  • Create option to load Ubuntu or Windows 7 at start-up

    - by AXK
    We have a new Dell Optiplex 790 desktop with Windows 7 and just installed Ubuntu 12.04 on it using a USB stick that was configured as a boot drive. We created a new partition for Ubuntu during installation using the partition editor that comes up during installation. Everything seems to have gone fine with the installation except that, unexpectedly, there is no option to boot up Ubuntu when the computer is started. We just start the computer and Windows starts up with no option to ever start Ubuntu. The only way we have gotten Ubuntu to start is by putting the USB stick used for installation back into the computer and having the computer boot from it. Then GRUB shows up and the Ubuntu OS that we installed starts up (rather than the live-CD version on the USB stick). Previous times we have installed Ubuntu, GRUB shows up when we start the computer and we can choose among the various OSes installed. Can anyone suggest what to do? We want to have the option to launch either Windows 7 or Ubuntu 12.04 when we start the computer, with the default being Windows 7. Right now there is no option and Windows 7 just starts the way it did before we installed Ubuntu. Note that if we hit F1 soon after starting the computer, we get some sort of Windows bootloader (not sure of exact name) but there is no option for Ubuntu; just Windows 7. Also note that if we hit the shift key soon after starting the computer, as some help pages have suggested, nothing happens (Windows 7 is loaded as usual). Thanks in advance!

  • Dell M4600 with nVidia Quadro 2000M hangs on boot when external monitor is connected

    - by vladeta
    I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

  • Installing linux on OCZ RevoDrive3 x2

    - by user2101712
    First of all, here is the configuration of my computer: Motherboard: Asus H87Plus RAM: Corsair Vengeance 32GB Processor: Intel i7 4770 Drive: OCZ RevoDrive 3 x2 (240 GB) (OCZ Revodrive3 is a PCIe module) I am trying to install the latest version of Ubuntu Desktop (13.10). The problem is that in the UEFI (bios) the drive shows up as a 240 GB drive, but in the Ubuntu installer it shows up as two 120 GB drives. If I install Ubuntu in any of these two drives, it never boots. The screen flickers a few times and comes back to the UEFI menu. I have tried reading up and have come across information that the drive has a "fakeraid", and the solution is to use dmraid. However, when I give the following commands in the terminal (from live CD): # modprobe dm_mod # dmraid -ay it says: no raid disks. And the following command: # ls -la /dev/mapper/ just shows /dev/mapper/control How can I install Ubuntu on my computer? what is the correct method?

  • Computer Freezes After GRUB

    - by paulmcg421
    Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

  • All files gone after running fsck. How can I recover my files?

    - by cinlung
    I am a newbie in Linux. So this is my story I installed Ubuntu server 10.04lts. It worked great for many months, until today i decided to run fsck on the system partition and although it warned me, I kept pressing yes and now it will only boot into grub prompt. So i read some article and tried grub reinstall. But before performing grub reinstall, i decided to run fsck again from Ubuntu 10.04 lts for desktop live CD. The fsck painfully passes, now my drive is recognized as ext4 system and I am able to mount it again. However, all i can see is just boot directory and lost&found. I tried to perform grub reinstalling by doing grup-install stuff, now my grub is still not loading right, my files are missing, and the weird thing is that the amount I found used by boot and lost n found is only 5gb and the amount used in he hdd is 8 gb. So my files must be somewhere in the hdd. Is there any sinple way maybe a windows tool or something yo recover my files? I only need to retrieve my database backup and everything else can go. I am freaking out here. Please help.

    - by user1160163
    So I have 2 hard drives a HDD 320GB and a SSD 20GB.

  • How do you dual boot Windows 7/8 seperatly with GRUB?

    - by Aaron
    I installed the beta version of Windows 8 and re-installed GRUB. When I boot my computer and select Windows 7, I get the new Windows 8 booting screen asking to boot between either Windows 7 or 8. If I choose Windows 7, my computer then restarts and I have to select Windows 7 again in order to boot into 7. But if I choose Windows 8 it boots right up. I understand I can choose which OS to boot by default, but I want my GRUB options to be the only way to choose between OS's. So my question is, how can I set this up so that when I click on Windows 7, I go there, and when I select Windows 8, I boot 8?

  • cannot boot Ubuntu after fresh install

    - by Jonathan
    I just installed Ubuntu on a Lenovo v570, and cannot boot into the system. All I get is a loop, where some (bios) info is displayed, and then the computer asks me where I would like to boot from. I tried reinstalling, reinstalling with a custom partition scheme, and boot -repair after the install. None of these work. I can see the files on my harddisk have been copied. I have installed many Ubuntus in the past, as well other distros where custom partitioning is required. I don't know where to find any useful information since I don't even get too the grub menu. One odd thing I noticed. The bios now had options to boot USB, OpenSuse,Fedora, or the HD. I am not dual booting. I also realized that the boot info is for a network boot, which means the computer is not recognizing what to boot. It is boot an HD problem, because I can install other OSs just fine. I am completely stumped. I would like to settle this, and end up with a tutorial, that explains to me what happened.

