Debian Installation :: Grub Prompt After Install On IMac
Jun 3, 2015
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:
[ 3.538535] i8042: No controller found
Loading, please wait...
Fsck from util-linux 2.25.2

Debian GNU/Linux 8 iMac tty1/I was able to get my hands on a USB keyboard which works. Obviously I can't boot into Mac now because grub has taken over.

I have installed Debian a few times now (and other distro's), so I'm fairly used to installing linux. I'm not used to installing it on Apple hardware (back in 2009 on my laptop I had some issues that were solved rather quickly, but that's about it). Now I'm installing Debian Squeeze on a new (well, bought today, but it is the previous model: iMac 11,2) desktop iMac.
Installing goes well (resizing partition, rEFIt, booting Debian 6.0.1a netinstall CD, installing packages etc.) I followed a tutorial [URL] to install grub explicitly with force after installing and running gptsync. Everything went according to the tutorial and I rebooted to be welcomed by rEFIt and then grub: perfect!
BUT when I chose Debian in the grub-selection list, I only see a few lines of starting the kernel, and then my screen goes all black. A few seconds later I hear a sound, and iirc it's the sound of gdm prompting to select a user. I cannot switch to a TTY and I have to use the power-button to shut the system down.

- i did the windows cd fixmbr trick, not worked
- reinstalled debian with fixmbr the first step and nothing

I initially installed Debian 8 onto my iMac G5 (with KDE), and it would boot to a black screen. I then tried again, and reformatted+reinstalled with only "Standard system utilities", "Print server", and "SSH server".The boot hangs before I get to a log-in prompt. Please see the attached log files I pulled off by booting from the rescue CD option. (I got an error when attaching the log files, so I used tinyupload to upload the files.URL....
Here's some of "syslog"

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

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.

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. After I completed the install I get GRUB prompt and I cannot type anything.

I decided to upgrade my FC installation to the latest version - FC itself offered the upgrade when I turned the machine on, so it appeared that it was nicely packaged to make the upgrade easy.After a long download of packages, the machine rebooted and then started taking me through configuration options (timezone, disks to use for the installation etc) but then it crashed trying to write to disk and now leaves me at a grub prompt whenever I boot.Is there any way to "get at" the installation files and get back into trying to install or do I now need to download an ISO and burn a DVD and start all over again?

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 have just installed Debian 7.8.0 powerpc on my imac G3 (400Mhz, 256Mb Ram). I had repartitioned the drive with the view of having a dual boot machine, had OS9 installed on partition 1, linux installed on partition 2 and a ext4 data partition and a 1Gb swap partition. After I installed OS9, I ran Debian Installation CD and was successfully installed. Rebooted, got through the on screen text past file system check, then screen went blank. I searched Google and forund that if I ran ctrl+alt+f1 and logged in, then ran lspci, I could get the ID of the graphics. So I did, and:

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)

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.

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 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.

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.

I have downloaded the latest version of Debian for PPC to run on my iMac G3 600MHz 1GB ram. The problem is, is when it is partitioning the HD the computer just shuts down and restarts from the beginning. I don't understand this. I chose it to erase and use the entire disk. The HD is 80GB. I really want to install this OS!

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.

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?

I have the following problem. I tried to make a persistent USB Backtrack 4 r2. I followed the steps according to the instructions and did not noticed any errors.
fdisk /dev/sdb
Command (m for help): d
Partition number (1-4): 1
Command (m for help): n
Command action
[Code]...
I can boot from USB because when i use Unetbootin everything works fine. Although it'snot persistent in that situation. I seachered the web but i can't find the solution. I have run a script which i ran into on Sourceforge.net. The results are in the attachement. But unfortunately i am real Newbie on linux so..
