Ubuntu :: "GRUB _" Appears At Startup & Fails To Boot?
Mar 29, 2010
A couple weeks ago I installed Ubuntu Security and Recommended Updates that included an update to Linux Kernel 2.6.31-20. Upon installing these updates I was prompted to restart my computer for the changes to take effect. So I rebooted and encountered a Hyper Transport Sync Flood error each time I tried to boot, preventing me from booting into the OS.The above linked forum thread about the error suggested I manually adjust voltage settings in the BIOS to resolve the issue, so I gave it a try to no avail. Then I decided I would just reset my BIOS settings to the defaults (seeing as I hadn't edited that many settings to begin with). After doing so, I tried booting only to encounter a black screen with "GRUB _" printed on it.
I have encountered this issue before when I initially installed Ubuntu 9.10 on my system, but I'm not sure whether this occurrence is strictly BIOS setting related or if something effected my bootloader. (On a side note, resetting my BIOS settings to defaults seemed to, at least for now, eliminate the Hyper Transport Sync Flood error I was getting...and instead leave me with another problem.)I used this script created by meierfra. to provide info on my current boot setup, the results of which are displayed below.

opened the system>administration>bootloader guior anything just opened it)now on boot I get a timeout with an option to go to the grub configuration or boot my one and only installed versionwould really like to get rid of that and go back to booting straight to my only fedora version installed without the option to go to grub (might be useful someday, but now is not the day
Two days ago I decided to migrate from Fedora to Ubuntu 10.04. On the Ubuntu install I chose to format the entire disk as I do not want a dual boot system. I have three disks and have set the bios to boot from dvd, then main disk, then 2nd disk, then any other bootable drive and coming from a working Fedora I know I have my "slaves" and "Master" pin positions on the disks set correctly.
When I try to boot the fresh install of Ubuntu I do not see any menu options, no boot image nothing, I get taken immediately to a grub command window and I dont know how to fix things from there. I have tried to fix things by booting into the "try before you 'buy'" thing on the installation cd and I can see that Ubuntu has been installed on the main disk, but all in all Im stuck.
I recently removed Winblows Vista from my laptop and replaced it with Kubuntu 10.10 (I left the recovery partition on there, just in case). When I turn on the computer, the GRUB menu appears, I press enter, then a little flashing underscore appears on the screen in the top left hand corner. After a few seconds, the Kubuntu logo appears and I can log in.But yesterday I replace Kubuntu with Ubuntu 10.10. The Boot process is the same, but the little flashing underscore in the top left hand corner flashes for about 10 seconds longer then Kubuntu 10.10 did, and then a few paragraphs of text appears for a few seconds, then I am logged in automatically.Is this "unusual" boot process anything to worry about, or am I just being a noob.
My dell machine has the following: A raid 0 SAS config with Windows 7 installed in one partition, and ubuntu in the other partition. Then two seperate sata hdd. The raid drive is set as first boot, and Windows views it as disk 0 and boots just fine. When I installed ubuntu 10.04 on the second partition, it viewed the disk as sdc. And when booting off the raid drive,im not given a grub menu to choose ubuntu orwin 7,windows 7 boots all on its own.
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.
Just delete a linux partition and now when i boot a message appears and says error: unknown filesystem grub rescue >
I have search on the net for this problem and i have understand it a little. But my situation is a bit different and because i don't want to format my hard disc i wanna try to fix it. So before a couple months i download ubuntu 9.10 and i installed it a month later. But my computer used to crash all the time and i couldnt use it. So i download the latest ubuntu 10.4 and install it while having windows xp and the old ubuntu 9.10(so i had windows xp, ubuntu 9.10 and ubuntu 10.4 partitions). Now i tried to delete the partition of ubuntu 9.10 from disc utility. so i have the message i wrote above when i boot. I dont wanna delete my windows xp and ubuntu 10.4. what should i do to stop this message from appearing.
