• Cannot boot after installing ubuntu on lenovo x120e

  - by tutysara

  I have installed ubuntu 11.10 on my x120e using amd64 alternate iso image. The installation went fine, but it is having issues while booting after a successful installation, it says - "No Operating System Found". I followed the instruction at - help.ubuntu.com/community/X120e#Installation to purge grub-efi and installed grub-pc, even then I couldn't boot into ubuntu.(got the same "No Operating System Found") This is the file from boot-repair with this setup - http://pastebin.ubuntu.com/926556/ Then I asked in #ubuntu and they suggested me to create a bios-boot partition, I was not very comfortable with the solution they had suggested but gave it a try anyhow. I re-sized my initial partition and made 4 MB free space in the beginning of the partition and had set the flag bios_grub. Re-installed ubuntu 11.10 this time using amd64 desktop iso image file. Installation went fine as before but finally this time also the system didn't boot, it gave the same - "No Operating System Found" message. In BIOS I have the settings as to use both (Legacy and UEFI) and with UEFI tried first. This is the boot-repair file from my latest setup - http://pastebin.ubuntu.com/926761 Any help/suggestions are appreciated.

• Deleted info in Boot folder

  - by user207984

  First off, I'm using Zorin 7 OS. So my Boot folder was too full to install any new updates, I used a tutorial I found somewhere on here to remove the unneeded linux-image files, and must of also deleted the latest one as well. Now when I attempt to boot I get error: no such partition. grub rescue> I used my MultiSystem USB to install (on a separate partition) a different Linux OS (Kali) and no longer get that error, however, it will ONLY give me the option to boot Kali Linux. Here's the biggest new problem though, I used the built in option of hard drive encryption for Zorin 7 when I initially installed it, so now when I attempt to explore it (to get all my saved data which is REALLY important to me), it asks me for password for encryption. However, the password says it in not recognized, and I know it's right, I had to type it in every single day. So I either need a way to restore my Zorin 7 boot files or GRUB or whatever, so I can boot it up... or I need to know how to fix my encryption problem to save all my info.

• Dual Boot Windows 8 and Ubuntu

  - by Nick

  My laptop has two hard drives, one 320GB HDD and a 30GB SSD. I installed Windows 8 on the HDD and Ubuntu on the SSD. However, after I installed Ubuntu, Windows 8 did not appear on the boot list. I tried boot-repair, but this didn't help.Here is the output of my fdisk -l: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6cd9314a Device Boot Start End Blocks Id System /dev/sda1 * 2048 625139711 312568832 7 HPFS/NTFS/exFAT Disk /dev/sdb: 30.0 GB, 30016659456 bytes 255 heads, 63 sectors/track, 3649 cylinders, total 58626288 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6cd93132 Device Boot Start End Blocks Id System /dev/sdb1 * 2048 207126 102539+ 83 Linux /dev/sdb2 208894 58626047 29208577 5 Extended /dev/sdb5 208896 4112383 1951744 82 Linux swap / Solaris /dev/sdb6 4114432 58626047 27255808 83 Linux Disk /dev/mmcblk0: 3965 MB, 3965190144 bytes 49 heads, 48 sectors/track, 3292 cylinders, total 7744512 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009c694 Device Boot Start End Blocks Id System /dev/mmcblk0p1 * 8192 7744511 3868160 b W95 FAT32 I also tried sudo grub-update, but that also did nothing.

• Two Home and Boot partitions after installing Ubuntu 14.04 and Downgrading to Ubuntu 12.04

  - by Jatttt

  I have Ubuntu 12.04 LTS and I am experiencing some problems. I didn't have Ubuntu 12.04 on a drive to install it but I did have Ubuntu 14.04. So I installed it and downloaded Ubuntu 12.04 using Ubuntu 14. Now, I have 2 home partitions and 2 boot partitions. One home and boot is mounted at /media and the other one is /home and /boot. I cannot get rid of /media/HOME and /media/BOOT even using Gparted. How do I get remove them?

• unable to boot from live USB!

  - by ramblinman

  Linux noob here. I was messing around with my new dual-boot (win7 and the latest ubuntu, 12.04 I think?) Long story short, I deleted some partitions that I shouldn't have. When I boot up the machine, I get: error: no such partition. grub rescue _ I know that I could probably fix this by booting from the live USB. But I can't boot from the live USB either! On startup, I can get "boot from drive" options by pressing F12. (This is how I installed Ubuntu in the first place.) But when I select the USB drive, I get this error: error: no such device: [long string of letters and numbers]. grub rescue _ I've searched around for a fix but most threads addressing the first problem suggest booting from live drive. And I can't do that! Any help much appreciated.

