When I recently installed Kali Linux on my Windows 7 computer, I completely installed Kali Linux to my computer which deleted all my Windows 7 because I didn't need it. Now Kali Linux is installed on my hard disk on all partitions. I have used it for a while, and now I want to uninstall it completely and reinstall Windows 7.
Now I inserted the Windows 7 disk and tried to install it, but it shows an error that Windows cannot be installed in this partition. I know Kali Linux formatted all my partitions to ext4 which is its own default format, but Windows can be installed to NTFS format, but the Windows installation doesn't give me an option for formatting, so I am stuck here. Please help me find a solution. Remember that Linux and Windows here are not in dual boot.

Disclaimer - before doing anything with partitions, make sure you have good backups
In Windows setup, during the part where you select which partition, select the advanced option, then just delete all the partitions.
You do not have to create any paritions, Windows setup will do that for you. All you need is a blank drive. (Unless you have some special requirements for partitioning, like saving some space for a Linux partition).
