I want to install Ubuntu 14.04 on a USB Hard Drive from my USB stick. So I went through a few similar questions on the website. However, I have a few special requirements.   I don't want any changes to be done to my C or D drive. I want to set aside 50-100 GB on my External HDD completely dedicated to Ubuntu and all of its needs, including storage. The rest 900-950 GB (on a 1TB drive) need to be used for different purposes, along with Windows. So the two "sections" should not interfere with each other in any way.   So in short, I don't want to change my C and D drive. I want Ubuntu to stay confined to the dedicated 50-100 GB on the External USB HDD, and not mess with the rest of the space.  Also, I know nothing, absolutely nothing about Ubuntu. It is an OS I want to try out. So step by step instructions would really be appreciated.   Is this even possible? Can my computer boot from a USB device with an OS as well as other stuff not related at all to the OS? I'm really confused.  Oh and BTW I don't want Windows to be harmed in any way. It should be such that I can boot either from Windows or from Ubuntu depending on my choice.

I have an external Hard disk with 500 GB capacity.  I have data filling almost 300 GB.  I want to install Ubuntu into it.  I have downloaded the iso and have written it to a USB drive as a bootable device.  My laptop runs on Windows 7.  What is the way to install Ubuntu in my external HDD.  I have yet to do any partitioning.  I would not like to lose the data.

I'm in the middle of installing 13.10 and the Ubuntu page I was following on how to install from a USB stick says nothing about these two choices (on the Installation type screen):     1) Encrypt the new Ubuntu installation for security (you will choose a security key in the next step).      2) Use LVM with the new Ubuntu installation (this will set up Logical Volume Management. It allows taking snapshots and easier partition resizing)   I'm a writer using the computer for mostly writing ebooks but I also do all the things most people do: buy stuff online, online banking etc. I want my information to be safe but I don't want to overburden my system with security stuff either. And I've read a lot of the similarly themed questions here on the forum but they've all been about stuff more technical than I'm concerned about.   Can somebody please just tell me in real layman's terms about the implications of these two choices? Thank you.

Every issue of Ubuntu LTS since 8.04, I have made a Full install of Ubuntu to USB flash drive, and recorded each step..  This has been intended to make a guide/check list for users wishing to create Full install bootable flash drives.  Previously the procedure worked for BIOS boot if created in BIOS and for UEFI boot if created in UEFI.  This year for 20.04 the instructions should work for both creating and running the drive booted from either BIOS or UEFI.  The question is:  How to Create a Full Install of Ubuntu to USB device with Step by Step instructions that work in either BIOS or UEFI.

I am brand new to Ubuntu. I have just build my new PC, it has 2 separate hard drives installed in it. I would like to install Windows 10 on the first SsD (They are both 250GB Samsung 850 EVO) and i would like to install Ubuntu on the other and be able to choose to use either one or the other on dual boot. As i said I am brand new to Ubuntu. In fact, I have not downloaded or installed it as yet. I would like to know if this dual booting from separate hard drives is possible.

I'd like to fully install Ubuntu 12.10 onto a 16GB USB 3.0 flash drive, not create a LiveUSB, but to treat the flash drive as an external hard drive.   I've read it's possible and I know my computer can boot from it. However, it doesn't work when I try. I've booted a LiveUSB from another flash drive and installed Ubuntu onto the 16GB one. It finished successfully, but when I try to boot from it and it takes me straight to Windows 8 instead. I feel I've done something when installing the boot loader.  It'd be great if I had some step-by-step instructions for:     how many partitions to make,  what kind,  how big, and  where to install the boot loader.

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 new to Linux and wondered where I can get useful info so started here. 1st off can I use the same PICTURES, VIDEOS, MUSIC &amp; DOCS already on hard drive. I remember a window appearing during Linux installation saying it would require about 300gb for this, I clicked on OK but don't know how to get to them to appear.  Since this my hard drive has gone down by 300 odd gb?

I have two hard drives. One is used for Windows and one is empty. I want to install Ubuntu on the empty hard drive. The Windows hard drive is disk0 in Windows and the empty hard drive is disk1. When I install Ubuntu and it asks where I want to install it, I choose "Something Else" but I am stuck there. What do I choose for "boot loader installation"?

