need help I screwed my macbook so bad thiere is one drive and no partitions, please read below So...I somehow messed up my macbook Pro model 1502 raetina 13" Late 2013, core i5, 4GB. I wanted to clean install High Sierra.  Long story short I now have a macbook with one, yes one, there is no base drive, there are no partitions at all.  I can't seem to find anywhere to download an installable version of high sierra anywhere.  Is it possible to make a boot drive from the macos that I can boot with to erase my one drive?  I'm sure there is a lot I don't know nor have thought of.  I greately appreciate any help you can offer
This is a duplicate of many questions where you boot to Recovery and re-partition / re-download an installer and set up a new OS.

You can bring another bootable volume to the Mac as well or bring a bootable installer or just a drive with a local recovery partition as well. You don't have to erase anything - main thing is to get another OS running so you can decide if you need to backup or do data recovery. If you have a full backup or can walk away from all the data - just erase the volume and set up a new OS.


Can&#39;t start Mac in recovery mode - only get folder with question mark instead
