Debian Installation :: 8.0 - Setup Boots GRUB Command Line
May 2, 2015
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".

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 used the Wubi installer to install the latest version (available from the website) on my second physical HDD. I rebooted my machine and used the Windows 7 bootloader to launch Ubuntu and it launched a GUI install. I wasn't sure how long it was going to take, so I left for about a half hour and when I returned I was back to my Windows 7 logon screen. Naturally, I assumed the install was a success and I rebooted my machine. When I boot again I get the Windows bootloader and I see my options for Windows 7 (which works properly) or Ubuntu. However, if I select Ubuntu I am brought to a command-line and there is an output at the top of the screen stating "Grub bootloader." At this point do I need to type anything to launch the GUI (I'm assuming Gnome) from this? How should I proceed from this point, reinstall?

After installing the 10.10 Maverick Meerkat, I decided to have a new partition and install Windows 7 on it for development purposes. So this is the method I worked with:
Partitioned the hard disk with gparted
Formatted the drive in NTFS
Installed Windows
Booted into Ubuntu 10.10 Live CD and re-installed grub on the MBR Now after restarting the system a grub command line boots up. I was able to boot into ubuntu with the following commands:
Code:
find /vmlinuz
kernel /vmlinuz root=/dev/hda1 (or its equivalent)
initrd /initrd
boot
Is there any way how to load up the grub GUI with the options to boot up Ubuntu or Windows 7 respectively?

The ability to manually boot using the Grub command-line constitutes a big security risk in Linux, IMO.Any OS can be booted in this manner from a PXE-LAN, USB, or CD/DVD drive, circumventing BIOS-imposed boot restrictions. (Once a foreign OS is booted, of course, it can be used to access any part of an unencrypted hard drive.) Placing passwords or locking menu items (in the Grub configuration files) does not prevent a user from booting manually using commands entered at the grub command-line.
As it stands now, when presented with the Grub menu (or after bringing up a hidden Grub menu with the "ESC" key), a user only needs to hit "c" to enter the Grub command-line mode to facilitate any type of bootup whatsoever. (They can then enter manually the Grub commands to boot an OS on any device.) This is extremely insecure and allows any passerby to boot the computer with a few keystrokes and a bootable USB drive. How do I configure Grub so that it will require a password in order to enter the command-line mode (and thereby restrict boot options to the menu, which can then be password protected/locked) ?

I clicked on the upgrade to LTS 10.04 option on my Asus 901 EEE PC and after completion it will only boot straight to command line...I would like to get back to the UNR Gui.

I did a dist-upgrade this morning, and now every time I boot, it only goes to the command line login prompt.
Attempting to stop and restart gdm does nothing besides make the screen shake for a second, and I've installed all available video drivers from Available Drivers, and the ones from nvidia's website.
I am, however, able to boot into recovery mode and then select failsafe graphics mode, and get into the desktop.
Any ideas how I can get my normal boot to work?

I was having so much trouble with ubuntu 8.04 that I deleted off my computer and did a fresh install of 9.10. I downloaded the 64 bit iso from the internet, burned it to a disc and installed it. When it asked if it should be the server version I thought I said no. Now when I boot it only boots to the server version and all I get is command line. Can I get out of this and get my regular ubuntu screen back or did I install the wrong version?

A failed upgrade, from disk images, of Fedora 10 to 11 resulted in no GRUB bootloader main menu appearing on bootup (no WIN, no LINUX choices from which to boot). I am booted directly into the GRUB command shell...so, no WIN, no LINUX, nothing. And my understanding of GRUB shell commands is very low.I have 2 hard disks, WIN on the first, LINUX on the second. I believe GRUB Bootloader is on the first disk.Sadly, I have no external install media.An old grub.conf hardcopy indicates that root =/dev/sdb2, root (hd1,0), kernel /vmlinuz....olderversion...(relative to /boot),initrd /initrd...olderversion... (relative to boot). and WINDOWS on (hd0,1), with chainloader +1
I need to somehow get past this grub shell, and re-install/re-instate the grub bootloader, so it can boot normally.What grub command(s) must I use? I've played around with the commands, but with no success.I worry that if I can't resolve this, the whole machine may be useless.

I installed Ubuntu 10.04 via CD and am currently dual booting it with Windows 7. I have a Sony Vaio VPCEA laptop if that matters. After installing Ubuntu, I'm not seeing the GUI when it boots. It will only go to the command line. Worst of all, it's not responding to the "startx" command. That was working last night... not now. Anyway, all I want is the see the GUI on startup. I want to see the splash screen, then the GUI. Very simple. How to do this?

Occasionally Lucid boots to what I can only describe as a command line desktop-ie the whole screen is like a terminal, theres no GUI, have to restart by hitting the power button. Is there anyway I can stop it, or start the GUI from there?

I decided to dual boot install Ubuntu with my Windows 7. After a lot of hair pulling, i finally managed to boot the live cd environment with "nomodeset". From there i installed ubuntu. When it finished installing, i booted to the new ubuntu install only to be presented with a command line login. If i change the boot line from "quiet splash" to "nomodeset", i can coax ubuntu to boot in low graphics mode. However this is not a permanent fix, and doing so causes a 2 inch offest of the screen on the right hand side. Only the have the missing 2 inches appear on the left side. If from the "Ubuntu is running in low graphics mode" message, i select "console login", and type "startx" i just comes out with "X Server Fatal error- No Screens found". I also tried:
Code:
But it still didn't help. I'm running out if ideas here, can anyone point me in the right direction?
This is a cd that i got free from Canonical themselves. It's Ubuntu 10.04 LTS, and I have Intel Integrated Graphics.

I successfully installed 10.10 dual booting with Win 7.Today I booted into Win7 and Windows insisted on running checkdisk. After about 10 minutes Windows booted. I then rebooted into Ubuntu. Unfortunately Ubuntu only boots into the command line now. Being very new to Linux I don't have any idea how to fix this.

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 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 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'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.

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

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 am pretty new to C.L.I/text editing work. So maybe its a bit old-fashioned but I am interested in learning how to send email via the command line. I am running 10.04 32 bit
Situation: I have followed the explicit and step-by-step actions at http://klenwell.com/is/UbuntuCommandLineGmail
Question: Upon completion, when trying to send a test email to myself via gmail (from CLI) I get the following error: "msmtp: no recipients found". In CLI below it asks me to explicitly pick a mailx to download. I think I already have mailx as when I type mailx I get "no mail for primary".
Here is my work
Code:
:~$ sudo apt-get install msmtp mailx
[sudo] password for:
Reading package lists... Done

Reading state information... Done
msmtp is already the newest version.
Package mailx is a virtual package provided by:
mailutils 1:2.1+dfsg1-4ubuntu1
heirloom-mailx 12.4-1.1
bsd-mailx 8.1.2-0.20090911cvs-2ubuntu1
You should explicitly select one to install.
E: Package mailx has no installation candidate

:~$ chmod 600 ~/.msmtprc
:~$ gedit ~/.mailrc
:~$ echo -e "testing email from the command line" > /tmp/test_email

I'm from a Solaris (printer.conf) background and having trouble setting up a printer on the network. My CentOS box does not have a GUI interface available. I have been playing with lpadmin trying to add a printer - which it did, but everything is disabled, and the "enable" command is not found on my machine.
How do I make a simple printer on my network talk to my centOS box?
Here's the printer.conf from a Solaris machine that works:
raphael:
:bsdaddr=igppps1,raphael,Solaris:
And the printers.conf from the CentOS box:
lumina# more printers.conf
# Printer configuration file for CUPS v1.2.4
