Ubuntu :: PC Reboots On OS Selection At Boot?
Dec 1, 2010
Everything was going great earlier today when suddenly, my PC on a fresh boot, gave me a message that said something like "Ubuntu is running on low graphics mode ..". It was running a low res, i think it was 640x480, and gave me some repair options like a. Boot in low res mode for just one session b. Trouble shoot this error etc..There were 3 more options but i don't remember what they were.
i chose "boot in low res just for this one session", but it gave me the same error the next boot. Then i tried troubleshooting, which didn't work (restoring to a backup config was no use). Then finally i rebooted and started Ubuntu in Recovery mode, and i did something like "Fix broken packages" because , from the list of options it seemed like the only one which would help at that time.
But now, whenever i choose the Ubuntu option after starting my PC, it just restarts my computer. My other OS is Windows 7 which boots just fine. Hope someone can help me with this . In the meanwhile i'll try making a new MBR or something.

How can I change the behavior of the selection buffer or a program that uses it ( I have xclip) to not send me text until the mouse button is released while clicking and dragging? This causes havok in the software I'm developing that tries to make use of the selection buffer. I need the full selection, not bits more bits more bits and then the full selection.EDIT: I cannot listen for mouse events such as button release outside of the GUI of my program.

Since I know there's a lot of support threads going, I wouldn't ask unless I was really stumped and couldn't google. I'll get right to it.
10.04 fresh installed fine, working, few reboots, all good. Installed Nvidia 195 drivers. Not so good, still works fine, but framerates not as good as the 190 drivers I'd been using with karmic. So I installed nvidia-glx-190 and nvidia-190-modaliases with the nvidia PPA for jaunty. They didn't appear on the restricted drivers list, I rebooted in the hope they would, and now my boot process is as follows.
Boot, met with a blinking _
Goes blank
Another blinking _
Green static appears momentarily, then very fast the Ubuntu splash appears, the white orbs all turn orange, and there it hangs. The splash itself is in the wrong resolution.
Everything is the same as when it was working except it didn't totally freeze at the end. It responds to nothing except the power button (and sometimes not), I can't access a shell or the grub menu at any stage during the boot process like I usually would, and nothing in the boot log seems out of the ordinary.
What should I do? I'm on a LiveCD desktop, got the harddrive mounted.
Macbook pro 4,1, 2GB ram, Core2duo with Nvidia Geforce 8600GT

I have been trying for a couple days now to install 10.04 on a 250G hard drive that was a USB boot with 9.1. I want the hard drive in the case. The bios has been changed and does see the new drive. Boot selection has been changed to CD Rom. Everything starts out fine until step 4 of the install, Prepare partitions. There is no hard drive available on this step. The HDD is not seen by the disk utility either.

I have a Toshiba F30-114 laptop on which I want to have a dual boot Windows XP/xubuntu configuration.The problem is that when I install Xubuntu as dual boot, Windows XP gives a blue screen of death for a second and then reboots in the begining of the windows boot sequence.I can choose Safe Mode, Safe Mode With Networking, Safe Mode With Command Prompt, Boot With Last Good Configuration, and Start Windows Normally. But nomatter which one I choose it will result in a bsod following a reboot.I tried to remove the Xubuntu partition, which somehow also resulted in removing the XP installation. I then put the harddrive in an external case and used EASEUS Partition Recovery 5.0.1 on another machine which got back the Windows partition. Now Windows works again without any bsod.

I have a Ubuntu - windows 7 dual boot (in two partitions of the same HDD) desktop PC for a few months. I was learning terminal commands and, although I don't think I made such a big mistake, but the fact is that the a very strange thing happenned: "Preferences" and "Administration" from System disappeared as it did also "Applications". After rebooting the same it remained the same. No big deal, I thought, because I haven't yet saved any important work on Ubuntu. So I reinstalled Ubuntu. Done that everything was nice until I booted Windows... Since then I counldn't start windows after GRUB due to:
Status: 0xc000000f
Info: The boot selection failed because a required device is inaccessible."
Windows Live DVD Repair is useless. I've tried CHKDSK utilities, no result. Windows partition in Ubuntu's Disk Utility is OK but I can't access the files (all "broken links"), just can explore a few directories after which I find myself entering the same folder endlessly. I wanted to repair windows boot or at least recover some important files in Documents and I thought I had backup (but turns out that, for some reason that I'm still trying to understand, they aren't...).

