Ubuntu :: Computer Restarts Before Going To Grub Screen Continually
Feb 16, 2011
I am having a re-occuring problem with Grub. The problem seems to occur about once every 15 or so times that I start up. Basically, it gets past the Samsung branded screen but before it goes to the Grub screen, the computer will restart - it just continually gets to this point and restarts until I shut down with the power button. The problem is easily fixed by re-installing Grub using an ubuntu CD. Things will then run fine for about a week and the same problem will occur.

I followed a tutorial to install XP across my entire HDD. I installed Ubuntu 10.10 "Alongside another OS". Ubuntu loads fine, but when trying to load XP, the boot screen shows up, but then the computer restarts and returns to the GRUB menu.
I saw some threads on this site and tried to type: sudo gedit /boot/grub/menu.lst
In the terminal. It returned a blank text document so I'm not sure if that information was outdated. I then typed: sudo fdisk -l
And got this:
Not sure what any of this means, but I sure hope someone else does. I would say forget XP, but it's hard to let go of some of the games and software I use. I appreciate any responses, thank you.
I tried to format the table as it appeared, but the forum corrected the extra spaces.

I installed Lucid Lynx some days ago. Whenever I try to access Vista from GRUB, the computer restarts. I haven't changed anything about how the computer starts.

I just dusted off my old Compaq Prezeio 900Z. Unfortunately, when I try to install Ubuntu, it screen freezes on me and the computer restarts.

I know this is an issue that has been brought up before and the solution I found is to recover Grub through the live CD [URL] However, this problem has occurred multiple times for me now. First time I thought it was just a freak error but it's happened multiple times within a short period of time (couple times this week) so I just wanted to get input on what's causing this and how I can fix it permanently. I've recently installed Ubuntu and I'm dual booting Ubuntu 9.10/Windows 7 Ultimate 64bit.

I don't really have any Linux experience. But I wanted to try it out. Now I'm afraid I did not set this up properly. Grub gives me 3 options:
Fedora (2.6.38.8-32.fc15.x86_64)
Fedora (2.6.38.8-26.rc1.fc15.x86_64)
Other
When I select <Other> to boot into windows... it starts to try to boot... but then flashes a quick blue screen & restarts. I tried to boot into Window's normal mode, safe mode, and command line... all just restart fdisk -l gives the following:

About two weeks ago I installed ubuntu 9.10 desktop with a dualboot to my windows 7, which was already on there. everything went fine, but I couldn't configure my wireless to work, so after a few days I gave it a rest and basically forgot about; I just stuck with windows. anyways, yesterday night I installed a program called solidworks on my system. I woke up this morning, turned on my computer, and this is what happened-
it turns on for about 5 seconds, but when it hits "grub loading", after about half a second it restarts. it's basically an infinite loop, until i throw in a cd or hit f8, but I don't know what to do with either of those options, so I'm kind of stuck.
I'm posting this in the ubuntu forums because I have NO idea what's wrong with it, and no idea of where to start. I've got both installation disks, but I don't know what to do when I put them in. I've got an intel pentium 4 processor, and like i said, i've got a dualboot with windows 7 and ubuntu 9.10.

this problem has really been getting at me, I can't figure it out at all. About a week ago, I came home from school and found that my computer was shut down (usually I leave it on), I started it up in Windows 7 and a Malware Bytes scan said it found a virus "clipb.exe". Well, I decided to remove it, and when booting up in windows it BSOD's saying IRQL_NOT_LESS_OR_EQUAL immediately at the login screen. Same result in safe mode and "last known configuration". Well, I decided to reformat just because I didn't want to go through too much trouble, and about a week later (today) it came back. I have no clue how, I was away from my computer. But the difference between this time and last time is, I can't start ubuntu at all. period. It gets to grub, and then after that gets to a black screen with no progress. The only thing I can do is ctrl+alt+dlt which restarts the computer.

