cannot find login password

I am grateful for your kind reply. However, there was no username nor
password entered by me when I installed Ubuntu from flash USB drive. At
present Ubuntu is a boot up choice, along with Windows XP Home Edition, on
my hard drive.
I look forward to hearing from you and thank you for your most kind help and
advice.

I don't remember user and password what i can do

You can try this: http://www.psychocats.net/ubuntu/resetpassword

or

To discover your user and restore (change) the password you can:

Start the pc the when you see the GRUB row...

Press ESC.

Press "e" for edit.

Highlight the line that begins kernel ………, and press "e"

Go to the very end of the line, add rw init=/bin/bash

press enter, then press "b" to boot your system.

Your system will boot up to a passwordless root shell.

Type in grep -i 1000 /etc/passwd

The system must show a row with your user name at the start of the row
for example:
danilo:x:1000:1000:ubuntu,,,:/home/danilo:/bin/bash

Here my user is danilo

Then to change your user password type in:

passwd username

or

passwd -d username

change username with your real user

Set your password.

Type in:

reboot

or

reboot -f

Hope this helps

I had to get arround the problem by using the disc. Thanks for your kind consideration of my query.
