installation stuck at detecting file system

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.

Solution 1:

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)

Solution 2:

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.
