Is XP on your C: drive?

If it is not and for example on E: drive then simply replace C: with E: in the command line.

You are inserting the XP cd yes?

yes my xp is on c driver.
and yes i inserted cd.
i thank both of you.
at last is there any way to save files in pc?
my current xp is on driver c.
if i format my pc and load xp on d, will i use my pc again. at least can i save my files?
do you have any oppinion about this?

Is the computer working ok now Irene?

no. not working still same. i didnt format. i scare of losing data. do you know how pc experts fix PCs like mine and save everything. do they use a different software?

What exactly happened when you followed the instructions from Microsoft?

I realise there is a small language barrier here but with you purporting to be a Web Designer I find it hard to understand why this should happen.

i phoned a afriend of mine who sell some pieces of computers and format. i asked if i format driver d. as i have problem with os on driver c, can i reach files on c. he said exactly yes.

i hope he is right. now i am trying this. i will write the result.