I'm running Ubuntu 10.04, and ever since last upgrade a couple of days ago (I think), everytime I hit shutdown on the gnome-panel (admittedly, I haven't tried the command line shutdown) the computer restarts itself. This computer is dual-booted with Win 7, and the shutdown command there properly halts the system.

I've come across a problem just recently where my laptop will restart after I shut it down from within Debian. I've looked into my BIOS for anything that might trigger this, but could not find anything. I run Debian Testing 64-bit on a Dell Inspiron 17R laptop.

However that's about all that did. When I put the disk in and tried the demo and full installation option (or something along those lines), and then restarted my computer, it came up to the start up screen, and asked me if I wanted to run Ubuntu or Windows Vista. So I chose Ubuntu it came to the motherboard screen or whatever and that's it. Nothing else happened, I waited for about 20-30 minutes and it was still there.
So that's my issue, I tried the second option about installing inside of windows but for some reason I just get an error message saying I can't do that whenever it finishes loading. I'm trying to install the latest version 10.10, my computer definitely has the memory for it all

My laptop restarts itself frequently - full restart back through the bios screen to the bootloader, not just logging-out. It happens in Ubuntu 11.04 (32 bit and 64 bit), the Gnome 3 live CD from [URL] (the Fedora based one, run from a USB stick) and even from the GRUB bootloader menu. I have tried two different harddrives and two sets of RAM (all combinations) and the restarts still occur. They even happen when the hard drive is removed and Ubuntu 11.04 is booted from USB. Windows XP Media Center is also installed on the laptop too but the restarts have never happened when in Windows (even though they can happen in the bootloader!).
The memtest86 GRUB menu entry loads the blue screen with the title and memory info etc. but it seems to stop there and I don't think it's actually doing any tests, so I haven't been able to do a memory test. In Windows I have not installed any wireless network or 4-in-1 card reader drivers (among others probably), which is a possible reason why it does not restart in Windows, although I don't think GRUB has drivers for either of these devices either. My laptop is an Acer Aspire 5630 with the following hardware:
CPU: Intel Core 2 5500 (1.66Ghz)
Memory: 2GiB DDR2
Graphics: Intel 945 (integrated)
Audio: Intel HD audio with Realtek codec
Wireless: Intel PRO/Wireless 3945ABG [Golan]
It does seem that sometimes the restarts are caused by touching the keyboard (i.e. they happen exactly when I hit a key) but they also sometimes occur when I am not even touching the computer at all.

I updated a RHEL 4 system today using up2date and when the system rebooted it just said "GRUB" on the screen for a few seconds and then restarted (and did this over and over and over).
I booted from a rescue CD and was going to reinstall grub.
Here's the kicker: this machine has two hard drives configured with software RAID 1, and I don't want to screw up the mirroring by tinkering with grub.
/etc/fstab shows that /boot is at /dev/md0 but "/sbin/grub-install /dev/md0" doesn't work ("/dev/md0 does not have any corresponding BIOS drive").
I have a bad feeling that if I do "/sbin/grub-install /dev/hda1" that I'm going to screw up my mirroring.

I just installed the newest version of Xubuntu using the LiveCD, I chose to install it alongside my current installation of Windows 7, everything went well it seemed, but now when I choose Windows 7 under the GRUB menu it just restarts my system and then takes me back to the grub menu, Xubuntu works fine though and boots fine, I tried sudo update-grub, didn't fix it.Heres the boot info from a script I found, but being rather poor when it comes to diagnosing Linux, I figured it'd be best to post this and see

I'm having a really odd problem since I upgraded to 10.04 on my IBM T40 laptop. Every now and then, especially if I'm using Firefox (so it seems), I will be in the middle of something and suddenly I get a black terminal screen that flashes a few lines ending in "checking battery state" and I get bounced back to the login screen. I log back in and all my work is gone (Firefox and whatever else was open has closed). I was on the web for a while tonight and in a few hours it did it three times. I never had this happen before in 9.10.
Any idea what's going on? If it matters I'm on AC power when this is happening. I haven't used it long enough on battery to know if it does it then or not.

