I never made a backup on my Macbook pro, and recently broke it beyond repair. Don't know how I managed it, but the whole Macbook Operating system is deleted and overridden by Windows, and theirs some formatting error when I try to re-install Lion. My ONLY option is to backup my laptop, however I never made a backup (I'm an idiot, I know). Is it at all possible for me to use my mothers Macbook Pro to backup her mac and for me to use that backup? I'm a bit of an amateur at this, so forgive me for asking but, Our hard-drive is a SeaGate wireless hard drive (1 terabyte) , can I backup to that and access it from my mac which has no OS. Also doing anything through Windows is impossible, I installed Windows Xp 2002, thinking it would be good enough to use, however it cant even connect to my wireless.. Thanks for your time, I appreciate it.
