Hi
The following has happened:
I tried to upgrade my old MBP Mid 2010 running OS X 10.6.8 (have been using a newer one for some time but needed to make it fit for usage now). I backed everything up, then downloaded the latest version of Mavericks from the store. I also made a bootable usb drive before I proceeded just incase I would feel like making a clean install, however I settled for starting the upgrade process instead and try that out first.
1) Installation starts, then ends with a message of a damaged drive where OS X cannot be installed. I google and find out that this seem to be a fairly often encountered problem.
2) Try to use repair disc (that is accessable from within the failed installation process. Does not work. The drive cannot be repaired (greyed out), neither can it be formatted nor partitioned (gives me message that the disc could not be removed from desktop). I suppose the drive cannot be formatted/partitioned since it is in use.
3) Try various forms of reboots and realize that I do not seem to have any recovery tools that I can boot into. Only choice after holding opt. during boot is the install disc.
4) Resort to my bootable usb. OS X finds it during boot, however, for some reason it goes directly into the install process, it takes 2 sec, then I get the message that install could not be completed and it looks as if what is actually happening is that it tries to complete the ongoing installation process (the upgrade). Error message reads (roughly translated) "The contents of this disk can't be changed. Mac OS X couldn't be installed on this disk".
So... this is where I am stuck. All I want to do is completely erase the hdd so that I get rid of the ongoing (failed) upgrade process. This starts automatically every time I reboot and fails at the exact same moment (after 1 min). How do I stop this?
