Downloaded 64 bit ISO for 13.10.  Whether burned to DVD or on bootable USB it's the same result.  The laptop boots to the GRUB try/install/oem/check menu.  When try or install is chosen the screen changes to the Ubuntu logo with the animated dots below it and then animates for a while. After that the screen goes blank  and stays that way. Attempts to bring up console with alt-f1 don't work.  Modified boot options and removed splash and quiet, watching the boot process I see nothing unusual, until the system apparently starts X and the screen goes and stays blank.  I ran check on the USB stick and it says the Ubuntu system on there checks out.  I've tried turning off UEFI boot, but then neither USB nor DVD boot at all. Secure boot is off (has been the whole time).  So far I'm stuck booting into Windows 8.1 or not at all it seems. Right now it feels like my options are to use Ubuntu from VirtualBox within Windows or just return the computer.  Any thoughts or advice?

I am trying to boot Ubuntu on my computer.  When I boot Ubuntu, it boots to a black screen.  How can I fix this? Table of Contents:

I have an Acer Aspire One netbook with an Intel Atom CPU and 1GB of RAM. I've been using Ubuntu and a few other distros on it with no problem for two years now. I have used both Ubuntu/Lubuntu/Xubuntu 14.04, 14.10, 15.04 and 15.10 flawlessly, with casual distro changes (Arch Linux, openSUSE, Linux Mint, elementaryOS, Debian). No problems at all. But today I decided to move back to Xubuntu, so I grabbed the &quot;mini&quot; installation ISO from ubuntu.com, wiped out the Debian Jessie partition and installed the system there. After the installation was completed, I installed the &quot;xubuntu-core&quot; metapackage and rebooted. But the system got to a &quot;Started Update UTMP about System Runlevel Changes.&quot; message and sits there, with a blinking cursor. I could access other TTYs by pressing Ctrl+Alt+Fx and even startxfce4 (as root), but that issue was really annoying me. So I downloaded a Lubuntu 16.04 ISO from lubuntu.net and went to install it. As I didn't have a DVD or USB drive available, I put it in a backup partition and booted the Lubuntu installation media with GRUB2, using set root=(hd0,msdos4) loopback loop /lubuntu-16.04-desktop-i386.iso linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/lubuntu-16.04-desktop-i386.iso config noprompt noeject initrd (loop)/casper/initrd.lz boot  But it also got stuck in the exact same message. The difference is that now I can't change TTY, but I think it's because it's a live media. Some people suggested it may be a graphics driver problem, but I'm not sure. I also saw a similar problem with some Mageia folks. Can someone help me?

I know this might be a duplicate, but I've read a lot of threads about this and none pointed me to the solution.  When loading GRUB2 I have a black screen (with static white cursor on the upper left) which goes away as soon as the Ubuntu login page comes up, but stays there forever if I boot Windows (even though I can hear the 'login sounds').  I have a dual boot system with Ubuntu 14.04 and Windows 7 (both 64-bit) and I have a NVIDIA VGA. The Windows installation used to work just fine, with the VGA doing its job. My monitor was plugged on the motherboard when I fresh installed 'trusty tahr' (I have a integrated intel graphics CPU) and after that I immediately installed the video card drivers from the official repo (nvidia-331 I believe). Their installation was successful (at least from what I see from the 'Nvidia X serve settings' tool). After that, if I plug the monitor on the video card, grub goes on the black screen, but I can anyway boot Ubuntu and when the login page comes up the video output is normal. The same cannot be told when Windows boot.  I tried many suggested fixes: nouveau.modeset=0, nvidia.modeset=0, nomodeset options in the /etc/default/grub file and I also tried blacklisting the corresponding kernel modules adding a .conf file in /etc/modprobe.d. None of that solved my problem.  I insist that this must be a grub video problem, since if I plug my monitor on the mother board I can boot successfully both Ubuntu and Windows and also the boot-repair tool for Ubuntu doesn't find anything significant (see ).  I'm currently out of ideas, has anyone any suggestion? It would be much appreciated!  Lorenzo

I purchased an Acer Aspire M5-481PT-6688 which came preloaded with Windows 8. I wiped that, reinstalled my own bloatware-free copy, and tried to dual boot Ubuntu 13.04 on it. It has a hybrid drive, so when I installed it running alongside Windows, Ubuntu was installed to the SSD and Windows is on the HHD. I later removed Ubuntu via formatting the SSD and now I'm stuck at the grub rescue&gt; prompt. The error says: no such device. No matter what key combo I press (F2, F8, F10, F12, Esc, Del) I cannot access my BIOS nor can I boot from the CD/DVD drive or USB.

