I want to install Ubuntu Desktop 17.10 on my Windows 10 computer. Problem is, I tried to use Unetbootin and when I selected it on the OS menu, it displayed an error message saying to insert a Windows 10 disk (even though I have already got Windows 10 installed) and showed me the file I "was missing". So I tried to find the software called Wubi which apparently is on the download page for Ubuntu, but I couldn't find it. I don't think it's even on the ISO. Can you please help? I don't want to use a VM.

Update: I have finally gotten a USB.

    Possible duplicate of What is the proper way of creating installation media from Ubuntu iso? and How do I install Ubuntu alongside a pre-installed Windows with UEFI? and you are right, the Ubuntu 17.10 ISO file does not include wubi and UNetbootin is not so good for making bootable Ubuntu installation media. – karel Feb 22 '18 at 09:20

    Wubi is not supported on Windows 8 or 10. You can either (1) install Ubuntu as a separate OS and use Dual Boot (i.e. at start-up time, choose which OS you want to boot) or (2) use VirtualBox on Windows 10 and install Ubuntu in a virtual machine. – Jos Feb 22 '18 at 09:21
  • It is possible but rather difficult to install Ubuntu without a USB drive or DVD disk. Why do you want to install without it? Is there no USB port and no DVD drive on the computer? Can you connect two drives internally (for example two hard disk drives)? Can you use another computer with USB or DVD to do the installation? Do you mean version 7.10 (passed end of life long ago) or the current version 17.10.1? – sudodus Feb 22 '18 at 09:25

    It looks like you were able to create a bootable USB stick with Unetbootin. Did you? But when you are trying to install Ubuntu with this bootable USB stick it asks for the signature file for Windows 10 because you have still "secure boot" enabled in the systems BIOS. Try to go in the systems BIOS and verify that "secure boot" is disabled. (When "secure boot" is enabled it will check for a predefined signature on the boot medium, which is typically only available for Windows boot/install media.) – jringoot Feb 22 '18 at 12:20
  • My Windows 10 does have a virtual DVD drive I can mount to, but other than that I don't have any spare DVD-Rs to write to, nor any USB sticks. And Netboot seems to complicated to use. Are there any alternate downloads for 7.10 that includes an installer? – Anaussie Feb 23 '18 at 04:37
  • A USB pendrive is rather cheap nowadays, and it can be reused for new purposes (which is different from standard DVD disks). The size should be at least 2 GB. If you don't want to buy one, maybe you can borrow a USB pendrive from a friend, relative or colleague. (It will be overwritten, but can be restored afterwards to a standard storage device.) ; 2. Please consider a current version of Ubuntu. The version 7.10 passed end of life years ago, and is no longer supported.

  • My mistake, my version of Ubuntu uses 17.10.1, not 7.10. – Anaussie Feb 23 '18 at 10:10
  • That's good (17.10.1) :-) Anyway, iso files of Ubuntu contain an installer, but you should start by installing the iso file to a USB pendrive (or DVD disk). All other alternatives are more difficult. – sudodus Feb 23 '18 at 10:35
  • Update: I have finally gotten a USB. Thanks for the help anyway. I appreciate it. – Anaussie Mar 07 '18 at 04:40
  • Good luck using your USB stick to create a live system and using that live system to install Ubuntu :-) You are welcome to ask new questions, if there are problems ... – sudodus Mar 07 '18 at 07:02
