  • Grub loading unknown file system grub rescue

    - by Ashish Kumar
    I am new to Linux. I had Windows 7 installed in my laptop. Yesterday I installed Ubuntu 9.0 from a free CD I got. I choose the option "Install side by side with Windows 7 loader (something like that..)". Everything went fine & I installed Ubuntu. When I restarted, I could easily boot from both Windows 7 & Ubuntu. But later when I booted from Windows 7, I did a disk management by right clicking "my Computer" & choosing the option "Manage". Actually I deleted a drive & added that empty volume in another drive. Now when I start my system it shows the following error: Grub loading Unknown file system grub rescue> I have no clue what to do now. Please help me at urgent. Any solution in layman's language is greatly appreciated. P.S. I want all my files on both Windows 7 & Ubuntu.

  • How to fix 'grub error file not found' when installing 12.04?

    - by Tomasz Grabowski
    i'm trying to install Ubuntu. I don't know if it is important, but i'm trying to install it on external HDD. In the end i have external bootable HDD which only displays: error: file not found grub recovery> From the beginning: I've downloaded ubuntu-12.04-desktop-i386.iso I've used LiLi USB Creator (LinuxLive) to create bootable pendrive from that image I've bootet from it, it works I've clicked "Try ubuntu", it works too. I've used GParted to look over drivers (disks) My primary embedded disk is seen as /dev/sda My attached external disk as /dev/sdb My PenDrive as /dev/sdc I've created partitions on /dev/sdb Fist partition for system (over 200GiB) Second was there already (it's xsf, and i don't want to touch it :P) Third is extended partition, with 1 locital partiton (10GiB) for swap I've started installation i've choose "somethin else" in ... i belive secound screeb then is selected /dev/sdb as boot disk for first partiton of /dev/sdb i set i want ext3 file system, i've check "formattin" checkbox, and mount path set to "/" firs logical partiton set as swap partition After installation finished, i restarted my computer. When i boot from my primary disc it's work ok, my previous operating system - vista - works ok. When i set my BIOS to boot from my external disc, i only get that message: error: file not found grub recovery> I've try to reinstall it, but didn't help... In desperation, i've try to read a bit about that "grub recovery" command-line and experiment a bit... I'm not sure if this has had any point, or if it give you some information (notice, that i don't know what i'm doing :P ) when i've type command: insmod (hd1,1)/boot/grub/linux.mod i've get message: unknown filesystem the same with: insmod (hd1,msdos1)/boot/grub/linux.mod the same with: insmod ext3 but i get no message after command: insmod ext2 ... notice that i really don't know what this command exactly do, but than i thought that maybe if i reinstall ubuntu with ext2 filesystem, it will work. I've done that, but symptoms are the same. I've go back to that Live version of ubuntu, filesystem and basics directories seems to be present on /dev/sdb1 ... i'm completely unfamiliar with GRUB. I'm also don't know which wersion of GRUB it is, i hope there is only one version on ubuntu-12.04-desktop-i386.iso Any help? Thax

  • How long does boot repair take?

    - by Emre
    Reinstalling Ubuntu messed up my boot loader so I I tried to fix it with boot repair. It detected my OSX installation and asked about removing the "separate boot/EFI". It also said my partition was full despite the fact that it wasn't and asked me to remove stuff. I declined both and proceeded. It's been stuck at the "purge and reinstall the GRUB" stage for half an hour. Is this typical, bearing in mind I have a fast SSD and CPU? Is there a better way to re-install grub on a multi-booting UEFI system? Does my pastebin provide any insight?

  • How to repair GRUB from backup?

    - by titusjaka
    I have Windows 8 and Ubuntu 13.04 in dualboot. But the problem was that Windows didn't boot when GRUB is set as primary bootloader in BIOS. When the Windows EFI partition was checked as primary, Windows booted well. Then I decided to fix it and installed Boot-Repair. First of all, I made the backup. Then updated the GRUB. The update was successful. But then Windows and Ubuntu didn't boot at all. I've repaired GRUB using live-USB. Now I can boot Ubuntu, but Windows doesn't boot. How can I restore boot partitions from Boot-Repair backup (.zip file)?

