• How to get rid of 'grub rescue'?

  - by SaM

  While logged into Windows, I deleted a disk partition which was containing Ubuntu. When I restarted my pc, it is showing 'grub rescue' command prompt. How to boot windows now? I no longer require Ubuntu. I have Ubuntu live CD When I tried the following commend: sudo apt-get install lilo the following error is shown: Err http://archive.ubuntu.com/ubuntu/ natty/main lilo i386 1:22.8-10ubuntu1 404 Not Found [IP: 91.189.92.156 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/l/lilo/lilo_22.8-10ubuntu1_i386.deb 404 Not Found [IP: 91.189.92.156 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

• How do I change the color of the screen that is displayed before the login screen?

  - by Jake Newkirk

  How do I change the color that the system displays just before the login screen is displayed? Here is the boot sequence on my machine in the order that things are displayed: The BIOS screen is flashed. A Black screen is displayed for a few seconds. My Plymouth splash screen is displayed. Purple screen is displayed for a few seconds (This is what I want to change). Finally, the login screen is displayed. Please let me know if you require any additional information while addressing this problem and as always, thank you for your time.

• Linux Live CD only works when Windows is in Legacy mode?

  - by Vee

  I have asked a similar question before and no one was able to help me but I think it was because I wasn't phrasing it properly. This is a better restatement of the question. I have Windows 8 and Linux Mint dual booted on my pc. When I tried to boot the Linux from a CD ROM only, it would give me the following error: error: failure reading sector 0x0 from 'hd1' error: you need to load the kernel first. Press any key to continue... The Linux Mint works fine but otherwise, but it gives this error when I try to boot from CD. The boot Linux from CD only worked when I changed the Windows to Legacy mode in the BIOS settings. When I changed it back to UEFI, it would give the same error. Why is this? How can I fix it? I am somewhat new so is there anything else I should know about all of this? NOTE: I changed the Linux into UEFI mode using boot-repair but that still did not solve the problem when I tried to boot from CD ROM.

• Dual-booting Windows 7 and Ubuntu

  - by CFP

  Hello everyone, I've just received my Dell Studio 17 laptop, which comes with Windows 7 x64 preinstalled. I'm having quite a hard time installing ubuntu on it. First of all, here is how I partitioned the drive using GPartEd: |==Dell utility partition==|==Dell Recovery partition==|==Windows 7==|[==Ubuntu==|==Data partition==]| Where [] denotes an extended partition. Here are the steps I completed: I used GParted to create this structure, keeping windows 7 installed I booted ubuntu LiveCD, and installed it on the right partition I let it install grub automatically I rebooted intu ubuntu I went back to windows 7, no problems I then rebooted. Grub was gone. I used Super Grub Disk to restore grub, it didn't work. I tried to boot into ubuntu from supergrubdisk, but grub couldn't fint the boot folder I then reinstalled ubuntu, went through the same steps, but there SGD did boot my ubuntu I reverted to the previous version of grub, and installed it on my hard drive It worked, but trying to boot win7 got me the "No MBR, press Ctrl+Alt+Del to reboot" error I used the windows 7 cd to restore the MBR (the auto wizard didn't work, had to rebuild the mbr from command line Now Ubuntu is gone. 7 works fine I read a lot about this, and realized that many people could simply not boot win7 again after encountering this problem. Now I'd like to restore GRUB, but I really won't go through the hassle of doing a full new cycle of installing/reinstalling everything again. Is there a GRUB guru around, to provide me with a detailed guide to not screwing everything up once again? Thanks a lot!

• How do I create a 12.04 LiveUSB for a non-PAE machine?

  - by DrSkylaser

  I'm trying to create a dual-boot laptop with Ubuntu 12.04 and some flavor of Windows (TBD). To do that, I need to do some work on partitions & install 12.04. To do that, I need to create a bootable USB that will work with my non-PAE-capable CPU. Someone pointed me to a mini.iso that was allegedly non-PAE-friendly, but it gave me the same error as the straightup 12.04 desktop ISO. What version do I actually need? (This isn't going to be a virtual machine--I don't think the laptop has the RAM to handle that happily--so enabling PAE in the virtual machineware doesn't help me.)

