  • Broken BURG install after backup/restore

    - by WindowsEscapist
    Long story short: BURG is stuck in text mode and I can't seem to get it back to the eye-candy. I have purged and then re-installed to no avail. I am running 12.04. The long story: I originally installed onto 12.04 using Super-boot-manager (BURG-manager) and then stopped using it in favour of GRUB because I had too many entries. I then had to backup and restore Ubuntu (partition was deleted and re-created) due to unrelated issues. I re-installed GRUB2 and booted into Ubuntu to re-install BURG, but after re-booting it appears to be stuck in text mode (looks exactly like GRUB 1). Any ideas? I know I'm not supposed to be using it on 12.04 (I think) but it worked before, so what's up?

  • How to recover data from NTFS partition that was made into a Swap partition?

    - by Raghav Mehta
    I have extremely important stuff on my windows partition which during the ubuntu 10.10 installation,when it said that I should create something called swap space, I selected it to be a swap space (without even knowing what it actually meant) The Grub2 doesn't show up so I don't get a choice to boot Ubuntu or Windows. I don't get my windows partition as a removable device in Ubuntu either. When I go to disk utility and select the sda2 (i.e.. my windows partition) and click edit partition and select HPFS/NTFS for the type and tick bootable and click OK the small processing sign keep on rotating on the bottom right of the sda2 in the chart and after about 10 to 15 minutes it gives an unknown error and thus, I am still unable to use my windows. I am even worse than a beginner who doesn't know a thing about Ubuntu so please be patient and help me out.

  • Ubuntu boots to black screen after failed upgrade from 12.04 to 12.10

    - by ywx
    This happened when I tried to upgrade from 12.04 to 12.10. I don't know whether the upgrade process had completed downloading and installing packages or whether it was still in progress, but I got a message The application Compiz has closed unexpectedly. At that point, my mouse stopped working so I switched to tty1 by Ctrl+Alt+F1 and rebooted from there. I then found that I could not boot into Ubuntu any more. My screen stayed first purple then black. I went back to tty1 and it said I was running 12.10. I tried some suggestions in this thread on Ubuntuforums: Wubi blank purple screen than blank black screen and this one: How to set NOMODESET and other kernel boot options in grub2 but nothing seemed to work. I can boot Windows as normal. I am using Wubi on Windows7. My laptop is a Lenovo T410i with NVIDA NVS 3100m

  • Why does update-grub not find ubuntu 11.10?

    - by Klaynos
    I've recently installed ubuntu onto my laptop. With the intention of dual booting with windows 7. On installation Grub wasn't loading, the computer continued to boot straight into windows. I loaded a live cd, mounted the installed ubuntu partion (sda6) as /mnt/ and windows boot partition as /mnt/boot Following the second option here: http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7 Through its entirety, so creating a new grub.cfg file. chroot /mnt update-grub Did not find ubuntu, just windows 7 and the windows recovery partition. Thinking this might be a weird quirk that as I was in ubuntu (all be it a live cd) it might not list ubuntu I restarted. Grub loaded but ubuntu was nowhere to be seen. How can I add ubuntu with Grub2? I could have fixed this myself in old grub but I'm pretty much in the dark here. Thanks

  • How to enlarge ubuntu partition

    - by Vineet
    I installed Ubuntu 11.10 recently by making a 5.6GB partition from the Ubiquity installer. I wanted to upgrade to 12.04, so I opened the Update Manager and clicked on 'Update Packages' (I was following this guide) After clicking, it said that there was too little space available. So, I want to enlarge my Ubuntu partition so that there is appropriate space for upgrading. I downloaded Gparted. I read another guide which said my computer won't boot if I resize the Ubuntu partition because '/boot will be misplaced and I will have to repair GRUB2 myself.' So how do I do this easily? Thank you in advance.

  • Can't boot to Ubuntu 11.10 after installation with Windows 7

    - by Tylor
    I just installed Ubuntu 11.10 on a machine with Windows 7 already installed. I want to setup the dualboot environment. I have a block of unallocated disk space at the end of the disk (some blog post suggested to do so). Then I started installing Ubuntu 11.10 on that part of disk. I installed the boot loader to /boot partition and the installation finished successfully. However, after installation, Ubuntu 11.10 doesn't show up on boot menu. Then I searched on Internet and I used EasyBCD to add a grub2 boot to boot menu. After this, the boot entry does show up in the boot menu, however it only boot into some sort of grub console. I tried many times, and it doesn't work. It looks like the boot loader is not properly installed? I only have one 1.5TB disk and the first 800GB is NTFS partition with Windows 7. Does this work?