  • Problems installing Ubuntu on a vaio with SSD, GRUB installation failure

    - by Alberto
    I have installed and used Ubuntu in several computers. But now I have a problem that I don't know how to solve. I have a Vaio (Product name: vpcz13c5e), it has a SSD 128gb. I decided to install Ubuntu (12.04, but I have tried older versions as well). Firstly, I tested with live USB, and everything was fine, so I decided go for the complete installation. Then everything went as follows: I chose to use the whole disk (first option, formatting everything). I got a message Executing 'grub-install' /deb/sdb failed. This is a fatal error After clicking ok I got another window with 3 options: the first offers different devices to install the bootloader on (I tried all of them and none works). Second option: Continue without a bootloader. In that case I got You will need to manually install a bootloader in order to start Ubuntu The third option is Cancel the installation. So, I chose Continue without a bootloader. Then I restart the computer (with the Live cd) and in a terminal type sudo fdisk -l but I obtain fdisk: unable to seek on /dev/sda: Invalid argument What can I do? any help will be appreciated.

This is what it says: GNU GRUB version 1.99-21ubuntu3 Minimal bash-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. And nothing happens from there, can you tell what I need to do now? THANKS AGAIN!

  • Strange Grub behavior Series 9

    - by jothebo
    I have got a Samsung Series 9 900x3c with Ubuntu 12.04 on. After installing Ubuntu Grub would not load completely (only parts of the Menu were showing) every time so I launched the Boot repair indicating the use of an UEFI bios. Now Grub always loads completely but I do not seem to be able to launch Ubuntu directly. Instead I have to select Advanced options for Ubuntu and the newest Kernel Version and then the boot starts. Any ideas? Thanks a lot in advance Johannes

  • Grub-Efi wrong resolution

    - by Nikki Kononov
    My question, as it comes from the title, related to grub, but it's a different thing. I re-installed Windows 7 and Ubuntu 12.10 in UEFI mode (before that I was using normal BIOS) and everything went perfectly fine. Both systems load as they should but there is one thing that keeps bothering me. The problem is before I installed both systems in UEFI I used to boot in both system using common grub (non-uefi) and resolution in this grub was correct (which is 1366x768). Right now with grub-efi I have wrong resolution (which is seems to be 640x480). So my question is can can I safely set grub-resolution using grub config files or issue is related to something else? (for instance graphics card). I am using Ubuntu 12.10 Intel HD 3000 + Nvidia GT 540M Optimus (I am using bumblebee) Kernel 3.5.0-19-generic all updates installed! I also added ubuntu x-swat ppa for drivers. Thank you for your help!

  • Choose at GRUB menu whether NVidia driver should be used

    - by RobinJ
    For some games, I need the nvidia-current driver, but when it's enabled, I can't get my work done as it messes up everything. So is there a way I can get two options in my GRUB menu? One wich will load my operating system with the nvidia-current drivers, and one which will use the default non-proprietary one? It seems a bit stupid to me to have 2 Ubuntu installations (one for games, one for the rest). But I can't get my daily work done with the Nvidia drivers enabled as it messes up some applications, randomly freezes the system, etc. But I still want to be able to play some games. If there's a way to just load and unload the nvidia-current driver with a script or something, that would also be welcome.

  • 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.

  • Ubuntu doesn't boot due to GRUB-Problems

    - by Dave
    Users out there, I came here with the spark of a hope, that you could help me. I want to get rid of my old WinXP, because the Game-Support for it seems to slowly expire now... So I took a second drive, just an old empty one I had at hands (ATA-Maxtor 90648D3), plugged of the other drive with WinXP, so that it couldn't be harmed, and started the installationof Ubuntu 12.04. Everything went as it was supposed to, until the end. Normal shutdown after successful installation process. But when I tried to boot my new Ubuntu from the HDD, it said: error: out of disk. grub rescue> So, what to do now? I already tried a lot of things in the terminal, e.g. the update-grub as mentioned on http://opensource-sidh.blogspot.de/2011/06/recover-grub-live-ubuntu-cd-pendrive.html. Everything worked, he didn't complain about a missing data or anything, but at the end of the day he still wasn't able to boot! Next step was to change the etc/default/grub-file, so that it could load the ATA-drivers first, so that there is now problem with my drive. But even this didn't seem to have any effect, I'm still stuck with Ubuntu in the Live-CD-Mode... If there was anybody to help me out there, I would be very glad. Thanks for any support, Dave P.S.: I even tried to fix it with boot-repair, a small tool for Ubuntu, and it created a file with data that could probably help you to help me. You can find it on http://paste.ubuntu.com/1428022/

  • 12.04 LTS boot hangs at "SP5100 TCO timer: mmio address 0xfec000f0 already in use", didn't yesterday

