I upgraded to Yosemite, worst decision in my life. It was excruciatingly slow, I have an 128GB SSD start up disk, with a 500HDD in a caddy inside, 2.4Ghz processor and 8GB ram. So I back up regularly and apple said to hold cmd + R on start up and restore from time machine. I did this and selected my SSD, but the process was stopped and it said the disk could not be erased. Thereafter i could not startup from the disk and my only option was to restore onto my HDD but obviously I want to install the OSX onto the SSD to ensure my macbook is as quick as possible. I have attached a photo, I would like to format it to be able to restore to it, but so far i can't do anything with it and when I updated osx I think it asked me to encrypt it but disk utility does not see it as encrypted. Thanks in advance.
