no hard drive visible for a time machine recovery

Hi All,

Just want to thank everyone in advance. So a few days ago, my macbook stopped working properly. Only thing I can access is my time machine feature ( when booting up and holding hot keys). But to my dissapointment, it doesnt detect any of my regular hard disks storages so I can make a copy from to a usb.

There are two options, disk0(which have no active entries) and MacOS Base System (doesnt look my hard drive , as it has only 2GB of space)

So basically no backup source to get a copy from. When i get to the backup source window, it is empty.

I am not sure, where to go from here, are all of my files lost?

Regards,

Tom
