Ubuntu :: PC Restarts After Booting From DVD / Stop It To Do So?
Jul 31, 2010
I'm a WuBi user, and wanted to upgrade XP to 7, I've upgraded it partially when in XP. So as expected he messed up my grub.
But now I have the problem:
Every time I insert the Windows 7 DVD the pc says "Please press any key to boot up from CD/DVD" (as normal), but when I press the "any" key, the PC does absolutely nothing and just restarts.
Not to long ago I used the same DVD on another laptop for an equal upgrade (XP to 7) that went flawless.
My booting set-up is correct, cleaned the disc 500 times now, nothing out of the ordinairy done to my boot-screen or the BIOS... And as far as I know, no blue screen of death when installing the upgrade.
Connecting with PuTTy works fine with my public/private keys. But why does sshd start and then restart twice when booting? I tried looking in the logfiles under /var/log/ for anything with ssh/sshd but nothing shows up.
I loaded RHEL6 (first time ever loading it) and it would boot to the cmd line. I changed /etc/inittab to boot to GUI, now it freezes. I want to change it back, but do not know how to stop the boot process so I can get to the cmd line to re-edit inittab. I'm working in VMware vCenter.
Server with Centos 5.6 stop boot up for about 90 minutes. He stop: SELinux: Disabled at runtime. SELinux: Unregistering netfilter hooks audit(1307803697.466:2): selinux=0 auid=4294967295 ses=4294967295

Now Ubuntu will not complete a boot up.Studio Starts to scroll its name then screen goes back to A/numemeric reports and hangs for time-outs which never resolve.

I already have two other threads open for a dysfunctional system. Thread 1: Boot hangs at logon sound - no video signal - appears drive is still working [URL]..Thread 2: Where are boot log files and how I can see those? [URL]...Basically both of those are for not able to complete the boot (hanging up in the middle of booting) in Karmic. I had Karmic since it came out but suddenly about two weeks ago just stopped booting. Except for the battery and resetting BIOS, I had checked all the hardware - and all appear to be okay. Following a tip from x1a4, I started looking into logs (admittedly not knowing exactly what I am looking for) and I ran into auth.log. Following is the code. The highlighted part is confusing (to me) and I am wondering if this may cause to stop booting (or completing the boot process) since I was using auto logon. I do not know if there is anything else (logs) you may need, please advise and I will provide those.
I have a Debian Etch machine that was given to me but when it boots up it executes a program that is located on my desktop.
I don't want to move or rename the program but would like to prevent it from starting when the machine starts. Anyone have any idea as to what file I need to edit in order to achieve this?
I have debian/sid on my new hp/Compaq Presario CQ62 laptop. I installed usplash and started getting booting issues every fourth or 5th boot. The system stops responding till I power off the system by pressing the power switch. I checked the syslog and noticed that it also stopped without logging the cause.
By the way, except the above issue, every thing works great on my laptop with debian/sid including the wireless using the native linux driver which I obtained from hp website.
My computer is set up as a dual boot into windows 7 and ubuntu, but since I installed the latest updates, every time hit enter to boot into ubuntu the computer just restarts. It doesn't even go into the ubuntu grub loader like it usually does
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.
I'm currently using ubuntu desktop 9.10 (without desktop - I've removed packages) as OS on my server.But there's going on some strange thing ... There are about 8 users, and the thing is they many times user rar or some other disk-demanding programs. What I've noticed is that sometimes server will go with load over 20 (I know that's not good ...) and it will come down in few minutes and everything is OK, but sometimes it just restarts itself. I would like to disable that so it won't restart
When I suspend my system everything goes well but when I restart it boots up again and start from the beginning...and I don't have my programs open then...
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.
whenever I use the files, which are mostly audio files (that is, I play them), after they are downloaded, the torrent files restarts again. So I have to wait for the file again to finish downloading so I can seed.
my X server restarts and boots me to the log screen when I start programs. I recently took the Nvidia card out of my computer and put in an ATI card. This is of course after uninstalling the Nvidia drivers through the restricted drivers interface. This worked out very well but eventually I went back to Nvidia. I removed the ATI drivers put in the Nvidia card and installed/selected the Nvidia drivers just as I did when I did this the other way previously. However now when I start just about any program the entire X server boots me back to the login screen.
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:
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.
