Ubuntu :: Computer Won't Boot / Fix It?
Feb 4, 2011
Alright, so one day I was on Windows 7 and I install some hardware called "Flux" and then I get IRQL NOT LESS OR EQUAL bluescreened.. GAY. Luckily I had dual-booted with Ubuntu 10.10 ^__^.. So one day I was on Ubuntu and I was thinking of doing a system recovery for Windows 7. As I was backing up my files something went wrong I guess and then I went to my disk utility thing. I then found my main hard drive and decided to mess around with it(Because I'm Stupid) Now I accidently unmounted it or something. Then my Computer shuts down and comes back up saying "No Bootable Devices"... I then went on to run hp tests and found out my computer knows the HDD is there but its not detecting it as a bootable device UGH. So how would you suggest I fix this? I was thinking of putting bootfiles on a blank dvd and making ubuntu boot from my dvdrom. But what would happen to my old files? I really want to keep my old files. -__- Do you guys know how I can fix this?

I've been a long time Windows user, but I've started a small firm and because of lack of funds, I've decided to install Ubuntu on my company's PCs.I have 8 PCs in total - 6 of them with Intel CPUs, and the last two with AMD CPUs. I bought the extra two computers because I've managed to find an extra two people to work at my company, and AMD-based PCs are cheaper so I've decided to buy them instead of Intel.Long-story short, I've installed Ubuntu 9.10 and boot time takes about half-an-hour. After the computers finally boot, USB hardware doesn't work at all. I was forced to buy PS/2 keyboards & mice and they both work fine after the PCs boot.I don't know what's causing this delay.I've enabled Cool 'n Quiet from BIOS.I've tried several instructions like editing the /etc/modules file.I've installed cpufreqd, tried to configure it, but it didn't work.I've check the CPU stats and my CPUs are running at 800MHz. I can't believe nobody managed to fix the 800MHz problem as I've noticed it's quite common among AMD Ubuntu users. I think I've tried almost anything that I've found on this forum.I can't keep asking my employees not to reboot their PCs. Both Chrome/Firefox crash a lot on Ubuntu so they're forced to restart their computers.The computer specs are: AMD Athlon II X2 240 dual-core @ 2.800MHz, 2GB RAM, 500GB HDD, etc.

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.

it started with rooting my Motorola Droid. I got quite interested in the whole rooting/linux "world". The only problem is, my hands move A LOT faster than my brain does. I'm an "educated novice" at best when it comes to all of this and still learning slowly, but surely. I followed an online tutorial and before I realized quite what i'd done, I had dual installed Ubuntu linux 10.10 on my laptop. ISO'd this, partitioned that and realized....i'm in way over my head. Then I started researching how to just go back in time and get my "safe" windows vista back until I'm ready to make the switch to linux and just ended up getting more confused.
How do I actually BOOT into Windows on a dual boot computer that I apparently just created? How, if need be, do I undo everything I just did in the past few hours and careless tinkering? If I decide to stay with Linux, how do I get my damn wireless router to recognize?

i have downgraded from Ubuntu 10.10 to Ubuntu 10.04. I've had some bumps along the way and finally was able to install 10.04 successfully. Right now, my computer will not boot from the HDD and will only boot from the USB drive that the LiveCD is on. When I reorganize to set HDD as primary boot, i get:id-laptop login:d-laptop password:and I can put that in but then it just gives me a command line that ends with ~$ i believe. How do I get it to boot from the HDD instead of from the USB without running into this problem?
If I resequence the boot to HDD as number two, it will juts go into the LiveCD mode. Am I supposed to reinstall 10.04 again? I know 10.04 was successfully installed because it said it was and it needed to restart so i hit the restart button. It also had my old desktop picture there and all my files AND i checked the system info before restarting (it confirmed that lucid lynx was running).

I have (had) a dual boot computer;Win XP and Ubuntu 10.10 64 bit.I decided it was necessary to enlarge my Root and Home Partitions. Using the instructions http://ubuntuforums.org/showthread.p...ome+Partitions I successfully enlarged the partitions and restored 10.10 (I used the copy command suggested by Irony). However when I boot the computer it boots to Ubuntu but no longer gives me the option of going into XP(it is not listed in Grub menu). Is there a fairly straightforward way of getting XP back on the Grub menu so I can boot to XP again?

