I've got Linux Mint 17.1 on my laptop installed by someone else and I want to replace Mint with Ubuntu. I don't have a Windows system on it - just Mint.  Can anyone tell me - in newbie friendly terms - how to do that?  When I type df -h in terminal, the result is as below:  Filesystem Size Used Avail Use% Mounted on /dev/sda1  684G 189G 460G 30% /  none       4.0K 0    4.0K 0% /sys/fs/cgroup udev       1.9G 4.0K 1.9G 1% /dev tmpfs      386M 1.4M 385M 1% /run none       5.0M 0    5.0M 0% /run/lock none       1.9G 32M  1.9G 2% /run/shm none       100M 28K  100M 1% /run/user

How will Ubuntu automatically allocate the disk partition sizes when we select Erase disk and install Ubuntu during installation?    Can the settings for automatic space allocation be changed?

I've been using Ubuntu for 2 years and now I want to make my own. I just decided to get the Ubuntu minimal iso for the core of my custom Distro ... but everything seems so confusing!!! could anyone give me some help about how to start and add some packages and X, a good documentation could help as well.

I have a / partition which contains /var and is too small. I have another existing partition with enough space.  Here is my df:  File system          Size. Occ. Avai. %Ful.

I have Ubuntu 14.04 with a lot of packages and work related stuff that I am very happy with it. It is installed on my main SSD drive which is a 120GB one (I had choosen "/" when I installed ubuntu, so I beleive everything should be on this drive). It shows up as /dev/sda  Now I have added another SSD to my computer which is a 240Gb. I do not have any other storage media at hand at the moment (e.g. external hard drive).   Since the new 240GB drive has obviously more capacity and is faster (a newer generation than my 120GB one), I want to move my Linux to this new drive. This new drive shows up as /dev/sdb and at the moment it is not formatted or anything (I have literally unpackaged and inserted in my PC right now :P)  How can I safely move my linux installation to the new drive?  I can change the SATA cable so the new drive shows as /dev/sda if necessary.  This is the output of "fdisk -l" if that helps:  Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00076d7a     Device Boot      Start         End      Blocks   Id  System /dev/sda1   *        2048   226064383   113031168   83  Linux /dev/sda2       226066430   234440703     4187137    5  Extended Partition 2 does not start on physical sector boundary. /dev/sda5       226066432   234440703     4187136   82  Linux swap / Solaris  Disk /dev/sdb: 240.1 GB, 240057409536 bytes 255 heads, 63 sectors/track, 29185 cylinders, total 468862128 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000  Disk /dev/sdb doesn't contain a valid partition table

I have backups up everything, but I'm still uneasy about the process and would like confirmation. I'd rather do this one time correctly. I want to shrink /dev/sda6/ by 200GB and reallocate it to /dev/sda2. I boot a LiveCD and turn off LinuxSwap (locked otherwise). I've been reading that it is very hard to move &quot;left&quot; when partitioning and other AskUbuntu threads are confusing me. Do I need to resize /dev/sda6 by 200GB &quot;preceding&quot; (rather than &quot;following&quot;), and then resize /dev/sda4 by 200GB? A little guidance would ease my nerves of messing everything up. Thank you ahead of time.

I have installed Ubuntu 12.10 on my laptop, but would like to install windows for the purpose of gaming (Hallelujah). But I haven't left any unpartitioned parts of the HDD so now I am stuck on (How to remove one partition from ubuntu and use it to install win7 in a safe way?) I do not want to reinstall everything all over again, but definitely want to play games on my laptop.  I do not want alternatives with Wine or PlayOnLinux, cuz I have runned a few games and they were all buggy, I want dual-boot.  fdisk -l output:  **Disk /dev/sda: 750.2 GB, 750156374016 bytes 255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xe2cf4679     Device Boot      Start         End      Blocks   Id  System /dev/sda1   *        2048     2000895      999424   83  Linux /dev/sda2         2002942  1465147391   731572225    5  Extended Partition 2 does not start on physical sector boundary. /dev/sda5         2002944     4001791      999424   82  Linux swap / Solaris /dev/sda6         4003840     6002687      999424   82  Linux swap / Solaris /dev/sda7         6004736   406003711   199999488   83  Linux /dev/sda8       406005760   606003199    99998720   83  Linux /dev/sda9       606005248   706002943    49998848   83  Linux /dev/sda10      706004992   879212543    86603776   83  Linux /dev/sda11      879214592  1035462655    78124032   83  Linux /dev/sda12     1035464704  1075462143    19998720   83  Linux /dev/sda13     1075464192  1115461631    19998720   83  Linux /dev/sda14     1115463680  1269835775    77186048   83  Linux /dev/sda15     1269837824  1465147391    97654784   83  Linux**

These are my current disk partitions. /yedek is for some personal backup files. As you can see there is only Ubuntu on my PC. I will install Windows, too. Because of this I want to shrink /dev/sda3 . It currently 546GB and I want to split it: 300GB for / and 246GB for Windows (NTFS) is OK for me.  I'm using GParted for the first time. How can I shrink /?  I don't want to lose any datas from Ubuntu.

