On a few VMs. Sometimes, when powering them on I get the GNU GRUB menu...
Code:
GNU GRUB version 1.97~beta4
Ubuntu, Linux 2.6.31-14-generic
ubuntu, Linux 2.6.31-14-generic (recovery mode)
Memory test (memtest86+)
Memory test (memtest86+, serial console 115200)
etc
But there is no countdown for a default boot. It just hangs here. Indefinitely. Until I make a choice by pressing the enter key with "Ubuntu, Linux 2.6.31-14-generic" highlighted (default). I don't know if this is because the VM may not have been shutdown properly or what the case is, but this is unacceptable as I need these systems to continue to boot and get back on line regardless of the reason they were powered off.
I saw a similar thrad, but can't find it anymore. Anyhow it was not resolved. So I take the liberty to post this in a new thread: I have installed ubuntu 9.10 on a laptop in dual boot configuration (other OS is WinXP). grub starts and I can hit enter to boot Ubuntu. However as soon as I use an arrow key to move downwards in the menu, grub hangs. In this condition I cannot boot any other OS, not even the "safe" version of Ubuntu.
Any idea what is the cause of this? It is a fresh installation and I read in the other thread that reinstalling grub or re-running grub-update had no positive effect. Does anone know how I can install grub 0.97 ? Where do I find it?
i have ubuntu 10.04 and xp installed in two different hard disc partitions. everything was fine until i came from vacation and found that after turning on my pc it gets hang as soon as the grub menu with duel boot option appears. i cant do anything at that stage, just nothing.keyboard doesn't work also. here one thing to be mentioned that for last few days my pc used to hang frequently in ubuntu 10.04 and then i had no option left but to restart my pc.
About a week ago my netbook (Samsung N220) stopped booting, after been working fine since installing it 4 months ago - not aware of any changes, though some updates may have been applied. It is not getting to the grub menu and instead just getting a flashing cursor in the top left corner of the screen. Booting fine from a USB, and the bootinfo results.txt is:
Code: Boot Info Script 0.55 dated February 15th, 2010 => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #5 for /boot/grub. => Syslinux is installed in the MBR of /dev/sdb sda1: _________________________________________________________________________ File system: ntfs [Code]...
I'm relatively new to Linux and I am dual booting Ubuntu 10.04 LTS and Windows XP and I would like to edit my GRUB menu to allow me to choose Windows XP which is on a 2nd hard drive. But, I can find no menu.lst and there is no GRUB menu while booting up, my computer boots right into Ubuntu. So, how do I enable the boot menu so that I can edit it and use it?
I have two versions of Ubuntu on my computer - 10.04 and an earlier one that i no longer use. I'd like to free up the space that the old partition is taking, but the computer boots from the grub menu.lst of that old version. How can I make the boot process use the menu.lst in the 10.04 partition?
where is the boot process situated anyway and how can you get at it?
I had Ubuntu 10 running on vmware machine. It ran fine. I upgraded to version 11, but now when the machine restarts I do not get any menu, I just get his: GNU BRUB version 1.98-1ubunutu7 Minimal BASH-like line editing is supported. grub>
And that is it! No menu, no list of options, nothing. If I type "ls" I get: (hd0) (hd0,5) (hd0,1) (fd0)
I can enter "root (hd0,1)" which gives me: (hd0,1): Filesystem is ext2.
Then typing "kernel /boot/vm" and pressing tab shows: vmlinuz-2.6.32-27-generic vmcoreinfo-2.6.32-27-generic vmlinuz-2.6.35-28-generic vmcoreinfo-2.6.35-28-generic vmlinuz-2.6.38-8-generic vmlinuz-2.6.38-8-generic
There is no /boot/grub/menu.lst but there is /boot/grub/grub.cfg which seems fine as far as I can tell. Did I somehow end up with an older grub which is looking for menu.lst? I have other machines running Ubuntu and if I boot into them I seem to get a GRUB4DOS etc. slightly different version. The grub version shown above is 1.98 but I read somewhere Ubuntu uses version 2? Actually I found another post which suggests that this is the correct grub version for Ubuntu 11. How can I tell what menu file grub is looking for where it is looking and why its not finding or using it? It should work...
My dad has done something to his comp and it won't boot. it stops on boot up an comes up with some sort of black screen command line. he said its something along the lines of "initramfs" and he can't seem to do anything. We tried booting to the recovery console from the grub menu and gets the same response.