I just recently put Ubuntu 10.10 for ppc on a Cd-R and installed it onto an old Mac I had found. The installation seemed perfectly fine I booted the computer and was presented to boot with two options "Linux" and "old" or to press enter and boot default. I had decided to boot default and it reaches the splash screen where the loading bar advances two dots and then completely stops.
After certain system-wide changes, like kernels updates, I obtain grub prompt on restart. However, if I put the hard drive into another computer (b), it boots up fine. Since, however, I use the present computer (a) regularly, I only use b to purge and reinstall grub using the chroot method. However, doing so every time is time consuming; and I cannot change anything in the defaults and run update-grub without obtaining a grub prompt on restart. How do I fix this?
I am inexperienced in using Linux, and just installed Ubuntu 10.10 on an external hard drive. I didn't want to mess around with re-partitioning my hard drive, which has Windows 7. I figured that I could just run Ubuntu from the external, and if it gave me any problems with Windows, which I unfortunately need for work, I could just unplug it and boot normally. However, GRUB appears to have installed some component to the local hard drive. Whenever I try to boot from the local hard drive, I get this error message: "error: no such device: 8b84f351-7770-4908-b12f-0cbd31bc3662 grub rescue> " Another thing is that in the boot menu, only the CD/DVD drive and local hard drive are options, it won't even register the external. Any suggestions on what may have caused this error? I saw from other posts that GRUB doesn't like multi-drive systems. Also, would it be possible to delete GRUB from my system, then allowing Window's MBR to take over?
i have installed ubuntu 9.10 inside windows vista.now when i start my system i get option to select windows or ubuntu. windows can start successfully but ubuntu start up fails and give grub shell prompt as :
I have installed Ubuntu 10.04 LTS-the Lucid Lynx on top of a Windows XP installation. The Windows partition started before I did this. Now, all I get is a flashing cursor when I tell GRUB to start the Windows XP partition.
I have tried reinstalling Ubuntu with no effect. I have tried repairing Windows using a Windows installation disk.
However, I can reach the files in the Windows partition just fine from Ubuntu.
ubuntu 10.10/wubi/asus 1201ni have installed screenlets via synaptics and added two screenlets to my desktop.i added screenlets to the autostart menu, pointing it to a folder inside my documents folder, where the launching icon of this software is located.since then, after reboot a gedit window appears on my desktop and says the following :
I installed karmic, then damn small linux - the DSL's loader would not recognize my xubntu automatically, so I got GRUB 1.97 on xubuntu and it recognized my DSL and added it to the menu with 3 alternative resolution options.
Now, xubuntu starts fine, but when I start DSL in any of the modes, I get the following output:
1. 'vga=normal is deprecated use gfxpayload=text before linux command' comes up in the same font as GRUB menu is displayed - but only for a split second, I had to video it to read it!
2. Uncompressing linux... ok, booting the kernel - similarly, disappears before you can read it, and the computer reboots.
Below are my /etc/default/grub and /boot/grub/grub.cfg.
Does all that mean I want to edit /boot/grub/grub.cfg even though I apparently must not?
NB I have some problems with my hard drive, I have to fdisk it a lot but that's probably because my laptop has a dead BIOS battery - I'm having to fdisk it every time I boot up etc. I'm a bit lost with this to be honest! Anyway, please forget the hard drive note unless you seriously suspect it's at fault for GRUB problems.
I'm using the RAID1 setup, which is configured in the BIOS, as it is a HP Proliant server. i have 2 500GB hard drives configured in a mirror. when booting the install, it recognises this, and deals with it fine.
The problem is, when it gets to the section of installing the grub2 boot loader, it just stops and gives me the "ubuntu installer main menu" where if i select grub boot loader install it just loops back, and if i select LILO installer, it errors, saying an installation step failed.
It has the option to skip installing boot loader, but then, can i get it to boot a different way? can i boot manually into the server install and then install GRUB and hope it works? can i install grub1 rather than grub2?
