• Dual boot - 12.04 installed first

  - by graeme

  I have found many guides with how to install windows and ubuntu in dual boot mode, but none from the perspective of a Ubuntu user. Unfortunately Wine or OpenOffice do not display a document that I am working on properly so I am forced to getting windows back temporarily. Can anyone give me some guidance on how to go about this, sorry but step by step instructions are needed as I am still fairly new to Linux

• Can't install Dual Boot from USB live - crash and nouvea problem

  - by user215064

  I just got a new laptop with Windows 8 pre-installed and I'm trying to make a dual boot with Ubuntu on my other hard drive but I can't make the Live USB work. I followed all the procedure for disabling the Security Boot and the UEFI setting but still doesn't work. It seems to start the installing procedure but I never get to choose anything: after a few seconds the screen turns black with an error message [18.707838] divide error: 0000 [#1] SMP (it goes on for several lines quoting some nouveau problem). Any ideas?

• Dual-boot: Can't select Windows at boot

  - by user88561

  I have a computer with 2 operating systems dual booted: One is Windows 7 and the other is Ubuntu. In the bootloader configuration, I removed an option stating time to select OS and I also set the default Operating System to Ubuntu. Now the bootloader is effectively proceeding into auto loading Ubuntu, while skipping itself. My problem is that I can not access my Windows 7 Operating System. Could someone give me a clue as to what to do?

• Need Help with partitions and such Dual Booting 13.10 w/ windows 7

  - by Aymax

  so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.

• Dual boot Ubuntu and Windows 7, I Can only boot ubuntu through recovery mode

  - by Alec

  I want to become a new user of Ubuntu, however this problem is preventing me. I have/had Window 7 professional on my computer. I recently looked into getting linux. I discovered dual-booting and decided to give it a try. First I created a bootable flash drive with ubuntu 12.10 64 bit. I then followed the instructions on: https://help.ubuntu.com/community/WindowsDualBoot after I finished going through the setup, my computer rebooted. After the reboot I was able to select Ubuntu, advanced options for Ubuntu, 2 memory tests, and windows 7 (loader). So I chose Windows ( honestly i was more concerned that i still had everything on windows at this point). I then rebooted again and selected Ubuntu. When i selected Ubuntu, the background screen of Grub (the crimson/burgandy color) stayed for a few seconds then the screen went black: video here http://www.youtube.com/watch?v=6kKcG4sT7Lg&feature=plcp I tried again with the same results. so i redid the ubuntu install differently using http://www.liberiangeek.net/2012/10/dual-booting-windows-7-and-ubuntu-12-10-quantal-quetzal/. After rebooting the same thing happened. After that i was stumped, so i figured it could hurt to experiment. after all i backed up my windows 7 stuff, and i have the software disk. I tried booting in recovery mode under "advanced options for Ubuntu" and sure enough, after selecting continue to normal reboot it worked. So i updated and everything but when i rebooted it still wouldn't boot under Ubuntu. It would always boot after recovery mode. So i try installing 12.10 32 bit Ubuntu. the same problem keeps happening. I can still get to Ubuntu through recovery mode. so i went online and tried using the terminal (in ubuntu that i booted through recovery mode) when i was using it i discovered that "Error in sitecustomize; set PYTHONVERBOSE for traceback: EOFError: EOF read where not expected" kept showing up. also i noticed a notification in the top right corner that looked like a do not enter sign. it said "an error occured, please run package manager from the right-click menu or apt-get in a terminal to see what is wrong. the error message was: 'ror in sitecustomize;set PYTHONVERBOSE for traceback: EOFError: EOF read where not expected traceback (most recent called last): File "/usr/bin/lsb_release EOFError: EOF read where not expected 39;0' this usually means that your installed packages have unmet dependencies" Naturally i assumed this was what was causing my boot problems. I downloaded synaptic and updated everything and the error went away. but my boot problem was still a problem. so i go online find some things that have worked for others, like this Try to do this (in your terminal: sudo nano /etc/default/grub Look for: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" Change it too : GRUB_CMDLINE_LINUX_DEFAULT="quiet" And update Grub: sudo update-grub This should fix stuff.) I did this and i still have the problem. sorry for the excessive explanation, please help.

• Problem in VS2010 IDE in analog monitor in a dual-monitor setup

  - by Samik R.

  I am using VS2010 Premium with a dual-window setup. One of the monitors is on a digital (DVI) cable and other one is on an analog (VGA) cable. I have noticed that when I put VS2010 in the analog monitor, there are garbled texts and refresh problems while coding and/or scrolling. This does not seem to be the case when I put VS2010 in the digital monitor. Note that, I am not expanding VS IDE to use 2 screens, just making it 1 full screen, either analog or digital. Has anyone else experienced this problem? I also work with VS2008 and have not seen this problem in either screen. VS IDE has started using WPF from the 2010 release, not sure if this has something to do with it.

