I want to put windows and Ubuntu together in one pc (seems possible xD).  I reduce my hard drive to 150GB and install Ubuntu 14.04 on that. All easily. He installed all well and I restart it. Then immediately suggests a update, which I installed also. Another reboot and then it happens. The boot manager grub works and it also starts, but will not display, but it shows an black screen or there is the following error message:  [4.498559] sd 0: 0: 0: 0: [sdg] No caching mode page found [4.498600] sd 0: 0: 0: 0: [sdg] Assuming drive cache: write through [12.205496] init: Error while reading from descriptor: Broken pipe   I installed then Ubuntu ,  and  with the same problem: Either black screen or remains stuck at the points of loading. I have checked my hard disk to the cluster error and also defragmented. It is not on the hard disk and the CD-ROM drive that burns the CD it is also not, because I have also used other CD burner with the same problem.  How can I solve it?

I did a fresh complete install of Ubuntu 18.04 on my ASUS M32CD desktop.   Everything during install went fine. At the end it said it was complete complete, and would reboot. Popped the disc out. Rebooted itself back into bios so I changed it back from CD boot as primary to HD.  When it booted up for Ubuntu screen and then everything went black and can’t do anything now! Ugh. Help

I have a dumb problem that I'm hoping that someone can point me in the right direction on. I'm trying to install ubuntu 16.04.1 on a windows10 machine. I've followed all the steps correctly (I think) all the way up to the point where I am supposed to go through the install program on the thumb drive. The first problem is that it does not show the option screen that has the partition the hard drive options (see here: ). The next page (here:) only shows that my "device for boot loader installation" is the thumb drive itself.  I'm confused. I've made sure that there is in windows a free partition with no drive assigned and every other step up till the point where I reach this dead end I've followed correctly seemingly. Can anyone tell me what's going wrong?

I'm new in this forum.  I know, that this is an old problem and I have been reading other questions regarding this. However, I've been unable to find the solution.   I've been trying to install Ubuntu 14.04 on my Asus Vivobook F200MA machine from USB, but the screen goes black, if I choose any of the options. It is a new machine, with only freedos on it.   If I follow the instructions on     it still doesn't work.   SATA is set to AHCI, Secure Boot is disabled, CSM is enabled.   Do you have any ideas, how I could install it?   Edit:   I have tried:   checking the usb for errors (no errors), verified the integrity (alright),  disabled the secure boot enabled csm set SATA to AHCI from the menu (try without installing, install and check for defects) because the screen goes black.

I'm sure this has been answered somewhere on here before (I even found kinda a guide , but seemed to be a bit spotty and incomplete) but I was wondering if someone could assist me or at least point me in the right direction to get what I'm trying done accomplished.  Basically I installed Ubuntu 14.04 (via "Guided - use the entire disk and setup LVM") on a 20GB disk. I then physically added a clean 80GB disk to the machine, which it detects as 'sdb'.  Basically my question is, I want to be able to add/combine the allocated amount of space from the new disk (80GB) to my machine so that instead of showing two drives (20GB and 80GB), it simply shows one drive (100GB). I'm not worried about RAID or any other special add-ons.  I'm somewhat new to Linux, but understand that I need to use LVM to accomplish this.  If there is anyone who can help me out or link me to a helpful guide/tutorial, it would be very much appreciated! Not sure if this is needed either, but here is my 'fdisk -l' and '/etc/fstab' output:  fdisk output (shortened):  Disk /dev/sda: 21.5 GB, 21474836480 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sda1    *       2048      499711      248832   83  Linux /dev/sda2          501758    41940991    20719617    5  Extended /dev/sda5          501760    41940991    20719616   8e  Linux LVM  Disk /dev/sdb: 85.9 GB, 85899345920 bytes Disk /dev/sdb doesn't contain a valid partition table  Disk /dev/mapper/ubuntu--vg-root: 20.4 GB, 20392706048 bytes Disk /dev/mapper/ubuntu--vg-root doesn't contain a valid partition table  Disk /dev/mapper/ubuntu--vg-swap_1: 801 MB, 801112064 bytes Disk /dev/mapper/ubuntu--vg-swap_1 doesn't contain a valid partition table   /etc/fstab (shortened):  # &lt;file system&gt; &lt;mount point&gt;   &lt;type&gt;  &lt;options&gt;       &lt;dump&gt;  &lt;pass&gt; /dev/mapper/ubuntu--vg-root /               ext4    errors=remount-ro 0       1 # /boot was on /dev/sda1 during installation UUID=26710773-7a64-4f34-a34e-0057cb1739d7 /boot           ext2    defaults        0       2 /dev/mapper/ubuntu--vg-swap_1 none            swap    sw              0       0

