Not an answer, but a step forward maybe:
I hope that USB flash drive is a "Live CD", if it is, boot it in 'Try it out'-mode and then open a bash/Terminal with e.g. CTRL+ALT+T
In there, at the $
prompt, type
lsblk
The response should look similar to this:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 232,9G 0 disk
├─sda1 8:1 0 487M 0 part /boot/efi
├─sda2 8:2 0 200,5G 0 part /
└─sda3 8:3 0 32G 0 part [SWAP]
...
sdg 8:96 1 1,9G 0 disk
sr0 11:0 1 1024M 0 rom
edit: added sdg and sr0 above
sdg is how an not yet partitioned device looks. It may have a partition *table* though.
sr0 is a CD/DVD R/W device
With partitions added to the 1.9GB microSD card, in card reader:
sdg 8:96 1 1,9G 0 disk
├─sdg1 8:97 1 1,8G 0 part
└─sdg2 8:98 1 99M 0 part
From comment below:
It looks as if you have an
1.9G
disk - you need in the range of 6-10G when the install of 14.04 LTS is
finished - judging from the content of
my /
.
You need to use 'gparted' to remove what there is now - while you're at it you will see what gparted says about the disk.
one more edit
sudo dd if=/dev/zero of=/dev/sdg bs=512 count=1
would wipe ALL partition data from the 1.9GB microSD card above. IMPORTAN NOTE If you attempt this - be VERY SURE THAT YOU TYPE WHAT YOU SHOULD - it will wipe the disk you type the name of - which might be something else than the one you intended.
In the end, if it differs from what actually is, and you cannot tweak it to be correct - then the disk is suspect and might be faulty.
...
If you can make it work that way, you might try defining the partitions yourself:
Make /swap (4-8G? Depending on your RAM) and /boot (1-2G), the rest for /
- what is above is my setup on a "256G" SSD-disk.
I have a separate disk mounted at /home for all my data, but that isn't necessary for a 'low data space' installation.
