Ubuntu Installation :: Wubi Doesn't Boot - Loads Grub Command Line?
Jan 1, 2010
My Wubi installation of Ubuntu (version 9.10, I think) that I recently installed was working fine at one point, but now it isn['t. I select Ubuntu instead of Windows from the Windows boot loader, but instead of getting the usual menu of different linux versions (I think 2, as I updated it at same point), and Windows, I get the GRUB command prompt instead.I've looked at th2e Wubi Guide (https://wiki.ubuntu.com/WubiGuide), and I've followed the instructions for "How can I access my Wubi install and repair my install if it won't boot?", but that reveals no problems.For the record, I'm fairly new to linux and ubuntu, but I'm good with computers generally. The main operating system on my computer is Windows Vista, but I'm currently typing this from a Live CD of Ubuntu 9.10. The virtual disk (root.disk), is currently mounted as vdisk, as indicated in the Wubi Guide.
Ideally I would like to get Ubuntu to load as it used to (with a menu). However, if there is a way to boot from the GRUB command line that would be good too. I'm not at all familiar with GRUB, and the commands I've tried (boot and linux, I think), get errors saying no kernel specified, or loaded, or something like that.

I recently updated, and now when I boot it only goes as far as grub command line. There is no grub menu. The computer is a Dell Inspiron 8600 laptop with only Ubuntu installed -- no dual boot, no weird partition schemes. Originally installed Ubuntu 09.04 on this computer, upgraded a couple times and it currently has (had) 10.04.1 LTS running. The update should have upgraded from kernel 2.6.32-23 to 2.6.32-24. I can boot with a live CD and mount the hard drive. The drive seems fine, so it appears to be simply a grub config issue. I have to boot with live cd to get online to check for potential solutions. So I'm taking some notes on how to use grub.

I've recently had trouble reinstalling my Ubuntu system as I was getting various unusual errors as described in my old thread here. I thought it was probably something to do with my RAID-0 array which was pre-installed on my laptop from purchase being corrupted or something like that (if it's possible). I decided to simplify things for myself (not understanding RAID arrays much) so I just removed the RAID array and installed Windows and Ubuntu on the now separate hard disks. It worked fine.
I noticed quite a significant performance drop, however, with even Ubuntu boots taking longer than 30 seconds despite my laptop being both high-spec and only a few months old. Windows, as you can imagine, was dreadfully slow. I wasn't entirely convinced that this was entirely due to the loss of the RAID array - as even low-spec laptops with presumably no RAID arrays are supposed to boot Ubuntu in under 30 seconds apparently - but I read that RAID-0 arra

I'd like to say I'm very impressed with Fedora 11. I'm a long time Linux user and I've tried many distros. But, I usually keep only the best on my laptop. For a long time that was Ubuntu but, I think Fedora 11 has made some key improvements over Ubuntu and I'm eager to switch. The problem is: I haven't been able to run Fedora as anything other than on the Live CD. Everything works perfectly and it installs but, when I reboot, Grub begins. Instead of booting, however, Grub drops into its minimal shell and gives me a command line.
I've tried installing it a number of ways now and have read much about the problems with Ext4 on Grub and took special care to see that Grub has its own, separate, /boot ext3 partition. Even then, no luck. My hardware should work fine. I've got an HP DV-5 with 4GB RAM, AMD Turion 64-bit dual-core @ 2 Ghz, and an IDE 250GB hard drive. I'm working with the 64-bit Fedora 11 Live disc with KDE as the Gui.

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..

I performed a clean install of Fedora 15 from DVD and it goes fine until the end when the install program says to reboot the computer. Once I do that, the computer hangs before Grub loads, i.e. just after all of the BIOS messages, so there isn't any error message to indicate what is wrong. I had no issues with Fedora 14.

Out of curiosity and stupidity, I configured 2 extended partitions to LVM in gparted. Now, I can't boot into X window, and there's only GRUB command line during boot.

Running Ubuntu 10.10. My desktop environment is screwed up and won't let me use the keyboard or mouse at the login screen. How can force a command prompt during boot?
Here's a method:

It used to be with (old) grub you could hit a function key and add a runlevel option to boot a console, but I don't know how to do this here, wanting not to edit the grub config file, as seems the only apparent option: I'm trying to boot into SimplyMepis where there is no rescue menu option, so need the prompt?

