I have install fedora core 3 without a user account. Fedora accept it at first, but at the startup it stop at the user acount screen, so i have to setup a user account. How must i do it? My fedora dvd is damaged so I cant run the setup again, or not all of it.

I'm not sure I understand the question. If you're getting a menu to add a user, you should be able to follow that.

An easy way to set up a user account is via the useradd command. For example, at the shell prompt, type:
adduser ibotes

Then, again at the shell, type:
passwd ibotes

This will set up your password.

In order to get to the shell at a new installation, interrupt grub when it boots up. For FC3, you have 3 seconds to do this, by typing the letter "e" (for edit) when grub first prints out the kernel name it is about to boot.

Then, when you get to the next menu, type "e" again. What you want to do is edit the line with the "rhgb quiet"; take out those words and replace them with the word "single". Then boot up. You'll get to single-user mode, and a shell prompt.

Fedora stop booting at the screen where it ask for a user account name and password, since a haven't give one at the setup fedora don't accept anything for a user name or password and don't go any further.

You would have given a root password during the install. So login with the user name of root and whatever password you chose. Then immediately open up a terminal window (I am assuming you're logging into the GUI) and use the adduser command to add a normal user for yourself, e.g. adduser bobby to add a user with login bobby. Then type passwd bobby to set a password for the user. Finally, logout as root and log in as the new user you created.

Thanks to btmiller and dwight1. I have got it right, Fedora work, but not my printer, scanner etc. I have xp on one drive and fedora on another. How do i make a dual boot system. I have to change the booting sequence to the linux or xp drive. I use winfax pro as my fax, do linux have a faxing programlike winfax?
