Ubuntu :: Unable To Boot After Hard-reset After Using Rm -r As Root / Enable It?
Apr 6, 2010
First of all, i'll just say this myself. I'm a dumbass and tried to fix somethings that wasn't even a problem from the start and now my 9.10 installation is totally fubar. There, done, now let's move on.
Ok, so I tried to delete a folder after compiling two binaries to the wrong folder and used the
Code:
rm -r
command on what I thought was the folder /home/lars/bin. And to add to the dumbass-ering, I was root while doing this. The computer hangs and leaves me with no other options than doing a hard-reset via power-button.
After rebooting I can't even see the login screen, it just hangs at the Ubuntu symbol.
So I give the recovery mode option in my grub menu a try and it gives me a bunch of lines, all looking good until I get this and the boot just stops with a blinking underscore. code...
Should I just beat myself for a while and then reinstall the OS or what...?
The hardware involved is a Asus EEEpc 1000h.
ps. I'm new to Linux and have so-far managed to get around by following guides and tips, just a heads-up.

I'm new to Linux, tried Ubuntu, had slow boot problems, tried openSUSE 11.1, still have slow boot problems. The issue seems to be that the ata.0 device is slow to respond (ERROR= -16), the boot system forces a hard reset, then a soft reset, configures for UDMA 133, says the drive is ready, then does it again, three times, and then configures the drive for UDMA 100. It's a brand new Western Digital Caviar drive, and windowsXP likes it just fine. Once SUSE boots, everything seems to work just fine. I thought the problem might be with the drive jumpers, so I reset them from cable detect to master/single. No change in the problem.

I'm unable to reset using either the reset option in gnome shell or the command using a terminal. When I select it the shell exits and displays the graphic "exploding" and then it just sits there. Shutdown works fine; just no reset. Any ideas? I've installed from the DVD. I booted the live CD and it resets just fine so I know it's no my hardware

I am working as system administrator for the past 5 years, but only on Windows XP systems, I recently moved to Linux, frankly speaking a few days ago, and i got many problems with it. may be as i am a beginner. My Problem started with Ubuntu 9.04 amd 64 and now with 10.04 beta.
The main problem I installed the wine (I am aware that wine is not compatible with all softwares of microsoft) and Installed microsoft office 2007 and it installed successfully but after installation when I launched Microsoft Excel it got hanged (only the Microsoft excel) and loading logo stood on top of all applications, then I decided to restart and pressed the restart button from menu on the right top. but there was no further response, then I pressed the reset button after waiting for 3-4 minutes to get rid of that logo of Microsoft in the center of my screen.
Now, when the Ubuntu was booting, Text arrives and disappears fast saying dev/file system has errors the logo of Ubuntu 10.04 and dots of loading at the bottom arrived and text written in the bottom of that "on of the drives needs to be checked, please wait it may take some time" Press 'C' to cancel disk check up. Now, its checking for a long time maybe for 30 minutes and the bottom text disappears and the loading Ubuntu 10.04 logo still remains and nothing happening after that.
I Pressed alt+crtl+del 2 times, it restarts saying that saving some alsa process, then again the same thing after restart. If I press C, it displays in the bottom of Ubuntu 10.04 logo "/File system has errors" and the loading screen remains like that. Now what is the solution and what are the precautions to be taken while using Ubuntu, as I was interested in introducing Ubuntu to marketing managers of offices, who wonder on the Internet all the time finding stuff and getting attacked by viruses. If this type of problems continue in Ubuntu, it will not be safer to use it, as if it wont boot during sudden power failures, that could result in a big problem.

I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?

Problem:
Error: no such device: f50139a2-b475-4ef5-8217-051bd145a24e.
grub rescue> _
I know it is saying that the harddrive that I installed ubuntu is missing.
Heres the story:
My friend's computer wouldnt let him boot to the CD to install Ubuntu on his computer.
So I put his harddrive into my computer as my 3'rd Harddrive and booted the CD on my Machiene and installed Ubuntu to his harddrive.
We got ubuntu to work just fine, and then I removed his harddrive from my computer... big mistake. I no longer have the harddrive that we installed ubuntu to so I cannot use any programs or anything.
What I want to do is get my Windows 7 working again. Right now I cannot do ANYTHING.
I have tried code...

