Ubuntu Installation :: Grub Cmd Prompt Appears On Boot?
May 11, 2010
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.

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?

My dell machine has the following: A raid 0 SAS config with Windows 7 installed in one partition, and ubuntu in the other partition. Then two seperate sata hdd. The raid drive is set as first boot, and Windows views it as disk 0 and boots just fine. When I installed ubuntu 10.04 on the second partition, it viewed the disk as sdc. And when booting off the raid drive,im not given a grub menu to choose ubuntu orwin 7,windows 7 boots all on its own.

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'm running Ubuntu within VMWare on a Macbook. I followed these steps [URL]... Recommended) to upgrade form 10.04 to 11.04, which actually upgraded to 10.10 first, and then a graphical upgrade brought me to the 11.04 upgrade, but then i ran into the problem where a grub> prompt appears when i start up the machine... nothing else happens. I found this thread [URL] which seemed similar to my problem, but the suggestions didn't work.
Code:
grub> ls
(hd0) (hd0,5) (hd0,1) (fd0)
grub> boot
error: no loaded kernel.
grub> linux
error: no kernel specified.
that's what I see. any way to resolve this without having to download the CD and start from scratch? It's grub 1.98, if that's important to know.

I have installed BackTrack 5 and I have set GRUB up:
Code:
root (hd1,4)
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
# from /etc/grub.d and settings from /etc/default/grub
# .....
The reason I want the GRUB menu to show up of because I would like to dual-boot BackTrack 5 with Windows 7.

First, I know there are numerous threads on grub errors but I have tried all possible solutions and that's why I'm here. My issue is that I'm not able to boot from the grub prompt as described for installing grub from a LiveCD https://help.ubuntu.com/community/Gr...0from%20LiveCD. I can see grub is installed but is missing the kernal and other files. code...
I ran the boot_info script and the output is attached. From what I can tell it cannot even detect an OS being installed, but I've kept everything up to date and never had any issues. Everything was fine yesterday and now this. Also, I tried the Boot Repair CD and that did not work.

I'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 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 removed Winblows Vista from my laptop and replaced it with Kubuntu 10.10 (I left the recovery partition on there, just in case). When I turn on the computer, the GRUB menu appears, I press enter, then a little flashing underscore appears on the screen in the top left hand corner. After a few seconds, the Kubuntu logo appears and I can log in.But yesterday I replace Kubuntu with Ubuntu 10.10. The Boot process is the same, but the little flashing underscore in the top left hand corner flashes for about 10 seconds longer then Kubuntu 10.10 did, and then a few paragraphs of text appears for a few seconds, then I am logged in automatically.Is this "unusual" boot process anything to worry about, or am I just being a noob.

how to edit the grub listing that appears during computer boot.
My listing shows 3 OS:-
1. Ubuntu 10.04
2. Ubuntu 9.10
3. Windows XP
I have deleted Windows XP, meaning that my system does not contain Windows XP.

Just delete a linux partition and now when i boot a message appears and says error: unknown filesystem grub rescue >
I have search on the net for this problem and i have understand it a little. But my situation is a bit different and because i don't want to format my hard disc i wanna try to fix it. So before a couple months i download ubuntu 9.10 and i installed it a month later. But my computer used to crash all the time and i couldnt use it. So i download the latest ubuntu 10.4 and install it while having windows xp and the old ubuntu 9.10(so i had windows xp, ubuntu 9.10 and ubuntu 10.4 partitions). Now i tried to delete the partition of ubuntu 9.10 from disc utility. so i have the message i wrote above when i boot. I dont wanna delete my windows xp and ubuntu 10.4. what should i do to stop this message from appearing.

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

I have a laptop with Windows 7, and about a week ago I installed Ubuntu 10.10 64-bit via LiLi USB creator. Worked beautifully, but I was having some issues with the brightness controls so I decided to get cute and upgrade to 11.04. So I downloaded the beta2 and used LiLi to make the USB (unsupported for that version of course) which used the same parameters as 10.10. I then tried to do a fresh install over the partition I had set aside for Ubuntu and had 10.10 installed on (~80 GB).
So in the installation itself, something got majorly screwed, and the entire system froze. Next thing I knew, I was rebooting and got the Grub Rescue prompt and no ability to load into either my old Ubuntu 10.10 or my new failed 11.04, or of course my Windows 7 partition either. The partition is obviously there, and as I only have one PC in my house, with no Windows 7 recovery discs, I currently cannot fix the mbr to just get my Windows back. I can of course get this in a couple days, but I'd like to be able to fix this without going to my parents.
[Code]....
Those are my partitions. /dev/sda3 is my Windows Partition, which I want to boot from. Only problem is, I'm not really sure where the computer is looking to find the boot record. I think it's from my fubarred /dev/sda4 partition which means it's basically looking nowhere. So I can't modify it to point to my Windows so I can just get back there.

OpenSUSE is starting to drive me a bit nuts. Actually what I'm trying to do is simply install VMWare server on a recent as possible SUSE and run 2 virtual machines, both the same SUSE. Of course 11.2 32 bit doesn't run VMWare server 2 so it's back to 11.1. The trouble is, 11.1 won't install properly on my PC.
The install process, booted and installed from the 11.1 network install iso image on CD, runs fine. The PC reboots from hard disk and stops at the grub prompt. I've tried the auto-repair option and reinstalled it from scratch a second time always with the same results. It seems the root partition is hosed, and that's where my understanding hits its limits. Can anyone help?
Incidentally should anyone be able to advise on the VMWare conundrum I'd also be interested. Maybe in another thread...

A couple weeks ago I installed Ubuntu Security and Recommended Updates that included an update to Linux Kernel 2.6.31-20. Upon installing these updates I was prompted to restart my computer for the changes to take effect. So I rebooted and encountered a Hyper Transport Sync Flood error each time I tried to boot, preventing me from booting into the OS.The above linked forum thread about the error suggested I manually adjust voltage settings in the BIOS to resolve the issue, so I gave it a try to no avail. Then I decided I would just reset my BIOS settings to the defaults (seeing as I hadn't edited that many settings to begin with). After doing so, I tried booting only to encounter a black screen with "GRUB _" printed on it.
I have encountered this issue before when I initially installed Ubuntu 9.10 on my system, but I'm not sure whether this occurrence is strictly BIOS setting related or if something effected my bootloader. (On a side note, resetting my BIOS settings to defaults seemed to, at least for now, eliminate the Hyper Transport Sync Flood error I was getting...and instead leave me with another problem.)I used this script created by meierfra. to provide info on my current boot setup, the results of which are displayed below.

I installed 10.04 clean on the PC.Not other operating system.It booted to Ubuntu fine after the install and all appeared to be working fine.Used the upgrade manager to install the upgrades to the basic system.I had not yet loaded in any non-ubuntu or medibuntu repositories so this was the first, basic upgrade.After the upgrade,I can no longer boot to Ubuntu but boot to a grub prompt instead.I presume this is a recover prompt. How do I "recover" and continue booting to Ubuntu?

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.

I 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:
GRUB loading
error: no such disk
grub rescue>
>
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)

I upgraded my dell inspiron 6000 from ubuntu 10.04 to 10.10 then rebooted and now I am stuck at the grub prompt. I am able to boot from a flash drive and have run the boot script. This laptop did not have a dual boot system on it but it did have windows on it at one time, converted to ubuntu.