• Install Windows XP/7 without a CD drive when the BIOS does not support booting from USB devices

  - by David Pearce

  I have a computer that has a dead CD drive in it and it seriously needs a new installation of Windows (XP is on it now, but Windows 7 does not sound that bad). At first I tried making a bootable USB drive, but it does not look like the BIOS supports booting directly from a USB drive. Is there some sort of boot loader that I can put onto the hard drive first and boot from the USB drive using that? If not, how else can I re-install Windows on the computer? Edit: The only bootable device the computer has it the network with PXE (although I have no idea how to do that) and it's three internal hard drives

• Can't start Windows 7 after cloning HDD

  - by Paul

  Brief description: cloned HDD1 - HDD2 HDD1 partition 1 boots HDD1 partition 2 boots HDD2 partition 1 boots HDD2 partition 2 doesn't boot Windows, but is bootable in general Now verbosely: In all the cases computer is the same. I have two Windows 7 installations on HDD1 - both are booting fine. I choose between them using standard Windows 7 boot loader menu. Technically there are 4 partitions: 100 MB Boot loader partition (active), Windows 7 copy 1 (25 GB), Windows 7 copy 2 (150 GB) and Working partition. All are primary. In past few days I tried to clone the whole HDD1 to HDD2 of the same size (but 2,5 inch form factor) as is using Minitool Partition wizard. Everything has been copied, all files are accessible, no faults in file system structure, even boot loader wasn't damaged and I hadn't to repair it. But I can boot only first installation of Windows 7 (it boots without issues). When I choose the second installation, I get immediately a completely black screen without any texts, cursors and other data. HDD isn't accessed after that. This black screen is sensitive to Ctrl-Alt-Delete which causes computer reboot. I did some experimenting: Installed Windows 7 to that partition - it booted fine. Then I renamed "Windows" to "Windows.old" and copied Windows directory from HDD1 as it was, using Far Manager, and got the same troubles - black screen. (Of course I performed renaming and copying from other copy of Windows). So, it seems that problems are inside this installation of Windows, somewhere in its files.

• Multiple OS's and GRUB chainloading

  - by Kent

  Hi, I want to have multiple OS installations and I have been advised that chain loading using GRUB is a good way to handle this. I have looked at tutorials on the web but I still have some questions before I can start. I want: Windows XP: 20 GB. For running some school stuff and a game which does not work through WINE. Xubuntu 9.04: 85 GB. My main OS. Another Linux distribution: 15 GB . For experimenting and trying Linux distributions out. I will: Wipe and install various distributions quite often on the 15 Use dd to make a copy of my Windows partition after installing it and getting things to work as I like. My experience is that Windows needs to be re-installed maybe once per year to not get bloated and slow. I have been told: To use GRUB chain loading. It will make it easier when kernel upgrades are made in the Linux distributions, as they modify the GRUB boot-menu. To my understanding I need to: (I might very well be mistaken) Install Windows first. Then install Xubuntu and let it write over the MBR with GRUB (I guess this is the default). Get the GRUB on the MBR start Windows XP if I want to (it's done by default), start Xubuntu using the kernel of my choice or defer execution to the boot sector of my other Linux distribution. The actual chain loading will only occur when I want to start my experimental install of Linux. I wonder: Is step 3 above correct and a good way to handle this? Is it also a good way to use chain-loading for both Xubuntu and my experimental Linux installation? How do I get a Linux distribution to install the boot loader it comes with to the boot sector of its partition and not to the MBR? If I can't get it to not touch the MBR. Then I could make a backup of the MBR using dd and then write it back after installing my experimental Linux installation. But then, how would I get the boot loader (lets say GRUB) into the boot sector of the experimental Linux installation? How would it work if said Linux installation gets a new kernel update and needs to update the GRUB menu?

• Tutorial: Linux Boot Camp: How Linux Boots (part 1)

  Booting. Sometimes it seems like it takes forever. What's the computer doing all that time? How do you find out? The Linux boot sequence is surprisingly simple, and the best part is that almost all of it is controlled by shell scripts you can read -- and even edit yourself.

• Sharing Files between Ubuntu 14.04 and Windows 8

  - by Matinn

  I have Ubuntu and Windows 8 installed on one System. I am trying to share files between these two operating systems using an NTFS Partition wich was created by Windows. I don't have trouble accessing the data on this partition from Ubuntu, however if i create a file in Ubuntu, this file doesn't show up when I boot into Windows. Does anyone know how to do this. From what I have read file sharing should work without installing any additional Software, as I am not trying to access the Linux ext4 Partition from Windows.