I have a Dell Inspiron 1525 and I've been trying to boot into the live mode. I can get into the main 'Try Ubuntu without any changes' menu, but selecting that option causes the CD tray to spin up, followed by the head audibly flailing about for a minute or two causing the laptop to noticeably vibrate, followed by nothing. It doesn't boot or give any errors, it just stops. I can read the discs just fine in Windows.
So far I've tested shipit CDs of 9.10, 9.04 and 8.10. All cause the above problem. 8.04 works perfectly.

I've been dual booting 10.10(with Windows7) for about a month. Today is the first time I've encountered a serious problem.
This morning, nothing functioned properly after trying to open up several programs. The computer seemed to be "frozen", although the mouse was working fine.
I decided to reboot, but then encountered an even bigger problem. It failed to boot and got this message code...

I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.

I am able to get into GRUB and boot Linux, but whenever I select Windows, all I get is an error about a missing boot loader.
After the Windows install disk failed to repair it, I reinstalled the Windows system and then used the Ubuntu live-CD to restore GRUB in order to be able to boot into Linux again. Now I have the same problem as when I started (although the error screen is somewhat different now).
Does anyone know how to break this "evil circle" of mine?
I am using the 10.10 (GRUB 2 in other words).

I have an Eee PC 701 4G, and some time ago I disabled its wireless NIC in the BIOS to save energy. Now I've come to need it working again, but I can't re-enable it, because it always goes back to being disabled after I boot the eeebuntu installed on the machine. If I just enable it in the BIOS, reboot and go into the BIOS setup again, it's still enabled, but if I let the OS load it'll get disabled. I'm really at a loss here, how do I find out what's wrong? Could it be Ubuntu that does this?

/dev/hda = IDE/ATA
dev/sda - /dev/sdf = SATA

/dev/sda - /dev/sdd = RAID5 for storage
/dev/sde+/dev/sdf = RAID1 for storage

Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.

I had a little mission this week-end = my girlfriends 250Gb SATA hard drive laptop crashed this week (video card failure), and I wanted to help her by getting all her valuable data on an old Pachard Bell EasyNote laptop I have hanging around.One big problem : this laptop does not boot on CD drive, nor USB drive, and does not have a Floppy slot. There is an old hard drive with a lot of bad sectors in it, and I have a 80Gb IDE drive I want to put in.
My tools : a SATA to USB adapter, a IDE to USB adapter, a Ubuntu 9.10 LiveCD, a Windows7-run netbook, and the web.My goal : to configure the hard drive in some sort for it to install Ubuntu on boot (much like when you buy a laptop : the OS installs on first boot).I quickly found this to be impossible, as there is no Ubuntu pre-install format available (or that I found). So the next step was to get a complete install on the new hard drive, one way or another.First I tried cloning the 250SATA drive on the 80GB IDE drive, but this clearly led to an error (Grub error 18. It was looking for a 250Gb drive where I only fed him 80.)
Next step was to get some kind of LiveCD-like boot from the hard drive. This is made possible by using the UNetBootIn tool and the related Ubuntu Documentation. I met some problems during the real Ubuntu Install at the point where the laptop tried to format the drive the CD image was on. This other Ubuntu Guide gives a few workarounds and tweaks for that situation, but they didn't solve the issue for me.Final idea was to Live-CD like boot from the rubbish hard drive and install the system on the new hard drive plugged in through USB. This failed because the computer does not boot LiveCD-like on the old hard drive...
I'm kinda stuck on what to do now. I still don't have a nice boot on the computer (only a Live-CD like obtained with the UNetBootIn tool), and am still not capable of doing a "real" install on the Laptop.I'm aware that solving the boot-from-cd issue would bring me a faster solution (maybe!), but the idea was to get a hang on this so that I can install Ubuntu on my CD-free netbook soon (Although my netbook might very well boot on USB, but still).My final and last idea is to go buy some kind of adapter that would let me plug the two hard drives into the laptop at the same time, LiveCD-like boot on the new one, install Ubuntu on the old one (connected directly via IDE) and then clone the old one to the new one. But I wish I don't have to go to that extreme ;o)Writing this I just thought of one thing : I could install Live-CD like Ubuntu on a flash drive, launch it on my netbook and install Ubuntu on the new hard drive connected through USB... Would that work?

