  • restoring grub when Windows 7 MBR lost it

    - by Trent Hall
    My dual boot desktop was running only Windows 7 until it crashed on a windows update. Couldn't get it started again even after all the usual things that might fix it, so I installed Ubuntu 12.04, which has worked very well. unfortunately Carbonite doesn't run on Linux yet, and so I called Microsoft support to see if we could be Windows 7 up and running. Their attempts to get Windows 7 running resulted in writing a new MBR for windows, which failed and also somehow caused the loss of ability to boot into Ubuntu also. How can I get back to Ubuntu? I don't want to lose my settings in Ubuntu. Thanks... Trent

  • Sales Manager: "Why is time-estimation so complex?"

    - by Tim
    A few days ago a sales manager asked me that question. But at this moment I didn't know a answer which he can understand. He isn't a programmer! At the moment I work on a product which is over 8 years old. Nobody thought about architecture or evolvability. I have a swamp of code in front of me every day which is not tested. Because of that, time estimates are very difficult for me. How I can describe that problem to an salesman? Not only my swamp-code-problem, but general!

  • Stuck while Booting Text Mode in Ubuntu 12.04?

    - by sameetandpotatoes
    I edited the /etc/default/grub file and changed: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=”text” This does make Ubuntu boot up into text mode; however, it gets stuck while booting up and it does not show me the login text. Instead it says something like this: Begin running /scripts/init-bottom USB hub found ...More irrelevant things... *Stopping LightDM Display Manager I can press Ctrl + Alt + F2 and see the login and boot up like normal, but is there any reason for this? How can I change it so it does not get get stuck? Edit: After 5 minutes, a new line came up: 557.1206341 ieee80211 phy0: channel change: 5540 -> 5560 failed (3).

  • Default file manager changed, can't change back

    - by user16171
    (Using ubuntu 11.04) I tried to open a torrent file in chrome, and it asked for my default application, so I clicked Transmission, and then I got an error: "Failed to execute default file manager, Failed to execute child process "transmission" (No such file or directory)." Now if I click on any shortcut on the unity bar, such as the trash folder or the icon for my portable hard drive, I get this error, as well as with any download or folder from chrome or firefox. I can't seem to figure out how to fix this, as there seems to be no easy way to do it.

  • Ubuntu - Black Screen After Suspend

    - by EssAm
    I used Ubuntu with no problems and I upgraded to 11.10 and everything was fine. But when I did my first suspend I was not able to boot again, all I got was a black screen no bios screen, nothing just blank, I tried doing hard reset but when I power on again same happens. I tried ctrl+alt+delete F1-F12 but i think the keyboard is not working, also tried booting from CD but all I got was blank screen, the hard disk light is not blinking at all so i'm assuming it's not trying to boot. My laptop is Toshiba satellite with ATI Radeon graphics. Hibernate was working fine though. I searched the net for solutions but with no luck. Any ideas?

  • How exactly does gnome manage laptop suspend events?

    - by jcline
    The reason I ask is that, while suspend under lid closure and fn-F4 work perfectly in the Ubuntu (gnome) desktop, I cannot get them to work when using a different window manager (fvwm) on my thinkpad X201. I thought this was taken care of by gnome-power-manager, but when running gnome-power-manager within fvwm, I get no suspend from lid closure or fn-F4. I tried starting other processes as well, like gnome-settings-daemon, but this had no effect. I also tried fiddling with acpi settings, without sucess.

  • GRUB 2 Error : No such disk

    - by Chandra Sekhar
    I have gone through many pains to boot through my windows 7 partition. I had windows 7, then one fine day I installed Ubuntu and again formatted the partition where Ubuntu was installed only to find the my Windows does not boot(Probably corrupted MBR). I again installed Ubuntu later but the Grub could not detect windows. So I manually added windows by editing the file 40_custom. But when I select the win7 entry in the grub, it displays the error : no such disk. What do I do?? Additional Info : Ubuntu version : 11.10 x64|| Win 7 Home premium, 64 bit|| While in the process of debugging I once also came across the error : Sector 32 being in use by FlexNet.|| Strongly in need of booting my Win 7 without any formats or fresh OS installations. Thankful for any Diagnostics and Solutions to my problem.

