Ubuntu :: System Halts And Now Computer Not Booting
Sep 9, 2010
Yesterday I was working on my laptop using the windows 7 partition. At some point it froze and I ended up just having to shutting it down by holding in the power button. When I started it up, it said something along the lines of "can't find bootable partition".
So I made myself a ubuntu flash-drive, and ran
Code:
sudo fdisk -l
This is my output.
Code:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x74836e35 .....

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.

Just installed Ubuntu 9.04 last night. All seems perfect except on shutddown. It seems to go through all shutdown processes but right about the time you expect the computer to turn off a message says: "system halted [4027.514883]" Have Googled it but no matches. If I just push the on/off button at that point it shuts off immediately

I have installed ubuntu 10.10 for a short time, now I meet a problem:I always leave for lunch and leave my computer without turning off. When I get back, it shows a window. after I input my password, I enter my system.Then It halts, the only thing what I can do is moving mouse. After halting for nearly one minute, it resumes to normal.I hope someone can tell me what happens.

I am trying to start Damn Small Linux from a USB stick on a HP t5000 thin client. When starting in Default mode the system just stops. When starting i failsafe mode, the text rolls on the console until the message "RAMDISK: Compressed image found on block 0" and then hangs..What does that mean? What could be wrong? Can I run the image without using a ramdisk?

The situation: computer based on Asus P6T motherboard. Two RAIDS:
- 'boot', on motherboard built-in RAID controller (CentOS 5.5 installed on this RAID)
- 'data' on 3dware RAID card
At one moment a CPU fan fails and the system halts. After the fan is replaced, BIOS informs it's reset and all the inner controller data are forgotten. After I switch it to 'RAID' mode, it remembers it was a mirror raid (RAID 1) installed, but the file system on it is completely trashed.
The 'data' RAID run by external controller isn't affected by the system failure. Three questions:
- is it worth trying to install OS on the rebuilt 'boot' RAID once again? Looks like if BIOS settings are lost for some reason, there's chance of completely losing RAID data
- has someone encountered similar problem with built-in RAID nd was it possible to recover data?
- will the software RAID be worth creating instead of using hardware RAID to replace the 'boot' drive?

I just found couple of tutorials to help me boot Ubuntu using a USB on an old computer. This is exciting! Basically it works like this: Download a program and burn it as an ISO, and it allows you to insert your USB stick, and boot ubuntu (or other OS).
Anyone ever tried this? Because I am about to try it and I have some questions.
Once I download ubuntu, do I have to use use a tool such as UNetbootin to make it bootable, Or I just extract the contents of the ISO? btw here are the tutorials 1 and 2

I'm trying to install Ubuntu 9.10 on an old computer. Basic stats are a 350 MHz Pentium II, 768 MB RAM, and an ATI Rage IIc--not sure how much video memory at the moment. I managed to install XP on it at one point, but decided not to let it stay a Windows box.The computer won't boot from the Ubuntu 9.10 CD, nor the alternate install CD. It gets as far as displaying:ISOLINUX 3.63 Debian-2008-07-15 Copyright (c) 1994-2008 H. Peter Anvinbut the never does anything else. Anybody have some ideas about what is happening or what I can try or do differently?

I recently installed Ubuntu on my computer, and today after hooking up the internet for the first time it asked me to update. I clicked install, then restarted the computer.
While booting up it hangs up after the following is displayed:
fsck from util-linux-ng 2.16
/dev/sda1: clean, 149460/2400256 files, 984175/9582764 blocks
I've tried ctrl-alt-delete, it restarts, asks me how I want to reboot, and whether I choose generic or recovery mode it still hangs up here. What can I do to be able to access my computer again.

I have an old dell laptop that I want to put ubuntu on but it doesn't have a cd drive, I can't boot from a network, and the bios doesn't support a usbdrive. It does have a floppy drive and I wanted to know if there is a bootfloppy that allows me to boot from a usb?

I've been using Ubuntu for about one year. Recently upgraded to 10.04. The PC tries to boot, comes to the "Booting from device hd..." screen and then shuts down. It shuts down or halts but doesn't power off. The CPU is still powered. This happens for about 2 in 4 boots. The recovery mode runs just fine. It says no damaged partitions. Only the 'booting from device' is the problem point.

So, first of all, this is my sisters computer so I am not sure exactly what happened. I had installed ubuntu alongside WinXp a couple of weeks ago. Today she booted into xp for the first time and accidentally launched some system restore option. A dialog box appeared and told that if she continued, everything on her disk would be erased. apparently, there was no indication of how to not to continue, so she shut it down by holding the power button.
Now, it won't boot. Not even to grub, it just cycles where the screen comes on, a courser blinks in the top left, and then it automatically restarts after about 5 seconds and repeats (unless one launches BIOS configuration). I assume something about the MBR has gotten messed up. I tried booting off a USB thumb drive, but it just accessed the drive for a second or two, and then went back into the cycle (I tried every USB socket, and the BIOS was configured properly to boot off external USB, also, I was able to boot my computer from the USB)
how to proceed if I can't even boot off of USB. Oh, the computer is Asus Eee pc netbook (no CD drive).

