    Hi all,

    I have a USB thumb drive with Mavericks and I've tried to install 3 times now on my late 2009 iMac (new HDD fitted) and each time it gets to around 1 second to complete then goes back up to a few hours, then back down to a few seconds, etc.

    Any ideas as to what's happening here?

    Hmm... maybe start the install early in the morning, and then leave it run all day.

    Installing from a thumb drive can take a LONG long time.

    That's why, when I reinstalled Mavericks after stupidly installing Yosemite, I chose to install from an actual hard drive (external drive).

    How do you install it from a hard drive? Like, do you have to follow the same procedure as when you create a bootable USB installer?

    I have the OSX installer on an external hard drive. I have two other drives, one SSD, one normal drive. The SSD should be the boot drive. Can I simply open the installer from my external HDD and it will install Mavericks? :)

    I don't want to install from my bootable USB drive because someone told me something is wrong with my OS X. I don't know how you can do something wrong here, but I prefer to be on the safe side.
