Ok... now I am back into WinXP......
Uh after the system starts, and tries to go into the login manager, the screen blinks a few times, then it goes into a command line.
Before that, when I tried to log in to the account I have been using, the screen blinked and brought be back to the log in screen.

How do I get to my graphical desktop using the command line, and do I have to be logged in as root?

If you are at the command line log in prompt. Log in as the user you want and type startx to start your window manager.

Ah hah, thanks!

I remember now that I had once a copy on Mandrake 9.1 on this drive, WinXP destroyed it thought when I had to do a system recovery!!!!!!

AHHHHHH!!!!
Ok, I log in and I type startx.
Then I get an error about a temp file (it goes away to fast to read), then about 3 screens of text about problems, basically a server crash? It says something about a server crash and blah....
But, I still can't enter the desktop!

check out the file /var/log/xfree86.0.log and post the error messages.

DrOzz, do I just type /var/log/xfree86.0.log?

type:
cat /var/log/xfree86.0.log | more

Ok.

Alright, I get this at the bottom:

Could not init font path element unix/:-1, removing from list!

Fatal server error:
Could not open default font 'fixed'

well there could be an easier way around it, and you can wait and see if someone else posts an easier solution, but all i can suggest, is that you specify your font paths manually in your xf86config-4 file located at /etc/X11...that is if they exist in the first place.

How would I go about setting the font paths manually?

well in the xf86config-4 file you will notice at the top a part called:
Section "Files"
you can make entries like so:
RgbPath "/usr/X11R6/lib/X11/rgb"
FontPath "/usr/X11R6/lib/X11/fonts/misc/:unscaled"
FontPath "/usr/X11R6/lib/X11/fonts/local/"

like so...i only typed a couple, cause i don't feel like putting them all...if you navigate to the folder /usr/X11R6/lib/X11/fonts, you will see the different directories for the fonts..
so up above you see i demonstrated the local folder and the misc folder...you can do so for the rest of them that you see in the /usr/X11R6/lib/X11/fonts folder...so you may have like 10 or so entries in your file....
so give it a try and see what happens...
and just cause i think you may ask the question about how you are going to open this xf86config-4 file, i'll just tell you to learn more about text editors....
a basic example of how you would open it is as easy as:
emacs /etc/X11/XF86Config-4
or....
vi /etc/X11/XF86Config-4
emacs and vi are both text editors, the reason why i say read up on text editors, is just for you will know how to save and write to the file, etc, etc....
good luck!

I also had an error about problems with disk space.
Now when I was last in my desktop, I know I had atleast 50 mb left.....

And I got an error like "(root:root) FAILED"
It was another message that appeared too fast to read...