• No Windows Option on Boot

  - by Okoning

  I've installed Ubuntu alongside Windows but at first didn't have a boot option menu. So, I installed bootrepair and ran it. This succeeded in granting me a GRUB boot option menu, but Windows isn't on it. Here is the bootrepair report: http://paste.ubuntu.com/8098527 Can anyone tell me what might be wrong? EDIT: I ran sudo fdisk -l and this is the output: Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00023fe0 Device Boot Start End Blocks Id System /dev/sda1 * 2048 960096255 480047104 83 Linux /dev/sda2 960098302 976771071 8336385 5 Extended /dev/sda5 960098304 976771071 8336384 82 Linux swap / Solaris Disk /dev/sdb: 32.0 GB, 32015679488 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62530624 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 * 32 62530623 31265296 c W95 FAT32 (LBA)

• Windows 7 and Ubuntu Boot issue

  - by user115137

  I had the idea to dual boot Win 7 and Ubuntu and what I did was the following: Made a clean install of win 7 using all of my hard drive, next I used the Ubuntu live cd and gparted to partition my drive to be the following: /dev/sda1 ext4 20GB (Linux root) /dev/sda2 ntfs 100GB(Win7) /dev/sda3 ext4 350GB(Home) /dev/sda4 extended 4GB(swap) The thing is, when installing ubuntu I deleted the partition win 7 creates for its boot sector and recovery and then resized the drive to look like what I mentioned, and Ubuntu installed GRUB to the MBR. When GRUB boots I can see Ubuntu but not Windows, how can I chainload it? Or should I fix the windows mbr with the windows 7 installation disk and try to set the dual boot from there? I don't really care which one of the 2 bootloaders I end up using, I just want the dual boot to work out. Thanks

• Can't boot into 12.04, grub menu won't show

  - by Marcus

  I downloaded the Ubuntu 12.04 64bit and installed it on a 115GB partition next to a 15GB swap alongside Windows 7. I'm using a asus g73s. I have 2 drives: one with only Windows (500GB) and another with a partition for (250GB) Windows and (115GBb) the Ubuntu and (15GB) swap partitions. But after the installation, I can't find out how to run Ubuntu. It just run windows. I read that it should show a grub menu. I tried: Holding both Shift keys at boot up. Running the Ubuntu Live CD and edit the grub file. Also pressing the Esc and some function button during boot. Nothing seems to work. I solved my problem. I pressed Esc during boot and a boot menu opened and there i choosed option: P2 and than the grub menu showed.

• Why does Ubuntu 12.04 dual boot fail?

  - by Tranas

  Fresh install of XP followed by a fresh install of Ubuntu 12.04 results in the following error: error: unknown filesystem. grub rescue and the machine will not boot. Prior to the 12.04 install, XP worked fine. During the 12.04 install, all partitions and free space was visible, and the install seemed to complete without issues until the error message. Although I can fix the MBR via recovery console in XP and allow the machine to boot to windows, why is GRUB/Ubuntu trashing the boot sequence?

• Full disk encryption with seperate boot and encrypted keyfile storage: Two-Form Authentication

  - by Cain

  I am trying to setup true Full Disk encryption with two-form authentication on 12.04 and can not find out how to call a keyfile for the encrypted root out of another encrypted partition. All documentation or questions I am finding for whole or full disk encryption only encrypts separate partitions on the same disk. This is not what most are calling full disk encryption, /boot is not on a partition on the root drive, rather it is on a usb stick as sdx1. Instead root is on a logical partition on top of a LUKS container. Luks is run on the whole disk, encrypting the partition table as well. All drives in the machine are completely encrypted and to open it it requires a USB drive (what I have) as well as a passphrase (what I know) resulting in Two-Form Authentication to boot the machine. Device sdx cryptroot vg00 lvroot / There is no passphrase to open the encrypted root device, only a keyfile. That keyfile is kept on the usb drive with /boot, in its own encrypted partition (I'll call this cryptkey). In order for the root file system (cryptroot) to be opened, initramfs must ask for the passphrase to cryptkey on the usb drive, then use the keyfile inside that to open cryproot. I did manage to find what I think is the how-to I used to do this once before: http://wiki.ubuntu.org.cn/UbuntuHelp:FeistyLUKSTwoFormFactor I already have the system installed and can chroot into it, however, I can not get it to call for the keys on the USB during boot. I did find a how-to saying I needed to make a cryptroot conf for initramfs but, I believe that is for a passphrase: https://help.ubuntu.com/community/EncryptedFilesystemLVMHowto#Notes_for_making_it_work_in_Ubuntu_12.04_.22Precise_Pangolin.22_amd64 I also tried to setup crypttab. However, crypttab only works for drives mounted after the root drive as calling for a keyfile on a device not yet mounted to the system doesnt work. The Feisty how-to included scripts that would be run during boot instructing initramfs to mount the usb drive temporarily and call the keyfile for root which worked quite well except those scripts are outdated now, many of the things they relied on have been merged into something else, changed, or simply don't exist anymore. If I have missed a clear how-to for this, that would be wonderful, I just don't think I have.