  • ASUS U24a can't boot without live disk

    - by user98965
    I recently picked up a new ASUS U24a while travelling in asia. I've managed to go through hell with the UEFI setup, and finally now have a working GRUB. However, I can't manage to get past the "Loading initial ramdisk". If I boot the live CD-USB (only in BIOS legacy mode), I get a wonderful, working Ubuntu. I finally managed to get UEFI installed on the hard-drive (no option for legacy BIOS boot, or I'd be there in a flash!), and can boot in UEFI mode into GRUB2. But... I can't manage to get past the "loading initial ramdisk". It appears that the disk drivers are failing (there is no disk activity after this point). Ideas? pastebin from the boot-repair is at: http://paste.ubuntu.com/1290011/ best, -tony

  • Fedora 17 keeps using fedora 16 kernel

    - by MTilsted
    I did run preupgrade to upgrade my Fedora 16(x64) to Fedora 17. And it seemed to work fine. So I got the new gimp 2.8, gcc 4.7.0 and so on. But the system keeps using the old kernel from fc16. Uname -a gives me: Linux localhost.localdomain 3.3.6-3.fc16.x86_64 #1 SMP Wed May 16 21:43:01 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The system downloaded the new kernel, so I got /boot/vmlinuz-3.3.7-1.fc17.x86_64 /boot/System.map-3.3.7-1.fc17.x86_64 /boot/initramfs-3.3.7-1.fc17.x86_64.img /boot/config-3.3.7-1.fc17.x86_64 But the system keeps using the old kernel from fc16.

  • System Rescue CD on multiboot usb not working

    - by darkfeline
    I have a multiboot usb with System Rescue CD and GRUB2 on it. When I try to boot it, it tries to find systemrescuecd/sysrcd.dat, attempts to mount /dev/sr0 and all the partitions on /dev/sda before declaring cannot find systemrescuecd/sysrcd.dat on devices and dumping me onto a primitive shell. The relevant entries in grub.cfg: menuentry "SystemRescueCd 32bit" { linux /systemrescuecd/isolinux/rescuecd rootfs=/systemrescuecd subdir=systemrescuecd dostartx setkmap=us initrd /systemrescuecd/isolinux/initram.igz } menuentry "SystemRescueCd 64bit" { linux /systemrescuecd/isolinux/rescue64 rootfs=/systemrescuecd subdir=systemrescuecd dostartx setkmap=us initrd /systemrescuecd/isolinux/initram.igz } I think the problem is that System Rescue CD cannot see /dev/sdb, which is my usb, but I don't know where to begin to fix it. If it helps, I set up my USB with a utility called MultiSystem, which is like MultiISO for Linux.

  • TTY Resolution in Xubuntu 9.10

    - by Zurahn
    I've exhausted my ability to search through Google for this, so I'm giving it a go here. What I'm trying to do is increase the resolution (or decrease the font size) in the TTY terminals. Xubuntu 9.10 uses GRUB2, and everywhere I can find directs me to edit the /etc/default/grub File in order to add vga=XXX to the GRUB_CMDLINE_LINUX value, and this simply doesn't work. Out of endless fiddling with the file, nothing ever seems to change. On my Netbook running an earlier version, I had success with this command dpkg-reconfigure console-setup But once again it yields no change. Got any ideas?

  • Free space not reclaimed after online resizing ext4 in Ubuntu 9.10

    - by TiansHUo
    My root partition was filling up, with only 500 mbs left, I wanted to resize my root partition from 20 Gb to 40Gb So I resized my partition by using these steps: Using Gparted to resize another partition to give space for the EXT4 Using fdisk, deleting the root partition (on /dev/sda2), and creating it again using the new size resize2fs /dev/sda2 Updating grub2 But now the problem is that although I can boot in my new partition and the new partition shows it is 40Gb, but the free size was still 500mb. So I booted from a LiveCD and checked with e2fsck -p /dev/sda2, it reported clean. So I added the -f flag (force check), still, the drive is full.

  • Device cannot be added on software-raid-1 array on Ubuntu 12.04

    - by George Pligor
    Unfortunately all tutorials I have found online until now on how to setup software-raid-1 are outdated on ubuntu 12.40 My target is to setup it on a system with a secondary disk drive that is already running. Format is not an option! I am trying to follow and adapt from 11.10 to 12.04 the following tutorial: http://www.howtoforge.com/how-to-set-up-software-raid1-on-a-running-lvm-system-incl-grub2-configuration-ubuntu-11.10-p2 On the above tutorial there is a successful command which creates a raid-1 array by setting the first disk drive with the installed system as missing: mdadm --create /dev/md0 --level=1 --raid-disks=2 missing /dev/sdb1 But when the time comes to add the first main drive with the installed system on the raid-array with this command: mdadm --add /dev/md0 /dev/sda1 I receive an error message. The error message says that the device /dev/sda is (which makes sense) busy! Note: hardware raid solution is not available since the system is a laptop with two disk drives! Thank you

  • Grub install fails while installing Ubuntu on RAID

    - by Warren Pena
    I'm trying to install Ubuntu 9.10 using the alternate install CD, but I keep getting stuck. I get through the first few steps of the install process easily enough (telling it what partition to install to, what user ID and password to create, time zone, etc.), but then it suddenly pops up a menu asking me what the next step in the install process is. It has "Install the GRUB boot loader on a hard disk" selected by default. When I select it, it goes to another screen with a progress bar and a label "Installing the 'grub2' package." The progress bar gets to 16%, and then I get returned to the same menu. No matter how many times I try to install grub, the exact same thing happens. I'm trying to install Ubuntu on a two disk RAID-1 array. This is the RAID card I'm using: http://www.siig.com/ViewProduct.aspx?pn=SC-SAER12-S2. Any ideas what may be causing this to happen and how I can fix it? Thanks!

