If you don't like passwords then Linux may not be for you. Security is
considered to be a top priority with Linux. This means that you need to not only
have a password but to input it anytime you make changes to the system. If you
don't want this then you should stick with Windows.

However, the benefits outweigh the annoyance factor when you consider: you have
no viruses, trojans or malware to worry about. You don't even have to run
anti-virus software if you don't want to. You can install programmes with peace
of mind that they are virus free. Your homepage does not get hijacked and you
never get things popping up when you don't expect them. This is why you give
your permission which is what the password is all about.

Your system files are kept apart from user files. There are different levels of
permissions for each. It is a whole different way of looking at computer usage.
For this reason Linux is more secure than either Vista or OS/X. It is a small
price to pay and you get used to it quickly. Most of us don't blink an eye and
when it does not ask for our permission we get annoyed.

The easiest solution to your problem is to remove Ubuntu in Windows from your
Control Panel and re-install it. This time think about your password carefully.
It should have meaning to you but not to anyone else so that it is easy to
remember. Passwords are case sensitive. They should be at least 8 characters
long and have numbers and letters. You can try to go into single mode and reset
the password but that is hard for a newbie.

This may make you feel a bit uncomfortable because it takes you to a command
prompt, but it should work if you feel like giving it a try. Grub is the menu
right after the Windows bootmanager which has Windows first and ubuntu second.
Right after this disappears when you choose Ubuntu from the menu, grub will
display with Ubuntu as the first item. Don't wait too long as it will begin to
boot after ten seconds or so. Just press e when it is on the first line of the
grub menu.

You should develop a method for passwords. Once you have this established then
you can use it with anything For example, you could take the first two letters
of the site or operating system plus add the month and year of your birthdate
and finish with the two last letters of your middle name. The key is to be
consistent. So a password for Ubuntu could look like UB0566rd for someone using
Ubuntu with a birthday of May, 1966 and with the middle name Richard. Notice the
use of capitals. You can mix them as long as you always mix them in the same
way. The Windows password for this person would be WI0566rd and the Gmail
password would be GM0566rd.

Using a similar method I have used the same password for years but it changes
with the site or OS and I never forget it. What I did is took a name such as a
pet name and changed it so the vowels become numbers that resemble them (I aways
use the same ones such as 1 for and zero for o) and then I append the site or
OS name to give something like this R0v3r&Ub for Rover and Ubuntu. The
possiblities are endless which is what makes passwords hard to crack.
