Hey everyone, i'll get right to it here.

I have 2 operating systems on my computer. both are Windows XP. the one i'm using now works fine and is what im using now. My first windows XP will not open, that is why I have 2. Ok, so Windows XP 1 won't open, it comes to the welcome screen and says "Isass.exe - system error: An Invalid Paramter was passed to a service or function."

Does anyone know what this, and how I can fix it, I just need to get my pictures off of that XP, and then I can get rid of it so I only have 1 operating system. Thanks in advance.

It's an L, not an I.

Take a read through this thread from elsewhere and perhaps your problems will be over. (http://www.geekstogo.com/forum/lsass-exe-system-error-t32803.html)

This kind of problems happen sometimes when threre is a file missing in the system. try to open it in safe mode click F8 when running the computer it may open but some softwares will be missing. i hope this will do it.
