Mga boss ask lang how to fix or bypass this error when installing windows 7 home basic to ultimate (natry ko na lahat).

Sinubukan ko na ang way using cmd which is msoobe pra tumuloy pero after na masetup pc name mag eerror ulet sya ng ganon. Nagloloop lang sya don.
Any other way to install windows 7 without affecting files on drive D (partitioned)?
Edit: Fixed. Need lng pla tanggalin flash drive once nagrestart na. Salamat sa mga nagreply.
Thanks mga boss.
