Home to 7 upgrade

Hey guys, I recnelty built my own pc and installed a legit windows xp home, I also bought windows 7 pro 64bit upgrade version, to replace the current windows xp home 32bit.
I bought the upgrade from, I 1st tried to do a clean install but i got this error message "0x80070001" So i tried to custom install, all was going well until it reached the "expanding files" stage, it was stuck on 0% then came up with the error message 0x80070001, My pc rebooted and i found that my OS was unable to run as there was a system32.dll file missing,
I removed the home OS, and reinstalled it, tried upgrading again, but ocne again it failed!
Does anyone know what the problem is?

My pc specs are
AMD Athlon II 3x3ghz
4gb ram DDr3
256mb DDR3 Nivida
boistar mobo TA770e3

Perhaps you have bad media. Try burning the image at the slowest speed possible.

A 64 bit installer cannot be run from a 32 bit environment.

Boot from the Win7 DVD select "Remain Connected to the Internet " to get latest drivers/updates during install,

then Custom install,

use Advanced Drive tools to delete all,

create new partition(s) as you wish,

then format before installing because XP formatting is different from Win7.
