So I finally got the time to replace my 250GB HDD in my MBP with the 500GB WD drive. I replaced it, made sure the cables are attached etc. I then put in the install DVD. All works until I get to the screen where I should choose where to install the OS, but that part is blank What can I be doing wrong? Would it help to put in my stock drive and put the 500Gb into an external enclosure and install it onto the external? I'm a bit annoyed right now as I spent 2 hours yesterday trying to buy a T6 (they seem to be pretty damn rare here ) and i spent the whole day working on tons of school projects so I'm damn tired Anyway, any help is appreciated.
