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

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

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
