• Windows dont boot after Ubuntu installation

  - by Diogo Garcia

  I have had serious problems installing ubuntu and Windows and have dual boot. Recently i installed booth operating systems, ubuntu was the lastima one, and after that my computador was booting directly to Windows 7. I used my ubuntu USB live to repair the grub, and o could repair. Now i initiate my pc with grub 1.99 and ubuntu and Windows are recognized, but Windows gives an error and dont initiate, sugesting to use Windows DVD to repair the grub. I tried that but with no effects on be behavior. I have a new asus n56vm. This conflits with gpt and mbr have been a huge pain to me. I dont know what to to, i installed ubuntu and Windows inumerous times since i bought this cumputer 2 weeks ago. Best regards!

• My Ubuntu LiveUSB won't boot after formatting it on Windows XP. HELP!

  - by Bigyellow Bastion

  I formatted because the Windows XP I was using wouldn't let me view the drive in the window without formatting first, so I just said what the heck. Turns out, after using the Linux USB creator, placing the ISO on disc properly and booting, BIOS hangs; no bootloader, no startup, nothing. Windows XP's formatting screwed something up with my USB's filesystem, and I'm uncertain of what to do. Help?! My business depends on me using an OS, so prompt ideas are a must and very appreciated(no money). PS: I checked the contents of the disc, and they are all okay.

• Problem in installing Ubuntu 12 using USB

  - by Hitesh Bhatt

  I have a Sony laptop (VPCEH25EN) and i am trying to install Ubuntu 12.04 LTS. I downloaded the iso named "ubuntu-12.04-desktop-amd64.iso". For installing i created a bootable USB using UltraISO. When i booted the USB it hangs and shows " Booting from USB ", I even left it for hours and it didn't moved a bit. When I booted the ISO in Virtual Box, it ran well. I even used other tools to make a bootable USB, then it says " BOOTMNGR missing ". Please help, I am new to Ubuntu and my optical drive is fried. Thanks in advance..

• 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?

• Live CD boot/installation problem, blank screen - 12.04

  - by traubi

  I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom) I checked the live system with my laptop.works well except it also starts of with a black screen and a grey box at the bottom. I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters. I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text. I would be happy for any advice on this matter

• Problems after installing Ubuntu 11.10

  - by Andrew Orr

  I'm having trouble with Ubuntu 11.10. It has to do with nomodeset. After I boot into Ubuntu, it goes to a purple screen for about 10 seconds and then goes blank. After that nothing happens. I've read other people's questions about this and I know it has to do with enabling nomodeset. This worked for me when I was using the LiveCD mode, but now Ubuntu is permanently installed as a dual-boot system. Going into recovery mode doesn't work, pressing "e" in the boot loader and writing nomodeset after quiet splash doesn't work either. Holding shift any time it's booting doesn't work. I don't know what to do anymore. I have an HP Pavilion dv6 laptop with an AMD A6-3400M CPU, and my GPU is an AMD Radeon HD 6520G. I've never worked with Linux before so taking me through this step-by-step would be great. Thanks!

• 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.

• fix a broken ubuntu installation from pendrive

  - by interstar

  Something went wrong in the upgrade of my Ubuntu 13.04 to 13.10 The upgrade basically crashed halfway through. On booting I was thrown into a maintainence screen. I found some online instructions for fixing with the package manager ... Which seemed to do a lot of setting up. But then crashed saying package is in a bad inconsistent state. Now I'm in a position where Ubuntu starts again, but goes into a low-res screen and there's no WiFi. I have no Ethernet cable connection but I did download the 13.10 iso on another machine and put it on a pen drive. So I'd like to know there's a way of asking the machine from inside Ubuntu to redo its upgrade from the data on the pendrive rather than WiFi. Is this possible? Cheers Phil

• Slow wifi with D-link DWA-160 A2

  - by Tommy Brunn

  I recently bought a USB wifi adapter for my new desktop computer. It's a D-link DWA-160 A2. From the start it didn't want to work at all, but after unplugging and then plugging it back in, it seems to work. However, my browsing is painfully slow. NetworkManager reports the connection to be at around 78-85% signal strength, which seems perfectly acceptable. Is there anything I can do to make it faster? I'm dual booting with Windows 7, where it seems to work fine, so I'm guessing that the problem occurs because of crappy drivers.

