View 3 RepliesI have a 9.10 ubuntu desktop on a tower (bought 2004) working fine, and wanted to add a 10.4 server on an additional partition. After install, I stated grub may be newly written, as the list of os was fine. After reboot I got "grub rescue>" I managed to get the system working again, and now I have a grub2 menu list stating correct entries. But when I select the server entry the boot fails telling "disk not found" (The UUID of the partition given is correct, and also shown when accessing the partition from the 9.10 desktop (this needs an additional authentification when mounting) grub shell command ls does not show the partition, all other tools (life-CD, working installation, gparted etc.) do show it normally, I cannot find any difference. The partition is on the beginning of the disk

I had my HD partitioned with Win7 and 2 versions of Xubuntu (32 and 64 bit). and Grub as multiboot loader. I removed the 32 bit version and assigned the free space to the 64 bit version using the Gparted bootCD, but now Grub can't find any partition anymore at boottime. All I get is this message and prompt when I try to boot my computer: error: no such partition grub rescue. My Linux partition is supposed to be sda6. When using the 'ls' command I get quite few entries, from which one is (hd0,6), which is sda6 I suppose.I can list the contents of directories on (hd0,6).I've tried instrucions from this page, but many commands don't work, like 'linux', 'initrd' and 'boot'.I really don't want to loose my current OS's. Is there a way to recover fom this so I get the Grub boot menu with my Win7 and Xubuntu entries again?
View 4 Replies View RelatedI messed up my mbr by deleting my other drive which I guess had the MBR for both my OS (2 Windows 7's). So i installed Ubuntu in an attempt to fix it all hoping to get the GRUB. It then booted directly into Ubuntu.So I ran bootsect.exe tx the mbr and it said success.Still boots into Ubuntu directly without and grub.

I recently installed Ubuntu 11.04 on a clean hard drive. Everything went well and I ended up giving /home it's own partition. After a while I figured I would dual boot with windows 7 and my mbr got overwritten. Now after this happened I googles how to fix it and found the same answer almost everywhere. It had me go into terminal and run grub an find my partition and setup grub again. All of this was done off a livecd. The only problem was that my livecd didn't have the grub shell installed. Everytime I ran "sudo grub" it would say "sudo: grub: command not found" I tried to install it but it kept giving me errors and I only once actually got into grub, but it could not find my partition. Whenever I typed "find /boot/grub/stage1" it said directory does not exist. So I attempted to fix it my own way. I installed another version of ubuntu along Sid the first. This allowed me to triple boot between the two versions of ubuntu and windows 7. So I booted into my original ubuntu (11.04) and deleted the older version of ubuntu with gparted. I deleted the partition and restarted, but when I restarted I got an error saying that grub could not find the partition. I can boot into my original ubuntu through the ultimate boot cd but it is a round a bout way of doing it. Is there anyway I can set grub to search for ubuntu 11.04 on startup instead of the deleted version of ubuntu?

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.
Just installed 10.04, loving the new theme and default background. My problem is that Grub won't detect my Win 7 boot. I installed it the way i normally do, seemed to work for the last few times. I put in my Windows recovery disc to try and fix the MBR but that failed as the disc wont even see my Win 7 install. I have included my boot info script file.
View 9 Replies View RelatedSo I recently started using Windows 7, but it kept crashing so i thought "OK back to WinXP and Ubuntu 10.10" So I installed Windows (urrrggh) and that went fine, but now that I have come to installing Ubuntu Desktop 10.10, it cant seem to find the Windows XP partition, I tried manually editing partitions but it wouldnt let me resize the partition. But it did give me the option to install the Bootloader (GRUB) to the partition labelled "Windows XP Professional".
I have used this setup before and ran fine, bare in mind that was with 9.10, maybe I should install 9.10 and then use "sudo apt-get install dist-upgrade"?If i cant get this working I will try another distro and see if its Ubuntu or whether its a Windows or disk issue.
I use Windows 7: Home Premium and I have three partitions on my hard disk. Lately I installed Ubuntu NOT on C: (win 7) BUT on D: (size 104 GB). Now, I CAN'T find the drive (D:) on Ubuntu. However I can still find it on Win 7.

Installing 10.10 RC dual boot with Win7. Is there no place in the installer to specify where Grub will be installed? I don't want it installed in the MBR I want it in the partition with / (I usually only create two partitions for Linux / and swap). I prefer to chain load grub from my windows bootloader.
View 4 Replies View RelatedI'm trying to re-install Grub2 on a dual boot (Win/XP & Ubuntu 10.10) system which will not boot. I am following the guide here:

However, the final step results in this warning message: "grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea....."
I guess I agree - that's not what I want to do. Where is the defect in the procedure and how do I overcome it? If I try alternative advice, available in the forums, by using the command
Code:
sudo grub-install /dev/sda
then I receive the error message

