I have finnally installed Fedora 2, dual boot with WinXP. I choosed install boot loader "in the 1st sector of the partition". After successful, it came strainght to Windows XP, on the next boot, without any confirmation!!!
Like I did nothing before).
Oh please, What wrooooong??

The Master Boot Record (MBR) is telling the system to boot into Windows. You need to install a boot loader that is aware of both Linux and Windows into the MBR for it to boot differently (or use a boot disk, but this is highly uncommon these days).

...The latest stable release is Fedora Core 3...

True Still, no reason he couldn't install FC2 if he had the media laying around and later upgrade.

I use WinXP, you know, & Fedora installation give me an oppotunity to choose to load boot loader to erther MBR of WinXP or to the Linux install partition. I did the 2rd and the process complete successful.
So, do you have any other ideas?

I already told you what the problem was. Loading a bootloader to the Linux Install Partition does nothing unless it is "chainloaded" from the MBR, or is the only bootable partition on the disk and the MBR contains nothing.

What your computer is doing is, loading the first partition (probably C: in your case if you say it boots directly to win XP). You need a way to tell the computer to boot the partition you installed Linux on.

The way you have it set up now, the only way to load your linux is by using a boot diskette (not a very good idea, if you don't know what a MBR is, you'd probably get lost in the process, even I would :P)

What you need to do is load linux, using your Rescue CD (comes with Fedora 2, 3, ...) and follow the instructions on screen.) It will lead you to a command prompt.

BE SURE to read the instructions on screen. I believe some things will be new to you, so write them down if you can't remember them. YOU CAN'T mess up anything yet so don't be affraid to experiment a little.

you will have to chroot at one stage, and be sure to do this...

Once you chroot, run the following command:

/sbin/grub-install /dev/hda

This will install GRUB in the MBR of your harddisk. (this should produce no errors)

Then just run reboot to reboot your computer and you should be greeted by a graphical dual boot program, giving you options which OS to boot.

Thanks for you all. I tried to setup this again and everythng is now OK!
However, Linux is so complicated!? The boot process cost much time, and OpenProgram are too low. I'm really getting confused!! Yes, Linux is not easy to use, I think.

If the boot process is taking too long, you're probably starting a bunch of services that you don't need or something is misconfigured. Try figuring out what is taking a long time to start up and try to figure out if they are messages referring to things that even need to be enabled in the first place. If not, turn them off via chkconfig or system-config-services. If they are necessary, post them here and someone can probably help you. If you can't figure it out, try Google and post here if you're still stuck. You probably also should check out the Rute tutorial for a good intro to Linux in general. Finally, please tell us your system specs. FC2 will boot slowly on old slow hardware, naturally.

As for your other question, what do you mean windows open "too low"?

I don't think Linux is particularly harder than Windows. Much different, of course, but not harder. Were you an expert with Windows the first time you booted it? Expect learning Linux to take some time.

I have a SLackware box and it loads up in just below 25 second. I have a web server, MySQL server, and FTP server running by default. With SSH and some other stuff needed for my work. This all happens so fast on a 1800 MHz machine. Just kick all the services off that you do not need. It speeds up the process very much (kudzu is one of them and sendmail...)

Yeah. Maybe you are all right! I'm not ready for using Linux. There are many new things i should learn before. One trouble i have that there are softwares for Windows anywhere, no any this for Linux, except that i have in the CD Fedora. And not much Unicode Font available on system for use, While i have alot that thing on Win. Can I convert this font to Linux Fonts in some way? Or where I can find this kind of font?
Thanks a lot for helping. And sorry for my bad grammar.

A font is a font. You needn't convert it. You can just point linux to it, or copy the fonts to linux partition. Fonts are usually found in C:\Windows\Fonts.

Copy the contents from this directory to your linux partition, or just point to this directory from linux. Here is how you do it with KDE.

Open KDE control center from the K menu. There you will have an option System, and under that option, it should be Font installer. Choose that and add fonts as you like. Then you can use these fonts in any of the applications, that support font choosing. Simple as that. You can have fonts in Linux, the ones you like from Windows.

Good luck!