I am attempting to install Ubuntu Netbook Remix (I even tried Ubuntu Desktop) off of a USB drive. I use unetbootbin to prep the drive, my BIOS is configured to boot off the USB Hard Drive, after booting up the computer I get a message that reads "BOOTMGR is missing, Press Ctrl+Alt+Del to restart" This laptop is currently running Windows 7 which, after removing the USB Drive, boots up fine.
I've seen other posts on this but they all refer to dual-booting and modifying grub configuration files. I'm not even to that point yet (and don't even want to dual boot, to be honest) - I'm just trying to get onto the "LiveCD" so I can format and install.

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.

My distribution upgrade got interrupted in a hard way and when I start the computer I get some errors:
Code:
kernel panic - not syncing: VFS: unable to mount root on block 0, 0
or sth like this and a few more errors. Can't look the exact message as I am writing from the liveCD. On Gparted the boot looks normal and it is said that it's mounted but there is no mount point. There are things on the hard drive that I must save.

UPDATE2: As of 2 weeks ago, it won't boot at all. UPDATE1: HDD booted OK, but I don't know how to copy the GRUB file. Could this be a hardware temperature problem? I have just replaced a Hard Drive, & had to reinstall XP & 10.04.2LTS from scratch, (it was a TOTAL failure) The system now will not boot into XP, or either of the 2 Linux kernels or the recovery modes, without several attempts. ( I'm using a LiveCD now.)
POST is good. GRUB loads, but when I select an OS, it powers off. Windows shows the splash for a few seconds, then shuts down. Yesterday, I was able to boot into Linux after booting into Windows, but today Windows won't boot either. On examining the GRUB menu (e) the first line in the Linux records is 'recordfail' I will attempt to boot from HDD now, & post the GRUB output here. EDIT: If I run MEMTEST first, up to Test6, it boots normally.

several months ago I installed Maverick and it worked well, but eventually I lost the GUI. I fiddled with it to no avail. So I decided to do the Natty upgrade and it ended up not fixing the problem though I am able to boot to graphics safe mode.
I popped on this forum and a couple others but got little response and ran out of fiddle time. SO now I have a little time to mess with this, and I REALLY want to move back over to Ubuntu so if any one is familiar with that could be the issue

having major trouble installing Debian.erased the data on one of the partitons that used to hold Vector Linux and tried to install Debian on but it failed for some reason.Since I'm dead tired (well, was) I thought I would call it a night and just wait until tomorrow to finish the installation.So, I rebooted my computer and all it would do is this:
99 99 99 99 99 99 99 99 99
99 99 99 99 99 99 99 99 99
It would just do two or three rows of 99's and then it would hang. Does anyone know what is happening? Right now I have Windows on this computer and I can't even boot into that. The data for Windows is safe but I just can't boot into Windows for some reason.n erasing sda6, did I accidentally erase LILO too (Vector was the first option on LILO)?If someone has posted this problem in the past

I recently install Ubuntu-studio Desktop and some other packages. And, I upgraded my System. But since then, the Grub has started to display (I have only 9.10 installed, using the entire Disk). Also, unless I select the entry, Grub does not automatically start. The startup takes nearly 1.5 minutes. And, the Login screen, after the installation of Ubuntu Studio GDM, is much slower. I removed the Ubuntu-studio GDM package, still it takes about 20 seconds to allow me to enter Username and password. Any idea?

I am a ubuntu user and I tried to install ubuntu on my sister's netbook too. The problem is that the netbook has a broadcom wi-fi n that is not supported by linux for now because I searched for drivers and other stuff an I found that it is not supported. After that I tried to format the disk and reinstall windows 7 but the problem is that the installation procedure gives me this error: "windows cannot be installed on this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enable in the computer's bios menu."
I tried to do all the things that are described here: [URL] but it's still not working.
Obviously when I format the drive with ubuntu and I put it in the netbook it's not working, it stops at the logo and the only thing I can do is entering BIOS.
I formated the drive with a windows os and then the pc makes the boot from usb but the problem persit...I still can't install because of that error :"windows cannot be installed on this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enable in the computer's bios menu."
Before installing ubuntu the sistem had kaspersky antivirus and detected 1 Trojan, it could be that a virus destroyed the bootsect...I don't think so.

I have a WinXP computer with two internal hard drives that are partitioned. I would like to setup a dualbooting system. I first attempted to install PC-BSD 8.0 from a DVD onto an external 640 GB USB hard drive. Everything looked it was going to work (including the boot loader program) until after the installation. PC-BSD took out the NTFS of the hard drive (with over 500 GB of Window files). And the bootloader never loaded on startup. It took two days to get everything back. The files created on this external hard drive could not be read by another linux operating system (Slax 6.1.1). I would like to load PC-BSD on one of my empty partitions (from my second hard drive). The manual for PC-BSD states PC-BSD has to be installed on a primary drive and not a logical drive. If you attempt a logical drive installation, PC-BSD will wipe out the entire hard drive on installation. Would it help if I format a logical partition to the linux file system and then attempt to install PC-BSD to it? I can use Slax 6.1.1 from a CD to format the logical partition.

My computer runs Karmic and has quit booting when it is plugged in. I was told it was the AMP needing updated. How do I do that? I do the updates from the update manager, does this mean I missed the AMP update or is it done differently than through the update manager.