• Installing 12.10 messed up Xorg

  - by Ghost

  So I finally decided to upgrade from 12.04 and now my ubuntu install has been rendered unusable. I'm getting the "no screens detected" error from xorg in the console, and no mattr how many times I reinstall it xorg keeps throwing the same errors. I already had to do a bunch of hacks like nomodeset just to get to the console, else I would get an infinite tabulator after the purple boot screen. The machine has a 4200HD IGP, I even tried installing fglrx legacy (4xxx series and below are not supported in regular fglrx anymore) which was a subpar driver in 12.04 but in hopes that the machine would at least work, but nope, nothing at all. Anyone had the same problem? how do I fix it? EDIT: just wanted to add that I upgraded to 13.04 and it didn't solve anything, in fact it might have broken things even further.

• Installing along side of Windows 8

  - by Jake

  It appears as though many people are having problems installing Ubuntu along side Windows 8. My problem, however, seems to be sufficiently different to be unique among such problems. I can't get the Ubuntu 12.10 live-USB installer to run. When I boot I get the following four options: Run from this USB Install to disk Check memory (I can't remember the last one) I have tried the top two. Both result in the screen going black briefly then windows 8 booting as per usual. Does anyone know how I may manage to overcome this problem?

• Broken Motherboard Trace

  - by CoffeeBean

  When you're fairly certain that a motherboard trace is broken near the CPU (i.e.: you suspect heatsink / fan was improperly inserted) is it advisable to attempt a repair? I've heard that it can be done using a substance for repairing embedded windshield defoggers. Has anyone had any experience with this?

• Ubuntu not booting from USB on laptop (no optical drive)

  - by Jamie

  I'm using a Kingston 16GB USB, with the Unetbootin program. (I've tried both downloading the installation iso manually and adding it, or using the program to download.) I've tried creating the bootable USB on an iMac, the laptop and also a desktop. I've booted into the setup of the laptop and changed the boot order to make sure it boots from that drive first. (There is no optical drive so that isn't a problem.) It's an Acer Aspire AS3810TZ. Upon booting it gives this message: SYSLINUX 4.03 2010-10-22 EDD Copyright (C) 1994-2010 H. Peter Anvin et al I get this no matter how I create the USB, it just sits there. I left the laptop for an hour and it hadn't moved. I've also tried on a different 4GB USB (Generic) and that did the same.

• How can I successfully install Ubuntu 12.10 next to windows 7

  - by Ian

  I have an installation of Windows 7 and I would like to install Ubuntu 12.10 side by side. During the installation of Ubuntu GRUB comes up with an error and gives me the option to select which disk it should be installed to. I have always found this difficult as I am never sure which disk to select. In my case I see one with "Windows bootloader". I was guessing that was the boot disk for my system but having selected it and completing the Ubuntu installation, GRUB did not appear and Windows loaded. I had no way to get to my Ubuntu installation. I then tried another disk for GRUB after receiving the same message on a re-install of Ubuntu but it didn't work either. In stead of fumbling about I thought I would ask here. Thanks for any advice!

• Ubuntu gets slower by the day

  - by Doug

  Ive noticed that Ubuntu has been getting slower and slower to boot, launch programs, etc. I installed 12.04 about 4 months ago,now 12.10, running on a quad-core Q8300 Intel, 4GB Ram, and an 80GB WD IDE drive. For some reason (ever since 11.04), Ive noticed after installation, the speed is good. The longer I have the OS installed, every bootup gets slower and slower, launching programs get slower, frame rates change radically(onboard GF9400 gets anywhere from 60fps down to 12 in worst cases). I would think maybe the HD is the issue, however I installed 11.10 on a 160GB SATA, and the same thing occurred. Looking at system resources, I'm holding steady at 1GB memory usage (I have 4GB, but it's actually showing 3.6GB, dunno why), no swap usage, and using right around 4% on cpu currently. HD capacity is only 28% used. Has anyone else ran into this issue? I love Ubuntu to death, but using other distros other than Ubuntu, I dont have this problem.

• Laptop GPU apparently blew up, motherboard doesn't even turn on its power LED. [But..]

