Ubuntu Installation :: Unable To Boot From Grub Prompt - CD On Lucid / Sort It?
Sep 1, 2011
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.
upgrading my Karmic 9.10 to Lucid 10.4 I can't boot anymore to Linux only to Windows.My installation is a WUBI installation and I installed it on the only harddisk I have in the folder c:ubuntuNow when I boot I get a grub prompt and when I do LS I see hd0,msdos01 as partition.Now's I've tried to manual boot it by using the following commands from the ubuntu manual
set root=(loop0) linux /vmlinuz root=/dev/sda1 loop=/ubuntu/disks/root.disk ro after this command I get an error
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'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 had 250gb hard disk with dual boot, xp and ubuntu 10.10.Yesterday, i tried to upgarde my ubuntu 10 to 11 from a live cd....b4 doing so, i used a win software EasyBCD to fix the mbr but it didn't work properly..and i ignored it(my biggest mistake)and deleted the ubuntu partion from the windows device manager. It just displays "Booting from Live CD" for few minutes and again displyas the same above error.What should i do now?Its ok if i m not able to recover my data back...i hv sycnd my docs on the internet.
I had Ubuntu installed, i installed Debian and there was no dual boot. So i formated all the hard disk to install only Debian. It installed but at boot i get error: no such device and the grub rescue> prompt. i googled for a solution and nothing worked:
- i tryed reinstalling grub, not worked - i did the windows cd fixmbr trick, not worked - reinstalled debian with fixmbr the first step and nothing - tryed deleting with dd the mbr, not worked - reinstalled grub from debian rescue, not worked
what should i do? i can't access my computer? please tell me how should i fix it? the google guys will kill me because i put their servers on fire
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've got a machine that I'd got 9.10 on, that I've now upgraded to Lucid Lynx - and I'm having the same problem with dual boot (or lack thereof) that I was having previously.
Rough scenario is:
(Original Vista machine had)
C: Windows Vista OS + Windows software, etc.: 500GB - single NTFS partition - SATA drive
D: General dumping ground for data. 500GB SATA drive. Was single NTFS partition, now shrunk to install Ubuntu.
So is now: - NTFS partition (containing general rubbish) - Ubuntu / partition - Ubuntu swap partition
... and then 3 x 1TB SATA drives making up an (Intel ICH9R) FakeRaid RAID5 array - that Windows can happily 'see' and use, but I don't care about Ubuntu having access to it or even seeing it.
Lucid Lynx is installed to /dev/sde6 (IIRC) - but when I boot the machine just boots straight into Vista.
I've done what I can to try and get GRUB correctly installed - to the point that right now I probably have it splattered just about anywhere and everywhere.
So - now - the machine boots and simply presents me with "GRUB Hard Disk Error" and stops...
I can fix this by running the Vista repair, with a fixmbr etc. and putting the MBR back to 'normal' on the first boot disk (/dev/sdd in this case). The machine then just boots straight into Vista.
...or I can boot into Ubuntu (or Vista) by booting off a Super Grub Disk (CD) and selecting "Boot Linux" (or whatever it is) - and it correctly boots Lucid Lynx from /dev/sde6
Ideally I want a proper GRUB dual boot menu - but I just seem to be getting into more and more of a mess!
I use an IBM Thinkpad T30 with an ATI Radeon Mobility 7500 graphics card as my work machine, mostly at a desk, using a docking station to link it into a monitor. I upgraded to Lucid last weekend. When using the integral screen on the laptop the graphics have been fine, but when using a monitor I initially got some very poor contrast, brightness and gamma output, described in this bug.
According to the advice in that bug report, I upgraded the kernel, with Kernelcheck automatically updating me to 2.6.35-candela. Now, rather than poor graphics with the monitor it just hangs on the splash screen, displaying the words Ubuntu with the dots underneath.
Reading around, when similar problems have been seen in previous versions of Ubuntu it has been a graphics issue, which fits. One piece of advice I've seen quite commonly is to remove the "quiet splash" from grub, which I've tried but doesn't work. I am tempted to try and work through the different grub commands these guys used to tackle a similar problem with the live CD:
http://ubuntuforums.org/showthread.php?t=1472054
But am a bit reticent as I don't know what they all do.
As an aside, the 2.6.35-candela kernel brings up a bunch of errors on boot, described at the link below, but reading that thread they don't look like they would cause my problem:
I run Lucid on ext3. I really miss not being able to reach Lucid from my dual boot Vista.I have installed the latest fsdriver. I have also tried this:[URL].. which does not work. (Is it because fsdriver is still in the system?) I also tried these methods but to no avail.[URL]. The problem seems to be related to fsdriver not being able to handle ext3 with Inode size = 256. Going back to ext2 for only the home partition seems complicated?
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?
The problem is I've set up a dual boot with Xp and Ubuntu 10.04. Ubuntu was working fine till 2 days back but now when I select Ubuntu from the grub screen i get a whole lot of numbers next which it'll say Usb drive or sd card reader etc.. these go by quickly and then the comp stops running. If i press enter on the keyboard I get Initramfs and then i can type but nothing happens even if I type reboot. if I press cntrl+alt+F2 then i get a blank screen with flashing cursor. Same with recovery mode. Windows boots fine. The grub2 screen comes fine. The last thing i did before this happened is reconfigure the grub2 screen, but it seems to be fine (i had added a background img and reordered the boot options) I did not edit grub.cfg. I would prefer not to reinstall it as iv done it a half a dozen times already in the last few weeks..
through a series of mistakes i have managed to take a working system and make it unable to boot. my two objectives right now are to back up my data, and to make my system bootable. here's how i got here. i used the Upgrade Manager to upgrade to 10.04 thinking it would solve a problem i was having with my previous installation. when that had completed i found I was unable to boot into 10.04. The system would hang after echoing the message "checking battery state." I attempted to rebuild my grub file, thinking this would solve the 'battery state' problem. this was a mistake. I ended up deleting it, and now there's no menu.lst file in its place.
currently when i boot up normally (i.e., with no Live CD) I automatically go into the rescue mode. so far i haven't managed to enter a command that rescue mode recognizes. alternatively, i can boot from the installation CD for Ubuntu 10.04. per this page: [URL] I take these steps:
1. boot from the installation CD. 2. go into terminal 3. type these commands:
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.

