Ubuntu :: Accidentily Overwrote Windows And Other Things?
Feb 19, 2010
I just did something that is moderately serious in my book.while trying to put a iso/img to a USB drive using "dd" command (actual command: "dd if/=/home/<username>/Desktop/<image file name> of/=/dev/sda1"), I accidentally wrote to /dev/sda1 (which is my windowspartition on this dual booted computer). When i try to boot into windows, it gives a error that it cannot find the parition. the iso was about 400meg, it was a install iso for another form of linux (arch linux).Is there anyway that I can get my windows partition to work again, or am i just going to have to say goodbye to all my music, pictures, etc. And I think some of my teachers require me to use windows based software... So I would like to eventually get back into windows though.I am running Ubuntu 9.10, I am on a laptop (HP HDX 16t)I am going to get ubuntu back onto my netbook (i destroyed that earlier tonight by deleting a partition that had the bootloader on it... i am just wiping that though)

This question is only partially linux-related, but I accidently typed cp file /dev/sda2 instead of cp file /mnt/sda2. The first 300 bytes or so of the ntfs partition were overwritten and now it can't mount and can't boot. I figured I would try copying the first 4096 bytes from another ntfs partition and see if that gave it enough to at least boot. It didn't and I'm wondering if there's any way to fix this sort of thing easily (without downloading an entire Windows 7 DVD) and what exactly I overwrote that was so important.

I wanted to install Ubuntu 10.10 onto a 16Gig USB key and did so by booting with a Live CD and doing the install to /dev/sdc1 (which is the USB key). It installed fine to the USB but it also installed grub MBR to /dev/sda1 (doh!) .. so now I can't boot into my main HD unless I have the USB key plugged in and I select the correct kernal on /dev/sdc1 to load from on the grub boot menu. If I try booting without the USB key I get... error: no such device: <long device id number here> grub rescue> _

I'm working through some problems in a beginners programming book. The author mentions a formula for calculating the number of ways of picking out n things from a collection of m of them:
Code:
/ m m!
| | = -----------
n / n! (m-n)!
But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.

when i powered on my pc today i saw that windows manger, cursor and some other things have disappeared. My hard disk has problems with bad sectors, so i guess that could cause it. How can i restore previous state? I have xubuntu 11.04

I have a 230GB hard drive wich I don't know it's name.I have a 207GB windows vista partition and the rest of it is for linux (Ubuntu).Today I decided giving it all space to Ubuntu Linux ,but didn't want to lose all my data from the windows partition.I thought that by deleting all things except the folder with my data and leaving enough space to shrink and make enough room for another partition to put my data folder.The logic is that i could then format that partition wich previously was windows and use it all for ubuntu without losing data.After having ubuntu installed i could copy my data folder to /home and then delete the previous partition and make /home bigger.The problem is that after i freed the space,when using Gparted to shrink it says that the partition has bad sectors or the filesystem has problems and so it can't do some operations.
What could have went wrong?It told me to do chkdisk but as i deleted all the windows files and i can't boot into it anymore.I used the vista dvd to do that.I rebooted 2 times as it says and after that when trying again nothing changed.I tried to use ntfsresize with the --bad-sectors argument and also the -f argument but it's useless.At the end it says it won't do anything until the ntfs filesystem get repaired.Or it says it is too risky to continueIs there any way i could do some superforce command to resize it without losing data?Please don't tell me to put it on an external storage cause i have like 70GB of datas to save...no i don't have an external hardrive

I've just installed kubuntu 10.04 x64 and I'm slowly working through lots of little niggly problems that I'm having getting it all set up.My graphics seem VERY sluggish doing things like opening and closing windows, popping up menus etc.I have an Athlon II 250 3.0ghz processor, 2GB RAM and onboard graphics ATI HD2100 (740G chipset).I tried to get the proprietary graphics driver installed to see if that made any difference but it wouldn't recognise the onboard graphics, a bit of googling seems to suggest they have actually dropped support for this model?After removing the proprietary stuff it seems even more sluggish than it did before.

ive got a windows partition and a ubuntu-10.10 partition. i just tried to reinstall windows on the first one - but things didn't work out properly. after the first restart the pc just hung in the first boot screen - it wouldn't boot from the windows cd or the harddrive. every time i restart the computer it just hangs in that screen. i can't even choose to boot from cd/usb to use a livecd and rescue my files on the ubuntu partition. its like the keyboard doesn't work anymore. ive tried both a usb keyboard and one of the old kind with the prongs. so i cant get into ubuntu.
here's the screen, it pops up a second after i restart. usually the pc just boots up a couple seconds later and i can choose beteen win/unbuntu; or i can just press 'esc' and choose to boot from usb. but now nothing is happening, the keyboard doesn't seem to work, and it wont go passed this screen.*edit* actually the keyboard is working, because ctrl-alt-del restarts the computer, but thats about it..

I was gonna install OpenBSD 4.6 on my PC and I accidentally overwrote my boot partition.
Initially my partition table looked something like this:
Quote:
This doesn't look like a partition table
Probably you selected the wrong device.
Partition 4 does not end on cylinder boundary.
Partition table entries are not in disk order
That's what my partition table looks like according to fdisk. So I'm wondering how I'd go about recovering /dev/sda3 (what /dev/sda3 was before I blew it up).

I updated through the update manager the other day and after I shut my computer down and turned it back on the next day, all my icons on my desktop disappeared and I can't access my files or my applications. It gives me this error when trying to access my files in my desktop.
Could not open location 'file:///home/anubis/Desktop'
No application is registered as handling this file.
I posted a new thread about this the other day and somehow the thread disappeared too. what do I need to do?