I locked the screen, came back, typed the password, screen remained black, though cursor was visible and moving. Nothing I could do to rejuvenate the screen. Had to switch to tty6, sudo shutdown -r now. Then, on reboot obtained kernel selection, it proceeded to displaying kernel messages, but froze on sdb, after 3 secs. I figured it was the usb, so turned off, removed usb cables to external hard drives, but again it froze saying something about firewire mouse, the mouse is also usb. I tried several times, but no matter what kernel I chose, I couldn't get it to boot. So I loaded puppy live cd, but now it can't access some parts of the disk. I was running utorrent and the folder with partially downloaded files can be accessed but there's nothing there (there was), and some folders can't be accessed at all.

I have several RHEL 5.0 servers in a secure network. We have identified around 200 rpms from 5.4 that we would like to upgrade. These servers have no connection to the internet, and very limited connection to the corporate network.
The application guys will not approve a full 5.4 upgrade as the app is reliant on certain rpms from 5.0.
So how can I create a boot disk that will install just the selected 200 rpm's. I have been trying to modify (remove rpms) from the downloaded 5.4 dvd, but with no luck. I have also had a look at anaconda, but seem to be going round in circles.

I just attempted to install ubuntu for the 4th and 5th time and have yet again had a fail. This time it actually completed the installation, which is a first. however upon reboot it takes me directly to Vista - I don't see grub or a o/s selection choice.

Ubuntu 10.04 I am dual-booting along with Windows. I need to change the order of boot options so that Windows is the automatic selection rather than Ubuntu. I cannot find the file to make the change and not sure what changes I should make when I do find it .

I just installed 5.6 using the x86_64 netinstall - all appeared to go well, albeit a little slowly. At the end of the install i rebooted the machine but CentOS won't load. If I select the CentOS option from grub (only other option is 'other') the machine instantly reboots.
Only options selected for install where 'server' and 'server gui'.
Editing the CentOS options shows the following but I've no idea whether this is correct or not (assume it is):
root (hd1,0)
kernel /vmlinuz-2.6.18-238.e15 ro root=/dev/VolGroup00/LogVol00 rhgb initrd /initrd-2.6.18-238.e15.img

I have a 10.10 machine where it has taken to refusing to logout of one specific user account. When I choose logout/restart/whatever from the possible options, it takes me to the main login screen (with the drums) and it shows thet that user is still logged in. The only way, once this occurs, to rid myself of this is to sign in as an administrator and run shutdown -r 00 under sudo. Then it reboots. (Using the admin account to choose restart/shutdown also returns me to the mail login screen where that unpriv'd user is still logged in.) (The machine is fully up to date.)

I'm having an issue with a PC ( Gateway GT5220 ), with Ubuntu 64 bit 8.04 installed. There was Vista originally installed in it.
Now, every time I execute shutdown from GUI or command line, the PC reboots and never shuts down on its own, I have to keep pressed the power button for a few secs to power it off. It's very irritating and I don't know wether it's a Ubuntu or a BIOS issue.

24" intel iMac , 4gb ram, fully updated.
I have installed amd64bit 10.04 for some reason the system will reboot without warning. I can not see any issues that point to any major problems in the logs.
All hardware appears to be working well although i have not yet tested the built in web cam.
Are there any extra debug log settings i can switch on to try and track down whats causing the reboot.

Prior to this version of ubuntu my laptop (an old P4 gateway) shut down just fine. It acted fine in windows xp, and ubuntu 9.04, 9.10, and 10.04. Starting with my first shutdown after upgrading to maverick (as opposed to a fresh install, which is what I've done for every time I went to the new version before this), it just reboots the computer instead of shutting down.I've tried clicking the icon in the corner, I've tried pushing the power button and clicking shutdown on that screen, I've even tried shutting down from the command prompt, but each of these just reboots the computer.

I am trying to write a script to add to crontab that I can use to auto update my system a couple times a week.I've done that much before, but I want to make the script a bit smarter about rebooting. Before I had it reboot after running the "apt-get upgrade" command, regardless of whether it needed to or not. Easy peesy stuff, just a sequential command using "&&".What I would like to know at this point is how I can have the script look to see if the reboot is even necessary. I am assuming there is something I can tell the script to look for in an if statement, but I'm not sure what or where. Can anyone point me in the right direction for this?

