Hi. I started to install windows. Did full format for all partitions. When computer was copying files (dark blue screen, long yellow bar) from setup few failed to copy at 97th%, disk is a little bit scratched. Everything kept going fine till the end. At the last step of installation "saving setting" I stuck on. When tryed restart computer and insert another disk of windows to install computer just normaly booted and opened that installation with reading "setup is being restarted" then everything started again and stucked on "saving settings" again. How do I can format hard disk and start with good disk from the beginning?