My dads' hard drive went up a while back. So we got him a new one and installed Ubuntu 9.10 instead of windows. All was going well until About two weeks ago. The system restarts randomly. Not when anyone is doing anything in particular. Sometimes when we are using firefox, sometimes just sitting on the desktop, and never after any certain amount of time.Some times its after five minutes, some times after several hours. It's not a full out crash, the window for shutdown/switch user/restart comes up out of nowhere. When we close the window, it shows back up pretty quickly, but then the computer will just crash. While restarting, half of the time the computer won't make it past the bios screen before restarting again,and will continue the bios restarting cycle until the computer is unplugged. By the way, the system is a dell dimension E310 from 2005 with all of the original hardware minus hard drive inside, so if it is a hardware issue that wouldn't surprise me. Also, just one time after the restart I received the message "fsck from util-linux-ng 2.16" , if that helps at all.
Recently, I updated the kernel to the latest version and also installed Ruby and the Passenger module for Apache. The server was fine for a few days.However, today, it's been restarting randomly (usually a minute after I can log in).I tried booting with recover mode so I could view the logs for a longer period of time, but that caused it to restart before even allowing me to log in. Now, all boot modes will just cause the server to restart right after the GRUB messages appear.Our server setup complicates things. We have a RAID-1 mirroring for the /boot partition and a RAID-5 (software) for the / partition
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 had perfectly working lucid on my laptop (64 bit) which I installed from a live CD not wubi. I tried to upgrade with update-manager and everythingooked fine until I accidentally updated compiz from the cache before everything else finished. this made compiz stop working completely, which also broke metacity. I tried to fix this with multiple things: Downgrading compiz (failed to apply changes), sudo apt-get install -f, finishing the upgrade (see the following).
during the applying changes stage of the upgrade i got an error with almost every package it tried to apply (sorry I don't know what, but it said something about 'this package failed to upgrade and may be left in a broken state'. I let the upgrade finished and at the end it said 'Upgrade Finished but not all changes were successfully applied' and I shut down the computer. when I turned it back on everything looked fine until I past to the usplash screen. Then the screen went black, a bunch of error messages scrolled by too fast to read, and my system rebooted.
I tried recovery mode and another kernel choice at grub but all did basically the same thing. Windows still works as much as it usually does but I want my ubuntu back! I am OK with doing a fresh install if I can somehow recover a small amount of my data in my home folder. If you can tell me how to get into ubuntu from windows or something that would be great but I also need to know how to decrypt my home folder (I used the encrypting option in the installer)
I can chose Shutdown from the menu but the system gets to the point where the power supply should 'click' and shut off. It doesn't, it cycles and the system reboots. It wasn't doing this in 10.04, at least not towards the end prior to updating to 10.10 beta/rc/final. Also, 10.10 didn't do this either, until recently. (Current default = 2.6.35-22-generic)
Here's the funny thing though; if I choose a previous version from the GRUB2 menu, 2.6.32-21-generic for example, the login screen won't allow mouse nor keyboard control but will shut down normally w/ a single, momentary push of the Power Button. Now, there are folks w/ a seemingly similar problem, but in their case they can't shutdown at all. My trouble is a shutdown just triggers a restart.
since the launch of Natty I have been having stupid reboots randomly happening, no warning or otherwise occurs just a full reboot. This only seems to happen when browsing (FF or Chrome) and I have disabled every one of my addons and done the usual checks - baffled I am...So I had this with the upgrade I did on launch day, so naturally I did a full wipe and fresh install. Same situation - personally I cannot deal with this happening all the time so I went back with another full wipe to Maverick and all has been well.
Anyway I thought leaving this a few weeks would mean the community would have seen and squashed dealbreaker bugs so I re-installed yesterday, today the crashes came back again so I throw myself to your wisdom - anyone else seen this, know where I should be looking for ideas? My logfiles don't show anything prior to the reboot as an error.In all honesty I do not want to go back to maverick and cannot believe that Ubuntu have released such a bug riddled distro.
I`m using Ubuntu Server 10.10. The system randomly restarts each day.Here are the logs: http://paste2.org/p/1499309Everything seems normal except that UDP: short packet thingy but even Google didn`t help me to find what`s thatBy the way, I think reboots started after I configured this PC as a gateway between internet and my local network
Where a CentOS 5.3 installation on a server randomly restarts. The problem is that I am not able to find a viable solution. I have updated the system to the latest available kernel, but to no avail...
The output I see in /var/log/messages when the restart occurs is very similar everytime:
