Just got done installing U 10.1 into my old Dell desktop. Since I'm pretty darn new at Linux, I'll do my best to explain. Upon selecting Ubuntu to boot, I get a 'grub>' prompt, much like C: in DOS. But, at this point, I haven't the slightest idea of what to do.
View 3 RepliesI 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 recently attempted to install Debian 8 on my iMac (late 2011). I partitioned my drive using disk utility to create FAT partitions (100GB for Debian and 2GB for SWAP) and installed rEFInd to boot into Debian.During the installation process I selected the drives I partitioned and set the mount points for each as / and swap.
Everything was fine and installation was successful and was prompted to restart to set up Debian. However when I did Grub did not recognise the Bluetooth keyboard. Unable to do anything it started the "Debian GNU/LINUX option" and loaded into what seems to be the grub prompt/terminal with the following displayed in bold:

So I wanted to get rid of ubuntu 10.10 on my HP pavilion dv6 laptop as I wanted to make some hd space. Its a dual boot with windows 7. I deleted the ubuntu partition and expanded the windows partition to fill the whole hard drive again. When I restarted my laptop I got the "error: no such partition. Grub rescue>" message.
I tried inserting my ubuntu 10.10 boot cd but whenever I boot from the cd I get the exact same grub rescue error. Is it possible to remedy this situation from the error? I am currently unable to download a windows recovery cd so I'm stuck in the grub rescue page unless its possible to fix this mess from the error prompt.
After certain system-wide changes, like kernels updates, I obtain grub prompt on restart. However, if I put the hard drive into another computer (b), it boots up fine. Since, however, I use the present computer (a) regularly, I only use b to purge and reinstall grub using the chroot method. However, doing so every time is time consuming; and I cannot change anything in the defaults and run update-grub without obtaining a grub prompt on restart. How do I fix this?
View 9 Replies View RelatedI've got myself the curious situation where, when I boot the system, I can get grub to start, but it always drops to the prompt.
I can run:configfile /grub/menu.lst
and this brings up the menu with no problems, and from there I can boot the system to either linux or windows. What I don't understand is why it wont go to the menu in the first place?As far as I can tell, grub/Kubuntu got confused when installing, as each of the hd#,# settings in the menu.lst have needed tweaking to let the system boot. (e.g. windows is actually hd0, but the original install had it at hd2. Likewise linux is on hd1, but the menu.lst had it at hd0). I've happily tweaked these to make the system boot, but would appreciate any help in convincing grub to actually load the menu without me having to use the prompt.
I have been trying ubantu 9.10 via dual boot (with windows XP) for a while now. Today I decided to wipe out windows and install ubantu only.

View 6 Replies View RelatedI am a casual user of Ubuntu, which is installed in a vmware virtual machine. After upgrading to Ubuntu 11.04, and after the reboot, it just booted up to a grub prompt.
I found a useful post about resolving this problem here: [URL]
The sequence of grub shell commands to be entered are these: set root=(hdX,Y) linux /vmlinuz root=/dev/sdZ ro initrd /initrd.img bootwhere the X, Y, and Z are replaced with appropriate letters/numbers.
The problem that I am having is that TAB is not completing the commands at the grub shell, thus I have no idea what the letters/numbers to use.
My installation is completely generic - I have not customized it in any way. check their vmware/Ubuntu system and let me know what letters/numbers to use.
I rebooted my computer recently after installing some updates in Ubuntu and now when grub launches it goes straight to the grub prompt and I don't get a menu. I tried searching around online and have tried what seemed like the most common fix but to no avail:
find /boot/grub/stage1 (returns hd1,0)
root (hd1,0)
setup (hd0) -I also tried (hd1,0) and (hd1)
-then reboot- (still get no menu and goes straight to the prompt)
I then tried booting into Ubuntu live, using apt-get to install Grub, and then running through the install process using similar commands, but to no avail. When I run setup it finds my config info and doesn't show any errors. I have a menu.lst file with lots of entries for different kernel versions and a windows 7 install on hd0,0. I am running Ubuntu Ubuntu 10.04.1 LTS, kernel 2.6.32-25-generic-pae.

I'm having a issue. It first started a few nights ago, and after booting from the live cd and reading around, I saw it mentioned somewhere that it might help to update GRUB. I did this using sudo update-grub. This took care of the issue, with an unexpected, but not altogether unwanted result: instead of having to choose a temporary boot device to boot on to the external drive Ubuntu is on, I got a grub menu which showed the the OSs for both HDDS. I thought all was fine, but a few days later, same thing. Updated grub again, and all was okay. Tonight, it happened again.
When I try to update grub now it says:
Code:
ubuntu@ubuntu:~$ sudo update-grub
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
Here's the result of the boot info script.

I installed 9.10 with wubi and lately I had a boot problem with the result is that it boots to a grub prompt. I tried several commands, but no success. I thought I hosed the system. [URL]. Once I copied the new wublidr file over, that did it! Give it a shot, as it works.
View 1 Replies View RelatedI just installed Ubuntu 9.10 on hd1 - /dev/sdb1 at the end of the installation I chose to install grub at hd0 - /dev/sda1. The file system I chose was ext4 for ubuntu "/" - 50 GB,
ext3 for "/home" - 5 GB, and 1.5 more for swap. When the installation was complete I got the following prompt:

There was nothing I could do, pressing TAB did not show me all the commands like grub is expected to. Typing 'help' did not show any commands as well, instead it showed me - "NO SUCH COMMAND" or something like that (I did not took note of what the output was). I believe the problem is in the grub loader - which was not really installed properly in hd0 - /dev/sda1 (which is FAT32 - windows)
Two days ago I decided to migrate from Fedora to Ubuntu 10.04. On the Ubuntu install I chose to format the entire disk as I do not want a dual boot system. I have three disks and have set the bios to boot from dvd, then main disk, then 2nd disk, then any other bootable drive and coming from a working Fedora I know I have my "slaves" and "Master" pin positions on the disks set correctly.
When I try to boot the fresh install of Ubuntu I do not see any menu options, no boot image nothing, I get taken immediately to a grub command window and I dont know how to fix things from there. I have tried to fix things by booting into the "try before you 'buy'" thing on the installation cd and I can see that Ubuntu has been installed on the main disk, but all in all Im stuck.
i have dual booted ubuntu with windows. but after a few days i realized that ubuntu was too slow for my system and then decided to uninstall it and planned on installing it later. So i deleted the partitions on which ubuntu was installed. I rebooted the system and the grub rescue promt appeared, i already knew the work around was to restore the windows MBR using the live cd i used to install ubuntu or the Windows installer. But the main problem is my DVD suddenly stopped working . So my question is, can i boot windows using the promt? is there any commands? or can i uninstall grub using the rescue promt?
My desktop has been down for more that two weeks
Ubuntu version: 10.04
So I had Ubuntu Server installed and I decided to make some new partitions using gparted via a live usb of Ubuntu desktop. And so I think messed up pretty badly. Ubuntu Server won't boot and I get the following error followed by a grub rescue promt:
Code:Diskette drive 0 seek failure
error: file not found grub rescue >
To me, it seems like some boot files may be missing if not the whole system. After I made the partitions, the live USB of Ubuntu was still working fine until I rebooted.So here is the bigger issue, I figured I would just reinstall everything all over again, but instead I can't.

i am a newbie to linux and i am stuck at the GRUB rescue prompt at the startup.i have dual boot windows and Ubntu 10.04.I want to remove GRUB2 from Harddrive itself.can u suggest ant command on GRUUB recue prompt ?
View 5 Replies View RelatedI have two hard-drives. The first, C: (sda1) has Windows 7 x64 installed on it. The second hard-drive, D: (sdb1), was partitioned when I installed Ubuntu 10.04 into two separate partitions: NTFS and Ext3.
I wanted to remove the Ext3/Ubuntu partition and reclaim that space (i.e. completely remove Ubuntu). I did NOT install using Wubi. I booted up Win7 x64, went into Disk Management, right-clicked the D: partition corresponding to the Ext3 filesystem (shows up as unrecognized in Disk Management), and opted to delete the volume. I then right-clicked on the NTFS D: partition, and opted to Extend the Volume to reclaim the previously partitioned space.
When I rebooted, I ended up with the following error:
Code:
error: no such device: f81368be-ea53-43d2-b8de-bb52b5ac322c.

I cannot get beyond this screen. Rebooting always puts me at the grub rescue prompt. I have looked at the HOWTO: Purge and Grub Rescue Prompt threads, but was not able to understand the instructions and am therefore asking for your help. However, I was able to install the boot script as those threads suggest, and here is my results.txt:

I have installed BackTrack 5 and I have set GRUB up:
Code:

setup (hd1)
However, the GRUB prompt appears at boot instead of the GRUB menu. However, when I boot from the Live USB, the GRUB menu works fine. Here are the contents of the grub.cfg:
Code:

# DO NOT EDIT THIS FILE

# It is automatically generated by /usr/sbin/grub-mkconfig using templates

The reason I want the GRUB menu to show up of because I would like to dual-boot BackTrack 5 with Windows 7.
Recently I messed up GRUB boot loader in my laptop installed with Ubuntu which resulted in grub rescue prompt. So I had to boot Ubuntu Live CD to get it fixed. Thought of blogging it, may be useful for some one.
This fix involves two steps. First one is to chroot into Ubuntu installation partition. Second one is to install the grub MBR (Master Boot Record). I am using Ubuntu Lucid 10.04 and Live CD also of same.

I tried to install Ubuntu as a dual-boot on my Windows XP machine, using the USB stick trial OS and automatic installation. My screw-up came when I left my external USB hard drive plugged in during the install, and as far as I can tell, Ubuntu was installed on that as opposed to my internal HD. Now when I try to boot, I get knocked straight to the grub rescue prompt with an error message that basically shows my "no such device (my external's ID)" -- assuming that the MBR (which I know nothing about editing) is trying to boot off the external that isn't actually enabled until an OS starts it up, and dumping me at the rescue prompt when it can't find it.
I can still load up the trial Ubuntu off the original USB stick (though can't get online with it without wireless drivers), but that's as functional as the computer gets right now. And I don't have a Windows Setup CD anywhere (using a rooommate's Mac at the moment with a terrible European keyboard on it). So is there any way to edit the MBR or something to tell it to boot my regular XP off my internal HD, at which point I can re-partrition and try this whole thing again, or otherwise remove the failed install of Ubuntu through the trial-stick or... well, I'll leave the suggestions up to you all. I've been working on this since about 4am last night and my brain is kind of fried.
Installed 10.04 on my daughters laptop from within windows Vista. All went OK but I had two boot loaders, i.e. turn on laptop and I would get the Windows loader asking if I want to boot in to windows or Ubuntu. Upon selecting ubuntu I would get the standard grub loader that I have on my PC. Did an update a few mins ago and it asked me to update grub which I did and as there was only one disk showing clicked forward. Now on reboot I have grub rescue prompt, no such device. Hard drive is a single 80 gig drive with windows on one partition and ubuntu in another. Have the live cd so can boot from that I guess. What do I do next?
