Format SSD and restore TM backup My SSD stopped mounting by itself on boot. So I booted into Single User mode, ran /sbin/mount/ -uw / and exit and it got mounted and I could boot from the SSD. However, after booting all I see is the Guest user and not the admin user. 

However, I have a TM backup and would like to simple erase the entire disk and restore. The issue is I can't erase the disk in Recovery Mode using Disk Utility as it does not get mounted automatically.

What would be the best approach?
Hold down the Command and R keys at startup to start the computer from the Recovery system. The Recovery menu that appears includes the option to restore from a Time Machine backup.


First: delete your SSD drive using Disk Utility. (Mac OS Extended (Journaled))
Second: Choose for Backup from TimeMachine.


And now we wait...

It would be wise to connect your machine using an network cable instead of WiFi.
