• file error /boot/grub/i386-pc/normal.mod trying to repair boot, live dvd install probleml

  - by user179295

  I have seen that there are a lot of threads about this problem. I had Windows 8 installed on my series 3 samsung i5 computer and I tried to install ubuntu 13.04. This is what I did: Because of the secure boot I can't install ubuntu from the dvd. So I went in the bios and disabled secure boot and enabled ''CSM''. I went out of the bios and windows 8 couldn't boot more. So I follow a guide on this thread ( Installing on a Pre-Installed Windows 8 System (UEFI Supported) ) and on ubuntu I tried to repair the boot by inserting this code in the terminal: sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install boot-repair Then I ran boot-repair and I follow all the steps. Then I reboot the sistem and saw the black screen that says: error: file '/boot/grub/i386-pc/normal mod' not found grub rescure> Now I saw a lot of guides about this problem but I can't understand how to reistall ubuntu trough the live dvd that I used to install it the first time... I put it in the computer but nothing appears.. so what should I do now? I'm a noob on ubuntu and I have read all the things about this grub 2 install and know where the problem comes from but how to start the dvd??

• How to "un-automount" external harddrive?

  - by Timon

  So I dualboot 12.10 and Win7. Both OSs are on the primary SSD while all commonly used data (documents, movies, music, profiles etc) is on a secondary NTFS-formatted HDD. Since I needed the NTFS drive to automatically mount in Ubuntu right at startup, I downloaded ntfs-config and set it to automount my NTFS drive. Problem is, I also accidentally told it to automount my external hard drive (which is also NTFS formatted). When booting up Ubuntu, it now checks for the presence of that drive every single time, which is getting annoying 'cause I don't always have it connected. I've tried un- and reinstalling ntfs-config, telling it to not automount the external HD, but to no avail. Any suggestions?

• Can't boot 12.04 installed alongside Windows 7

  - by PalaceChan

  I realize there are other questions like this one here, but I have visited them and tried several things and nothing is helping. One of them had a suggestion to boot the liveCD, and sudo mount /dev/sda* /mnt and to then chroot and reinstall grub. I did this and it did not help. Then on the Windows side, I downloaded a free version of easyBCD and chose to add a Grub2 Ubuntu 12.04 entry. On restart I saw this entry, but when I click on it it takes me to a Windows failed to boot error, as if it wasn't even trying to boot Ubuntu. I have booted from Ubuntu liveCD once again and have a snapshot of my GParted I ran this bootinfoscript thing from the liveCD, here are my results: It seems grub is on sda. I just want to be able to boot into my Ubuntu on startup.

• Difference between LiveCD, LiveUSB, full-install, and persistence?

  - by Jay

  I am currently running Ubuntu as a guest vm on a Win 7 host via VirtualBox, but I would like to have a portable version of Ubuntu when I am not using my laptop. I am unsure as to the difference between the following: 1)LiveCD with persistence; 2)LiveCD without persistence; 3)LiveUSB with persistence; 4)LiveUSB without persistence; 5)Full-install. I have a USB flash drive (32GB), and I also have empty DVDs lying around. I know that persistence means that data can be saved, but I am unsure as to which option to choose. What is the difference between a LiveUSB and a full-install on a USB thumbdrive and why would I want to pick one over the other? Thanks for any help.

• Grub2 -- Dualboot Ubuntu LTS 12.04 and Windows 7 -- Detects two Windows 7 (loader) entries

