
* I am unable to chose Windows 8.1 by using arrow key on the keyboard.
When the default system (first in the grub list), in this case Debian is selected after time runs out then the keyboard comes back to life and works properly thereafter.
So far I have tried the possible solution given at [URL] .... but it did not work.

I installed Puppy Linux on a partition on an older 2000-era computer. The other partition had Windows ME, which crashed and burned recently. Lately, the computer has started to open GRUB very slowly. It is also slow to boot Puppy Linux from there. I reinstalled GRUB, to no avail. I decided that the problem was probably a slow BIOS, but I'm not sure. Does anyone know of another possible problem, or of a good boot-disk BIOS diagnostic tool? I tried using a couple of the tools on the Ultimate Boot Disk, but they all got hung up, displaying: - InitDisk as the last line in the sequence.

Well today I decided that I couldn't wait for the offical release of 10.04 LTS, so I upgraded from 9.10 to 10.04 LTS Beta 2. After realizing that many problems had come with that update, I decided to just format my Ubuntu partition and reinstall it. Somehow my GRUB stopped working from when I formatted Ubuntu, so I whipped out the old Toshiba recovery disk for Windows Vista 32bit. After many attempts to have the recovery portion of the disk fix all of my problems and seeing no results, I decided that reinstalling Ubuntu (and GRUB) might make everything all better. Well it didn't. Grub shows my Windows partition but fails to boot it. After selecting it, it goes to a blank screen and stops responding. And to add to all of my problems, my BIOS has changed slightly. It no longer shows/or responds to F2 or F12 when I tried to give another try at that Toshiba recovery disk. That kinda sucks since I can't choose what to boot. Please help me!! I really don't want to have to format my entire hard drive and try to install Windows Vista again (Not that Vista is anything anyone should love) I have many expensive programs that can only be activated a certain amount of times. I don't even think that I could reinstall Vista since my BIOS won't let me boot the CD/DVD drive.

I'm currently setting up a dell server with hardware raid 1 on sas 6r. i got 4 sas installed on the server and configured to raid 1 as stated below,
array 1:
slot 0 & 1
array 2:
slot 2 & 3
during the installation, the installer detect the array 2 as sda and array 1 as sdb.. so i proceed with installation on array 2. after completed the installation, the first reboot lead me to a 'grub-rescue" prompt. by following the guide at url Mode, i've noticed that the boot folder has changed to (hd1,1), which i believe it has changed to sdb1. default root device shows that prefix=(hd0,1)/grub.
