• Failure to boot after suspending

  - by kosmonavt

  I have two issues with Ubuntu 12.04 (upgraded from 11.04, 11.10) on my ASUS K52De laptop. First issue: Booting fails, if it follows a suspension, then a wake-up and finally a shut down. If I realize this sequence, then, during the boot I see the Asus logo and after that I see only a blinking cursor instead of grub2. Then I have to recover grub2. Second issue: Sometimes, my laptop doesn't shut down. It freezes on the Ubuntu logo and I must turn it down with power buttom. Thank you.

• Ubuntu 12.10 live-usb won't boot

  - by user109175

  I own an Aleutia "Tango" low power PC. It uses a Intel Atom CPU N2800 @1.86GHz processor. I know there are Linux issues with the "Cedar Trail" graphics on this hardware but I can happily run Ubuntu 12.04 using the VESA graphics driver. I wanted to try out Ubuntu 12.10 so I created a live USB under 12.04 but I am unable to get this to boot. It gets as far as the Grub screen but after that the monitor shuts down. I have tried the F6 "nomodeset" option but that doesn't make any difference. Does anyone have any knowledge of this problem? Thanks in advance.

• Boot splash broken by "SP5100 TCO timer: mmio address 0xyyyyyyy already in use"

  - by mogliii

  I have ubuntu 11.04 with all the latest updates. I have an ATI HD 4350 graphics card and the "ATI/AMD proprietary FGLRX graphics driver" activated. The reported behaviour does not affect the functionality, its just an optical thing. When I booted up using the desktop CD, the ubuntu boot splash was shown correctly in high resolution. Now after installation with FGLRX the dipsplay is broken (see picture). http://img824.imageshack.us/img824/7269/tcotimer.jpg This is what can be found in dmesg [ 8.621803] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01 [ 8.621967] SP5100 TCO timer: mmio address 0xfec000f0 already in use [ 8.622650] fglrx: module license 'Proprietary.

[ 8.622656] Disabling lock debugging due to kernel taint This is what MMIO means: https://en.wikipedia.org/wiki/Memory-mapped_I/O Any idea how to get back the high-res splash?

• Quantal analyzes the HD in any boot

  - by Lucio

  I have installed Ubuntu 12.10 formating the HDD. Any time that I turn on the PC and boot Ubuntu, it always analyzes my HDD in search for bad blocks. This is what happens: When I turn on the PC and load Ubuntu, before I can login my user, appears the following image. If I press C, the process ends and I can work, if I wait until the process can finish by itself also I can work. Also I had this problem, related to the HDD. My Hard Disk Driver is a Western Digital. Is there any problem on the system? Can I stop this procedure? Information that can help: tune2fs -l output

• Ubuntu 12.04 LTS - Black Screen at boot After changing Nvidia Driver

  - by nDman

  2 days ego i updated my Ubuntu 12.04 LTS to latest updates but i ignored Grub Updating because I thought it will clear my grub settings (I'm so noob!). After restart every things was right, the Ubuntu started normally and every things was working well except graphic which had problem before update. I had the experimental driver before but I changed it to the current-update version. After restart Ubuntu stock on black screen. I tried to reinstall Nvidia driver from recovery but it not worked. Then i used Update Grub in recovery, it not worked too but i see this line on screen at boot: at this time it stops and keyboard not working, but when I push the power button it shows these lines and it will shutdown. OK finally I made it start with older kernel (3.5.0-28-generic). Now how can I keep this kernel or fix Ubuntu to work with new kernel? Should I reinstall Nvidia driver? Which version should I use?

• G5 quad core will not boot from Ubuntu CD

  - by Steve Howard

  I have a PPC G5 Quad Core with Leopard on one hard drive and I want to install Ubuntu on a second hard drive. The second drive is installed and formatted as a Mac OS Extended (Journaled) drive. I have had no success booting from a CD or DVD with various PPC versions of Ubuntu using any of the suggested keys such as "C, Option, or anything else. Booting into open firmware doesn't work as the system can't find the \install\yaboot file. I am using various CD's burned as iso disk images, but none will boot. I have reset the PRAM, etc, to no avail. Beginning to get very frustrated. Can someone shed some light and provide me with a command line in open firmware that will work, or else direct me to a confirmed PPC bootable version of Ubuntu please? I'd appreciate any help you can provide....

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• Upgrading a dual-boot system HDD

  - by Jason

  I dual-boot my laptop due to lousy VM performance, and have a new 500GB/7200rpm drive coming in to replace the stock 320GB/5400rpm drive. I have the drive set up in three partitions: one for the Win7 system files, one for storage, and the third as the ext4 Linux file system. The system file and storage partitions are both NTFS. What I'm planning to do is use the system image creator built in Win7, then move that over to the new drive. However, how can I migrate the Ubuntu partition, and how do I make sure that the Grub bootloader isn't overwritten by the Windows loader?

  - by Etienne

  I'm having a problem as stated in the title regarding bootup. What happens basically is that after grub is loaded the system doesn't boot.