I have been trying to install ubuntu (I tried 12.04LTS, 12.10, 12.10-secure-remix) using the wubi installer on Windows 8 and all the three times ran into the same problem showing some cannot find /ubuntu/winboot/wubildr when I tried to start ubuntu.  I tried to change the boot settings from UEFI to Legacy and then my laptop restarted and showed that "No operating System Found".  I then tried to install Ubuntu using a cd and after a lot of effort and using boot repair,etc. I landed into a new trouble. When I select UEFI on, the laptop loads Windows and windows too does not detect ubuntu. When I select Legacy mode, it starts ubuntu, shows me an option to start windows 8 but gives an error showing windows failed to load.  So in legacy mode, i am able to use only ubuntu and in UEFI mode, I am able to use only Win8. Please explain any process of starting windows in legacy mode (which I tried without any success) or starting ubuntu in UEFI mode.

I am trying to install linux on my laptop, a Toshiba Satellite C6550-S5200. I did it once but something happened so I removed it then I had to destroy all data on hard drive so now I have nothing on it. Well I got a iso file burned to a CD and to a flash drive. With the flash drive I get.   SYSLINUX 4.06 EDD 4.06-pre7 Copyright (C) 1994-2012 H. Peter Anvin et al  With the CD it will start booting it but somewhere loading it up, the dots turn all orange and stay that way and my CD drive turns quiet.  Oh and some more info the images work because I tried loading them up on another pc and it worked just fine.  I manage to get the CD to boot I just had to let me pc boot up first then insert the CD and have it boot the CD then. Once I get done installing ubuntu it works fine but I have to leave the PC on 24/7 for if I turn it off the PC will freeze 5-10 seconds after booting back up no matter how I install it.

First of all: this is not a duplicate of the all the " questions.  Problem:  When booting, the system will not boot unless the installer USB flash drive is present. If I boot without the USB drive, the screen goes black AFTER GRUB lists the different configurations available - so GRUB is on the correct disk, its what it does next that seems to be the problem.  With the USB drive inserted, its access light starts flashing while the system boots in a normal manner.  And yes: I have tried booting from the USB drive directly and then I get the "live" version, so I have not installed the OS on the flash drive by mistake :)   I have tried sudo grub-install /dev/sda and sudo update-grub just for fun, but nothing changed.  System in short:  Ubuntu 12.04 64-bit. i3 processor. UEFI bios. 128Gb SSD drive. The SSD has a 47 Mb EFI partition and the rest mounted as '/' (XFS).

I have been reading about the issue of Samsung laptops bricking when attempted booting from live USB. I have Samsung Series 7 NP700Z5C (-S02UB to be specific) laptop. It came with Windows 8 preloaded. Some posts claim that they disabled secure boot and installed Ubuntu in EFI mode.  On the otherhand comments on this  report state the issue to be with UEFI implementation and not with Secure Boot.  I really want to dual Ubuntu with Windows 8. Can someone help with UEFI mode installation process ?

I have a HP with Windows 7 installed. I want to do a clean installation of Windows 8 from a bootable DVD.   I purchased my Windows 8 32-bit core from the Microsoft store and I received my product key. I then burned the .ISO file to a blank DVD using imgburn. When I restart and change my BIOS to boot from internal CD/DVD and then boot from my internal DVD, I start the installation process.  After I pass the screen where I select the language and location, and click Install it stays there for a minute and then it says:     The product key entered does not match any of the Windows image   I did my research and learned that I need to add a PID.txt file to my source file containing the Windows 8 .ISO but the thing is: I do not know how to add files to the .ISO. The guide I researched is for a bootable USB and I am using a DVD.

I just got my new working notebook with Windows 8 pre-installed. After installing Ubuntu 12.10 the grub menu says that there is an "invalid EFI file path" and it won't boot Windows. Ubuntu works fine...  Is there anything I can do about this?

I was running Ubuntu 17.10 on my mac (mid-2010) as a dual-boot with Refind as the boot manager. It was functional albeit non-optimal drivers for wifi and video card.  A day ago, the Software Updater app gave me the option to upgrade and I took it. It completed the install and clean up fully but I was unable to do a final restart due to power issues. Anyway, after the power issues were sorted out, I booted my laptop, only to find that it wouldn't boot into the OS and would get stuck in a loop at a screen which was filled with lines of code that made no sense to me.  So, I rebooted with option key and booted into recovery mode and ran check disk and fix broken packages and then resumed boot. Then it booted into the OS fine. I rebooted again, and then it went back to the screen with lots of lines of code which no sense. I tried the same thing again with the recovery mode again. And this time when it booted I picked the proprietary Nvidia drivers. Now when I boot, there is just a blank screen and I cant boot into recovery mode either because there is an error in EFI screen option.  So I boot into OS X and download the ISO file for 18.04 and make a bootable USB stick and boot into that from the EFI screen. Now, it boots and once past the orangeish blue bionic beaver wallpapers, it gets stuck in a loop at a message called setting locale.  So, at this point, I can neither boot into my HDD Ubuntu install nor into the Live Disk.  My next plan of action is to try and get an ISO of a previous version and try booting form that. I'd like to avoid that if possible and stick to 18.04.  EDIT 1: I flashed Ubuntu 17.10 onto the USB storage, and that boots fine. I'll try 18.04 once again. Also, I'm using Unetbootin for flashing the USB storage.  EDIT 2: This keeps cycling over and over when I live booted from a freshly downloaded copy of Ubuntu 18.04 ISO file flashed in to a USB:    Keep in mind that when I do this on the same USB with the ISO file for 17.10.1, live boots perfectly fine.   EDIT 3: I've given up. I'm doing a clean install of 17.10.

