Guys Good Day.
I am trying to figure out how to reformat our computer using windows 7 but it seems that i did not succeed on my first attempt.
My classmate gave me a dvd, installer and i did the things that the tutorial told me to do but then
when i reached 54% on "expandin window files" i keep on getting this:

windows cannot install required files. the files may be corrupt or missing. Make sure all files required for installation are available and restart the installation Error code: 0x80070570

please help me! and
PS: i dont know if that cd was original or pirated!

As experience has taught me, error 0x80070570 is usually caused by bad ISO's downloaded or bad burns to DVD's. If the DVD was just a burned copy, try burning it again using the slowest possible speed as this usually avoids errors during the process.