I have been having a problem with my 11.1 recently, in that it gets stuck at a point in the boot process that tells me "INIT cannot execute /bin/sh" then it says "INIT: id 1 is respawning too fast please wait 5 minutes" and tells me there are no more preocesses in this runlevel and repeats this no matter how long I wait. Since I couldnt find any information on fixing that, I decided to just upgrade to 11.3 with a boot disc. Now my computer wont recognize the disc to boot from it and still gets stuck at the same screen.

The Ubuntu installer think my /boot partition is (hd0,0). This is what it writes into grub menu.lst. My computer won't boot after install completes. The Ubuntu live CD shows this boot partition is (hd4,0) (sde1). But that doesn't work and after editing grub menu.lst to (hd4,0), the computer still won't boot. Some searching at the grub command line show the correct value is actually (hd1,0).

My computer was built by a small, local business. This past spring, I wiped the computer and reinstalled Windows 7 Pro from a 64 disk. It has worked well. I wanted to play with Ubuntu, so I set up a dual-boot. When I first installed Ubuntu last week, I had issues with Java. After countless failures from Google, I installed a new Ubuntu partition without deleting the old one. The other day, I got curious and wanted to try Mint. This went on yet another partition. Yesterday I wanted to organize this out better, so I formatted the Mint partition and it's swap. The computer functioned just fine until I tried to reboot. It starts out with normal BIOS(?) stuff, "Loading Operating System..." for a bit... and then breaks. It says something about not being able to find device, shows a UUID, then goes into grub rescue.
I spent around an hour or so Googling about this and have come up with nothing. Internet tells me to do this, I do, nothing happens. Internet tells me to do that, the file does not exist, nothing happens. I was Googling via my mom's laptop, and I am currently posting this from Firefox on the LiveCD (demo). I still have my Windows 7 install disk, although finding it is a different story.
How do I fix my booting issue, preferably without losing any data from my second Ubuntu install (I do not care about the first one - on sdb5?) or Windows 7.
sudo fdisk -l
Code:
ubuntu@ubuntu:~$ sudo fdisk -l
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

Brand new build, top of the line components, windows 7 x64 installed and working flawlessly. I've got the boot order with cd rom first, usb 2nd, hard drive 3rd. I've got a good DVD in the blu ray drive, and it does not boot from the drive. Also same issue when the USB is in. Its using a SSD and I almost get the impression its checking things too fast then just heading to the SSD to load windows. Any ideas?
I've put the DVD into a crappy old laptop I have and it boots from it so I know its functional (the laptop shows some error for kernel or something but regardless it does get the ball rolling).

Installed 11.04 several ways on ACER AMD 64-bit Phenom II computer with Win 7, 1.5 TB HD, and 500 GB Sata removable but none would boot. LiveCD works fine with Unity desktop displayed. Installed first using Wubi but would not boot. Then installed in 500 GB USB removable allowing entire disk to be used. Installation completed OK but would not boot. Created Super Grub2 disk and booted to it. It recognized Grub.cfg in removable but just got a black screen with blinking cursor in top lefthand corner when tried to boot Ubuntu. Then I cloned this installation to the primary 1.5 TB HD in an ext4 logical partition. It was recognized by Super Grub2 but would not boot. I tried a fresh installation from the LiveCD with the removable turned off, hoping that the new ext4 partition would be seen, but such was not the case. All I got was the message (during installation attempt), "No root file system is defined". I used the AMD64 version of 11.04 since the computer was 64-bit.

I know these forums are not about Windows, but I think I'll get better help here than in one of the Windows forums, let me explain, why:A friend of mine has a computer with Windows 7 on it, now it just doesn't boot anymore. I already changed the boot sequence to CD/DVD, but even with the recovery disc, there is nothing happening at all.Now, since I use Ubuntu 11.04 personally, I thought 'why not try Ubuntu Live'. There's this one second where the purple screen came up (this only happened once), then it's black again and then, 3 minutes later, this is what comes up:
Code:
udevadm settle - timeout of 180 seconds reached, the event queue contains:
/sys/devices/pci0000:00/0000:00:01.0/0.0000:01:05.0 (933)
[code]....

