This question already has an answer here:

I just installed ubuntu-12.04-desktop-i386.iso to my 1GB flash drive via Startup Disk Creator on Ubuntu 12.04. Then, I tried to boot it on my system.

The problem is that it was asking me for username and password.

I tried "ubuntu" with blank password but it didn't work.

The problem has never happened when I installed the same iso file via Universal USB Installer on Windows.

Note: There's no option to make passwords in Startup Disk Creator.

Default username is ubuntu , you are right , but there is no password . – atenz Jul 24 '12 at 16:36
Did you choose a username/password when creating? Try ubuntu:ubuntu... – izx Jul 24 '12 at 16:47
Like izx said, did you select any user and password when you created the live usb? – Rrjrjtlokrthjji Jul 24 '12 at 16:51
Unfortunately there's no option to do that. :( See screenshot above. – Drie Jul 24 '12 at 18:57
if this is a duplicat where is the correct question and answer. 10.04 is different from 12.04 so the 10.04 question IMHO doesn't count – Wolfgang Fahl Feb 11 '14 at 10:12

Try your ubuntu username and password in which you created the .iso
