Hi,
I was trying to reset my MacBook Air 15 in order to sell it. I got all my files saved but I've accidentally deleted Macintosh HD.
=> when I was trying to reinstall Mac OS, there is no disk to select...
How can I solve this ?
Thanks,
MacBook Air
This will happen subsequent to upgrading macOS to a version that reformats a startup disk to use APFS, which previous systems do not recognize: File system formats available in Disk Utility on Mac - Apple Support.
In Disk Utility, select the storage device indicated below, then erase the disk.
Choose GUID Partition Map and Mac OS Extended (Journaled).
Then, you will be able to reinstall Yosemite.

You may actually need to partition & format the SSD instead by using the instructions in this article since Yosemite works a bit differently than newer versions of macOS/Disk Utility:

No more Macintosh HD...