  - by DarkIron112

  this is the first question I have ever asked the Ubuntu Community. :D I'm fairly new to Ubuntu, but I understand the basics and know how to navigate the Terminal. I also know how to ask for/research my problems before asking for/ help. I have scoured the internet high and low and learned much of how Grub2 works. But nothing has helped me to solve my problem. My problem is this: I have a computer that has three hard drives. It previously had Windows XP, but I upgraded to Windows 7. I also installed Ubuntu 12.04 LTS (Precise Pangolin). During my installation of Windows 7, there was a failure and I had to restart the installation. Afterwards, I installed Ubuntu. After some trouble removing all traces of the XP OS (Ubuntu auto-detected it, but not Windows 7) I got the two OSes working flawlessly. Or, almost. When booting up, Grub2 used to display Ubuntu, Ubuntu Recovery Mode, Other Versions of Linux, memtest, followed by "Windows 7 (loader) on /dev/sda1" and "Windows 7 (loader) on /dev/sdb1". I eventually removed Recovery Mode, Other Versions, and Memtest. Now, when I run: sudo update-grub I get this print-out: Generating grub.cfg ... Found linux image: /boot/vmlinuz-3.2.0-26-generic Found initrd image: /boot/initrd.img-3.2.0-26-generic Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 I would like to remove "Windows 7 (loader) on /dev/sda1", as it is a broken entry that shouldn't exist, and must have been installed during my first Windows 7 attempt. I cannot find a Windows 7 entry in /etc/grub.d... And I don't know where to look. Here is a layout of my hard drives: /dev/sda1/ (1.82 TiB), NTFS ("Media") /dev/sdb1/ (100 Mib), NTFS ("System Reserved") /dev/sdb2/ (149 GiB), NTFS ("Windows 7") /dev/sdb3/ (149 GiB), Extended (" ") /dev/sdb4/ (145 GiB), ext4 (" ") /dev/sdb5/ (4 GiB), linux-swap (" ") /dev/sdc1/ (488.28 GiB), NTFS ("Downloads") /dev/sdc2/ (488.28 GiB), NTFS ("AltMedia") /dev/sdc3/ (886.45 GiB), NTFS ("Personal") unallocated (2.09 MiB), unallocated What I think has happened: Windows 7 installed first and badly. I installed it again. First, there was Windows XP to guide where the bootloader went to so it was put on /dev/sdb1/. But, the second time no such guide existed so the machine put another bootloader on /dev/sda1/. sda1, by the way, is the only partition on a 2TB drive. No boot record partition appears to exist according to gedit. I'm not sure where Grub2 is getting this information from. But, there it is. Is there anything somebody can do to help me? Or, is there any more information I should add? Thank you, community!

• Ubuntu 11.10 running in windows 7 (wubi) AND on a separate partition

  - by Pareen

  I am in a very strange situation and need some help: I installed Ubuntu 11.10 through Wubi a while back so that I can use it alongside Windows 7. I was running out of space on my disk when trying to install applications. Without understanding how Wubi worked, I partitioned my C drive (creating a new 90 GB partition) in Windows, booted from the Ubuntu 11.10 install/live disk, and used the "something else" option to create a ext4 (setting the mount point to root) and swap space partitions (/sda5 and /sda6). After the install, my computer no longer boots with the previous Wubi menu and is now using the Linux grub. The options I have are /sda2, which boots Windows 7; /sda1, which doesn't do anything and reloads the same menu, and the run Linux options. So I now have Ubuntu running on a separate partition, as well as the original Wubi install. I want to delete the seperate partition and go back to running Ubuntu on Wubi...if I remove the partition will I need the Windows 7 disk to restore the boot loader? I dont have the Windows 7 disk on me so what is the best way to clean this up so I get rid of the seperate partition? -------------------------------------------------UPDATE----------------------------------------------------- ============================================================================================================ thank you so much for your response. Actually, it would be fantastic if I could migrate my Wubi install into the new partition because I had downloaded the AOSP on the Wubi install (as well as other files) and would love to preserve them. If i can do that and work on the new partition with the old files than that would be great, and I can worry about wiping out the partition completely later on i.e. when I have the windows disk or something. Can you tell me how to do this migration?? So when I select the /sda2, it loads up my Windows. If i click on the Linux, it loads up the newly install Linux (my files that were on the Wubi install aren't there) fine. If I click on the /sda1 (SYSTEM_DRIVE... this is what the Wubi was using to boot the menu that let me select Windows 7 or Ubuntu)... it fails and just reloads the original menu. Here is the link to my boot info script http://pastebin.com/dMrY0NL3