  - by leladax

  If I take out the GPU, the motherboard LED turns on but then [if it attempts to power up and boot] it turns off after 2 seconds [fans turn on normally in that short period]. [Without the GPUs out there's not even an attempt to boot.] It's an SLI motherboard for a toshiba (model X200-219). If I take out one of the GPUs (they are on top of each other) it surprisingly lets the motherboard turn on too (as it is if both are out) but it still turns off after 2-3 seconds, same behavior. I wonder if it's the GPU that produces the 'turn off after being on' behavior and not something else. [Has anyone seen this behavior with blown up GPUs or could it be something else?]

• Why dd is not a reliable command to write bootable .iso files to USB thumb drive?

  - by Samik

  As the answers here indicate Ubuntu .iso s are not expected to boot if copied with dd to a USB thumb drive. Now my question is why is so that some Linux distributions have the option to directly write their bootable .iso file to a thumb drive with dd but some (read Ubuntu) have not(for Ubuntu I think it has to be converted to .img first). Is it for some architectural difference in .isos? Or is it due to any limitation of dd itself?I don't know if it is off-topic here. I can move it to a more proper place if the community thinks so or suggests one. Some explanation would be appreciable.

• Ubuntu doesn't start and I can't login

  - by Meph00

  My ubuntu 13.04 doesn't boot anymore. Eternal black screen. If I press ALT+CTRL+F1 I see that it's stucked on "Checking battery state [OK]." I'd like to try to go with sudo apt-get install gdm but I can't login on terminal tty2, tty3 etc. They correctly ask for my nickname, then they make me wait a lot, ask for password and make me wait again. After a lot of time (... a lot) the best I could achieve was visualizing "Documentantion https://help.ubuntu.com". I can never reach the point where I can give commands. Plus, during the long pauses, every 2 minutes it gives a messagge like this: INFO: task XXX blocked for more than 120 seconds. Any suggestion? Sorry for my bad english and thanks everyone for the attention.

• Help installing?

  - by Meghan Dempsey

  I'm having a really big problem with installing Ubuntu on my computer. It seems that when I try to install from BIOS from the CD, nothing happens, and when I say nothing happens it boots up my computer like usual. When I try to install from the CD from My Computer directly from the wubi.exe file, nothing happens. THEN when I try to install from the boot helper, it gives me this error: An error occurred: Could not retrieve the required installation files For more information please see the log file: c:\users\Meghan\appdata\local\temp\wubi-14.04-rev286.log Will it help if I say I have a pirated version of Windows? Maybe that's why? I'm frustrated, and I'm not sure what to do. Please help me

• Update Grub on Squeeze - Kernel downgrade due VMware Server

  - by vodoo_boot

  I happen to run into various problems regarding grub and kernels. I don't really care about the kernel internas. All I want is VMware server in that dedicated root-server. 1.) What is a bzImage vs. vmlinuz? kaze:~# ls /boot/ System.map-2.6.32-5-amd64 bzImage-2.6.33.2 config-2.6.33.2 initrd.img-2.6.32-5-amd64 System.map-2.6.33.2 bzImage-2.6.35.6 config-2.6.35.6 vmlinuz-2.6.32-5-amd64 System.map-2.6.35.6 config-2.6.32-5-amd64 grub I updated my menu.lst (grub2): timeout 5 default 0 fallback 1 title 2.6.32.5 kernel (hd0,1)/boot/vmlinuz-2.6.32-5-amd64 root=/dev/sda2 panic=60 noapic acpi=off title 2.6.35.6 kernel (hd0,1)/boot//bzImage-2.6.35.6 root=/dev/sda2 panic=60 noapic acpi=off title 2.6.32.3 kernel (hd0,1)/boot//bzImage-2.6.33.2 root=/dev/sda2 panic=60 noapic acpi=off That doesn't do well... I think the vmlinuz file is missing initrd or so. Dunno. In fact I don't give too much about kernel boot voodoo as long as it works. update-grub(2) does not work. Does anybody know what magical trick there is to get the 2.6.32-5 booting? 2.) I thought t follow the Deban wiki.. I cannot get header-files for the installed 35.6 or 33.2 kernel in the repositories. I cannot build foreign headers because they will not match the running kernel. So how does one deal with that situtation? I'd prefer not to have to downgrade the kernel. Thanks for any answers!
