Ubuntu Installation :: After Update Boot To Grub Command Line
Sep 29, 2010
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.
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'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.
I upgraded from Meerkat to Narwhal. After all the files have been downloaded and installed it rebooted. Once it rebooted it went straight to the GRUB command line. After couple of hours of research, I ended up at [URL]
My root was at (hd0,1). So therefore I put this in at the GRUB prompt.
set root=(hd0,1) linux /vmlinuz root=/dev/sda1 ro initrd /initrd.img boot
I did what it said and it got me into Ubuntu. Nice! It asked me to: After successfully booting into the system the user should run sudo update-grub I did. Next it asked me to review (/boot/grub/grub.cfg). That's where it is hairy, my file has multiple root settings and with msdos settings. That doesn't seem normal.
i have successfuly installed ubuntu karmic inside my windows 7. After an update, i restarted it. but it didnt boot ubuntu. instead it shows grub's command line. what should i do? all of my java projects/programs is in there.
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?
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 made a live USB memory stick / pendrive with Ubuntu netbook remix 10.04 using my desktop computer. I want to install / update my netbook that has no network function yet. I booted the desktop with the pendrive & ran update manager. I want to update the kernel so I will have the driver that will operate my netbook ethernet.Acer AOD260 has Ethernet Controller: AR8151 v1.1 Fast Ethernet, Atheros Communications & Network Controller: Broadcom 4727 (rev 01)and will not work from the current release of 10.04 (too new) but there are supposed to be drivers in the newer kernels.
Running Update Manager I get a box labeled "Debconf on ubuntu" & says "Configuring grub-pc". There is an entry box that says "linux command line:" & is empty. When I press the help button I get the message "The following Linux command line was extracted from /etc/default/grub of the 'kopt' parameter in GRUB Legacy's menu.lst. Please verify that is correct, and modify it if necessary.The installer is hanging, Preconfiguring packages ..., probably waiting for a response, but I have no idea what to do.
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?
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?
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...
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...
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 can only boot fedora and red hat on my pc, I like fedora but Im having acpi problems and need to upgrade BIOS, which should be done from windows I hear. So I deleted fedora partition and plan on re-installing after all this.I've used http://www.ultimatebootcd.com/Iboot loads up but than complains of not finding something with acpiI tried knoppix but i think i was suppose to extract before I burned Ill try again if suggestedany ideas on how to get windows up i've tried many windows disc to no success
I am dual booting Windows Vista and Ubuntu 10.04 with WUBI. (Windows works fine). When I updated Ubuntu from the update manager, it just gives me this error code from a JPG attachment I just added with this post. It keeps on saying that every time ubuntu boots up.Is there a Fix? I cant boot up to ubuntu at all...
I have been phenomenally unlucky with Ubuntu as seen my my post history and decided to dual boot.
I set it all up with a clean install, when I tried to load Windows from Grub the computer restarted. After much headache I managed to set it up correctly (when it wouldn't load from Grub I booted from the Windows CD and clicked on "Repair computer" and it finally worked).
Now I am having the same problem as before--I think my installed all the updates from Update Manager and it included a grub one. Now I can't load Windows from the grub menu: It goes to the Starting Windows screen and then reboots my computer. If I do it again it gives me an error message and an option to perform "Startup repair". When I try to do Startup Repair, the computer reboots after a few loading screens.
So I tried what worked before and put in my Windows 7 CD, and clicked on Repair Computer. BUT NOW it gives me an error message somewhere along the lines of system restore is not compatible with my installation of Windows, and to insert a compatible recovery CD. This is the ONLY Windows CD I have (legitimate copy).
Over the course of this migration experiment I have installed and reinstalled both operating systems 7-10 times total. I'd rather not do it again. My poor laptop is probably wondering what the heck.
I can't stick with Ubuntu alone because my wireless doesn't work with it, my grad school files are not completely compatible with open source software, and I can't play the games I'd like to. So I must have the option to at least dual boot into Windows.
When selecting Windows it restarts the computer entirely to the Compaq screen, not just to the Grub menu, if that matters.
I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.
I recently installed Ubuntu (Karmic Koala) on a Dell Inspiron 1525 which already had Vista installed on it. The installation went just fine and I could boot into either Ubuntu or Vista using the Grub bootloader options. After updating grub through the update manager however, I can no longer boot into Vista and get an error message that says: "Windows cannot start. A recent upgrade or hardware change may have caused this".
And below that: File: \boot\bcd Status: 0xc000000e info: An error occurred while attempting to read the boot configuration data"
When I run sudo fdisk -l, I get the following: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000080

Partition table entries are not in disk order. I have the Vista recovery disk but was wondering whether using it to repair the Vista bootloader might mess up Grub.
With a bit of help from this forum I managed to install 10.04. The solution was to add i915.modeset=1 to the options when booting up from CD.Now I need to do the same in order to boot up from HD. I've opened /etc/default/grub and changed the relevant line to include the above option. But I need to run "update-grub" and it comes back with an error to the effect that it 'can't find a device for / (is /dev mounted?)Also, the boot menu only has ubuntu - no sign of windows in my intended dual-boot. What can I do?
I just updated my server from Ubuntu 8.04 to 10.04 and now it cannot go past grub, at boot time, it would "give up waiting for root device", asking me to check whether I gave the right "root=..." or if I should increase the "rootdelay=..." in the command line argument and end up with the initramfs.
The machine is a Dell Poweredge 2900 with a HW RAID controller (I hope that should not matter, but just in case...). I tried to follow the instructions there to make sure grub is setup correctly, but without any luck.
Below is the output from the bootinfoscript (while running on the LiveCD). Anybody has any idea what can be the problem or what I could do to debug this ? I am running out of ideas.
