What do I have to do after installing.

I installed Ubuntu 8.10 on my pc, along with Windows XP. The first time I runned it, I got some sort of Command Prompt. The place where you type says "grub:". Can anyone help please?

You probably installed grub not the right way. Does it says any other thing at boot like GRUB boot error? For the manual of GRUB look at this http://www.gnu.org/software/grub/manual/grub.html To boot windows try this commands and let me know what happens

rootnoverify (hd0,0)
chainloader +1
makeactive
boot

To boot Ubuntu type find /vmlinuz it should write something like (hdX,Y), where X and Y are numbers then type

root (hdX,Y)
kernel /vmlinuz
initrd /initrd
boot

May you should replace initrd with initramfs. Any way type 'initrd /ini' then press tab. This should complete the command.

Try typing in ``` startx