Installed Ubuntu 10.04 a week ago or so (using wubi.)Tried to upgrade to 10.10 from within Ubuntu using the update manager.Now the PC will only boot to grub rescue.When booting, this is what i get:error: no such device: cd200414-0606-4d7d-8c08-004e9b5dc92d.grub rescue>Three commands work: ls, set and insmod.The ls command only yields: (hd0)(no partitions like (hd0,1), (hd0,5), etc.)

I just installed Windows 7 and it erased my Grub bootloader. I followed this tutorial: URL...And now when my computer starts up it goes to the Grub prompt: Code: grub>I guess I did not do the right partition but I'm having a lot of trouble getting it back to how it was where my computer at least loaded the Windows 7 loader.

I do computer forensics here in Afghanistan and I am trying to keep a clean image of a dual bootable hard drive. Here is what I try to do...
1. Boot into UbuntuLiveCD
2. I run "sudo dd if=/dev/zero of=/dev/sda conv=sync,notrunc bs=64K" to wipe the drive with all zeros.
3. I then install Windows by creating a new partician about 50GB.
4. I then install Linux by creating a partician in ext4 mounting it at '/' in addition I create a swap partician.
5. Next configure everything just the way I want it. I install all the drivers and software I need for my windows partician and build out the remaining part of the disc as a "data drive."
6. Then I use "dd" again to try to image my "clean slate" of a system. Remember I am dual booting. I dd the /dev/sda and gzip it.
7. When I go to restore it, I boot from the live CD again and unzip ig and "dd" it back onto /dev/sda.
8. I run fdisk -l and I get:/dev/sda1 * 1 6375 5120000000 7 HPFS/NTFS/dev/sda2 6376 11724 42965842+ 83 Linux/dev/sda3 11725 12453 ...... 82 Linux swap / Solaris.This means to me that it can "understand the file system"
9. But then when I take out the Live boot CD and try to get my "clean slate" machine back, the system goes into Grub Rescue mode with a grub command line "grub rescue>"
10. I tried using the tutorial on Grub2, but...
a. It would not understand the command "linux"
b. When I try to do insmod, it says it doesn't recognize the file system.

I wanted to install Debian 8.0 on my second hdd in my UEFI machine, but when I choose UEFI boot from USB, GRUB command line appears, and I cannot boot up the setup. I used Rufus to create the bootable USB stick, using the amd64 kde CD image. I tried several images and I deleted the Linux and Efi partitions from previous installation of Ubuntu . Also I deleted GRUB from the Windows 7 Efi partition.
In the UEFI setup fast boot and secure boot are disabled, and I don't seem to have the option to boot in legacy mode, if I choose the simple USB boot option (without "UEFI" in front) I get "please insert correct boot media, and press any key or reboot". I couldn't manually boot from GRUB command line, because it is showing that all the drives are empty, and if I type "boot" I get "please load the kernel first".

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

When I boot my pc it used to take me to a prompt which asked which OS I would like to boot. Today randomly, some grub rescue menu came up. I read online that that meant I had to fix my grub menu, which I did. Now a regular grub menu pops and and I have no idea what to do with it. Whats a grub menu? How can I just get back to my regular boot screen? I run dual boot xp and ubuntu, is grub a program of xp or ubuntu? I have no idea what this grub menu is and whats going on with my pc!

I just installed a fresh install of 9.10 on my amd64. when it starts it locks up right away. i know that this has to do with my nvidia card. i've had to do this in the past. but since it locks up i have no way to get into the command line. ctl-alt-F1 does not work. is there a way to just have it boot right to the command line without loading up gdm?

