I have updated my MacBook Air 2011 from the App Store to Mavericks but after the installation it doesn't boot up (spinning grey ball). Safemode or a new installation didn't help and verbose mode ends on

"bootcachecontrol: unable to open /var/db/bootcache.playlist: 2 no such file or directory"

I tried

bootcachecontrol -f /var/db/bootcache.playlist generate /dev/rdisk0s2

in single user mode but that returned me a

bootcachecontrol: unable to determine uuid for volume /dev/rdisk0s2

message. Every time I want to access diskutil it ends with

Killed: 9

How can I fix it?