• External monitor problems with Asus UX32VD in 12.04

  - by rsilva

  I've posted this video where I show one of the problems I'm facing with my UX32VD in regard of external monitors. As you can see as soon as I plugged the external monitor the laptop screen goes black and the external monitor displays a single color (color changes between red, green and blue). However this does not always happen. For instance if I reboot the laptop with the external monitor already plugged in I get to use it but not the laptop screen. In the Displays settings the laptop screen it's not even listed. Other times it just works. The to screens, without any problems. I tried with other to different external monitor and all this apparently random issues repeat, I even tried using HDMI cable instead. Same random behavior. This question seams to cover one of this issues however the answer did not helped me. I was forced to use the 3.5.2 kernel in order to use the Intel graphics card else the Gallium something was used. Also I've Bumblebee installed.

• How do I know if I am running Wubi or a proper dual-boot?

  - by Don

  I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key. However, I simply could not get the laptop to boot off the USB despite the fact that I made the appropriate changes to the boot device order in the BIOS. So I then turned to Wubi, and (to cut a long story short) it seems I now have a proper dual-boot setup, because I don't need to launch Ubuntu from windows. When I start the laptop, I get that screen that asks me whether I want to run Windows or Ubuntu. However, I'm still not sure if this is a proper dual-boot setup, because when I run windows, it seems that my C: and D: drives are still the same size. If it was a proper dual boot I'd expect separate partitions to have been created for Ubuntu which would have removed some space from the C: and D: drive sizes displayed in Windows. Is there some way that I can confirm whether I'm running a proper dual-boot, and if not, is there some process for converting a Wubi installation to a proper dual-boot?

• Clear Complete Instructions to Dual-Boot 12.04 on OSX Lion

  - by BCZ

  Honestly, google-surfing this question leads to so many half-answers and multi-part communications that it is both scary and frustrating to try to navigate them. The question here is simple: What are the clear and complete step-by-step instructions that you used to dual-boot 12.04 on your OSX Lion (entrapped) Apple computer. Did you use rEFIt, rEFIind, a special .iso of 12.04? What? Obviously, there is a preference for safer, easier, and more reversible methods. I can probably assure that the best answer will get plenty of views.

• Sustaining Dual Channel among many RAM modules

  - by Odys

  I'd like to know what are the factors that need to be set in order to sustain the Dual Channel mode. In a mobo with 4 DDR3 slots: Do I have to put pair of chips? Eg: If I put 3 identical chips only, will I have Dual channel or not? If I put 4 Ram chips that aren't from of same ventor/model, will I have the same latency among them (the highest of all)? Also, will I sustain Dual Channel mode? If one Ram has max frequency of 1033 and the other 3 chips are of 1300, will I have 1033Mhz for all chips and Dual Channel mode on? What if I put 2x4Gb and 2x8Gb chips (latency, Dual Channel)? Can I put 4Gb chips in slots 1 and 3 and 8Gb in slots 2 and 4 and still have dual channel mode enabled? (Some of the questions might sound silly but their answers aren't that clear to me) (Also, assume that there aren't any bottlenecks because of other parts on the system)

  I have dual Ubuntu 12.04 and Windows 7 installed in my PC. I installed Ubuntu after Windows, and I have issues with GRUB. After installing Ubuntu, there was no boot loader in the start up, with an error message about missing OS.

I tried to fix the Windows start up with my Windows Live CD, but that removed the GRUB. What should I do in this case?

  - by Rini

  I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio s series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. There is only one partition which corresponds to windows 7 but I don't know whether the Ubuntu is still there or probably corrupted. So, how to repair it or again install ubuntu ? Please suggest what I should do now? Thanks in advance. R Shukla

• No dual boot option, no boot priority order

  - by Atul

  I installed Ubuntu yesterday. I partitioned my C: when it was asked to give memory allocation to Ubuntu. The version is 12.04. I was able to install Ubuntu completely: Ubuntu is successfully installed. Restart you computer. I restarted and there was no Ubuntu option. Windows 7 also asked for a boot repair. So I did that too. I then wanted to change my boot priority order to Ubuntu but couldn't find it in BIOS section. I allotted 20GB to Ubuntu and it is deducted from C: but I couldn't see the partitioned drive in Windows 7. Wubi was working fine before on PC with dual boot option. I used Linux Live key creator to boot my PC through pen drive.

• Reinstalling GRUB2 on Ubuntu 12.04 | Windows 7 dual boot after Windows reinstallation

  - by Shasteriskt

  So I had the perfect Ubuntu 12 / Windows 7 dual boot set-up -- until I had to re-install Windows 7. After the deed, GRUB2 was of course wiped out, thus my Ubuntu installation is rendered inaccessible. I have tried these steps: mount /dev/sda5 /mnt #This is where my Ubuntu installation resides. mount /dev/sda1 /mnt/boot #Indicated by the `*` under `Boot` when doing `fdisk -l` mount --bind /mnt/proc /proc mount --bind /mnt/sys /sys mount --bind /mnt/dev /dev sudo chroot mnt sudo grub-install /dev/sda sudo update-grub #Then unmounted everything... Unfortunately, only my Windows 7 has been detected and the Ubuntu entries never appeared in the prompt. Only my Windows 7 installation (/dev/sda1) is available in the GRUB2 menu. How can I rectify this?