What is the simplest way to boot to command line rather than gdm ?
I've seen post to change
# The default runlevel.
id:2:initdefault:
to
id:3:initdefault:
and
update-rc.d -f gdm remove
update-rc.d -f kdm remove
update-rc.d -f xdm remove

Ive installed Ubuntu 10.10 from a SD card (yes my laptop supports booting from SD) and it works fine except the grub does not load. Although I know there are many threads about this Im not sure which one to use because my problem is quite strange.
Im not pretending I understand how grub works but I find it strange:
When I boot from Hard Drive, it boots into Windows without loading grub (I installed ubuntu to an empty partition along the windows on the same drive), however, when I force booting from the SD card, I get the grub window with all the options as expected - ubuntu, mem check, windows 7. Now Im not sure if its grub loading from this SD card (containing ubuntu) or the card somehow runs the grub that is on the hard drive.
My guess is that the partition containg windows (sda0) is flagged as boot and thus the system doesnt even look after grub when booting, however, when theres the SD card it somehow forces booting the ubuntu partition (sda6).
Any idea what I should do? I can boot into Ubuntu, I can access grub etc. I just cant make it load without having the SD card in my PC

Code:
grub-install -v
grub-install (GNU GRUB 0.97)
I loaded GRUB, and now when I reboot it goes straight into the 'grub>' command line. Initially GRUB had the root as (hd0,2), whereas the boot is on (hd0,1)...(hd0,2) is my '/home' partition, and (hd0,1) is my '/' partition... So on a bootup I ran...
Code:
root (hd0,1)
setup (hd0)
Now when I boot I still get the 'grub>' command line, but now the root is correct.
From 'grub>' I can type...
Code:
grub> configfile /boot/grub/menu.lst
GRUB will then show the menu, and I can click the listings to load them. All's fine, but why doesn't GRUB just load the menu.lst without my prompting? How can I automate this process of typing 'configfile /boot/grub/menu.lst' each time I boot?

I loaded Kubuntu 9.1 and got a mess in the Grub 2 Boot Menu, which I can't correct.
I get extra choices in the Boot menu, and the first few, which are supposedly for Kubuntu Karmic Koala all put me in a shell, which ends in a black screen, then shows up a shell once I hit "enter". Then I just have a "intramfs" (?) prompt.
So I went into Grub2 to change it, and it refuses to do it. All I get is a screen full of error messages every time I try, with no change. Apparently it is looking to access drive sdb8, which is non-existent. I DO have a drive sda8, though.
So with all the wonderfulness of the indirect system to change Grub 2 how am I supposed to set it right? The old Grub worked fine, and just took simple changes to the menu.lst file.
Can't somebody write a program that lets Grub 2 be changed from within the program, rather than all this running around trying to find what file to change, and how to get the change to work?
Just to be clear, here are the errors as they show up when grub-update is flailing around:
"error: cannot open '/dev/sdb' while attempting to get disk size
error: cannot open '/dev/sdb' while attempting to get disk size
Generating grub.cfg
error: cannot open '/dev/sdb' while attempting to get disk size

Ubuntu 10.10 doesn't boot at all. The liveCD only boots once every like 30 attempts, installing from liveCD froze, but the Alternate CD worked and installed ubuntu. Now when I try to boot into it using GRUB, it freezes at the beginning of the boot process.With normal boot it freezes at line: Starting AppArmor profiles Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox.With recovery mode it freezes even before showing me anything
A little kinda like the liveCD, if I try like 30 times, it might manage to boot once in normal mode.That line keeps on repeating, the the xxx.xxx integer changes each time, and this goes on forever.I tried removing my floppy drive, but it didn't help.I tried to boot with fd0=noprobeThe one time it booted, when I restarted, it froze while trying to restart.

How do you change the order of the list? I have Xubuntu 9.10 installed on a 5 gig partition. I only use it for Skype as the mic does not work in 10.04 at the moment for me.Anyway, I would like 10.04 to default to the top of the list. How do I change the order when grub loads.

i just installed the Debian on my old laptop. The install went fine but after that, the GRUB menu loads and freezes. I simply can't do anything. I checked menu.lst and the timeout is set to 5 but still nothing happens. It won't load. I then tried to load with the "super GRUB disk"but the same problem - as soon as it loads from the CD, it freezes and I can't do anything. Before I had Xubuntu on the same laptop but there was no Grub menu. It simply loaded. There's only 1 OS on the laptop /currently Debian/ - no windows, no other Linux.
