I upgraded from XP to 7 a few days back. XP has been wiped off my harddrive and now I'm experiencing difficulty getting windows 7 on. I am upgrading a IBM thinkpad t40, standard specs. I am getting an error code 0x80070570 and its directing me to the CHKDSK utility. When I tried it, it told me that that something couldn't be saved. If more information is needed please do ask.
