Hello!
I am running Macbook Pro (Late 2011) on Sierra osX.
First I repartitioned my HD into single partition(I had Bootcamp). After that I went to encrypt my HD using FileVault and it got stuck for days at around 60%. I think the problem might be something with repartitioning the HD but I see others have problem with encryption as well.
I decided to reformat my HD to make a clean install(I have backed up the system with Time machine) after Disk Utility have failed to repair the disk.
Delete adobe on mac. Now I can not even reformat the HD using Disk Utility from CMD+R mode.
In Disk Utilty I see under Internal 'Apple HDD HTS547575A9E384 Media' under which is greyed out my 'Macintosh HD'. on Disk Images I see 'Apple disk Image Media' which is 2.01 GB and has under it 'OS X Base System'(1.29 GB) with option to eject which does not work. I tried to repair or erase 'Apple HDD HTS547575A9E384 Media' but it does not work. When erasing it says 'Erase process has failed' with details saying 'Couldn't unmount disk - Operation failed'.

What should I do?
Either make the encryption in FileVault to continue the progress which didn't work after reading about it and trying things… or to erase the HD and start a new install from my Time Machine backup. Any help is most welcome!