I have Fedora 15 installed alongside Windows and Debian. The bootloader found Windows without any trouble, but it did not add an entry for the Debian install. os-prober sees both Windows and Debian as follows:
/dev/sda1:Microsoft Windows XP Professional:Windows:chain/dev/sda5ebian GNU/Linux (6.0.1)ebian:linux
Since I'm new to Fedora and lack experience with Grub2, I'm asking for advice here before I go off and try to repair this in some silly way that will make life even more difficult. So...what's the tried-and-true Fedora approach to this?
I seem to have determined a few other things about my "only gets as far as a GRUB command line" problem:To recap, sda3 (GRUB hd0,2) is the main Linux partition; sda9 (GRUB hd0,8) is the boot partition.GRUB is 0.92.Installation was from an 8.04LTS live CD (at least, that's what the envelope says it is)/"/boot/grub" (i.e., "/grub" on sd9/hd0,8) contains a "menu.lst" file. I modified it (had to do a "sudo gedit" from a command line!) to (1) comment out the line that hides the boot menu, (2) change the timeout from 3 seconds to 90, and (3) add a menu line based on my succesful manual IPL of DOS.
It still boots to a GRUB command line. If I do a "configfile /grub/menu.lst," a boot menu comes up. DOS will successfully IPL, but Linux still gets a "no setup signature found," (ditto for "recovery mode"), which suggests either a bad kernel, or a kernel that's too big for the GRUB to handle.Why would it be finding its way to grub, but not finding the boot menu file?Why would the live CD come up just fine, yet the GRUB and kernel it installs fail?
I am running Ubuntu 10.10. Normally when I boot, I get the choice to run Ubuntu or the Windows loader, where I choose between 7 or XP. I have just noticed that when I boot now, I do not have the choice of going into windows. This has happened on two of my PC's just in the last few days. I assume one of the updates has overwritten the grub configuration file as I still get the grub menu but not the windows option. I have tried sudo update-grub but this did not solve the problem.

I'm running Ubuntu 11.04 on my Acer extensa 5620. I need to install windows and setup a dual boot on this machine. Here's what I did. I followed the instructions on this page

and resized my home partition (which is differenet from the file system partition). Anyways, I resized the partition and made a new NTFS partition. This was all done from Live CD. I then rebooted and then tried the windows installation CD. Now here my problem crops up.
Windows says that no partition is found. What have I done wrong? Any ideas? Can the drive be damaged or have I made a mistake some where? I did not specify a mount point for the new NTFS partition, does that matter?
I have messed up my partitions really bad and grub refuses to install. Here's how it looks:

Initially there was only Linux (Karmic) on this hdd, on what is now sda2 to sda6, current sda2 being the boot partition. Now, I decided to install Windows XP and using GParted I created an NTFS partition at the end, sda7. But it wanted to have his loader on the first one, so (now this is probably stupid what I did) I cut 100MB from Linux root and put it as NTFS at the beginning, making it sda1, boot and letting windows install it's loader there. I figured I can just reinstall grub on it later (think I have missed some tutorials). As you can probably guess, it won't. I formatted sda1 to ext4 now. What I do is run the Live CD (9.10), use terminal, then do
Code:
sudo -i
mkdir /media/boot
mount /dev/sda1 /media/boot
grub-install --recheck --root-directory=/media/boot /dev/sda1
and it goes
Code:
grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea.
grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged.
grub-setup: error: Cannot read `/grub/core.img' correctly
also, when I do update-grub it says "grub-probe: error: cannot find a device for /."
I tried installing grub on sda2 and flagging it as a boot and still no-go.
I was defraging windows xp and the power want off now I can only boot into ubuntu from Grub.

I had a dual boot system(WinXP and Ubuntu). But something happened and I was not able to boot into my Ubuntu partition. It gave GRUB missing error. I tried reformatting the dedicated 40 GB ubuntu partition to NTFS and again try to reinstall ubuntu. But now, when I install ubuntu through boot time install, it shows that my whole hard disk is empty( but I have windows XP on whole hdd at the moment) and do not give any other option but to use whole hdd.
Alternatively when I try to install it inside windows, then after rebooting it shows, no root file system defined error and neither gives any option to do so also ( this method worked earlier o my PC). At the moment, It still shows ubuntu and windowsXP at OS choice menu at boot time but when booting in ubuntu, it shows GRUB missing. (I don't have any ubuntu installation on my hard disk at the moment).
So I am experimenting with other linux distros.....I just installed a small partition with OpenGEU, the one still based on Ubuntu.....now it wont recognize Mint. Ubuntu Studio is next on my list, but before I invest any more work I want to make sure I can add more partitions to grub, not just the most recent linux partition...
I think that future distros of linux should have a fix for this....if you install linux it should detect every other operating system on the disk, not just windows plus the most recent linux install.
install /boot separate? I always create a / and /home partition but never separate boot. Does that make life easier?

Ok, Grub 2 is very powerful, maybe it's the lagging documentation, or lack of tutorials that is the problem. But I don't know how to fix this. Do I start over without the /boot partition? Do I bail on ubu?
