Acer Aspire 9500 xp booting problems

First of all i would like to greet everyone in this comunity. Up till now i just read the threads when having problems but i stumbled upon something that i really cant get to the bottom of.

Ok so last year i formated my acer 9500 laptop and got a normal home win xp. A couple of days ago i got a hold of my original acer system cds and i decided to restore my system back. Everything went well until the install finished; I was in windows and the first time i restarted the laptop it didnt boot back in win xp. When its about to start booting windows it stops and all i get is a black screen and a flickering white small line on the top line. I tried reinstalling the original system again and the same thing happends; after the first restart it doesnt want to boot xp.

I started reading forums and found out that if i press alt+f10 it might fix the problem. It worked, if i press alt f10 before it reaches the black screen it loads into xp. This is the only way i can load it. As i read i got the feeling i might have messed up my MBR. Im not sure how this all works but i have a hunch that my laptop doenst know where my xp is when its supposed to load it and by pressing alt f10 it somehow temporarly fixes that. Is there any way to permanently fix this ? Some pple said that if i ran a normal non-acer win xp cd and ran some sort of MBR fix it might solve my problems. Im getting a cd from a friend in a couple of days . Is there any other way i can fix my notebook before then ? Its not a big deal if i have to press alt f10 everytime i restart but its annoying and i have a hunch ill run into trouble later on.


Thanks in advance for any suggestions !