I was using:  dd  if=/path/to/my/ubuntuiso/ubuntu.iso  of=/dev/sdb1  bs=4M  &amp;&amp;  sync   In order to create bootable Ubuntu USB drives on older Ubuntu versions. It was working perfectly. Sometimes I used the Startup Disk Creator program, which  worked well.  But when I use the same methods on Ubuntu 16.04 LTS, I get some warnings while formatting it afterwards.   The installation media works as expected, but when I try to format that USB stick after my work is done, I get the following warning :    The partitioning of that Pendrive looks strange :    And it also shows my 16GB pendrive as 64GB.  After struggling a lot with Gparted, I will somehow format it. But Why is it happening like this ?? Is there any better methods of creating bootable Ubuntu in 16.04 ?  EDIT : there is a related question . But my question is not about how to format it properly. My question is "How to create a bootable USB without that errors." &amp; "Wht are the causes of that error"

Basically what I want to do is install a fresh copy of Ubuntu from Ubuntu. It is an older machine so usb boot doesn't work and I don't see why I need to waste a CD to do it. Currently running Ubuntu 11.10.  I have a 1TB drive and a second 500GB drive for backup. The 1TB drive is partitioned as:  20GB   sda1 Windows XP 20GB   sda3 Free for new OS  ~800GB sda4 Data (ext3) 60GB   sda7 /home (ext4) 20GB   sda6 / (ubuntu 11.10 ext4) 2GB    sda5 swap   After researching I decided that using unetbootin was the best option. I chose Hard Disk (frugal install) and the only option for which disk is "/". That worked and I quickly rebooted into Ubuntu 12.04 live.   Chose to install and picked custom options, set sda3 for / and sda7 for /home. The installer started but hit a wall at detecting other operating systems. It was trying to mount sda6 to find out about the existing os's on the machine, for the purpose of installing grub. And it couldn't umount sda6 because that was currently mounted as cd drive for live cd. I couldn't find an option to make the installer skip this step (I could later fix the grub in 11.10).  I have another drive with 4GB free partition and if I could get unetbootin to install to there it would all work.  So my question is - how do I get unetbootin to install to a different disk for hard-disk install? (I don't think USB Drive mode will work because it will install the grub to that disk -  but I might be wrong!)  or  How to fresh install Ubuntu from Ubuntu?

I'm not even sure if i worded my question right but, I'm familiarizing myself with Ubuntu and want to install it on a new desktop I just finished putting together so I'm trying it on my laptop via live usb first.    I had trouble mounting my NTFS windows partitioned disks, solved that problem but I also see a disk that has the exact amount of memory I alloted for persistence. I try to access it but it shows the same ACL error I got when my NTFS disks weren't mounting.    I've already downloaded some stuff and made some things with LibreOffice and want to know if those things have been save automatically or if I have to mount the usb disk for it to be persistent.

A friend just complained to me about Ubuntu being slow.   Although I've noticed a certain lack of snappiness with Linux vs Windows in the past, I really can't say I've had much to grumble about with the recent distributions of Ubuntu. That said, his objections seem much worse than the ones I used to have and I know that his current setup is significantly more powerful than my laptop.   And then it turned out he is running Ubuntu off an external HDD hooked up via USB2.0. The HD enclosure is USB3.0 but apparently he can't manage to get it to boot on USB3.0 so he switched to one of the USB2.0 ports or whatever and that works, albeit not very well.  Now I would expect USB to add some overhead to communication between the computer and the HDD; SATA is after all designed to get the maximum out of a hard drive, whereas USB is, well, universal.   What are your expreriences with booting off external HDDs?  Edit: Does anybody know just how much of a slowdown can be expected?

I want to format my USB stick to ext4 and just use as I would any other typical non-linux format drive (FAT32, exFAT, NTFS).   That is to say, I want to be able to plug the usb stick into any of my linux machines, and read/write to it without needing to adjust permissions, like doing chmod or chown stuff.  I would prefer to use GUI partition software like GParted, rather than command-line commands, though I welcome any solution!  I'm sure a post like this is duplicate flag heaven for some, but after browsing 6~10 SO and forum posts from google, I didn't find a simple solution to my question. Seemed like everything was about adjusting permissions on a per-user basis. Maybe you just cannot use ext4 drives with the same brainless convenience as NTFS.