I have a similar laptop to    But I am opening another question as the problem I face is different. The  and did not find any experience with the Ubuntu installation.  After switching from RAID to AHCI, disabling a secure boot, updating the BIOS, and play around with the BIOS option, I am trying to install Ubuntu 18.04.03.  I am not actually installing it but just using "Try Ubuntu". I pass to the bootloader the options nomodeset intel_idle.max_state=1 without which the installation stops very early. I've also played around with ipv6.disable.  Everything stops while turning on services(see attached figure). In particular acpid.service is the last thing I see, then the system freezes.  I suspect it is related to ACPI setup but don't have any clue on how to fix it. Any suggestion is much appreciated.

We downloaded Ubuntu here  just as prompted. The 64 bit.    We followed howtoubuntu perfectly, using Rufus to put Ubuntu on a new usb stick.   We installed Ubuntu. Everything looked perfect, step by step.   The computer prompted us to restart, so we did.   With the usb stick in, we are prompted to install Ubuntu. Or one time, it started and looked like we were good to go but nothing would open. But when we try to reinstall, we are told the computer already has ubuntu, would we like to install alongside?   Without the usb stick, we are told to install an operating system. "Boot device not found"  You can probably tell by my vernacular that I am not familiar with this process. How can I fix this? Just want to run Ubuntu on the laptop.   Thanks, Tabitha   Edit: this is an hp pavilion laptop, which I could probably tell you more about if I hadn't just deleted everything on it in a failed attempt to use Ubuntu.

I'm stuck on this screen. I've edited the Ubuntu boot partition while running Windows now Ubuntu does not boot anymore. In depth I have seen a lot of question like this one on here, but what I have not gotten is the replies from the people who have asked about whether the answer has worked or not. Basically tried to boot Ubuntu and it went well. It worked and I installed it something somewhere went wrong and now when I try to boot it. I looked at the other answers that said troubleshoot. So I did it ctrl-alt-1-7 but 1-6 just tells me to log in and runs a whole script than stops unexpectedly and 7 is where it says /dev/mmcblk0p2: clean Booting Ubuntu worked earlier (yesterday) but I trashed a file and then  renamed the file trash 1000 but kept the files so I renamed it ubuntu. Then I tried to restart it up on my Chromebook. It still has old entries from it but I don't know how to delete those to start ALL over. This on Ubuntu 20.04.

I sent this to boot.repair@gmail.com, still no response thought I could get a faster solution here.  I am running Windows 7 64-bit and Ubuntu 12.04 LTS on separate partitions.  The message is sent is:  Boot-Repair URL:    Originally I was unable to access Ubuntu after a windows update (Ubuntu was installed using wubi). Rather than logging into Ubuntu from the Windows 7 Bootloader, it lead to the grub> command prompt.  No matter what I did here, it would not log me into linux.  As a result I uninstalled Ubuntu from the Add/Remove Programs application in Windows 7.  I then re-installed Ubuntu 12.04 LTS using a liveCD-USB.  This time however, I created a partition.  I then restarted and got the GRUB bootloader which loads Ubuntu 12.04 LTS with no problems, however when I select windows (listed as "Windows 7 (loader)"), it just refreshes the grub bootloader instead of loading Windows 7.  I then used the Windows 7 repair disk to run bootrec/fixmbr and bootrec/fixboot.  This led to no bootloader coming up when I started my computer.  Instead I got a blank black screen with a flashing white cursor.  I went on to do a bootrec/buildbcd and bootrec/scanos.  These did nothing to change the situation.  When I ran bootrec/scanos it said that no Windows 7 installations were present.  After this I decided to reinstall WIndows 7 only for this to do nothing to change the situation.  Afterwards I did a boot-repair in which I began to get the GRUB bootloader, which would load ubuntu 12.04 LTS, but still would not load Windows 7.  I also did a sudo update-grub which recognized Windows 7 as being installed, but still didn't fix the issue of loading Windows 7.  While running Ubuntu I have no problem accessing my WIndows 7 partition which is formatted as NTFS.  It shows all the files and folders reflecting that the re-install did take place, and it also shows all of my old applications and folders in the Windows.old folder.  I am completely stuck at this point and have no clue what I should do next.  Any help you can offer me will be greatly appreciate.  Thank You  --gap

Not a COM32R image boot   is a message that the console infinitely keeps spitting out when I try to install Ubuntu 10.04 from a USB. I created the USB using the StartupDiskCreator in 11.04.  What is the reason for this behavior? What do I do to set it right?   I have followed the steps perfectly, as enlisted in the .