  • Installing Windows XP sp3 into USB 2.0 WD 320Gb Hard Drive

    - by NetKabuki
    I have a HP laptop with support for 3 USB 2.0 ports. I also have a clean 320Gb WD USB 2.0 drive. The HP can boot from USB (Bios options). I used the install disk (XP SP3 bootable) and after a few stutters, was actually able to load up a partition on the 320Gb drive with Windows. I cannot consistently get the system to boot up off the USB drive. I am able to drop Ubuntu on that same WD drive and boot up. I can even get Grub2 on Ubuntu to recognize the Win OS. But booting the Win OS is an impossible task. What can I do differently - if anything?

  • Tips on self-learning boot-time fundamentals (grub, disks, partitions, LVMs, etc)?

    - by Harry
    Is there any good resource which I can use to self-learn all the low-level system administration details on Grub, Grub2, disks, partitioning, LVM, etc? I'm comfortable with system admin tasks post-boot but I lack knowledge about both the fundamentals and actuals of all that happens during boot on a Linux system such as Fedora. Any recommendations on how to setup a testbed on my desktop for learning the above? I may not be able to get another machine / harddisk, so may have to rely on something like VirtualBox. But don't know if there are other (better) options... so asking for tips from those who have self-learned / mastered this track themselves.

  • WinXP keyboard input repeat rate problem

    - by Victor Sorokin
    I have problem similar to http://superuser.com/questions/33981/problems-with-kvm-switch-and-keyboard-repeat-rate-on-windows-xp: When I press and hold some key it's repeated random number of times, after that repeat stops and I need to release key and press it again to make repeat continue. If there's simultaneous sound playback and repeat is stopped, sound's stuck while I hold key with unpleasant drumming as if there's some audio problem. This issue is reproducible in WinXP Safe Mode. On the same config under Linux there's no issue. My config: List item PS/2 Logitech Keyboard USB Mouse MB M3A/H-HDMI WinXP Pro English SP2 with added Russian layout (WinXP loads via GRUB2) Realtek audio drivers for AC97 Thanks for your suggestions J

  • How to create a bootable Ubuntu Linux (10.04) USB installation for Macintosh

    - by vdavidovski
    I tried searching the Internet, but could not find a decent tutorial explaining how to create a bootable Ubuntu Linux (10.04) USB installation that could be run not only on a PC but also on Macs and MacBook Pros. In addition, I tried refit, but ended with "Missing operating system" error. Here is basically the layout of my bootable under PC Ubuntu USB drive (using MBR): Partition 1 (ext3, bootable) - Ubuntu Linux 32 bit, contains also grub2 bootloader. Partition 2 (ext3) - Ubuntu Linux 64 bit. Partition 3 (fat32) - contains data. What would be the best way to enable this drive to boot under Mac OS X? And if refit has to be used, could I simply have one more partition on the USB drive containing it? Thanks!

The problem i am facing is that how to integrate a downloaded source code with some IDE(e.g, Anjuta etc). In simple words i want to know that, what is the best way to start development on some existing source code using an IDE. Lets take the example of GRUB2(v1.97.1). I downloaded the source code and now i want to study/customize/enhance/add new things to this code, so i want all the source files should be visible in a structural/hierarchical way for the ease of development?

  • How do I properly dual boot Ubuntu and Windows 7 on an UEFI system?

    - by S. Robert James
    I have an HP Z210 with Windows 7, which is UEFI based. I'd like to dual boot it to Ubuntu 11.10 with GRUB2, but am having problems due to the UEFI. The install CD goes to the end, but then the machine always boots right into Windows. These problems are apparently documented (here and here), but there's no consensus as to what the simplest solution is. Any recommendations? I want Ubuntu and Windows to both be bootable. (Perhaps if I knew more about UEFI and its system partition, and how it differs from BIOS and MBR, I'd be in a better position. So background answers explaining how UEFI loads up are very appreciated.)

  • Booting CDs/USB devices after installing Windows 8

    - by shoyip
    I recently installed Windows 8 on one of my four primary partitions. I had two partitions for Windows 7 (boot and os), one for the Windows System Recovery Environment and the last for Ubuntu. I was often using Ubuntu, but after the installation of Windows 8 Pro I couldn't boot in it because it needed the reinstallation of GRUB2. So I thought to do it by Terminal in a live cd; but when I tried to boot the Live CD, it booted me Windows 8 Pro. This is a problem of UEFI, Secure Boot or my BIOS? It didn't happen never before now. And if it's a problem of Secure Boot, how to disable it? Thanks in advance, Sho.