I am a complete noob at this and I need a hand. I was about to throw my computer out of the window when I decided to throw the windows out of the computer so to speak. So, I downloaded Ubuntu 10.10 and tried to install. I had a grub rescue after the installation (file system unknown), which I have seen discussed here. Being the noob that I am I decided to try 10.04 because it said it had full support. With this install I get a similar error during installation: grub cannot be installed in boot sector.
So, basically there is an issue with grub and the boot sector. I checked in my BIOS options to see if there was an option that prevented the writing of a boot sector or something, but I have not been able something like that. So, I am wondering if it is possible that Ubuntu does not really erase/format the selected disks or something, leaving any difficulty there.
Does anybody know? Or better yet: what exactly do I need to do a manual grub install?
On my PC, I use GRUB to manage my dual-boot startup on my PC. Every time I update my Linux, It adds another 2 startup options on my HD for every distro I have. (The Normal and Recovery modes for the new version.) I would like to add the VortexBox distro someday.
Is there a way for me to get rid of the older versions of Linux distro's on my GRUB menu so I just see the newest? I have 6 options for Ubuntu 10.10 and 4 options for UGE 2.8..
I don't know why its called "GRUB 2" while it is actually GRUB 1.98 or 1.99. Anyway.So here's the thing. Due to the fact that I am dual-booting Ubuntu + Windows XP, my GRUB menu would show up during boot with or without me holding down SHIFT. This takes several seconds. What I'd like to do is that GRUB does not show up at all during "normal" boot and only shows up when I hold down the SHIFT right after BIOS POST.
I have a ~ 2008 notebook (Compaq CQ60-137EL) on which I had Windows 7 only (it was sold with Windows Vista installed).
Later I installed Debian Jessie 8.2.0 Stable ("Graphical expert install" from DVD), along with GRUB as a boot manager (I chose not to install it on the EFI removable media path).
Since then, if I select Windows 7 on the GRUB boot screen, I see "Starting Windows...", and after few seconds the screen flashes for a moment, and then the PC reboots: I see the bios screen, followed by the GRUB screen again. What's even more weird about this is the fact it just happens only in like ~50% of the cases. In the other 50%, Win7 starts flawlessy.
I even tried to install Debian first, then Windows 7, then re-install GRUB, but I got the same issue, even with both system freshly installed.
On 6 attempts, 3 times it worked and 3 times it didn't.
On my desktop PC I'm in the same setting, but I don't have this issue. I think it may be related with the fact I have Win7 on a SSD and I installed Debian on a separate HDD, while on my notebook, as you can imagine, there's just one single HDD.
I had a minor problem with my ubuntu install, and a person said to go to startup manager and select reset to original settings. I did this and when I restarted It asked me to boot ubuntu 9.10, which would not work as I upgraded long ago. Now all I get is the option to boot 9.10, and I really want to get back into my computer. Running ubuntu 10.04 with latest updates as if 25 september New Zealand Time.
I recently purchased a new Lenovo Thinkpad T420i and am having problems installing the latest version of Squeeze from CD. After receiving the laptop, I started it up, configured Windows 7, and confirmed everything is working correctly. Next I went through the Debian installer, which completed successfully. I'll be dual-booting Windows 7 and Debian, so at the partitioning stage I resized my NTFS partition, added a shared VFAT partition, then used the "Guided" install to create my root and swap partitions. My partition layout is code...
I assumed something was wrong with grub, so I booted the CD into rescue mode and chose to reinstall grub onto the Master Boot Record. But nothing changed. Just to experiment, I went into fdisk, deleted all my new partitions (leaving just the Windows ones), and tried rebooting, but the same error happened. I then went through the Debian installer again, being careful to set everything up correctly, but still, the device won't boot.
I'm not even getting to the grub boot screen, so something is wrong even before the point. Reinstalling grub to the Master Boot Record (grub-install /dev/sda) isn't changing anything. How can I troubleshoot this?