Actually, I have done something terribly wrong. I did not want Ubuntu 13.04 on my PC anymore. I was sick of dual-booting every time the PC starts, and I wanted to return to Windows as well. (My version is Windows XP MCE SP2). The mistake I did is that I simply used EASUS Partition Manager to delete the Ubuntu partitions. But what went wrong here is that, even when I did it, the GRUB keeps trying to load. It says that GRUB could not be found and finally ends up running GRUB Rescue.  I cannot "Repair" my PC using the Recovery Discs (containing Windows XP MCE), it only gives me an option to press "F", which will format the HDD to re-install the OS.  Although, the best part is that I can still log in to Windows. Because, when I boot from the CD's, it does not give me a "Repair" option, but only "Format" and "Quit". By using "Quit", it takes me straight to Windows.  But I do not want to keep doing this same thing every time I start my PC. Neither do I want to Format my Hard Disk. I have tried a few applications, like EasyBCD which do nothing. So I want a good solution for it.  Is their any way to install MBR through Windows or maybe Ubuntu terminal? Even if i can't access Ubuntu again? And what after installing Ubuntu again. Any safe method to uninstall it?

My friend has been using ubuntu 10.10 on vmware player for many days now. But today, it has a problem booting, so we started the ubuntu live cd to try and fix it.  Running sudo fsck /dev/sda1 (got from ) says that the device or resouce busy. So, I'm guessing the partition was not unmounted correctly on the last shutdown for some reason.  Any help on how to fix the problem would be appreciated. If you need any further information, please provide the command to get it, as we have little knowledge of that.  Thanks.

Okay, I apologize if there are similar threads... but I've scoured the internet and never have I run across a helpful answer. So I'll ask here...   I have an old laptop, an Acer Aspire 5515... It was running Vista and was taking 5-10 seconds to just do anything, even as simple as opening a folder. So I decided to install a windows-user-friendly version of Linux - something I've wanted to try for a long time. I ended up settling on Kubuntu because I read somewhere that it's medium-light weight, and good for people used to running windows, after all, I can always replace it with something different later on.   I went to the ubuntu site itself and downloaded  "kubuntu-16.04.1-desktop-am64"  Then the problems started flowing in. Some of it user error I admit... first the CD I got wasn't big enough, then I forgot you can't copy past an iso file, then I couldn't get the Acer to boot from cd drive  Eventually, I fixed these... I burnt the iso image right, used a larger DVD, and changed the bios to boot from the cd. I went to try to just 'try' Kubuntu but that just wasn't working very well, so I just went and tried to go ahead and replace the OS. I knew it would kill everything on the Vista, but I already transferred the files I wanted to keep and the computer was unusable as it was, so I figured why not.   I went through with trying to do the installation, and the first time got to about 80% when I got the Errno 5 Input/Output Error  Alright then... it said something about heat so I placed the computer on a low running box fan as a make shift computer fan (It was getting hot anyway), and I tried again. Made it to about the mid-60s and got the same error.   This time, I went and I double checked the iso... it's indeed the most recent one on the Ubuntu site, and then I used winMd5sum, which says the checksum is correct. I then got another disk and downloaded imgBurn and burnt a new disk at the lowest possible speed (tried for 1x, but it did 2x).   Tried again and it still pulled the same error around the same spot.  So this time at the bootup screen I pressed shift and chose Check for Defects, it returned with Errors found in 1 file  The memtest86 says no errors.  So I'm assuming that means there's a problem with the CD/iso? The check sum was supposedly correct and it was burnt on the lowest possible burn with trusted software. Also, the cd drive works just fine and the disk itself is brand new without a scuff on it.  I'm pretty stumped what to do. I'm going to try to find a cheap flash drive at the dollar store or something to try to boot from USB, but if there is any troubleshooting I could do to get this to work without having to spend money I can't really afford, that'd be really helpful.   As it stands I have a nearly 10-year-old computer with no OS whatsoever on it because the windows section is all deleted, but the Ubuntu section is not fully installed.

