General :: Netboot In GRUB - Enable Boot Command ?
Jan 6, 2011
I am trying to use netboot functionality available in GRUB(legacy). I just compiled GRUB with --enable-diskless and --enable-rtl8139 options and installed in USB flash drive. I am getting the grub prompt when tried to boot from that USB. But not getting boot command..what i need to do to enable boot command??
I have just installed ubuntu 10.04 via a netboot install.When my system reboots I only have the command line - no gui. Could someone kindly inform me what command I need to run in order to get a GUI
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:
Alt-SysRq-e - Requests kernel kill all processes except init.
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 have Microsoft Windows Xp installed on my Primary Drive C: and I had a Mint boot disc that I would pop in and load from. Well I got tired of this disc and installed a new hard drive in my computer so I could use Mint as a secondary OS. Everything went good in the install, and I put Mint on the second drive. But when I boot my computer the GRUB menu only shows Linux Helena Mint 8 to load from and no Xp. Xp is still currently installed on the computer in the Primary drive, but how do I inlcude it in the GRUB boot menu or boot it at all?
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 have a windows 7 hard drive as Sda0 and have a second hard drive as Sdb1, which is where I want to install OpenSuse 11.4. Now here is where I am not sure on the install, so I don't screw my self up. I have 100mb partition on sda0 that windows 7 is using, do I enable grub or have the boot write to MBR?
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 am able to get into GRUB and boot Linux, but whenever I select Windows, all I get is an error about a missing boot loader.
After the Windows install disk failed to repair it, I reinstalled the Windows system and then used the Ubuntu live-CD to restore GRUB in order to be able to boot into Linux again. Now I have the same problem as when I started (although the error screen is somewhat different now).
Does anyone know how to break this "evil circle" of mine?
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.
I've only recently learned how to use the "Multi_key" function of the X windows system... I learned how to set a compose key from: [URL]... Which I found via google. It gave both directions for defining a compose key in the xorg.conf file. which method did NOT work for me on Arch Linux even after a full reboot. I'm not all that concerned about that however, because I find the temporary setxkbmap method more appealing anyway. A simple ~/bin bash script which if $1 begins with -h will less /usr/share/X11/locale/en_US.UTF-8/Compose and will otherwise run the command
[code]...
IF I use the above setxkbmap command to enable a Multi_key, is there also a setxkbmap command I could issue to disable it?
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.
How can i enable caps lock by using echo command. I know that by using syntax echo -e "33[3q" this only turns the capslock led to glow. but the capslock is not working i.e. the words are typed in small case only.
Then by using xmodmap command i.e. syntax xmodmap -e "remove lock = Caps_Lock" or xmodmap -e "add lock =Caps_Lock" doesn't work. On running this it shows unable to display.
I have install RHEL5 and created normal user as "test". When I login as root user, I can run crontab command but when I login as test user, I can't run crontab command and throws error as "cron/test: Permission denied". how to enable crontab command for test user as well?
I am using Fedora 14. By default Security Enhanced Linux is enabled in Fedora 14. Now is there any way to disable it by command line and then again enable it through command line.
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'm running Debian testing and after a recent software update, suddenly I can no longer boot into my single Linux kernel image anymore. I did look at the software update before I did it and I don't believe that it removed any software packages. When I try to boot into my linux 2.6.26-1-amd64 image, I get the following message from grub:"error: unknown command `initrd'"..The same error appears if I try to boot into single-user mode. I have a Windows XP partition on the same hard disk and I am still able to boot into that from grub. I've searched the net and haven't really found my same problem replicated anywhere. I would imagine that the problem is just that somehow the initrd package got removed in my last software update, but again I don't recall seeing any software that the update planned to remove.
Any thoughts on how I would go about fixing this problem? Since I'm unable to get into Linux at all, I imagine I'll have to use a LiveCD to get in and fix the problem, but I don't know where to begin looking.
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
I have been trying to install Ubuntu by network booting, I used tftp in Windows in another pc, and the target boots successfully but fails to download from any archive mirror, I'm not sure what goes wrong.
Well, I'm trying to do is, my friend's HP-mini fails to boot to Windows, and BIOS also gives error-messages, the thing is that my friend has important data on his netbook, it has only one drive, no cd-rom, and it doesn't support USB-booting, so I was thinking if I get to access an Ubuntu, I will be able to backup his data and install Windows, I would use anything that would let me copy files.
I have a bootable usb stick with a Linux utility on it. After poking around for a bit I figured out the boot order:
isolinux.bin <--reads isolinux.cfg loads the kernel: SA.1 loads initrd: SA.2
then depending on the options you select it boots one of two .iso files I want this utility to netboot instead of booting with a usb stick; is there a way I can package isolinux.bin, isolinux.cfg, the kernel and initramfs, iso's and all the other files on the root of the usb stick into one iso that can be tftp'd to the host which would then boot something that would extract the iso to ramdisk and start booting so that isolinux would run as if all the files were locally stored on CD/usb stick?
after the third time downloading the netbook and installing to sd and or usb i decided to check the md5 but where is the md5 the new download pages bites.. wheres all the mirrors/ the new desighn is a good at waisting space //wheres the md5? bring back ftp style downloads?
I am very interested in using CentOS as a server for diskless PXE booting and was wondering if this was a possibility. I have a working DHCP/TFTP/HTTP system set up and going and I can get my client machine to boot a linux image without any problems. Ideally I would like the diskless machines to be able to immediately load an image through PXE and store their own filesystems on the server through the use of NFS.I heard about system-config-netboot and got very excited because it sounded like something that would help me set up a diskless system. However, after doing some research I have heard from many that it is generally buggy and unlikely to work. When I tried using it I got the error: "The diskless directory must be NFS exported and contain a boot sub-directory"Even though my diskless directory WAS nfs exported and most definitely contained a boot sub-directory. Does anyone have any advice on using this tool, or using CentOS as a server for diskless clients?
today i changed my grub boot order, and to make that work i need to do sudo grub-update.however, it doesnt work. does anyone know why, maybe the command changed?