As the output of df -h shows here, something is eating up 5GB of free space. So, it's not available to use.   I'm also noticing sometimes that the hard disk gets filled up to 100% sometimes. So, I had to restart the machine or delete some unncessary files. Only noticed these in /home partition. Don't know whether these two are related, but appreciate if anyone can put some insight into this.  $ df -h Filesystem            Size  Used Avail Use% Mounted on /dev/sda8             100G   92G  2.7G  98% /home

I was using df -h to print out human readable disk usage. I would like to figure out what is taking up so much space. For instance, is there a way to pipe this command so that it prints out files that are larger than 1GB in size? Other ideas?  Thanks

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

I have installed Linux Mint and now I want to change it to Ubuntu but I have a lot of apps and information on it.  Is there any way to get Ubuntu without losing data? Or how to back up my information and apps, then install a fresh Ubuntu and copy the backup on it?

I recently upgraded from Mint 12 to Ubuntu 12.10 + Cinnamon.  I have an external usb drive that when I plug it in, automatically mounts to /media/[username]/Backup/.  Thing is, under Mint, it didn't include the [username] portion.  It just mounted to /media/Backup.  My question is, how do I switch back to that format?  I don't need the drive mounted under my username.  Just under media.  Thanks in advance.

I would like to be able to adjust the partitions shown below. Specifically, I want to add an additional 10GB from the unallocated space to /dev/sda5 (Ubuntu install). I will then format the remaining unallocated space as NTFS so it can be shared data between Windows and Ubuntu.   I am unable to increase the size of /dev/sda5 - I am only able to shrink it.  Any assistance would be greately appreciated.

I cannot access ubuntu system on my pc, the error message: "the system is running in low graphics mode" and I tried some commands I searched from internet.   I found out a problems seems there is no available disk space. I used "df" and "du" commands to check, the results are as follow:  du -j --max-depth=1 23G  ./home 3.3G ./usr  ......  28G   and  df -Th  filesystem   Type   size    used   available   use%    mounted on  /dev/sda5    ext4   68G     68G    0           100%    /   how would I clean up the system for more disk space?

I am new to linux/ ubuntu and just downloaded the v11 of ubuntu to learn linux. I faced this "No root file system is defined" error while trying to install it. This is how I was proceeding -    Downloaded ubuntu v11 from the ubuntu.com website, wrote the iso into a bootable cd, and then got into the linux installation process on restarting; everything fine till here. In one of the screen during installation, there are three choices - install alongside windows, something else etc.. Since I have windows 7 in the C drive, I selected the first option - "Install alongside another OS".      Let me interrupt here to give my existing system details - HardDisk   size: 640GB.  Number of existing partitions - 5 C drive - label   windows - 160GB - has windows 7 installed D drive - label linux -   160GB - does not have any data E drive - label backup - 100GB - has   some data F drive - label entertainment - 100GB  - has some data G   drive - label work - 90GB  - has some data All of the above are in   NTFS format.    In the screen that follows, an image is shown with 2 parts and each part is shown to have size equal to 80GB. There is a horizontal slider in the middle of these two images, with which I can resize the partitions. The right side partition is labeled Linux. There is also an option to do 'advanced partitions'. On clicking advanced partitions on the above screen, a new screen is shown in which the partitions existing in my computer are shown - but the labels are different. I see that there are two partitions with size = 160GB each (as expected), and so I assumed that the first 160GB would be my existing C drive and the second on would be the partition which I had labeled as linux (drive D). So I selected the linux partition and clicked on proceed/ install now, and then this error was shown - "No root file system defined".. and I cannot proceed after this.   Please let me know two things here:   During the screen in point number 3 above, the image with slider was shown. Which partition (drive c: or d: or anyother) is being referred to here? Which one am I actually resizing - is it the existing c: drive which has windows 7 installed already, that is getting shrunk and then ubuntu getting installed in the remaining space? What does ""No root file system defined" error mean? How do I select the proper partition and continue with the installation?    P.S.:  I had already partitioned my drives as mentioned above, and the D drive with 160GB was specifically left free for installing ubuntu. I would like to Select D drive during setup and install ubuntu here, while still keeping the already installed windows7 in C drive.  Thanks!