Hes having trouble booting to cd at the moment so I need to know is there some sort of command that will fix or at least give some help that he can type in from this spot.
i could not change the sequence of dual booting from the grub menu.lst, due to it shows a blank screen when i put the command in the terminalayan@jayan-desktop:~$ sudo gedit /boot/grub/menu.lst [sudo] password for jayan:
Recently I installed Debuan "jessie". I previously had Windows 8.1 and Xubuntu installed. After installation Debian installed it's own version of GRUB, with entries for Debian, Xubuntu and Windows. The problem is that after I selected Windows when booting, GRUB menu no longer appears. It boots straight into Windows.
It's lenovo Ideapad z510 laptop, with special button that allows me to select between 4 options before booting - one of them is "Boot menu".
I didn't use it before windows "removed" GRUB, but now there are 2 options: Windows boot loader and Ubuntu. When I select Ubuntu it loads my old boot menu (from before installing Debian).
I thought that when I use update-grub from Xubuntu I will at least eb able to boot into debian. After I did that Debian option appeared in the GRUB menu, but it didn't work - black screen.
How to get GRUB menu working again (and avoid replacing it by windows boot loader)?
Here's exracted from ubuntu Grub2 document https://help.ubuntu.com/community/Grub2:
GRUB_HIDDEN_TIMEOUT=0 This setting determines how long a screen without the GRUB 2 menu will be displayed. While the screen is blank, the user can press any key to display the menu.The default behavior is to hide the menu if only one operating system is present. If a user with only Ubuntu wishes to display the menu, place a # symbol at the start of this line to disable the hidden menu feature.According to above information, I have tried to set below in order the show the menu:
New to Ubuntu and trying to ensure I can boot into Acronis Recovery Manager to be able to reimage Windows as and when appropriate. If I enable the Acronis Recovery Manager so that it overwrites the MBR then I run out of ROM I think which prevents it from loading. If I use the software CD that doesn't detect my sata drive. However, I made a rescue CD in Acronis and this does work but I'm only using my bootable CD drive temporarily in this system.I found this post (URL...) which seems to do what I would like and have managed to follow this to extract the files from my rescue CD into /boot/acronis. However this original post relates to Grub and as a newbie to Ubuntu I think I have Grub2. I can't figure out what the correct syntax is to make a new Grub Menu entry in /etc/grub.d/40_custom.
i have lucid lnyx installed as my main system and added natty on a seperate drive. after installing, the new grub detected lynx & i was able to boot into each without any problem. after doing some tweaking on natty (changed run level), it didn't boot properly so i reverted to the old config via rescue disk. after rebooting, the old grub menu didn't show & it loaded lynx automatically.
i tried the suggestion from another post changed the hidden menu and updated grub but it didn't detect natty (below).

I'm very new to Linux but when I first installed it, I downloaded the Start-Up Manager so I could change the boot order. I have a dual boot Windows-Linux, I set the default as Windows. Recently my computer started booting to the system memory test in the grub menu instead of Windows. When I try to open the Start-Up Manager now it asks me for the password as usual and then does not start. How I would change it back to windows for the default? I'm running Ubuntu 9.10.
I have just updated my Ubuntu linux to Ubuntu 10.4, not my grub menu isnt letting me boot to Windows Partition.The problem seems to be with grubs new update from using an editable menu.lst file to using a non editable grub.cfg file. Everywhere I look it states "DO NOT EDIT THE GRUB.CGF FILE". I am at a loss as what to do. I figured that the new configuration has screwed up the Windows Boot File. Anyone have any suggestions on how to fix this. I am not sure if it is a windows issue or an issue with the Grub boot menu.
Debian if my first OS and i want to dual boot Fedora12.Ok i installed Fedora12 and choose not to install the bootloader(gonna use the one Debian installed)What i'm tring to do in Debain is edit my /boot/grub/menu.lst Here is what i have
I'm currently trying to get to the root of an problem on startup; unfortunatly when booting after the first couple of messages when booting without quiet and with nosplash in the grub menu I still end up with the nice blue background and the slowly filling bubble... I'd like to go back to the old, boring, messy, but much loved and now much missed (least by me) text boot screen where I can see wtf my system is doing and where its hanging during the boot process.
(I know the cause of the hang now but still want to go back to the old fashioned noisy boot environment - not a fan of the windows style silent boot... I like to know what's going on and that my PC hasn't decided to join the French and go on strike, though wouldn't blame my poor netbook if it has, hammering the bleeper doing random number analysis - not something an atom 270 is designed for)
I am testing my crash recovery strategy for my linux system and I am having trouble with GRUB. I am basically restoring my backup (i.e. tar) unto a different hard drive, but I am having problems getting the machine to boot without me having to type the GRUB commands at the GRUB prompt that is presented when the machine boots up off the new hard drive. I have tried to restore the MBR in two ways (the 2nd one is the one that gets me to the GRUB prompt):
1. Get the MBR off the original drive and write it unto the new drive (all via dd), but that did not work at all: the machine hangs right away during boot up. It seems to hang right at the point where the BIOS tries to read the MBR.
