Kesulitan pada saat install windows7

[Braincode]

Ane udah mengosongkan Data D dan ane memilih data D sebagi tujuan penginstallan tetapi,pada sata ane klik next kok muncul tulisan kayak gini ya?



"The partition you selected might contain files from a previous Windows installation. If it does, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will not be able to use your previous version of Windows."



Mohon bantuannya please para senior