    - by DarkIron112
    Dual-booting Windows 7 and Ubuntu 12.04 LTS. I went to reboot from Win to Ubu, and found a few interesting things. My POST screen is covered in blocks of epileptic colors until I hit GRUB, which continues when I try to boot into Ubuntu. These color blocks don't appear when I use my on-board VGA, so I'll just attribute to that. Grub dimensions are swapped (card vs onboard, probably), but, when interfacing with onboard VGA, the Grub Timeout Counter works and when using my card, it does not (see "[!!!]" below for more information) Booting into Ubuntu directly causes the error: SP5100 TCO timer: mmio address 0xfec000f0 already in use Booting into recovery mode, meanwhile, and then "resuming normal boot" gets me to the desktop without native 1440x900 resolution and graphic drivers can't tell the monitor it's looking at (I assume this is because it's not a full graphic boot, and as it says, some drivers won't run?) [!!!] When I reboot after going into recovery mode, the countdown timer works ONCE, puts me back into default ubuntu boot, and then does not work again until after another recovery-mode boot. Windows 7 can boot perfectly with no issues whatsoever from epilepsy color blocks or driver detection. This makes me wonder /why/ the POST screen can't handle my video card anymore. Amidst all the diagnostics, I opened my case and re-seated the videocard securely, ensuring it wasn't a loose connection-- But this did nothing to help me. Hardware I am running an NVidia GeForce GTX 8800 video card in a PCI slot. I have 4.8GiB memory, an AMD Athlon II Quad-core 640 Processor, on an MSI K9N6GM Series Mobo. Onboard video is an NVidia GeForce MCP61(V/S/P) card. Note: I did not have any of these problems yesterday, and I have been using Ubuntu intensively for a week, though it's been working flawlessly for months. I've recently been using it to mod my Android phone, perhaps I messed something up in the file system?

    While trying to delete an Ubuntu partition from my hdd I accidentally rebooted my computer. (Note: the partition was originally made from an existing partition using paragon.) After that when I tried to start the computer I got the GRUB rescue terminal prompt. I wasn't able to do much from that, but I did manage to boot Ubuntu from a USB drive and to run boot-repair. But now when I try to select Windows 7 from the boot selection menu I get the error 0xc0000225.

  • Must go through Windows Boot Loader to get to Grub

    - by Zach
    I just installed a fresh copy of Precise alongside Windows 7. I have to separate 750GB hard drives; /dev/sda holds the Windows partitions and /dev/sdb holds the Ubuntu partitions. Other than that, these are fresh installs of both Windows 7 and Ubuntu 12.04. Whenever I boot, Grub doesn't load, instead it goes to a black screen with a single blinking (horizontal bar) cursor in the top right corner. However, if I boot, hit escape right as the BIOS/POST screen finishes up, see the Windows Boot Loader and hit escape to make it go back to the BIOS screen. After the BIOS screen, grub shows up and everything functions normally; I can boot into Ubuntu or Win7. I don't want to have to do the Escape, Escape, Wait, Boot trick every time. I have no idea what would be wrong or what information I could give you guys to help diagnose. I have run a sudo update-grub and it found everything normally. I tried adding nomodeset flag in the /etc/default/grub line GRUB_CMDLINE_LINUX_DEFAULT which searching around made me think might work. Thoughts on what I could do to fix this? EDIT: I've tried changing the boot order so that both drives in the BIOS (both are labeled as "Internal HDD") have had a try booting first. I think the problem may be that every time I boot, the BIOS boot order is different... and I have to reset it. It seems to not be stable... but I'm not sure how to go about fixing that either. The machine has both traditional BIOS and UEFI. It came standard in "Legacy" mode; so it is currently set to boot through Legacy mode. I've reinstalled Ubuntu now, and now if I hit escape at the end of the BIOS/POST startup screen, it takes me to GRUB menu. Otherwise it automatically loads Windows. It seems like GRUB is now the acting bootloader, it just doesn't automatically start that unless I ask it to open a bootloader. In my other machines, it has always automatically started at the end of BIOS/POST. EDIT2: Using gparted, I just looked at my partitions, it would seem that my linux-swap partition is currently flagged as the boot partition for my Ubuntu install. I currently only have 2 partitions: one of "ext4" with a mount point of "/" and flag " "; and the "linux-swap" with mount point " " and flag "boot." If I change the boot flag to be on "/," it does not reliably solve the problem. After 10 boots: 2 Booted successfully to GRUB 5 Booted directly to Windows 7 3 booted to the black screen with the cursor and hung there Further research makes me think this is an issue of the BIOS not reliably booting hard drives in the same order or not finding both hard drives. If I ask it to create a "boot menu" sometimes it has 2 entries for "Internal HDD," sometimes 1. Also the list it creates changes order every time I bring it up; so it is not following a consistent boot sequence. Will report back if this is not an issue with GRUB.

  • 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