  • Dealing with "I-am-cool-and-you-are-dumb" manager [closed]

    - by Software Guy
    I have been working with a software company for about 6 months now. I like the projects I work on there and I really like all the people there except for 1 guy. That guy is technically smart, and he is a co-founder of the company. He is an okay guy in person (the kind you wouldn't want to care about much) but things get tricky when he is your manager. In general I am all okay but there are times when I feel I am not being treated fairly: He doesn't give much thought to when he makes mistakes and when I do something similar, he is super critical. Recently he went as far as to say "I am not sure if I can trust you with this feature". The detais of this specific case are this: I was working on this feature, and I was already a couple of hours over my normal working hours, and then I decided to stop and continue tomorrow. We use git, and I like to commit changes locally and only push when I feel they are ready. This manager insists that I push all the changes to the central repo (in case my hard drive crashes). So I push the change, and the ticket is marked as "to be tested". Next day I come in, he sits next to me and starts complaining and says that I posted above. I really didn't know what to say, I tried to explain to him that the ticket is still being worked upon but he didn't seem to listen. He interrupts me in-between when I am coding, which I do not mind, but when I do that same, his face turns like this :| and reacts as if his work was super important and I am just wasting his time. He asks me to accumulate all questions, and then ask him altogether which is not always possible, as you need a clarification before you can continue on a feature implementation. And when I am coding, he talks on the phone with his customers next to me (when he can go to the meeting room with his laptop) and doesn't care. He made me switch to a whole new IDE (from Netbeans to a commercial IDE costing a lot of money) for a really tiny feature (which I later found out was in Netbeans as well!). I didn't make a big deal out of it as I am equally comfortable working with this new IDE, but I couldn't get the science behind his obsession. He said this feature makes sure that if any method is updated by a programmer, the IDE will turn the method name to red in places where it is used. I told him that I do not have a problem since I always search for method usage in the project and make sure its updated. IDEs even have refactoring features for exactly that, but... I recently implemented a feature for a project, and I was happy about it and considering him a senior, I asked him his comments about the implementation quality.. he thought long and hard, made a few funny faces, and when he couldn't find anything, he said "ummm, your program will crash if JS is disabled" - he was wrong, since I had made sure it would work fine with default values even if JS was disabled. I told him that and then he said "oh okay". BUT, the funny thing is, a few days back, he implemented something and I objected with "But that would not run if JS is disabled" and his response was "We don't have to care about people who disable JS" :-/ Once he asked me to investigate if there was a way to modify a CMS generated menu programmatically by extending the CMS, I did my research and told him that the only was is to inject a menu item using JavaScript / jQuery and his reaction was "ah that's ugly, and hacky, not acceptable" and two days later, I see that feature implemented in the same way as I had suggested. The point is, his reaction was not respectful at all, even if what I proposed was hacky, he should be respectful, that I know what's hacky and if I am suggesting something hacky, there must be a reason for it. There are plenty of other reasons / examples where I feel I am not being treated fairly. I want your advice as to what is it that I am doing wrong and how to deal with such a situation. The other guys in the team are actually very good people, and I do not want to leave the job either (although I could, if I want to). All I want is respect and equal treatment. I have thought about talking to this guy in a face to face meeting, but that worries me that his attitude might get worse and make things more difficult for me (since he doesn't seem to be the guy who thinks he can be wrong too). I am also considering talking to the other co-founder but I am not sure how he will take it (as both founders have been friends forever). Thanks for reading the long message, I really appreciate your help.

  • Login speed varies over time

    - by Brock Dute
    I have a weird problem with my Ubuntu right now. My login speed is never consistent for months, sometimes it changes within weeks. What I mean is, for example, within 2 weeks, boot time is really fast and speedy but then say after that, boot time becomes noticeably slower. Usually, right after the ubuntu login sound plays, my desktop would've finished loading already but sometimes, the ubuntu login sound is already done playing and I'm still in this stage of the login -- image, exactly like that. Any reasons for this? Sometimes it slows down after updates (which I think is kind of normal?) After a few reboots, it becomes fast then randomly it becomes slow again.