I've posted a question  that I have a 32bits windows 7 on a dual boot machine with ubuntu 10.04 upgraded to 11.04. From the responses I had from the questions, I decided to reinstall the windows 7 but this time a 64bits version.  I've install the grub on the first section of the HDD on which ubuntu is install, meaning the 2nd Drive.  I still want guidance before I proceed.  What would you suggest me as best way to achieve that without disturbing the boot loading.  thank you for reading this.

I bought my PC with Windows 10 on it, later installing Ubuntu for dual-booting. Recently, I wanted to replace the HDD inside with an SSD of the same size, so I copied all the partitions to the SSD (GPT partitioning) using GParted and installed the SSD in the laptop. On startup, GRUB is loaded and I can:  Boot Ubuntu normally Select the &quot;Windows Boot Manager on /boot/sda1 or select bootmgfw.efi manually, however it loads a Recovery BSOD, stating the following with options to access the recovery environment (F1) or boot parameters (F8) but those don't work (same screen): File: \WINDOWS\system32\winload.efi is missing or broken Error code: 0xc000000e    As I understand it, Windows Boot Manager is loaded but cannot find the Windows boot loader (probably because not looking into the right partition), so what I need to do is give the right partition to the boot loader, but I have no idea how to do that. How do I fix this, preferably something that can be done from Linux and doesn't involve a reinstall of Windows?

I have a problem I have had before. When I create a USB drive to install Ubuntu 12.04 using startup disk creator, it won't work. It doesn't give me any errors, but when I restart the PC to boot into the USB drive (settings are correct in BIOS), I get the option to: 1) Try Live CD 2) Install Ubuntu 12.04 3) Check the disk  I choose option 2 and after that, nothing happens, just black screen no matter how long I wait.  I tried creating the USB using unetbootin, on both Ubuntu 11.10 and Windows 7, but same issue.  I have had this problem installing Ubuntu 11.10 too, but it was solved by creating the USB drive in Linux Mint. But I don't have Mint installed now, so I hope someone knows what the problem could be. Thanks in advance!

I'm having a problem installing Ubuntu 12.04 on my ASUS UX31A alongside Windows 7; I tried to launch os-prober in my terminal and the only option I get is:   /dev/sda5:Windows Recovery Environment (loader):Windows1:chain   while Windows 7 (mounted on dev/sda3) is not shown.  This is what I see in my Disk Manager in Windows 7:    C: basically is the partition with Windows system's file, while the D: one is for data), while this is what I see when I launch GParted:     May it be because Windows is installed on SSD? How do I know that? Is it safe if I proceed with the installation for computers with UEFI, SSD and HDD? I'm not sure that's my case.

I want to install the latest ubuntu (12.04.2 LTS) in my ultrabook asus S56C.  I tried to boot with USB &amp; CD, but both stuck in black screen after choosing "Try Ubuntu..." or "Install Ubuntu"...  Need some help.  Thanks

I'm new to how Ubuntu works and installed it yesterday alongside Windows 7, but in doing so I have created a few problems. I have partitions for Windows, Ubuntu, System Recovery, and storage for all my files with the intention to access them on either OS, but I don't even see all of my drives listed on Home Folder. Not to mention that  during the Ubuntu instillation I managed to screw up any chance of booting to the Windows side of things at all. I'll fix Windows once I get my hands on a copy in a couple days, but in the mean time any suggestions for accessing my files?  If you need me to find any data about my computer to help you figure out what's wrong with it, please don't hesitate to tell me what I need to show you. Thanks

After running a VM and logging out, I got a black screen. I powered off and re-started but got the same after the bios option in start up passed. Several attempts went bye with the same result. So I fiddled with bios boot options a bit and was able to get to a different looking Ubuntu start up screen which, after entering pass key would run a series of commands that were too numerous and frantic to make out. They appeared to be overlapped/layered (the text that is) and seemingly repeating endlessly. I had to power down to get it to stop and re-booting just had the same effect. Finally, I hit the down arrow key when prompted for "disk sda5_crypt" at the pseudo Ubuntu log-in screen I mentioned before. This brought me to an all black screen which read something like:  lvmetad not active cannot process volume group "umbuntu-vg" unlock disk sda5_crypt**   From here I entered a password and Ubuntu start up ran.  That was an unsettling hour or so and I'd like to avoid that in the future. Any ideas what caused it and how to avoid it going forward?  Should have said this before but Ubuntu is the only OS on my machine and my optical drive cannot be opened manually.