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.
I had 9.10 installed and I did an upgrade to 10.04. However I cannot see anymore my Windows Vista partition with grub.. I have a Toshiba laptop Satellite p305.This is my boot script output:

I upgraded from grub to grub2 recently, and during an update of my system, it ran the update-grub command which prompted a window asking me where to install Grub. Since I didn't know what partition to install it to and the help suggested to install it to all if I was unsure what partition to install it to - I accidentally installed Grub to my Windows partitions (both the regular and the recovery console).
So now, I can't boot into Windows - the computer just hangs after Grub with a blinking cursor and I have to perform a hard reset. Is there any way for me to restore the boot record for the windows partition without having to reinstall windows from the ground up?! I can't use Linux for my webbanking and other important tasks, so (unfortunately) I need Windows back desperately!
I have accidentally started the recovery OS of my netbook, and messed-up grub. I can start the Netbook from a live CD, but I do not manage to restore grub to anything useful. Below the outcome of the Boot Info Script I have found in the forum:
Code:

I updated a RHEL 4 system today using up2date and when the system rebooted it just said "GRUB" on the screen for a few seconds and then restarted (and did this over and over and over).
I booted from a rescue CD and was going to reinstall grub.
Here's the kicker: this machine has two hard drives configured with software RAID 1, and I don't want to screw up the mirroring by tinkering with grub.
/etc/fstab shows that /boot is at /dev/md0 but "/sbin/grub-install /dev/md0" doesn't work ("/dev/md0 does not have any corresponding BIOS drive").
I have a bad feeling that if I do "/sbin/grub-install /dev/hda1" that I'm going to screw up my mirroring.
I have win 7 and F13 installed on my computer but I am having trouble setting up dual boot so I can choose to boot F13 or win 7. I have tried to set up grub, how to install grub and set up a dual boot so I can use F13.
I recently performed a reinstall of ubuntu after mucking up my partitions, and I am running it dual booted with windows 7.
I recently performed a grub-pc update, but I didn't know what it was asking me to do during the process itself of updating the process.
It asked me at one point where to install grub, and I selected all my partitions because it suggested that if I didn't know. I think that may have damaged my windows section, which was also selection.
I've attached the output for:
Code:

1) Weird upgrade error in apt-get 2) Unable to boot windows 7 3) Unable to activate proprietary drivers 4) Perpetually being reminded to restart
yestoday,after I upgrade,unable to boot windows xp. if I use grub ,windows xp can boot up.but now I want to use grub2, boot info script's results.txt is at below.

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. So I booted from CD again and opened ubantu from disk. ran the boot_info_script as mentioned on other posts here and here is the results

I recently tried to clone a RHEL 4 system and migrate it to some different hardware (IBM Blade to an IBM x3650M2 rack mount). I'm getting an error when it tries to boot up. It gets past the grub part, but then errors out quickly with this error code...
I've done this before, but the other system I migrated didn't have a separate "/" and "/boot" partition. I think this may be why it's having an issue. It seems like "/boot" is actually /dev/sda1 and "/" is /dev/sda2 (from booting up RHEL rescue disk). I've tried changing fstab and grub.conf, but I think I may be missing something.
I have a serious problem! I downloaded and burnt Ubuntu 10.04 and then chose it as start up volume in Snow Leopard's start up disk preference dialogue and although Ubuntu runs successfully from the cd (I'm typing from it now) I can no longer boot into OS X at all.
I have tried all of the different short cuts at boot up to no avail, even trying 2 keyboards. It insists on looking for the Ubuntu disk and if it is not in the drive comes up with an error message stating that a system disk cannot be found.
Is there any kind of tool on Ubuntu that will let me change the start up disc/interact with the Mac's efi settings? I previously had refit installed but this disappeared just before I booted the cd, is it worth using the live cd?
I tried booting from a Tiger dvd but it wouldn't let me do so, it just returned me to the ominous "System disk not found" message.
Does anyone have any kind of idea? Perhaps some kind of shell script that will reinstall refit? I'm guessing that any kind of dvd designed for PC will prob boot, any kind of OS X recovery disk compatible with MBR available?
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...
