I don't know how to restore
Repair your computer option missing from advanced boot menu.
I tried with:
1) REAgentC /disable
2) REAgentC /enable
and similar commands... but they provide errors like:
1) failed operation 2 - file not found
2) failed operation 57 - incorrect parameter
Before posting here, I tried these commands to Windows 8.1 Preview. No problem there, but on Windows 7 Ultimate x64 they don't work as expected.
Anyway, this is the result of REAgentC /info command on Win 7:
Configurazione estesa per Ambiente ripristino

And I attached you two files with the output of bcdedit /enum all /v command + an image of the recovery folder.
Let me know what you think about it.
Best regards.
