I just put Ubuntu 15.04 on a flash drive using pendrivelinux, and when attempting to install it on my computer, it asks for a username and password. What is the default username and password? I haven't been able to find it anywhere on the web. Thanks!

There is no default , you get to choose a user name and password when you install. – Panther May 16 '15 at 04:33

I tried. It's really weird, it expects you to log into the system somehow without even having installed it before. – Anson Savage May 16 '15 at 04:36

2Try ubuntu as both username and password. If that fails - recreate the usb. This sort of thing really shouldn't happen. I installed ubuntu from different usbs on different machines - never had this issue – Sergiy Kolodyazhnyy May 16 '15 at 04:48

@Serg - the OP is running the installer, lol – Panther May 16 '15 at 05:05

@bodhi.zazen yes, i didn't miss that – Sergiy Kolodyazhnyy May 16 '15 at 05:10

2it is not asking you to 'log in', it is asking you to 'create' log-in credentials that you can use form the next time you want to boot into Ubuntu. You can give any username and password you wish to have. – Ron May 16 '15 at 05:20

@Ron , I tried making up my own, and it didn't work. – Anson Savage May 16 '15 at 14:54

@Ron He appears to be at the login screen (somehow). – Tim May 16 '15 at 14:57

possible duplicate of How do I install Ubuntu? See step 12 of the top upvoted answer. There is no default password in the Ubuntu installer; unless you create one in the Ubuntu installer the default password is blank. – karel Jul 29 '15 at 05:47

If it looks like this:
It's asking you to chose your own password. Go for one at lwast 10 characters, (12 is better) that you don't use elsewhere, and has a mix of uppercase (A-Z
), lowercase (a-z
), numbers (0-9
) and punctuation (!"£$%^&*()-=_+{}[]:@~;'#<>?,./¬|\
).
If it looks like this:
The username is ubuntu
and there is no password (just press enter when it asks).

Thank you for the answer. It looks like the second image, and I tired ubuntu without a password, and it said I got it wrong. – Anson Savage May 16 '15 at 14:55

@AnsonSavage Have you already installed ubuntu, or did you click Try Ubuntu? – Tim May 16 '15 at 14:56

I clicked the install ubuntu button. It may be a problem with my outdated bios and current hard drive. In 14.04, it had problems overwriting one of my partitions, so I went to 15.04, and got this far, but couldn't log in using any of the suggested username/password combinations. Thanks. – Anson Savage May 16 '15 at 15:04

1Okay, and you did a restart afterwards? That means you have installed ubuntu. – Tim May 16 '15 at 15:09

So login with the username and password you chose there, at the instalation? – Tim May 16 '15 at 15:30

The thing is, I didn't make a username and password yet. I'll try puttung a new hard drive in and trying again. Thanks. – Anson Savage May 16 '15 at 17:30
I had the same problem. I used a PC with i5-CPU, 64bit, 8GB RAM , a NVIDIA GeForce GTX750 video card, and three monitors. After many hours of testing different situations, I took the basic equipment.
Only the computer with ONLY ONE MONITOR. And you cannot imagine, the installation worked normally. I could define new USER and new PW by myself. I installed Ubuntu 15.10 and then looked for drivers for GTX750, installed und updated the driver and connected three monitors .

Wow! I had a GTX 750 too. Very cool that you figured it out. I switched to Linux Mint just because Ubuntu was giving me so much trouble. Thanks for the answer! – Anson Savage Jun 12 '15 at 23:55
- Open Terminal
sudo su
passwd
- type desired password twice
- change with Ctrl+Alt+F1 to tty1