This has been observed when running kernel 3.5.0-30 and 3.5.0-28. System is an HP6550b. Can someone help me on this please ? Many Thanks!

• Dual boot windows 8.1 acer V3-571G with Ubuntu 13.10

  - by tara512

  I am trying to dual boot my acer which came with windows 8 pre-installed. I tried using the tutorial here doing it the simple way but when I load Ubuntu from my transcended flash drive it says that there is no other operating system installed. I tried partitioning my hard drive but I seem to have 3 recovery partitions and even though I have 485GB free I can only allocate 100GB to the new partition. I would like to have most of my hard drive allocated to Ubuntu and just use the windows for programs like microsoft office.

• After installing Windows XP I can't boot into Ubuntu 12.04 LTS

  - by Osama

  I know that this issue may have been happened to many people and answered many times. For some reason, I had to install Windows XP beside Ubuntu 12.04 LTS. Once I did that, I'm no longer able to log on to my Ubuntu. The booting list screen doesn't show up. I tried some ways to fix that, one was to try Boot Repair (of course after opening Ubuntu live from a USB), however, the program didn't open after the installation had finished !! So how can I fix that? I hope you guys stick a little with my problem until it is solved

• Upgrade from 12.04 to 13.10: Computer won't boot

  - by Christian

  I upgraded from 12.04 to 13.10 and my computer boots to a black screen. I hear the drumroll, but there is no functionality after that. I've downloaded a livecd of 12.04 on my other computer, and I changed the BiOS settings to boot from CD/DVD first, but it still does the same thing. I booted advanced options, edited [ro quick splash] to [ro nomodeset] and it started normally. I rebooted the system and it was back to the same junk. What do I need to do while it is operating to make it reliable with every restart? This seems to be a systemic issues with NUMEROUS Ubuntu upgrades, but I haven't read a solution yet. I need some help, please! Thanks.

• cryptsetup partitions not detected at boot

  - by Luis

  I installed a fresh 12.04 and tried to mimic what I had for 10.04. swap should be encrypted with a urandom key and there's another partition that will contain home and other directories. # cat /etc/crypttab | grep -v '^#' | grep -v '^$' cryptswap /dev/sda5 /dev/urandom swap encriptado /dev/sda6 # grep -e 'cryptswap' -e 'encriptado' /etc/fstab /dev/mapper/cryptswap swap swap defaults 0 0 /dev/mapper/encriptado /encriptado ext4 defaults 0 0 I also apt-get install cryptsetup When I boot, the system says (try to translate) that either the partition is not found or is not ready. I should wait, press M for manual or S to jump over. What am I missing here?

I've tried installing it about 4-5 times and i still can't get it. What can i do to fix it?

• Can't boot - "Waiting for Network Configuration"

  - by user213017

  After an update on 13.10, my PC won't boot Ubuntu any longer. It displays the infamous "Waiting for Network Configuration" message and then hangs. I can go into recovery mode, and choose "Start networking" and then go to a root prompt, and that works fine. Ping works. /etc/network/interfaces contains just the two lines "auto lo" and "iface lo inet loopback". I've double-checked that my network is working, the cable is working (it works on another PC) and the network card seems to indicate a connection. Any suggestions on how to get my PC booted again? Right now I'm limited to a root shell prompt.

• Samsung series 9 np900x4c-a03us Dual boot windows 7

  - by rowntreerob

  how do i get USB install of 12.04 installed? how do i change the BIOS? how do i partition the disk for dual boot? Web instructions for USB ISO bootable image were confusing. Series 9 has new, UEFI compatible BIOS - there is a gotcha involving "fast BIOS Mode" The native windows install included 2 partitions that were hard to get rid of: 21GB NTFS for "Samsung-rec" ... recovery 8GB for Hibernation both of the above were hard to get rid of in windows.

• Ubuntu 12.04 x64 doesn't boot anymore after a power failure

  - by Felix

  I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive?

• Ubuntu doesn't boot after upgrade

  - by Hugtrw

  I updated to 12.10 and the OS will not load. I used the boot repair cd, and the only thing that works is the monodeset option in the kernel and the graphics are terrible, mouse disappears and unity will not load. Ubuntu 12.04 ran great. On a clean install of 12.10 Ubuntu wont even load to install unless under using monodeset. I get left a terminal like screen with just a blinking bar. I'm using a HP Compaq NC6400 Laptop, Ubuntu 32-bit, 2gb ram.

• 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?

• Dual boot (Win 7 & Ubuntu 13.10 clock problem

  - by peter

  I'm a "newbie" to Ubuntu, but I've been wrestling with this problem for several hours and don't seem to be able to solve it: When I set the time in Windows (Indianapolis, Eastern U.S. time zone) and then re-boot to Ubuntu, the computer time goes to Hawaiian time. When the time is set in Ubuntu, and the computer is rebooted to Windows the time is advanced by 5 hours. I've set the time in the BIOS, and it seems to make no difference. I've tried setting the time from "automatic" to "manual", all with the same result. Not a big problem, but it shows some underlying glitch. Could anyone explain?