I have installed Ubuntu several times on my thumb drive. First times were on 8 GB thumb drives. I noticed I could not save anything as when I rebooted, it was all gone.  So, I got a 30 GB drive, tried installing again... and same thing.  Now I've found out I am running a LIVE version... not actually an installation.  So, for the somewhat novice who cannot do command-line installs,  step by step is there a way to install ubuntu-12.04.3-desktop-i386.iso using, unetbootin-windows-585.exe to a 30 GB USB stick using my Windows 7 machine?

Okay, so here's the story.  I am trying to install Ubuntu 13.04.  I currently have a 2TB drive in my computer where Windows 7 boots from, and a secondary 500GB drive that also has a bootable installation of Windows 7, because the version on the 2TB is a clone of what was on the 500.. I do not need any information on the 500 as I already have it moved over to the 2TB.  What I want is to completely reformat the 500 so that it has about 300GB for NTFS and the rest for Ubuntu.  However, I can't seem to find a straightfoward way to do that in the Ubuntu installer.  If I click on "Install Ubuntu alongside them," it does not give me the option to select my 500GB drive, only my 2TB.  I do NOT want any linux partitions on my 2TB drive.  I do not want to click, "Erase disc and install Ubuntu" for obvious reasons.  Finally, clicking "something else" brings up a menu that is quite confusing.  I can kind of figure out how to use it, but it's not as straightfoward as I'd like..  Further, I know that Ubuntu requires a SWAP partition, but I do not know how much, or even how, to allocate that with the stupid dropdown menus it gives me.  So, to get to the point..  What is the easiest, safest way to do what I want to do?  That is, allocate approximately 200G for Ubuntu on my 500G drive, and be able to choose between Windows 7 on my 2TB drive and Ubuntu at startup - all, of coarse, without touching the 2TB drive at all.  Thanks!

So I know I can make a persistent LiveUSB whereby there would be anywhere up to 4GB (I think that's the max) of persistent storage for downloads, etc.  I am asking the opposite, in a sense. I'd like to configure a USB install to have the platform adaptability that a Live OS offers while fully utilizing the 120GB of space I have.  In essence I'm hoping to have a boot up install that reconfigures most/all the hardware/drivers as necessary every boot as I'd like to be able to boot off of it on nearly any machine. (Within reason - they will all be 64-bit)  The biggest gripe with doing multi-platform booting is the video driver stuff. Sometimes the system I'm booting off of is AMD, sometimes Nvidia, sometimes Intel.  Alternatively, a usable answer may be a way to better configure the LiveUSB setup for more storage utilization and customization.

Hardware:  I've got an SSD (c),an internal HDD (d), an external HDD (e) and a USB flash drive (f).   How this all went down:   I downloaded Ubuntu and used a program to install it on my (F) drive. I reset my computer, ran the (F) drive for boot, and installed Ubuntu. I reset my computer, and it forcibly automatically booted into Windows 10 instead of Ubuntu. I went into Windows 10, and used a program called Easy BCD, by NeoSmart. I followed their guide, but after step 6, it wasn't the same for me. Their guide said that upon rebooting, I should see a grub screen that lets me choose between Windows/Linux and a few other options, however my computer would only boot into Windows 10.  I decided to follow the rest of the guide regardless, however by the end it would let me boot 'windows' or 'linux', but the linux option would always break. It went to a screen with lots of commands, that I thought -may- be a barebones Linux or something, but it definitely wasn't Ubuntu.  I decided to reinstall Ubuntu using the USB flash drive. Upon resetting, no matter what hard drive or format I select for booting (besides the F drive), it says An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. I can boot the F drive and run Ubuntu, but it's a one time version that doesn't save any of my data. When I went into the installation, it still says that I already have Ubuntu installed on the 4TB HDD and that I have Windows 10 installed on the SSD, however I cannot seem to boot into either of them.   TLDR: Windows 10/Ubuntu are both installed, Windows on the internal SSD and Ubuntu on the external HDD. Ubuntu's installation program on the (F) drive recognizes them, however, when I try to boot anything it says An operating system wasn't found.   When I press F11 and force it to boot from the SSD it says:  error: no such device: 83b6c64d-9a2c0467b-a02c-6374ee6ac3dc.  error: unknown filesystem. Entering rescue mode. . .  grub rescue&gt; _   and it will allow me to type some commands.