• cant get ubuntu to work with windows 8

  - by John Mark High

  ive been trying to dual boot Ubuntu with windows 8 but so far I haven't been able too. the laptop im using is a HP Pavilion g6-2240sa pre-installed with windows 8. ive made the bootbale USB with Ubuntu 12.10, it installs but when I restart the computer boot straight into windows, no grub boot options. I can get into Ubuntu once by doing an advanced restart and booting from the Ubuntu partition. I can use Ubuntu fine but once I restart or shutdown, I do the advanced restart again and the Ubuntu partition is now gone and I have to reinstall. i used this tutorial to install Ubuntu, http://www.youtube.com/watch?v=wNCSbTyUzoM After i have to reinstall and still no grub boot menu, i used the boot repair to re-install it. once i rebooted the computer it went straight to windows again and the Ubuntu partition was gone. can i dual boot windows 8 and unbuntu 12.10 with the grub so i can pick what OS to boot into when the computer is starting, and without the partition going AWOL???? Thanks in advance

• Grub does not autoboot the default option after upgrade to 12.10

  - by Petr Kozelka

  I recently upgraded Ubuntu from 12.04 to 12.10 and since that time, the system does not automatically boot. It always opens the boot menu, and I have to press Enter to make it boot Ubuntu. It seems to be ignoring the timeout value, and using a 'neverending' timeout. There are no other systems (no dual boot), only the options originally installed by default Ubuntu 12.04 installation. My /etc/default/grub has only these effective options: GRUB_DEFAULT='Ubuntu' GRUB_HIDDEN_TIMEOUT=1 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=1 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_TERMINAL=console I experimented with GRUB_DEFAULT, giving it values '0', '1', 'Ubuntu' but nothing helps. Yes I always run update-grub afterwards. How can I make the system booting again ?

• What features of old computers helped you learn to be a better programmer?

  - by David Cary

  What features of old computers helped you learn to be a better programmer -- but don't seem to be available on new computers? I imagine that, while educational, you are really glad some features are gone, such as programs ran so slowly that I could almost see each pixel being plotted, so I got a visceral feel for the effect of various optimizations. I imagine other features you may be a little nostalgic for, such as I could turn on the computer, and write a short program that printed "Hello, World" on the printer, before ever "booting" a "disk". (I'm hoping that this is constructive enough to avoid the fate of the " What have we lost from computers 20 years ago ?" question).

• 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.

• Broken BURG install after backup/restore

  - by WindowsEscapist

  Long story short: BURG is stuck in text mode and I can't seem to get it back to the eye-candy. I have purged and then re-installed to no avail. I am running 12.04. The long story: I originally installed onto 12.04 using Super-boot-manager (BURG-manager) and then stopped using it in favour of GRUB because I had too many entries. I then had to backup and restore Ubuntu (partition was deleted and re-created) due to unrelated issues. I re-installed GRUB2 and booted into Ubuntu to re-install BURG, but after re-booting it appears to be stuck in text mode (looks exactly like GRUB 1). Any ideas? I know I'm not supposed to be using it on 12.04 (I think) but it worked before, so what's up?

• failed to get i915 symbols, graphics turbo disabled error on boot

  - by Gaurav Butola

  Whenever I boot my laptop, I see this message and it makes the boot process very slow as my screen stays black for a long time before this message appears. It shows just for a split second but today It got worst when my system couldn't boot and stuck on this error, I did several reboots but still couldn't pass this boot error message, then after sometime it fixed itself and now I can use my system as normal. I didn't pay much attention to the error when It was there for just a split second and making my boot process slow, but now that it has stopped me from booting into my system, I would like to know why this error occurring. Error-- ...failed to get i915 symbols, graphics turbo disabled....

• How do I install Ubuntu on an iMac 27"?

  - by jml

  I have a beautiful 27" iMac. I would like to run Ubuntu on it natively, dual-booting with OS X. I have rEFIt installed, and I can boot into the Ubuntu 10.10 CD, kind of. Here's what happens: I select the CD from the rEFIt menu It loads for a while, then flashes up an aubergine screen with a very low-res picture of a human, an arrow and a keyboard It sits there for a while It changes to 80x25 console mode The screen then goes black, as if nothing is displaying to it All the while, the CD is churning away as if something is reading from it. What do I do?

