I am trying to install Ubuntu 14.04.1 (i386-32 bit) dual boot with Windows 7 (home premium 64 bit). I created a USB stick correctly, Checked for md5sum.

After manual option, I created swap, /, /home and proceeded. It gets stuck at detecting file systems.

I tried several times with following options:

  1. enabling wifi (which kept loosing and searching for connection)
  2. wired internet (worked fine (I hope) )
  3. with out internet (I.e without updates)

P.S. I just now un-installed opensuse 11.3 from dual boot with Windows. The memory which was freed from suse is in free space (Light Green) and not unallocated (black). is that a problem?

Alongside I am searching for windows help to convert the green space to black.

  • Have you tried to create /boot and /swap? I'm not really sure but wouldn't hurt to try! – user3101331 Feb 21 '15 at 05:30
  • Welcome to Ask Ubuntu! ;-) Could you please give us a bit more information like: Boot of an Ubuntu liveCD, use the "Try Ubuntu option", go to the dash (the upper left icon) type gparted and take a screenshot of that and post it somewhere and add the link into your question. Please [edit] your question to add this information... – Fabby Feb 22 '15 at 10:56
  • Thank you. Question edited with gparted information. (Sorry the pictures are taken from camera and are not the screenshots.) – MOHINI PANDE Feb 22 '15 at 12:20
  • 8 years later and still the same problems with Ubuntu. I'm so happy I don't need it really... Windows is sooooo easy compared to this sh...t! – Trantor Nov 26 '23 at 19:20
  • I have faced the problem today and I have followed this complete feed and succeeded. I have unmounted my external hard drive first. And then I had gone for the Ubuntu installation by choosing my external hard drive in the installation wizard. Now, I am able to boot Ubuntu from my *external hard disk*. – Dev Anand Sadasivam Jan 19 '24 at 19:26

If I were you, I'd:

  • Take a full system backup
  • Download and burn a DVD of 14.04.2 32 bit version as you seem to have a need for OpenOCD which doesn't seem to like 64-bit versions.
  • boot and follow these instructions,
  • at step 8 take "something else",
  • delete the 200GB /dev/sda6 partition and create a 32GB / and 128 GB /home in ext4 format.
  • leave the rest unallocated (to add to something when that one becomes full somewhere in the future)

    thanks a lot for your answer. my motive for ubuntu was to use OpenOCD. OpenOCD doesnt work well on 64bit versions. Driver problems. so should i carry out this procedure with 32bit image? (i.e. instead of pen drive i'll use live cd).P.S. this partially answers the que, should i still tick & make it green? – MOHINI PANDE Feb 23 '15 at 08:26
  • There you go: edited. Anything else not answered? – Fabby Feb 23 '15 at 09:20
  • :) Happy... thnx i'll try and let you know... every thing answered... :D – MOHINI PANDE Feb 23 '15 at 14:17

I encountered the same problem as you when I tried to install Ubuntu 16.04 and Ubuntu 16.10. It was always stuck on Detecting file systems. I found out that the installation program will try to umount the path /isodevice, but the file is held by kernel, so umount fails.

At last, I opened the terminal and ran the command 

sudo umount -l /isodevice

with success. Then I ran the installation program again. The problem did not occur again.

  • Just to clarify, you want to look for any mounted partitions by running df, and then for whatever items you see there that are partitions of the drive you're trying to install on, run sudo unmount -l DEVIICE_NAME, where DEVICE_NAME is the value in the first column of the output of of df – Isaac Betesh Oct 31 '17 at 12:45

If u stuck in detecting file ... ( cdrom failed ) Restart os , choose try ubuntu

  1. sudo umount -l /isodevice ( terminal )
  2. Reinstall ---> continue --> something else ( if u want to create manual partition )
  3. just using your " free space " ( if it equal 0 , change from your disk NTFS ( sub it )
  4. Finally , u will have free space create 3 partition ( swap , / , /home ) .
  5. Choose your region time and the rest