I'm facing a big problem with a corrupted disk on my wife's computer after she hard resetted the box after it froze up solid.Upon restarting it dropped into Busybox reporting something like
Quote:No init found. Try passing init= boot arg BusyBox v1.10.2 (Ubuntu 1:1.10.2.2ubuntu7) built-in shell (ash) (initramfs) ...This is VERY similar to a problem I had just a few weeks back with my own computer - see this thread for details of that. From that problem I learnt a lot, so I thought this would be quite straight forward, but I've ran into problems.The first thing I did was get a live disk, I chose Ubuntu Rescue Remix. It's a command line interface, which I am ok with, but I can't copy/paste the outputs here....so I am currently downloading System Rescue CD.sda1 is the root partition, it is corrupted. I used dd to make a back up of that by mounting sda7, and dding the whole partition image into /mnt/sda7/sda1.img .This seemed to complete properly, but, when I ran e2fsck on that img file, it wouldn't complete, throwing up a lot of errors.
Code:
ubuntu@ubuntu:/mnt/sda7temp$ sudo e2fsck sda1.img e2fsck 1.41.12 (17-May-2010)
Error reading block 2129920 (Invalid argument). Ignore error<y>? yes
Force rewrite<y>? yes[code]....[code]....
When I download and boot into System Rescue CD, I'll be able to run some more tests, in the mean time,I really want to save this disk otherwise my wife will be back on Windows permanently.

I'm wanting to run 10.10 server from a root disk located on an iSCSI server. My server is FreeBSD 8 running isc-dhcpd and is sharing out a 20GB iSCSI disk. I've run the server install CD (currently testing in VMWare), and it finds the iSCSI share without a problem. I'm able to install the OS just fine, but the problems start when I try to boot the installation. I'm booting off a gPXE iso until I can get PXE chain-loading figured out. My DHCP config looks as such:
Code:
host mm-iscsi
{
hardware ethernet 00:50:56:3f:3f:bf;
fixed-address 10.50.3.245;

Under 9.10, my laptop frequently freezes up and has to be hard-reset. At first I thought it was a Firefox issue because it happens most often when I'm on the web, but the computer also crashed on me while doing things in Synaptic, so it must be something else. I have an HP Pavilion z5000 with an Ati Radeon 9600 Mobility, 1.25 GB of RAM and 120 GB hard drive.

I've currently got 9.10 and have (somehow) managed to mess the system up already!It's a new computer so I'm not fussed about data loss etc, but is there a way to completely reset the system which will also format the hard drive (as it was a download that has messed it up!) without losing the O/S?

I feel a little awkward in this Control Panel: first time user. I installed the latest version of Ubuntu yesterday. All went smooth until I got to installing printer drivers. The setup went online and my system froze...everything froze. I had to do a hard reset. The printer installation went smooth the second time. So far this is the only problem I've had. No details needed. What I was wondering is if there's any way to check if the hard reset did any damage.

I currently have a problem where when xubuntu is restarted using the power button, it will prompt the user with grub asking which selection to boot (xubuntu recovery or xubuntu) this feature itself is fine, but for some reason there is no timer, which means that unless you hit enter, it will always be stuck on the GRUB selection screen. I am wondering if there is any way to change this, is there anyway to enter a timer into the system so no matter what, after x seconds it will boot xubuntu?

I have forgotten my root password for MySQL, what can I do to recover it, I've found a few guides but they don't work on the newer versions of Ubuntu.I am running on Ubuntu 10.04 server so MySQL is an upstart job so the methods I've seen with launching it without the access checks haven't worked for me

I have forgotton my root password for mysql. I followed some instructions on a website and now I am not sure what i have done?Basically, when I now try and start mysql I get a notification that i have converted the init script to an upstart. I dont know what this means.
Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start( utility, e.g. start mysql mysql start/running, process 20301.

After upgrading from 10.04 to 10.10 I have had some problems booting my Ubuntu. It all started when restarting after the upgrade, and I got the error;
Code:
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting / sys/ on root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or dirctory
Target filesystem doesn't have /sbin/init.
No init found. Try passing init= boot arg
BusyBox v1.13.3 (Ubuntu 1:1.13.3.1ubuntu11) built-in shell (ash)(initramfs) After searching the Internet, I found a "solution". I just had to boot with a USB stick with the Ubuntu Rescue Remix (the normal Ubuntu USB won't boot either), and i wrote;
Code:
sudo fsck /dev/sdb5
Now I could start my Ubuntu again. So whats the problem? If I turn off my computer the normal way, there is no problem, but if I log off, put it into sleep mode, if something happens and I have to turn it off with the button it goes back to the first problem, and I have to reboot it with the USB stick and fix it all over again! If I don't have the USB stick with me, I probably wont be able to use my laptop!
