No Bootable drive displayed to re-install MAC OS
Trying to re-install MAC OS after erasing hard drive thru Disk Utility. It provides two options to reinstall A) Untitled and B) Update. OS will not install on either of those names. I don't see a Macintosh HD in the disk utility. Attached is what I see instead. I am stuck and would appreciate some guidance from experts. Mine is Intel based 15 inch Mac Book Pro. Thanks a lot