• Where to install bootloader when installing Ubuntu as secondary OS?

  - by HelpNeeder

  I'm trying to install Ubuntu as secondary OS on my laptop. I have Windows 8 already installed on my laptop. Now, I know how to run Ubuntu from USB drive, I created addition partition and formatted it to EXT4. So I'm ready to install. Now, 'Device for boot loader installation:' displays: /dev/sta ATA HITACHI (750 GB) /dev/sta1 Windows 8 (loader) /dev/sta2 /dev/sta5 /dev/sta6 Ubuntu 12.04 (12.04) /dev/stb I tries choosing Ubuntu 12.04 partition but it doesn't even let me to pick which OS to install and goes straight to Windows 8. Which partition I must choose to be able to pick which OS to boot from? Preferably, set up so Windows 8 will be at first place, and Ubuntu on second. Any ideas? I don't want to mess up anything if I pick something wrong.

• How to I make my bootcamp partition bootable again?

  - by KJFMusic

  I'm having a similar problem as everyone else in this posting. I have 5 partitions. 3 of which I created for my Mac OS Lion installation, Windows 7 installation and a 3rd for storage. Everything was running fine for quite sometime until recently. My Windows 7 installation has suddenly stopped booting. Instead of a start up screen I get: Windows failed to start. A recent hardware or software change might be the cause. File: \BOOT\BCD Status: 0xc000000d Info: An error occurred while attempting to read the boot configuration data Mac OS Lion starts up fine. I'm unable to mount my "Bootcamp" partition nor the "Storage" partition. On top of that "Storage" has been renamed to "disk0s5". When I installed Windows 7 it didn't recognize the "Storage" partition that was created in Lion so it merged what it thought was free diskspace (I'm assuming the same space that Mac OS recognized as Storage) to the Root Drive of Windows 7 (Bootcamp). Are you able to assist?

• Triple boot vista xp ubuntu

  - by Artyom2033

  My partition table is pretty messed up from install/uninstall os and what I want to do now is to clear that and have vista/xp/ubuntu 12.04 on the same hard drive. I have create a new partition for xp on vista, everything was fine, but when I restarted my pc, I was getting the grub restore prompt. Even when I was trying to install xp, when the 'lunch windows' came, a wild BSOD appear. So I have deleted my partition for xp using gParted include in the 12.04 live cd. This haven't resolve the problem and I am still unable to boot in vista nor ubuntu. But I realy what this triple boot for LoL purpose (since my vista installation keep giving latency spike in this game and I hope this will not be the case in a fresh xp installation (I have tested it in ubuntu, the ping was good, but the fps wasn't). So what I want to do, is to install xp on a partition, then be able to boot on any of them without a problem from a nice installation of grub or something. gParted screenshot Thanks for help. Sorry for my English.

• Windows 8 BIOS - Boot Ubuntu from External HDD

  - by F3AR3DLEGEND

  My laptop came pre-loaded with Windows 8 64-bit (only storage device is a 128 GB SSD). Since it is my school laptop/I've heard creating a Linux partition alongside Windows 8 is not very wise I installed Ubuntu onto my external hard drive. I have a 500GB external HDD with the following partitions: Main Partition - NFTS - ~400 GB Extension Partition / - ext2 - ~25gb /home - ext2 - ~30gb swap - ext2 - 10gb /boot - ? - 10gb ? = not sure of partition Using the PenDriveLinux installer, I created a LiveUSB version of Ubuntu 12.04 (LTS) on a 4GB USB drive. Using that, I installed Ubuntu onto the external hard-drive, without any errors (or at least none that I was notified of). Using the BIOS settings, I changed the OS-loading order so that it is in this order: My External USB HDD Windows Boot Loader Some other things Therefore, Ubuntu should load from my hard drive first, but it doesn't. Also, my hard drive is in working condition, and it turns on when BIOS starts (there is a light indicator). When I start my laptop, it goes directly to Windows 8 (I have the fast startup setting disabled as well). So, is there any way for me to set it up so that when my HDD is connected, it will automatically load Ubuntu? Thanks in advance!