  • Why dosn't Ubunto like my HP Pavilion G7?

    - by user109379
    I installed Ubunto onto my HP Pavillion G7 1330dx without much problem, but it took 3 or more tries to get it to boot up after. Then , I started over and installed Mint, no problems installing or booting up. BUT, I decided I I liked Ubunto better so I wiped my hard drive and installed Ubunto ( this time the 32 bit) ,It runs great once i finally get it to boot, it takes 3 or more tries again. Whats the deal? I really like it but really don't know what I'm doing. I've been a Windows guy until a couple days ago.

  • Connection manager detects network but won't connect

    - by Carson Chittom
    I've just installed 12.04 on my home desktop. Because of where it's located, in order not to have my children tripping over cat5 cable, I've got a cheap 802.11n USB device plugged in, which uses a Realtek 8192CU chip. The house wifi is protected with WPA2. Ubuntu's Network Manager detects the network, but connecting to it just times out and asks for the password again. I'm sure I'm using the correct password. No other computers on the house network are having any difficulty. This device previously worked correctly with both Windows 7 and OpenBSD in the same machine. The linux-firmware package is installed (from the disc) at version 1.79, and /lib/firmware/rtlwifi/rtl8192cufw.bin is present. dmesg|grep rtl only shows the "loading firmware" message. I've tried Google, but I apparently can't find the right set of words to plug in, because I haven't found anything related (lots of "doesn't work at all," but nothing matching my circumstances). Any help would be greatly appreciated.

  • Ubuntu hangs on booting up after a update

    - by alFReD NSH
    I've made a clean install yesterday, for the first time restarted, everything went good and then after I updated packages and copied my old home directory to replace the new one, when I restarted it hung when it was booting. I tried reinstalling again and doing the same thing, but again same thing happened. Here's what I see, before when the Ubuntu logo with the five dots is shown: Then after that, 3 or 4 of the dots will load and hangs there. If I press arrow up before that, this will be shown I started my laptop again today(the pictures are for the day before) and after that, boot up with live CD and got the logs. dmesg: http://pastebin.com/aVxV7BQF syslog: http://pastebin.com/4E2BrRUK And some info: alfred@alFitop:~$ uname -a Linux alFitop 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux lshw: http://pastebin.com/AZbKJmsT sources.list : http://pastebin.com/2HazmuyV My problem is a bit similar to here: http://ubuntuforums.org/showthread.php?t=1918271 Though I didn't change my x.org config. Only changed home directory and updated packages. I've tried memtest and fschk, both passed. In the recovery mode boot option, I've also realized that same things happen in failsafe graphical mode. But when I go into the network mode, I can boot up my system, but of course same the graphics are just basic. Adding blacklist intel_ips to /etc/modprobe.d/blacklist.conf solves the first message, but still I get the broken pipe and CPU stack traces. The current kernel version is 3.2.0-25, I've tried booting up in the 3.2.0-23(the one the installer came with, but same results.) Also uninstalled apparmor, didn't help. I've installed Ubuntu again, this time without copying the home directory, also same result. --- UPDATE --- This problem was solved before with removing backports, but its back again! I've updated my laptop last night and the problem came back. It's definitely one of these packages. My /var/log/apt/term.log and /var/log/apt/history.log. I'm almost having the same situation. --- UPDATE --- I realized this also have happened on times that I have updated(haven't restarted after it) and my computer power has been cut off and its shutdown due to lack of power. And I realized if I just do as I answered but not in somewhere without GUI(networking mode has the GUI) it wouldn't work.

  • Grub failure after cat removed USB drive

    - by user76270
    I had a perfectly working Ubuntu Server system with U12.4 and Server installed and was setting up the mail system. When I was absent from my computer room my cat (furry type) apparently got to play with a USB dongle on an extension cable and removed it. The system went berserk and now will not boot. I ran Ubuntu 12.4 on the install disk and the directory structure and every thing appears to still be on the drives. How do I recover the GRUB boot section without the system repartitioning everything and wiping everything else? Please I am a total newb when it comes to Linux errors and fixing them.

