    I have just bought a mid 2010 MBP 15" from work at a good price. It has Mavricks installed at the moment but previously shipped with an earlier system which I suspect came with an install DVD. I no longer have the DVD.

    I would like to do a clean install but if I do this, would I need the original system DVD to complete the system boot after erasing the Hard Drive? I can't remember what version of OSX it came with but it might have been Leopard or Snow Leopard? It certainly wasn't Lion.

    Can anyone advise me how I could accomplish what I want without the original DVD?

    you can do a clean install of Mavericks if you want

    go to the store and download the Mavericks Install DMG

    when its done downloading it will prompt to install, exit out of the install screen

    now download diskmakerX

    diskmakerX needs a 8GB USB stick

    when you run diskmakerX it will ask you what OS choose Mavericks, it will detect the file it downloaded, than chose the target(USB drive) and it will make a Homer Simpson WhooHooo sound when its done

    now that you have a bootable USB of mavericks you are ready for a clean install

    obviously backup you data cause a clean install delete everything

    when you ready you plug in the USB and restart MBP, when you hear the chime hold option key and you will be brought to a screen with boot choices, pick the USB OSX Mavericks one

    now you can use disk utility to erase and format the hard drive

    once thats done pick install OSX and then you will have a clean install

    Thank you for your reply. I apologise but I wasn't clear enough in my first post. I want to also change the registration of this computer to my own Apple ID. Currently it has my workplace ID on it and I believe I can only do this if I get an original DVD of the OS it shipped with. I am not sure if I can download this using internet restore. I suspect not because it probably shipped with Snow Leopard.

    Sorry again for my inadequate post in the first place and thank you for your help

    First login to the App Store and "purchase" Mavericks with your own AppleID. Now command-r boot to recovery and from there start Disk Utility and erase Macintosh HD. Then quit Disk Utility and click reinstall OS. You will be asked for your AppleID. Then the OS will download from Apple's servers and install. At the end you can setup a new account for yourself with your AppleID.

    Once you are done, make a Time Machine backup of the new system so you can use this to restore if you ever need to.

    Of course doing this will remove any data on the machine, so make sure you have a data backup somewhere.

    Thanks folks. I had been told I'd need to reinsallt the original OS that came with the machine as it wasn't licensed to me and I'd lost that disk. Anyway, I did the restore as it was running mavericks already and I have mavericks on my other macs with my Apple ID. All went well and things are running with my ID now

    Thanks again