Downloaded Ubuntu 10.04.1 Desktop AMD64, tried to install it to a cleand HDD using the whole HDD, i.e. gave it permission to use the whole HDD. Installation process appeared to run OK but when it came to the restart it just fired up the message
error: out of disk grub rescue>
I've searched this forum and found numerous references to these error messages but cannot make head nor tail of the diagnostic suggestions. Apart from anything else they suggest strings of command lines which I don't understand and can't enter anyway since they don't correspond to my keyboard layout (if I hit > or ) something completely different appears on the screen). Is there someone here who can provide a step-by-step solution in lay language ? Or is there such a thing as a bootable file which can be downloaded and inserted into my CD drive to correct this problem ?
I have a laptop with Karmic Koala in dual boot with Lenny. I need to reinstall Lenny however if I do that I will loose Karmic Koala in the grub screen because of the new version of grub that comes with Karmic Koala. Which means that I will need to reinstall Karmic Koala after Lenny so that they both appear in the grub screen at startup. If I reinstall only Lenny is it possible to use Gparted to change the boot back to Karmic Koala and have them both in the grub screen again? Or is there another way around it?
OpenSUSE is starting to drive me a bit nuts. Actually what I'm trying to do is simply install VMWare server on a recent as possible SUSE and run 2 virtual machines, both the same SUSE. Of course 11.2 32 bit doesn't run VMWare server 2 so it's back to 11.1. The trouble is, 11.1 won't install properly on my PC.
The install process, booted and installed from the 11.1 network install iso image on CD, runs fine. The PC reboots from hard disk and stops at the grub prompt. I've tried the auto-repair option and reinstalled it from scratch a second time always with the same results. It seems the root partition is hosed, and that's where my understanding hits its limits. Can anyone help?
Incidentally should anyone be able to advise on the VMWare conundrum I'd also be interested. Maybe in another thread...
It seemed that it would be simple enough: take the 'f' option in the expert menu of fdisk to put partitions in order after a gap had been created by a deleted partition and then make corresponding changes in /boot/grub/grub.conf because the root partition was shifted.
Well, it didn't work out that way. No matter what I try, I either see the error 15 at Stage1.5 or the error 28, which is even stranger (file does not fit into memory). All this before I even see a grub menu. It just does not get that far.
Does anyone want to take as stab at guessing what might have happened here and whether I have a chance at recovering without having to reinstall? I can provide concrete data, if anyone would be kind to give it a try. Hoping that this is a known problem and something can be guessed from what I stated here but I can be as specific as needed, just don't want to generate noise if there are no takers.
I have installed a new Linux distro (just to test it) on my usb memory stick, and I'm trying to run it. I don't know if what I did is correct so far, anyways here's what I have:
Grub on sda (internal hard disk) sdb with no boot loader (memory stick)
In grub I've been doing: root (hd1,0) kernel /kernel-genkernel-x86_64-2.6.37-sabayon root=/dev/sdb1 vga=normal initrd /initramfs-genkernel-x86_64-2.6.37-sabayon boot
This seems to work (as opposed to when I forgot the root= parameter, which almost destroyed my linux on sda1 ), but during startup the system complains about no root bein found on /dev/sdb1. I also tried (hd1,0), but it didn't change much.
I'm sure I can boot an OS from usb on my computer, so doesn anyone know what I'm doing wrong?
I just tried installing OpenSUSE 11.1 onto my Playstation 3. I installed the otheros.bld fine (which I downloaded via a link provided on the OpenSUSE website). I then inserted my 32-bit Gnome CD for installation and restarted my system. Then on startup, a blue/grey screen appears. Here are the links to the screenshot (sorry for poor quality):
[Full Screen] [url]
[Top Half] [url]
[Bottom Half] [url]
As you can see, the only option is for me to select the gameboot, which obviously takes me back to the Playstation XMB. There are keys at the bottom of the screen, but this is only to change the resolution. So I have no option to install the OS.
Does anybody know why this screen appears and have any ideas on how I can get around this problem to install SUSE onto my Playstation?
