  • Is there any way to install Ubuntu on this computer without any external disk (CD, USB drive, etc)
  • Note : This computer is 64-bit, so this issue did not help me.
  • WUBI does not support UEFI, and This computer uses it.
  • No Virtual PC programs like VirtualBox or VMWare, because it takes memory.

EDIT : I already found a USB drive in my home, so now it is installed on my computer xD

You could install VirtualBox in windows, then Ubuntu inside of that... – Scott Goodgame May 31 '13 at 12:07

There are 4 ways to install Ubuntu as dual boot on a machine already running windows.

  1. Use a CD. You can't/won't do it.

  2. Use a USB drive. You can't/won't do it.

  3. Use the .iso file in a virtual machine as a means to avoid CD/USB such that it also boots alongside Windows. You claim you can't/won't do it.

  4. WUBI. Not compatible with UEFI.

Sorry, but you're stuck. It may be possible to do something really cunning using Windows ext2 drivers, an iso image extractor and a lot of both Linux and Window know how, but if you could do that you wouldn't need to ask questions here.

I've already provided an answer for machine that have no CD and won't boot from USB. If that's not the solution then you've not communicated your question properly.

Thanks for the question, and I'm so glad you SUCCEDED reading my question! – minmaxavg Jun 8 '13 at 3:39

Do your repartitioning from Windows, it will not let you do any damage to the Windows OS this way. Leave the partitions where you'll install Linux unformatted, I assume you'll want to use ext4 and swap on them, and reserve a small partition, maybe 1GB, for the Linux installation media, that you can format to FAT32; copy the content from your installation ISO (not the ISO file itself) to this partition; add an entry to this partition to the Windows boot loader with EasyBCD, you can find how on the Internet, such as in this article. Note the order of your partitions so you'll remember which one you'll format and install on it, then restart and boot into the Linux live session from the install partition and perform normal installation. The installer will recognize the existing EFI system partition and will copy a boot entry there, but you can add another entry for your installed Linux to the Windows BCD the same way you added for the install partition.

+1 for actually having a solution. :) – ams Jul 12 '13 at 14:34
@jinoh67 There's plenty of room for cock-up here! Overwriting a partition, or corrupting a file system could happen so easily. But, that's true for any install system, even a LiveCD. – ams Jul 12 '13 at 14:36
@ams I found a USB drive in my home, so now I already installed it! – minmaxavg Jul 15 '13 at 6:23
@ams I just marked it as accepted, but as you can see it uses EasyBCD which isn't compatible with UEFI. – minmaxavg Jul 15 '13 at 12:15

Do you have access to a screw-driver and another computer?

Windows must be installed on the same machine that it will run on, but Linux is less fussy. :)

When I've been in this position before I've removed the hard drive from the problem computer and attached it to another computer. (I used a cheap external USB drive enclosure, but you could install it directly into the other computer.)

I'd then install the new OS onto the drive using CD/USB. (Actually, I did it in a Qemu/KVM VM booted from the .iso image, but that was just showing off.)

Finally, I moved the drive back to its real home and it should Just Work. You might have trouble with UEFI though (maybe you can disable secure boot in the settings)?

I said "Install without CD or DVD", and it is NOT about UEFI problem. Please read all before reading, as I said on the top of the article. – minmaxavg Jun 2 '13 at 7:26
I did read you whole question and you're asking to do the impossible. I therefore presumed you have a problem with your CD/USB on that machine. I didn't say you had a problem with UEFI now; I said you might later. Please read the whole answer. – ams Jun 3 '13 at 8:39
Okay I see it now. Oh no, my laptop doesn't have any CD drive, my USB HDD cable is broken, WUBI not working.... :( – minmaxavg Jul 12 '13 at 14:30