I downloaded and installed Ubuntu desktop on 9/26/10. Not sure what version that would be but that is my download date. Running a dual boot XP 32bit/Ubuntu 64bitNo problems at all so far and I've been keeping up with updates manager. Two days ago I went start my machine and chose Ubuntu from the OS selection screen as usual. The only thing that shows up on the next screen (grub menu I believe?) is "HD (0,0) NTFS5" for about 1.5 sec and then reboots.
Windows boots and runs fine. They are both installed on the same physical drive. Not sure what else to search for or include for information. I've tried searching the forums but not sure what nomenclature to use.Trying to avoid reinstalling. p.s. I knew I was enjoying Ubuntu but didn't realize how much until I was forced back to using just XP.

I installed Ubuntu 10.10 on my computer from a USB. I did not use wubi to install ubuntu. The computer already had Windows 7 installed. According to gparted, Windows 7 is installed in sda1, linux swap space is in sda2. Then sda3 is shown as a drop down menu containing sda5, where linux is installed. A picture to show this is attached . sda4 is a recovery partition that came with the computer.
The problem is that Windows 7 sometimes boots, and sometimes it does not boot. Most of the times it does not. Ubuntu boots perfectly. The process to boot is the usual, turning on the computer, wait for grub to load. If I pick Windows, it goes to the splash screen (which is by the way not the usual windows 7 splash screen, it resembles more the vista splash screen, picture attached. I do not know the reason, and I have no idea if it has anything to do with the problem) About 80% of the time, it simply reboots a few seconds after the windows splash screen is shown. The reboot takes me back to the usual HP splash screen, then grub again. The other 20% of the time, it boots normally and works perfectly well.
Right after I installed ubuntu Windows was shown in grub as installed at sdb1. I updated grub and now it is shown as sda1. I already tried some grub custom entries for loading Windows differently, but they all present the same problem. Please do not discard a custom entry as a solution, as the source I used for these custom entries was not entirely trustable.
I also tried popping in the windows installation disk and trying a system repair, but apparently no errors were found.
Reinstalling grub using Ubuntu live cd (booted from a USB) did not work either...

i just bought a new computer today and Ubuntu 11.04 reboots whenever i try to shut it down. Most of the time it just hangs there. I've tried to ALT+CTRL+F2 and shut down with the terminal there by "sudo poweroff" but the system freezes and hangs at that screen, not allowing me to see what's going on. If i leave it for 5 minutes or so in that state, it'll reboot. I've also tried Lubuntu, Kubuntu and Xubuntu and they all have the same issue. I've tried their latest versions.
I've searched endlessly, i've messed with the BIOS settings and nothing. I've added "acpi=off" and "acpi=forced" and neither worked. The only way i can shut down my computer is by holding the physical power button.The computer is an HP P6710F. AMD Athlon II 640 x4 processor. ATI Radeon HD 4200 graphics card. 4GB of memory. 1TB of HDD space.

I've been trying to get Ubuntu on my computer for months now and after having googled no relevant cases which may help me I would like some help.
I am trying to install Ubuntu on my computer (which already has windows and I don't want to lose it yet)
I have already burnt 3 CDs yet the problem is the same each time, that's why I believe the problem does not come from the burning. I checked the md5sum and there was no problem.
However when I try to install Ubuntu (or sometimes during a live session) after partitionning my computer and selecting mounting points, having "format" checked on the concerned partitions, the installation goes halfway through the "copying files" process and my computer simply reboots. More precisely, in the middle of installation the screen is replaced with the loading page of Ubuntu (like when you start with the live CD) then my computer reboots, no questions asked (not even to remove the CD, it reboots with the CD in it... while during a manual shutdown it would open the tray and ask you to close it)

I keep having issues at the main password screen. The computer starts, I click my login name, type password, start to hear the music, screen distorted, then reboot. Sometimes I have to do this up to 20 times before it finally logs in.
I am running a Biostar U8668-D Motherboard with 1gb ram. Video is onboard. I am not sure what type. I think it may be S3 Pro Savage.

This happened with 09.something and again with 10.04. When I plug in my Palm Centro smartphone, it starts endless rebooting. I solved it last time by removing modem-manager from /usr/bin.But that program didn't reappear through my upgrade.
Well, when I first upgraded, then plugged in my Palm through a USB cable, the phone rebooted. Then, I was able to sync to JPilot. Attempting the same thing later, the phone rebooted continuously.Today, I seem to be able to sync again.