• Windows 7 doesn't boot after Ubuntu install

• Trying to format drive fails

  - by david

  since I will be doing an internship for which i need to use Windows software, I have decided to ruin my day trying to remove my Ubuntu 12.04, install Win XP SP3 (since the DualBoot theme from ubuntu suggests to first install Windows and then Ubuntu, for problems with the bootloader if you do it the other way around) and then reinstall Ubuntu 12.04 since I would like to keep using it as my primary operating system, using WinXP exclusively for the internship. Other than that, I would like to have a partition for the data, which can be used by both Ubuntu and Windows. So now, I have used the disk utility run from an ubuntu-live cd to format my drive with Master Boot Record (being conscious of the fact that this way I will lose all my data, which I have saved on an external drive before, and that my Ubuntu won't work anymore afterwards), creating partitions for Windows (NTFS), personal data (FAT, since as far as I know both Ubuntu and Windows can deal with this), a Swap partition for Linux, and one partition for Ubuntu (ext4); trying to install Win XP from cd gives me a blue screen, which stops the setup and telling me to remove all recently installed drives and to run CHKDSK. So I thought, that maybe Windows doesn't like pre-partitioned drives for its installation and thus I need to re-format my hard drive in order to have a completely "new" drive, which I can then, during the Windows-installation, partition in order to create the partitions I need. Trying to do this, though, the disk-utility run from the live-CD gives me this warning: Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy I do not understand why it tells me that the hard-drive is busy, because, as stated above, I am doing all this from a live-CD. Thus, my questions are: How can I resolve the error given by the disk utility? Does it make sense to use four partitions in the way mentioned above? And if not so, which partitions should I create? Can I, theoretically, partition my drive from an Ubuntu live-cd in order to create the partitions I want and to install first Windows and then Ubuntu? Thanks for any help, David

• Cannot boot from SD card/flash drive on Macbook Pro 13" - boot fails after purple screen

  - by user3512567

  It's my first time using Ubuntu and I have run into some problems. I have a 16GB USB Flash drive and 16GB SDHC Card. I would prefer to use the SD card but either will do just fine if it helps with the solution. I Have a 13" Macbook Pro with no hard drive deeming the machine useless without an OS. I thought I could substitute the hard drive for a 16GB SD card with an Ubuntu ISO on it. I would like to plug in my SD card into my Macbook Pro, boot the Ubuntu ISO and do simple things such as use the browser for internet. The Problem: Whenever I boot my Macbook pro with the SD card that has the Ubuntu ISO, it loads at the purple logo screen and does not function. How can I resolve this issue?

• MIT vs. BSD vs. Dual License

  - by ryanve

  My understanding is that: MIT-licensed projects can be used/redistributed in BSD-licensed projects. BSD-licensed projects can be used/redistributed in MIT-licensed projects. The MIT and the BSD 2-clause licenses are essentially identical. BSD 3-clause = BSD 2-clause + the "no endorsement" clause Issuing a dual license allows users to choose from those licenses—not be bound to both. If all of the above is correct, then what is the point of using a dual MIT/BSD license? Even if the BSD refers to the 3-clause version, then can't a user legally choose to only abide by the MIT license? It seems that if you really want the "no endorsement" clause to apply then you have to license it as just BSD (not dual). If you don't care about the "no endorsement" clause, then MIT alone is sufficient and MIT/BSD is redundant. Similarly, since the MIT and BSD licenses are both "GPL-compatible" and can be redistributed in GPL-licensed projects, then dual licensing MIT/GPL also seems redundant.

• Grub doesn't show both Ubuntu installations

  - by jackweirdy

  I have a laptop with Ubuntu 12.04 LTS installed as the main OS. The other day I installed Ubuntu-Studio (version 12.04) into another partition on the machine. The installation went great and when the machine booted, the grub menu popped up and I could see the option for Ubuntu Studio and the vanilla Ubuntu OS'. The problem was that this version of grub, installed by the Studio installer, didn't look great and insisted on putting Studio at the top of the list, and therefore as the main OS to boot. I use the standard Ubuntu more often, so I booted into that and ran sudo grub-install dev/sda. That worked OK and now Ubuntu boots as normal. Only problem is that the Grub menu doesn't show up and doesn't give me a chance to choose the other OS. Running sudo os-prober shows that it can find ubuntu studio, it doesn't give me a chance to boot it. Any ideas as to how I can fix this problem? Cheers in advance. EDIT: followed instructions here and saw the boot menu, but the only boot options present were for the standard installation of Ubuntu.

• Impossible installing Ubuntu 13.04 in UEFI mode with Windows 8 preinstalled

When booting 13.04 installation media EFI mode get to a black screen with Grub version 2.00-l3ubuntu3 version appears after selecting "install" or "try Ubuntu", there appear error messages: - failure reading sector ... from 'cd0' - you need to load the kernel first I have a Dell Vostro 3560 with Windows 8. I have downloaded and burned ubuntu-13.04-desktop-amd64.iso. Hashes checked. I've booted from the dvd with Secure Boot enabled. The same happens when Secure Boot is disable. When booting with Legacy BIOS, installation starts. I tried Ubuntu without installing and looks OK. BUT, I did not follow the installation because in https://help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_mode there appears "if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too.", which is the case in my computer. I have read many similar questions and the corresponding answers from people in this forum, but till now I haven't found a solution. Could someone help me on this subject? Thanks in advance!

• HP ENVY TouchSmart 15t-j000 Quad Edition + custom mSata Plextor M5M 64GB SSD

  - by Akash Ramani

  The ssd did not come along with the laptop, so i bought one myself and physically installed it. I've booted into Ubuntu from a USB drive and my goal is to install / and /home in the SSD. (because most of the actual media exists on the HDD) The only problem is i'm unable to detect the SSD while configuring the partitions. I know the SSD is not the problem because it recognizes in a different laptop. I've followed the instructions shown in https://help.ubuntu.com/community/UEFI but that still doesn't help in identifying the SSD partition. Any help would be appreciated. (p.s: I'm wondering if i have to prepare the SSD through windows or something like that)

• Unable to access ubuntu through windows boot manager

  - by Arvind

  I am having an ASUS K55VM....it came with DOS....to this Windows 7 was installed...now i am planned to add another OS ie Ubuntu...my computer had 4 partitions of 240GB 230GB 230GB and 230GB....i changed this to 5 parts....243GB 230GB 230GB 150GB and an 80GB...i installed Ubuntu 12.04 to the 80GB partition through a USB flash drive....it installed fine...however the problem is during the Boot option in Windows Boot manager when i choose Ubuntu...this what is displayed... Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.Insert your Windows installation disc and restart your computer. 2.Choose your language settings, and then click "Next." 3.Click "Repair your computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr Status: 0xc000000e Info: The selected entry could not be loaded because the application is missing or corrupt. I tried to change the boot option for the OS and made Ubuntu as my first option....It worked...however windows 7 does not show up in GRUB....in this fear i did the following: Restarted my pc changed boot option 1 to windows. Formatted the drive to which Ubuntu was installed(80GB one)through windows. Restarted again. The problem persists....Windows boot manager shows Ubuntu still and when i choose this it gives two lines one like: grub rescue....but my windows 7 is working perfectly fine. Now want a solution to remove Ubuntu from the windows boot option and reinstall completely...

• Error mounting: mount exited with exit code 13

  - by Mike Williamson

  I keep a windows partition on my laptop for the occaisional bit of Photoshop work. A while ago I noticed that Windows had disappeared from my grub boot menu and when I try to mount the windows partion, my system hangs for a bit and then I get this: Unable to mount 105 GB Filesystem Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to calculate free MFT records: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. It seems that chkdsk is a windows command but since I can't boot into windows (since its the windows partition that is the problem) I'm not sure what to do. Here is the output of fdisk to give you the lay of the land: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x98000000 Device Boot Start End Blocks Id System /dev/sda1 1 10199 81923436 83 Linux /dev/sda2 * 10200 22947 102398310 7 HPFS/NTFS /dev/sda3 22948 29164 49938052+ 83 Linux /dev/sda4 29165 30401 9936202+ 5 Extended /dev/sda5 29165 30401 9936171 82 Linux swap / Solaris Any guidance would be appreciated!