Code:
On original drive:
# dd if=/dev/sda of=mbr+part.bin bs=512 count=1
On new drive (new drive is now in place of original drive):
reboot and remove FEDORA CD Using the 2nd option above, I get the GRUB> prompt during bootup. I can then boot into the system by issuing the commands that are in the menu.lst file, followed by the "boot" command. However, I would like for those commands to happen automatically, just like in the original configuration. It seems to me that GRUB is actually finding all its stage files because I doubt the GRUB program (the one displaying the prompt) fits entirely in the 446 bytes it has on the MBR. So, it must be loading its stage 2 (and stage 1.5??) files from my /boot partition. However, if GRUB is loading its stage files off the boot partition, why does it not load/read the menu.lst/grub.conf contained in the boot partition also?
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 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 requested a Live CD from ubuntu. when it arrived i booted from it to try Ubuntu without installing. i booted from the live CD for about 5 times. now when i want to install Ubuntu it just hangs when the booting screen appears (when its written Ubuntu and 5 dots are flashing behind the word) now i dont know what is the problem, i have also tried a different CD-ROM but same result. the CD is new/ scratch less but it just wont boot. hangs up all the time. Now i dont know how to install Ubuntu. 1- i can make a bootable USB. i downloaded the ISO and made a bootable USB with Universal USB installer, set my computer to boot from removable but that too didnt work. 2- or i can write my own cd. i will do that but i just wanted to find out why the CD doesnt work after working for 5 times.
I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code: menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod part_msdos insmod ext2 set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?
9.10 has no menu.lst file and hitting ESC to does not bring up the grub menu. How can we set bootup options or boot an alternate kernel? I would really like to set the resolution at boot time so that my console (Ctrl-Alt-F5, for example) has 80 columns instead of 40. (What a stupid default, gigantic Commodore-64-like text!) It would also be nice if the Login screen could be set to the resolution that I want.
In previous releases, there were ways to do this. In 9.10, I haven't been able to figure out how.
Is there a document explaining all of the radical changes?

i m trying to install ubuntu 10.10 on my desktop from usb it hangs when booting so i cant even install it and if i try a diffrent flash drive does nothing but the odd thing when i use unet-bootin it boots up but i get an error on the install Note: i am on 64bit os and my only option is usb
I'm running Maverick on an Acer AO521 netbook. I've got a k125 processor and an ATI Mobility Radeon HD 4200 series video card.Since upgrading to 10.10 with the new version of gnome my computer has started getting stuck on blank screen when booting the GUI. Not every time, but most times i boot.If I boot to command line through GRUB there's no problem. When I try to run gnome from the command line i get the same problem.
Just upgraded to 10.04 from 9.10. upgraded from update manager. System would not boot. Booted live cd and used the 9.10 menu.lst. Now boots but takes a long time. I don't know much about the kernel. I assume they are listed in the /boot directory and are called by menu.lst (dual boot w/ XP) (btw: I am ready to get rid of XP once I get this fixed). 9.10 appears to use 2.6.31-20-generic, therefore, I assume 10.04 uses 2.6.32-25-generic.
is it ever possible to do dual booting with grub(legacy) ever at all!. it is possible provided i take some pain, here is the link of that post [URL] i was coward and weak i didn't try that out then. but i did try it out. now so if u haven't seen the post .... I've installed Fedora 15 desktop(Gnome) with physical Logical volume called vg_fedora lv_root(ext4) ,lv_swap and lv_home(ext4), with 500MB /boot partition and had about 200GB free hard disk space ... so i wanted to install Scientific Linux 6.1 (because our school uses RHEL 6.1)
so, while running the installer I made (added) a logical volume lv_Scientific with ext4 FS and made its mount point (/) and used the MBR /boot which overwrote the Fedora /boot (completely OK and was as expected) i restarted after installation i got SL log in and as per the directions of the thread i copied the boot stanza from grub.conf of fedora 15 (which i already had copied and pasted into a text file and copied it from there)and pasted it into grub.conf of SL you may ask why did i choose same physical LVM too save swap space ... if i had made another physical LVM i had to make another swap ( i like LVM ... its cool)
completely unexpected happened Fedora now boots but not SL when grub starts i get this error 27 unrecognised commad and when i press <enter> i get grub menu with SL and fedora when i press on Fedora it works well i get my fedora login and i did login .. everything works fine but when i press SL it goes to the previous black screen grub error 27