• Dual Boot Installation with Win7 - Install Ubuntu in New Partition

  - by RC Russell

  Under Win 7 I created a new 100 GB disk partition (L:) to install Ubuntu 12.04. I then rebooted from the Ubuntu install CD, selected "Install side by side" and now I'm stuck. I end up at the Advanced Partitioning Tool and I do not know how to tell the installer to use the L: partition. Any help would be appreciated. Thanks! Thank you. I have successfully installed Ubuntu 12.04 alongside Win 7. However, now when I reboot the laptop it goes directly to Win 7 with no option to choose Ubuntu. Any thoughts on how to get the boot-time choice to show up? Thanks!

• HDD,CD,DVD - how is sector id distinguishable from data?

  - by b-gen-jack-o-neill

  Hi, as titles says, how is sector id on HDD,CD-ROM and so distinguishable from data? I mean, when I want lets say sector #52, first, head goes to track where this sector should be, than it must wait some time to spin the desired sector above the reading head. But it must somehow recognize that its sector number, and not only data that say 52. So, how is this done? Thanks.

• Ubuntu 10.04 preseed unattended install results in faulty partition table

  - by joschi

  I'm currently trying to set up an unattended installation of Ubuntu 10.04 (Lucid Lynx) through preseeding. But whenever I try to create a custom partition scheme, the Debian installer (which Ubuntu is using) produces a faulty partition table. I've taken the partition scheme described in the example preseed file: d-i partman-auto/expert_recipe string \ boot-root :: \ 40 50 100 ext3 \ $primary{ } $bootable{ } \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ /boot } \ . \ 500 10000 1000000000 ext3 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ / } \ . \ 64 512 300% linux-swap \ method{ swap } format{ } \ . Unfortunately it also produces an incorrect partition table on the disk. The installation process itself is working and the installed system eventually boots and is working, as far as I can tell. But fdisk and cfdisk are still complaining: # fdisk -l /dev/sda Disk /dev/sda: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 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: 0x000a1cdd Device Boot Start End Blocks Id System /dev/sda1 * 1 5 37888 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 5 2089 16736257 5 Extended /dev/sda5 5 2013 16121856 83 Linux /dev/sda6 2013 2089 613376 82 Linux swap / Solaris cfdisk even refuses to start at all: # cfdisk /dev/sda FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder parted on the other hand does not complain about the cylinder boundary of /dev/sda1: # parted /dev/sda p Model: VMware Virtual disk (scsi) Disk /dev/sda: 17.2GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 39.8MB 38.8MB primary ext4 boot 2 40.9MB 17.2GB 17.1GB extended 5 40.9MB 16.5GB 16.5GB logical ext4 6 16.6GB 17.2GB 628MB logical linux-swap(v1) Since the installed system is working, it shouldn't be a big problem but I'm afraid that this will mean trouble in the future.

• 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.

• HP Pavilion dv7 dual boot with ubuntu and original win7 issues

  - by Neasy11

  I just bought a hp dv7 and I want to dual boot it with the win7 it came with and ubuntu 12.04.1. I shrunk the C partition to make room for the ubuntu one then downloaded an burnt the iso. Next I booted from the cd and followed the simple instructions until I got to the page of the install to choose the partition where all choices were greyed out and the table was completely blank and the drop down only had one choice. After researching this I found that a main problem might be that I can only have 4 primary partitions and the computer was shipped with the 4 already (system,C,recovery,hp tools). I guess my question is what is the best way to go about completing this dual boot? I have read to delete the hp tools partition or combine it with another, I just want a step by step of how to dual boot this computer, I have done plenty of computers in the past but never ran into these issues that come with an HP (should have got a dell lol)!

• Dual Boot not recognizing new hard drive

  - by Grove

  I am a complete Linux newb..which will become obvious shortly. The story: I wanted to dual boot with Ubuntu. I already had windows on 1 hard drive (320gb), and I wanted Ubuntu on a 2nd hard drive (2tb). I setup the partitions using the "Something else" option - I left the first hard drive alone, and put a swap and a ext4 partition on the 2nd hard drive. When it asked me where the bootable device was, I put the first hard drive. The problem: Now that Ubuntu is installed and grub lets me pick which os to boot to, I boot to ubuntu JUST FINE. BUT when I go to the home folder and look at devices, the only drive showing is the 320 gb/old hard drive that windows was installed on. I can not see the 2 TB hard drive anywhere. This is strange because I setup the Ubuntu partition to be the 2 TB hard drive and I thought I installed ubunto on that partition. Thank you for your time and patience :)

• Dual boot w/ windows 7

  - by Aduff

  So my PC had windows XP and Win 7 on it and I went into the XP partition and installed Ubuntu 12.10 over it being sure to use 90% of the XP partition for the / mount and 10% for the swap. It installed but when I boot the computer it doesn't give me the option of choosing between 7 or Ubuntu, just booting right to the Linux distro. Should I have installed it in 7 over the XP partition? I can see the drive in Ubuntu that contains all the 7 files. How can I recover my 7 access?