I have Ubuntu 9.10 64-Bit. sometimes when i boot the computer, right after the grub loads, a black screen is displayed. It just says my computer's name and "tty1".It lets me enter my username and password. The system takes my password but the black screen remains.For some reason the word "ubuntu" with the loading bar does not appear like it is supposed to in this case. The system does not boot into my destop like it should.
This usually happens 1/4 times when i boot so i didnt pay much attention and would just restart the computer. However just 5 minutes ago i had to boot my computer 12 times to get it to boot into the desktop.

I work in a retail store at which there is a computer set up in the corner for customers to browse the stores website on. The problem is that that is all it will let me do. I get board, and want to do other stuff. Once windows starts, it skips the logon on screen and once loaded the only thing that can be done on the computer is browse the stores website.
However, if I unplug the computer I can while its starting up get into BIOS. So here im wondering two things. 1) If I put in the USB, boot from it, and load ubuntu (even though I will only be able to use the default programs as theres no way I would want to install it on the work computer), will I get fired? In other words, is there a way if there monitoring the computers to know what im doing or because its a different OS will I be fine. 2) Alternatively, in BIOS there is an option to disable network administration.
For this my question is the same, if I disable it, do fun stuff on the computer all day, the re-enable it before I leave is there a high change of the network administration catching on to this or no.

I'm currently running ubuntu 9.04 32 bits which I installed with my usb stick. Now the problem is when I try to boot Windows 7 from usb drive it won't boot. Have checked bios that removeable dev is prio 1 and I even tried to delete any other option then boot from usb.
Tried the usb stick on my HP desktop and it booted from the usb stick without any problems. I have an ATI motherboard and i'm quite new in linux so can't realy provide any information about the motherboard but I'll show a pic. Don't know what i'm doing wrong since I can boot another computer with the usb stick.[URL]..

I recently changed my computer so it would auto boot into Ubuntu, but if I hold down the shift key, I can bring up the GRUB menu so I can choose Windows in the rare times I use it[URL]Anyway, I noticed that when I did that, it actually took longer to boot. I timed it today and it took 45 seconds from the time I pressed the power button to get to the login screen! My friend uses Linux a lot and says even with Ubuntu (which he thinks is "too slow") it shouldn't take that long.

So I run a dual-boot win7/ubuntu system and out of nowhere I am now unable to boot into ubuntu. I get up to the screen where I select which OS to boot into, then I select ubuntu, get the wubldr messages and then my computer instantly resets back to the original load screen.
This comes paired with a bad boot into my windows partition so I feel like they may be related. I did a system repair and now windows works though. I'm defraging my harddrive now just to see if it works.

I've been using Ubuntu Netbook edition on my Asus eee pc 1005HA, dual-booting with Windows 7.Things have been fine with it for a month or two. However, I've now run into some trouble with Grub2 and the MBR, and I cannot get my computer to boot into ANY operating system. Right now I'm booting from the Ubuntu installation CD to "try Ubuntu" -- it's the only way I can use my computer at all.
I have looked through the forums and googled, and already tried several methods of fixing Grub2, none of which have worked so far. Here's the situation: I wanted to disable / uninstall Grub2, so that the computer would boot as normal into Windows 7, to fix some problems and then reinstall Grub2 later. To do this I just went to the Windows System Repair environment, opened the command prompt, and entered the two commands "bootrec /fixmbr" and "bootrec /fixboot" with the understanding that this would reset the Windows control of booting, and remove Grub2's control. The result was that my computer cannot boot properly at all. No Windows and no Grub2.
So far I've tried to fix this by using the Super Grub Disk to try to use the auto-repair feature, which failed. I've also tried in various ways to reinstall / repair / update Grub by using the Terminal in Ubuntu (through the "try Ubuntu" CD), but so far none of the methods I've found have worked. If anyone could explain or direct me to a step-by-step of how to repair the MBR and install Grub2 from scratch,

I'm very new to Ubuntu and installed it (10.10) just a few days ago on a laptop I got for my girlfriend. The problem is that she wanted me to change the username and computer name that I have set up when installing, which I tried to do. I followed the instructions on this link to change the computer name/hostname: [URL]. Obviously I did something terribly wrong, because after trying to restart my computer I couldn't boot it. It freezes immediately after the BIOS screen - just displays a blinking dash in the top left corner. The same thing happens when i try to boot from a CD (I tried both Ubuntu and Windows 7 CD's. Resetting BIOS to default also did nothing.