• Windows7 Gone after Ubuntu dual boot install

  - by Adi

  I had a very hard time to dual boot install Ubuntu 12.04 Apparently, Ubuntu has restriction of 4 partitions and I already had 4, so it just couldn't recognise my partitions. This was something I realised too late, but finally got to install Ubuntu. Now, even though Windows 7 option is listed when I try to boot my laptop, it doesn't really let me boot and just loops back to begin. I tried windows repair DVD also, didn't work. I was fine with complete fresh install of windows too, but Windows CD didn't detect my Hard Disk Drive or any partitions (even though the original C drive with Windows is still an NTFS partition, according to gParted, and I can access the data from same using Ubuntu log in). My Ubuntu works fine, but I need windows log in also. Any suggestions anyone?

• Dual booting Ubuntu 12.04: UEFI and Legacy

  - by cmhughes

  I'm trying to dual boot Ubuntu 12.04 (or 12.10) with Windows 8 on a new Sony Vaio, but have run into some problems :) Specifically, my problems seem to come from choosing UEFI or Legacy as the Bootmode in the BIOS. Here is what I have found so far: Windows 8 needs to boot using UEFI, and doesn't work in Legacy mode Ubuntu (both 12.04 and 12.10) needs to boot using Legacy, and won't boot (at least from the live disk) in UEFI mode I have been able to boot Ubuntu using a live USB disc, provided that I change the Bootmode to Legacy. I haven't committed to installing it yet, because I don't really understand the consequences. My main concerns are that instead of simply selecting Windows or Ubuntu in Grub, I would also have to change my Bootmode every single time, which seems like a lot more trouble than it should be. So, the question: how can I install Ubuntu 12.04 or 12.10 in UEFI boot mode?

  After a software update for Ubuntu, my dual boot with Fedora will not show Fedora in the start menu. It just boots into Ubuntu and when I hold Shift and boot, it only has Ubuntu in the list.

Done E: Unable to locate package grub-customizer I cannot find any other way to fix this problem. I am a complete newbie to Linux.

  I did it!!! I'm right now writting from Ubuntu 11.10 installed in my MacBook Pro using Dual Boot!!! THe only thing is, how can I now access my Mac folders? From Ubuntu if I try to open Music, Documents or any of those folders related to the Mac user I get the following: [The folder contents could not be displayed. You do not have the permissions necessary to view the contents of "Music"] I can access them if I run Nautilus from root (gksudo nautilus), but I would like to just be able to browse those folders. Thanks!

• No boot loader found - dual booting Windows 8 with Ubuntu 14.04

  - by Sriram

  I have been trying in vain to dual boot my computer with Windows 8 Pro (pre-installed) and Ubuntu 14.04 64-bit. I have been able to successfully install Ubuntu 14.04, but the option to start Ubuntu does not appear on startup. This is after having taken all steps as mentioned in Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported). I even tried the boot repair option and ended up with this error log. My questions are: How do I solve for No boot loaders found in /dev/...? Are there any other recommendations that will help me solve this? Other points that may be important: Booting into Ubuntu from a live USB shows all Ubuntu partitions on the hard drive.

• Dual Booting Windows 8 and Ubuntu 12.10 - thinkpad x230

  - by user110703

  I am having problems getting grub to load Windows 8 properly after installing Ubuntu 12.10 and Windows 8 on a solid state drive. Here's what I did: Fresh install of Windows 8 using USB recovery drive (partitioned SSD for UEFI) -- Tested windows install and it worked fine Built bootable USB with Ubuntu 12.10 64bit and installed Ubuntu -- Used Ubuntu's installer to partition the Windows 8 partition and install there Reboot - try to load windows 8 from grub -- Ubuntu loads correctly; windows load reports various problems with permissions and not being able to find files - I'll update what the actual errors are Tried to fix the boot problem using boot-repair: -- here's the output: http://paste.ubuntu.com/1384522/ So, this is my first time trying to setup a dual boot system and I think that UEFI is the main culprit in getting this to work correctly.

• Dual monitor setup with Intel graphics and Nvidia Geforce GT 425M on 12.04

  - by fo_x86

  I have a Dell XPS L401x and just installed 12.04. I have a mini-display and an HDMI output, and I could hook up two Dell UltraSharp monitors to each port on Windows 7, and get a triple monitor setup. Doing a bit of research, it seems like the mini-display is wired to the integrated graphics card whereas HDMI is hooked up to Nvidia graphics card. I've also installed Bumblebee as it seemed like that was the proper way of installing Nvidia drivers on Ubuntu. At the moment none of my monitors is being recognized by Ubuntu. Is it even possible to have a triple monitor (laptop display + 2 external) setup? Has anyone successfully done this?