• Bare-metal mode for Ubuntu

  - by user1071136

  I'm interested to benchmark a console-mode application, and would like to reduce to a minimum any interferences from other processes in the system. Is there an easy way to boot into Ubuntu 12.04 in a "bare-metal" mode ? I'm still interested in casually booting a "desktop" version of Ubuntu (so will prefer to avoid permanent changes), and would like to avoid installing a separate Ubuntu-server version. My use-case is the following - Application is single-thread and console-mode only. Test-box has 12GB of memory. I ssh into the test-box. Seems I can skip at least Unity, X-server and their dependents.

• How can I get wireless working on an HP-Mini 110-3150?

  - by jfmessier

  I just got an HP Mini 110-3150, and booting from an external hard disk with Ubuntu 10.10 works all fine, except that there is no wireless detected. I noticed that the Wireless indicator is red under Ubuntu, but is enabled under whatever Windows 7 I got on it. So, I understand that it may not get detected at all by Ubuntu at startup time, and there is no manual switch that I can simply slide to turn on/off. How can I get the Wireless device turned ON by default at startup time, and is there any special driver I need to install (proprietary or not) to get it working ? Merci :-) Update: When actually installing on the computer, as a new install, the NIC is not detected at first, but upon restarting, I get a notification of a closed driver available for the wireless. Once installed, updated and restarted, it works fine.

• Switching to Kubuntu results in low graphics mode

  - by HackToHell

  I looked at some screen shots of Kubuntu and I liked it so I went to Synaptic and installed the kubuntu-desktop package and set my desktop window manager to kde and rebooted. After reboot, I saw Kubuntu splash screen then this message; running in Low Graphical Mode. Then I was not able to dismiss the message because my mouse did not work Seemingly How to Geek had the same problem http://www.howtogeek.com/howto/ubuntu/install-kde-kubuntu-on-ubuntu/ . You will probably see that your xorg.conf file was backed up to xorg.conf.1 during the ?KDE / Kubuntu installation. Just copy the xorg.conf.1 back to xorg.conf, reboot, and everything should be fine. I also tried to do that by booting into recovery mode and then droping onto the shell. But it would not let me rename, came up with some error.

• Notebook overheating

  - by user71372

  I'm asking this question because I've tried many tips to solve they don't work and it sounds like a non-fixed bug ubuntu. My problem is with overheating. I've recently installed Ubuntu Precise 12.04 LTS alongside with MS Windows 7 on my notebook Samsung 530U. I'm using both via dual-boot mode. I've no heating problem with MS Win 7 and the fan speed is normal even with long run utilization. However, when booting with Ubuntu and after short time, the PC got very hot and the fan was running at max speed. I installed a tool called Jupiter, I put it in "Power Saving" mode but no result. Now, I avoid using ubuntu because I fear it'll damage my all new notebook. Please can you give me a "FINAL" fix of this problem (lot of answers exist but I don't know the more accurate and efficient one). Thank you in advance.

• Mouse Not Working on Boot

  - by user88043

  I have seen several topics regarding this situation, but none of them truly address my issue (that, or there are no answers that solve the issue.) Upon booting into Ubuntu 12.04.1 x64 my mouse wired USB mouse (Steelseries Sensei if that makes any difference) either doesn't work or stops working immediately after the grub menu, prior to the login screen appearing. The cursor is present, but obviously not reactive to any mouse movement; even the LED on my mouse turns off (or fails to turn on.) The only way I've found to activate the mouse is to restart the computer, and even then it's 50/50 at best as to whether or not the mouse will be powered. This issue has never happened in Windows 7, so the mouse is operating properly on the hardware and connection side. Forgive my ignorance of Ubuntu (and Linux in general), but I was hopeful that someone would have some suggestions, or could at least instruct me on what to check in order to provide any further information for diagnoses.

• Can't boot from liveUSB when trying to install it alongside Windows 7

  - by ali

  I'm very noob at Linux and installing techniques. I want to install 12.04 from bootable usb flash alongside Windows 7 (also tried live CD but not working) but computer is not booting from USB flash or LIVE-CD and boots windows 7 (Acer Aspire 4750g) and of course I have set the BIOS priority in the right way. There is one important point to tell that I have installed Fedora 16 on my laptop successfully and now I have it on my system. When I was trying to install Fedora I got some error and searched about it and got this point that I should delete a .efi file and then installation went right. In this case , what should I do to solve the problem? (I also don't need my Fedora anymore).
