Hi,
recently, my mac book air is getting slow. My book air is 2015 model.
So I decided to reinstall. I pressed command +R after restarted and input internet password.
Then I agreed to install OS X EL Capitan. The message says "select the disk where you want to install osX. But there is no disk.
How can I fix this problem?
Thank you
The solution is to boot macOS Recovery again and use Disk Utility to completely erase the storage device.
Follow these instructions: Erase and reformat a storage device in Disk Utility on Mac - Apple Support.
Pay attention to Steps 3 and 4: Be sure to choose View > Show All Devices. The "Device" in its context refers to the entire storage device, meaning not a volume or partition subordinate to that device.

Can't select the Disc when reinstalling