I just recently upgraded to Ubunutu beta 10.10, & now whenever I minimize anything, I cannot find where said program is going to. The programs do not appear anywhere, like before where they were on the bottom panel or whatever.

So I'm trying to get mediatomb to run at startup automatically. I went into System Settings -> Startup Applications and added a new one with the command 'sudo mediatomb.' Unsurprisingly it did not work. What am I doing wrong?
Also, what do I use in ubuntu to check for updates to all of my installed applications?

So I've just recently started using awesome, but I was wondering why things look like this and how I can fix it
Just wondering why it's so 'un-decorated' I guess, I assume I'm just not running something I should be at startup, it happens on all programs and windows. http://i51.tinypic.com/afac5c.png
It's looks like windows 98
Here's another screenshot of it http://i54.tinypic.com/349ary9.png
Just all the borders, menus and stuff look horrible.

When I (try) to upload files to Ubuntu One; generally, the upload doesn't happen. What does happen is [on] the bottom panel says: "Sending request to files.one.ubuntu.com . . ." It may sit there like that for hours without an upload happening. Once, I left my computer on and left for a couple of days; when I got back it had uploaded. Is this the norm? Is there something wrong on my end (other than PBKAC)? What can I do to speed things up? Or can they be speeded up? Is the description of Ubuntu One one thing and the reality something else?
What to do?

I've installed Ubuntu 10.04 and I wanted to customise it a little (splash screen, login screen, window theme) - problem is, all of the tuts on the net have been written for 9.xx or lower and none of them seem to work with the version that I am running (I can't remember why right now because I looked this up a few days ago but there was a tab missing in 10.04 that was there in 9.xx and below). how to customise these things running Ubuntu 10.04?

this is totally weird and i have no idea what's happening. i have a 64bit ubuntu 10.10 (just like the title says). i've been having random (really out of the blue) slow ubuntu response. so slow, the mouse pointer works stops works kinda thing. i can't open any program and clicking the power button doesn't work. i have to hard restart it (holding down the power for a couple of sec). this is really making me mad since i'm afraid for my hardware life and to be honest - not very impressed with ubuntu.
i have no idea why this happens and i really need help on this subject, otherwise i'd just have to look for another OS (and i would like not to) also - the computer is new so i don't think it's a hardware problem, but if there are tests i can do to check it i wouldn't mind

I've been running Linux for about 3 years now. I still am having difficulties understanding some of the basic unix and linux software and their dependencies.
What I am wanting to do, simply for my own amusement, is to strip the OS down so that I am only running software that I need. Then I want to build it back up with X and some sort of desktop.
Right now I have a stock Ubuntu 10.04 installation from the alternative DVD. Right now I sit at 643MB and 14MB of ram. Of course I would want it to be lower.
Here are the programs currently on the chopping block. I need to now if I honestly need them or not. I state next to the software whether or not I know what it is. code...
So obviously I have not a clue about many things still, and if you've caught an error in my descriptions then I have less of a clue than I thought.
I just need to know what the system needs to run. I like the basic commands like less, grep, free, df, du, adduser, usermod, apt-get, dpkg, cp, mv, rm, mkdir, ect. What I don't need are things like w3m telnet(Unless someone knows something I don't), memtest+, and I don't ever use cron, but I also don't know if it does something behind the scenes that is vitally important. I remember trying to get rid of memtest one time and it wouldn't boot after that. Any idea why?

For some odd reason when I logged into Ubuntu Lucid Lynx today, Caro dock is all messed up and the close, minimize, etc buttons are on the left on all of the windows.Yesterday all was fine. The buttons were on the right side and cairo dock was fine.Now, it is all messed up. I even brought the compiz icon up and clicked reload WM and that did not even fix it.

I have been trying to go through Beginning Ubuntu Linux but there are inconsistencies with what the books says and what it looks like on my computer. For example, The book speaks of a Device Manager that should be located under System > Administration > Device Manager. It does not appear for me under System > Administration.
The book I have was published in 2006 and I am using Ubuntu 10.10.

I got the conversion to work for hiragana to kanji by downloading the language support, but now I can't input things in katakana there is no option for it on Anthy. I looked all over. There's no drop down menu for me to change it. One more thing, how do I change the default font to a different one for Japanese scripts?

Alright maybe I posted my problem in the wrong forum, but I need to fix this because I can't update other things like JDK because of the dependancies.[URL].. That's my original post.
Should I just uninstall FF and then run the update? If I remove FF, will I lose favorites ect?

i think installed Ubuntu 10 2 weeks ago and it was working as far as this problem is concerned and then recently stopped showing Skype and the internet connection thing that is two arrows when connected. Both items are supposed to be next to the sound icon. You can see the blank area in the attached pic. I also do not get the top bar and bottom bar of the desktop about every 2 boots.And why is it when i save to the desktop i have to go to home>desktop instead of straight looking at the desktop. Sorry this is all happening at once and maybe it is all related?

I'm using ubuntu 10.10 on an hp pavilion dv9620.
For some reason, all of the sudden;
-my computer quit waking from suspend
-when my computer reboots (because I had to hold in power switch until it restarted) some of the items on my screen looks wierd for a few minutes, like there are tracers on some items (dock, top of screen, etc)
-when i try to wake my computer from suspend, the screen is a funny gray color with wierd blobby shapes that move around a little bit. And of course, doesn't load GUI or anything like that, just gray screen.

I understand the basics, where certain files are located, how to change basic things, and very basic stuff with the command line (I use it to organize my files mainly). If at all possible could you supply me with a guide - be a website or a book to:
1) Just the general layout of the system (whats in the depth of the /etc folder and what naught)
2) How to more efficiently use the command line. As in where I am not giving in and using the GUI all the time.
3) What programming language(s) should I learn. I am thinking C and Python to start.