• Windows 8 + Ubuntu dualboot problem - ubuntu does not load after windows updates

  - by Michal Biros

  I have installed Windows 8 64-bit and Ubuntu 14.04 64-bit in dualboot with EFI mode. Everything worked great. I could run Ubuntu or Windows without any problems. Only one little issue was that Windows locked NTFS partitions when I shut it down. When I clicked on restart button in Windows and started Ubuntu, partitions mounted successfully. But today ... I opened windows and downloaded all available updates. When I wanted to come back to Ubuntu I noticed that grub did not count down seconds to automatic start. After choosing Ubuntu option manually, the OS did not load. Just black screen with white underscore in the upper left corner. Windows is accessible always without such issues. Last time I solved it by reinstalling ubuntu but I dont want to do it each time windows downloads some updates. Have you ever meet such problem, or do you know how to solve it? EDIT Ubuntu boots, but it won't start. It ends on loading screen.

• Ubuntu 12.04-2 does not install with UEFI

  - by Rodrigo

  I'm in trouble to instal Ubuntu in Insipiron 14z. I've already created this question (that was wrongly marked as duplicated): First question But, the error seems to be with UEFI. If I disable UEFI on BIOS Setup, I can get into installation process of Ubuntu normally. But, I didn't finish the installation process because I think that will screw Windows 8 installation. So my questions is: Ubuntu installation should work with UEFI. So, why it didn't? Knowing that the error is with UEFI. I can forget the errors listed here?

• Windows XP with Ubuntu 14.04 on 2 separate hard drives

  - by maplenet2

  I am new to Ubuntu. I have Windows XP Professional 32-bit on one 300GB IDE hard drive and Ubuntu 14.04 running on another 61GB IDE hard drive, and I cannot get my Windows XP to boot with Grub! When I select Windows XP from the boot menu, Grub just restarts my computer. The computer I have with those two hard drives is a Dell Optiplex GX240, so the hardware is old, and its BIOS won't let me change the boot priority on the two IDE hard drives. What can I do now? Is there a step I missed when installing Ubuntu? Can I edit Grub to boot Windows XP without messing with the BIOS? Do I have to downgrade to an older release of Ubuntu to make it work? I am willing to reinstall Ubuntu, if that's what it takes.

• How to make Windows boot first?

  - by Rani.Shemer

  I want to know how to make Windows the default boot OS in Ubuntu 11.10, how to make Windows boot first on GRUB2, specifically for Windows 7, which is my current version. I know that are some tutorials about this, but it seems that I made a mistake, so I'm asking. Luckily nothing serious happened. I didn't lose my data. The difference between my question and the tutorials is that the tutorials are from older version. Sorry for any disturbs and redundancy of the question. I'll love it better for a GUI app that making easy the boot. P.S: I forgot to say the version of my OS's I am running Windows 7 Home Premium X64 bit Ubuntu 11.10 X64 bit I hope this will make understand better because I now saw it a tutorial that for 64 bit versions Startup-Manager doesn't work.

• After re-installing ubuntu 13.10, stuck at GRUB Rescue, Boot-Repair didn't work!

  - by user205691

  Because i could not get the WiFi login work, i thought i will reinstall ubuntu, with internet connection to have updated drivers for wireless & graphics etc. I have deleted earlier linux partitions usings gparted and re-installed ubuntu 13.10, exactly following the same steps as i did earlier, making a 100GB /home on dev/sda and pointing root to /dev/sdb (SSD) and swap on dev/sda/ . Installing boot on /dev/sdb. But, somehow i think the grub is either corrupted or removed because i am unable to boot the laptop to any OS now. I get the following message: "no such device" xxxxx followed by huge HEX number GRUB rescue when i type ls on Grub rescue prompt, i can see hd0 & hd1, but thats about it. i tried Boot-repair but it is unable to fix the problem. The following log is generated via boot-repair create log: Boot-repair log I am unable to boot into windows or linux at the moment and need help to fix the grub so i can boot !!