  • Booting briefly shows CLI login and then black

    - by lepusfelix
    When I boot to Ubuntu on my dualboot system, it appears to boot normally, up to the point when I would normally expect to see the lightDM graphical login screen. However, I see a CLI login screen, which I assume is tty1. Before I get a chance to actually login to it, though, it drops to a black screen with a flashing cursor. Pressing ctrl+alt+f1 does nothing. When I hit the power button on the laptop, I see the usual scrolling text as Ubuntu shuts down. I know that this is related to me having installed the proprietary ATI drivers for the video card. Purging the drivers gave me back a GUI, but unfortunately no working desktop environment, and switching to the mesa drivers returned me to the black screen issue. The only way I can get a stable working CLI is through booting to advanced options and choosing a root shell prompt, as even the failsafe X session doesn't function for me.

  • Cannot Update through Manager or Terminal/ Software Center Does Not Work

    - by BROBA
    I installed Tor a few days ago via the terminal. I deleted some hashtags in the gedit polipo, and changed my proxy settings in chrome, but was unable to make it work and have since changed all of it back. I then downloaded the Tor browser bundle which works great, but ever since then have been unable to download updates or new software. The update manager says to "check internet connection" and the software center displays a mostly blank screen under apps like "rhythmbox" and just says "available from main source" when I click on "use this source" a refresh symbol appears on the upper right corner of the software center for a split second, and then nothing happens. The app does not download and isn't available in the dash. When I try via the terminal it says it's unable to connect to my ip address. I tried changing the server and unchecking all the repository options for software sources, all to no avail. WHAT DID I DO?????

  • How to completely remove wicd from 12.04?

    - by danijelc
    I had issues with WiFi so I removed Network Manager. I booted Windows OS (dual booting Windows 7 and 12.04) to download wicd 1.7.2.4. Extracted it and installed. However, wcid worked properly with Wired Connection but could not connect to WiFi. So, I re-installed Network Manager which works properly now, and wicd connects to WiFi too. As soon as I disconnect from Network Manager, wicd connects only to wired. At this point, I wanted to remove wicd but apt-get returns no wicd installed, can't see it in Synaptic or Software Center, but only in Applications list under Dash home. Of course wcid icon shows connections, and resulting connected, so my system shows both applets for wicd and network manager in the top panel. When running dpkg commands, wicd is not listed as installed package. Any suggestion how to remove wicd? Consider that I started with Ubuntu just few months ago so my knowledge base is limited.

  • GRUB2 panic: "No such partition"

    - by Android Eve
    I managed to install 10.04 on a system that already has 8.04 (separate partitions, of course). It also installed GRUB2 onto the MBR. After discovering that there is no menu.lst anymore, I edited /etc/grub.d/40_custom to point to where my other OS partitions are: menuentry "Ubuntu 8.04" { set root=(hd0,0) linux /boot/vmlinuz-2.6.24-28-generic initrd /boot/initrd.img-2.6.24-28-generic } menuentry "Windows 7 Ultimate 64-bit" { set root=(hd0,2) chainloader (hd0,2)+1 } GRUB2 displays the menu with those entries but when I select any of them, it refuses to load them, saying "No such partition". I know the partitions are there, as 10.04's "Disk Utility" sees them without any problem. How do I get GRUB2 to recognize them?

  • Unable to login following permission changes in device manager (11.10 + Gnome)

    - by Symanuk
    (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers

    I'm trying to install Ubuntu on a Samsung ultrabook via a usb stick. I've tried 12.04 both regular and alternate on 3 different USB sticks but not having success. The laptop just keeps booting into windows. I used unetbootin to create the USB image as this worked for when when doing a toshiba ultrabook installation. I reset my Boot Menu to be 1 USB HDD 2 USB CD 3 USB FDD 4 SATA HDD SanDisk SSD u100 128GB Then F10'd but no success, still boots windows. I've tried changing UEFI boot support to be enabled and I've tried changing PXE OPROM to be enabled but neither has helped.