  • Restoring Grub after Kubuntu installation

    - by justquestions
    I installed Kubuntu on top of my existing Ubuntu 12.04 (64 bit) installation. During Kubuntu installation, I chose lightdm as my default display manager (instead of kdm). Now after rebooting, the Grub has a new color (gray instead of default purplish) and the screen while booting is gray (instead of purplish). I am curious if it is possible to change this grub behavior without removing Kubuntu. I did find a lot of discussion about modifying grub themes but they were not very useful because I do not know what is the default unity grub theme. I did reinstall grub but it didn't change anything. I tried the Grub Customizer but couldn't succeed. Thanks in advance!

  • How can I customize my bootloader to make it prettier?

    - by Matthew
    I hate how when I turn on the computer it just (after the hp logo, which I hate having also), shows white text on a black background. I'm wondering if there's easy ways to customize this (I'm choosing between Windows 7 and two separate Ubuntu 10.10 installs). I've read a little about some complicated ways to do this, but is there not some simpler ways by installing a package on ubuntu or something? I don't want to hack a bunch of code together to get a simple effect. I'm hoping for actual images and having like the windows 7 logo and ubuntu logo to choose from. Ideas?

  • Partitoning to install Ubuntu but already have 4 main partitions

    I want to install Ubuntu alongside of Windows, but there's a 4 primary partitions limit. So there's: BIOS_RVY (10GB) System (100MB) (Windows) (C:) Windows (D:) Data I'm not sure what to do in this situation. This is my girlfriend's laptop and she doesn't want to remove MSI's pre-installed recovery partition, even though I'm pretty sure she's never used it. What is it exactly? Also, does Grub render Windows's "System" partition redundant?

So my question is, is there a way I can correct this ? Kind of annoying not being able to see the full boot option

Frustratingly, it appears the kernel might be bad (or at least that's what the log below says to me, I could totally be wrong). I'm able to mount the volume to another, working server, chroot the broken volume, and sudo apt-get remove linux-headers-3.MOSTRECENT. Unfortunately though, when I try sudo update-grub, it comes back with /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). What am I missing? Here's the log from the server's attempted bootup: [H[J Booting 'Ubuntu 14.04 LTS, memtest86+' root (hd0) Filesystem type is ext2fs, using whole disk kernel /boot/memtest86+.bin ============= Init TPM Front ================ Tpmfront:Error Unable to read device/vtpm/0/backend-id during tpmfront initialization! error = ENOENT Tpmfront:Info Shutting down tpmfront xc: error: panic: xc_dom_core.c:621: xc_dom_find_loader: no loader found: Invalid kernel xc_dom_parse_image returned -1 close(3) Error 9: Unknown boot failure Press any key to continue... Thanks in advance!

  • How do I uninstall GRUB?

    - by ændrük
    A hard drive that I use only for data storage still has GRUB from past Ubuntu installations. How can I remove GRUB from it without harming the rest of the drive's data? Background I occasionally move the data drive between computers with various boot order configurations, so I would like it to be non-bootable in order to avoid having to accommodate it in each computer's BIOS settings. When I power on a computer while only the data drive is attached, the following appears: error: no such device: fdf38dd4-9e9d-479d-b830-2a6989958503. grub rescue> I can confirm from old backups of /etc/fstab that this was the UUID of a root partition that I recently reformatted and which no longer exists. Here's the the data drive's partition table and raw master boot record. Please note that I'm not interested in workarounds that don't answer my primary question. I can think of several ways to work around this issue, but it bothers me on principle that I don't know how to directly resolve it. Every installation procedure should have a counterpart uninstallation procedure.

  • Ubuntu 12.04 LTS - Black Screen at boot After changing Nvidia Driver

    - by nDman
    2 days ego i updated my Ubuntu 12.04 LTS to latest updates but i ignored Grub Updating because I thought it will clear my grub settings (I'm so noob!). After restart every things was right, the Ubuntu started normally and every things was working well except graphic which had problem before update. I had the experimental driver before but I changed it to the current-update version. After restart Ubuntu stock on black screen. I tried to reinstall Nvidia driver from recovery but it not worked. Then i used Update Grub in recovery, it not worked too but i see this line on screen at boot: at this time it stops and keyboard not working, but when I push the power button it shows these lines and it will shutdown. OK finally I made it start with older kernel (3.5.0-28-generic). Now how can I keep this kernel or fix Ubuntu to work with new kernel? Should I reinstall Nvidia driver? Which version should I use?