I come bearing a question that I hope I can get some info on. Here's the situation: I installed Ubuntu 10.04 Netbook Remix on my Acer Aspire One (didn't want it, but got it for free). I installed and am dual booting it with windows 7 basic. Both worked fine until this morning when the laptop ran out of battery and shut down.Now, on start up, the BIOS screen flashes, and its not the same BIOS screen, but I can't tell what it says, its moving too fast, the laptop then restarts. This problem may be bigger than the linux part of it

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.

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 using Ubuntu 10.04.1 and I run it 24 hours a day. Recently one morning I went to my laptop and opened the screen but the login screen wouldn't appear. Anytime the cursor appeared, HDD activity would go to 100%. I'm assuming this because the HDD light on my laptop was permanently on. So I made the dumb decision of just holding the power button down and turning it off. When I turned it back on, I noticed it came to a command prompt type screen listing "initramfs" at the bottom apparently wanting me to input a command. I did a lot of research and couldn't find much of anything that would help me. I read about GRUB, superblocks, fsck, e2fsck, etc.. . I tried all of those and nothing has worked so far. Any ideas? I did notice one thing. When I went into the actual install with the livecd, it told me the drive was /dev/sda5, but in Disk Utility on the livecd, it told me it was /dev/sda1

i recently installed ubuntu 10.10 64-bit on my laptop and installed all the drivers and updates i saw. When i first started it up my top panel was a solid gray and had a classic look, i saw online that i had to do Alt-F2, type gconf-editor then go to apps,panel,global click locked down, then i log out, log back in and it is fixed with my system theme. after i restart my computer it has the same classic look, and i have to go back to gconf, log out, relog, log out, relog and it finally works. why is it doing this?

My Ubuntu 10.04 freezes continually when it starts accessing the HDD. I will be working normally, then when i switch windows, it will suddenly access the HDD and spin up for 4 to 7 mins. I can't access anything during this period. The processor is generally only 1-5% impacted during this. I think its accessing the swap.
I admit, it's an older computer with only 2gb of RAM. Wondering how to debug this and if I should install an older version of Ubuntu to fix the issue. I've tried three different harddrives, so i know it's not errors on the disk.

I use Firefox, and Firefox has been crashing like crazy on me for the last few weeks. Does this constant crashing have anything to do with not being able to update from synaptic?

I'm just having a bit of trouble with activating my wireless card (see title for details). rfkill - I installed it but nothing was soft / hard blocked (whatever they mean). I did the rfkill unblock command anyway but it didn't appear to change anything Tried doing it manually through system-config-network but this yielded no luck either. Basically all it does is continually ask for my WEP key, even though I've typed it in correctly a million times. why I don't have WPA2 because I do not have the ability to change it

Running Debian GNU / Linux 5.0.4 on an older Gateway tower. Have been using this for a year now but it seemed lately that the browser was loading pages slowly. I checked the Network Icon and every time I check it indicates "disconnected" then refreshes and indicates connected. The log makes references to redat, which my machine has nothing to do with? I checked the system logs and get the following repeated messages:

10.04 and Nvidia video card.
This sequence:
sudo apt-get purge nvidia*
sudo apt-get install nvidia-current
sudo update-alternatives --config gl_conf (not sure what to choose, I just pick an option at random)
sudo ldconfig
sudo nvidia-xconfig
and then restart gets everything apparently working correctly, with my desktop spread across two monitors.
However, after two or three computer restarts, it 'forgets' and defaults back to low graphics mode and all the common error messages mentioned in multiple threads here, with my second monitor just duplicating the primary monitor.
Under System-Hardware drivers it says Nvidia_current is activated but not in use, regardless of whether it starts normally or in low graphics mode.
What's up? It's a pain to have to go through that sequence over and over again, and then restart my computer every two or three days, and leaving the computer on 24/7 isn't an option. power saving and all that.
