hi, I'm a nem member on this forum and I'm french

(so sorry for my bad english

) I've register myself on this forum to download a new bootscreen for my computer. So I've dowload one and I followed the instructions which were on the file "read me" (I've download "bootxp") and when I choose "set as my bootscreen" the program told me the version of my bootscreen were not valid (or a thing similar) and after it told me my new bootscreen was ok. So I rebooted my computer and before launch the system my computer asked me which system I wanted to use (windows xp or windows xp

), and it never asked me that before

, so I choose the first "windows xp" and it rebooted as usual. and the new bootscreen was on, but the "charging bar" (the thing that go from left to right) was on the middle of the screen (I had replace it before reboot).
first I hope you understood my message

and after I'd like you to help me please

(why I have a problem with bootxp, and how delete the message that ask me which system I want to use)
thanks and goodbye all
ps : last thing, am I a good english speaker ? looool
