Me and my ex-girlfriend purchased a macbook pro last year, This is the new 13inch MBP with retina display and has no cd drive. I have never used a macbook pro other than to surf the internet. We recently went through a brake up and due to me purchasing the macbook originally we agreed i could take this, She was not happy that i took the MBP however it is by rights mine and therefore had no grounds to keep this from me. However to be as bitter as possible she decided to block me from using the icloud and itunes account and because my knowledge with MBP is very restricted i have no idea what i am doing to reinstall everything fresh.
I went into Disk utils and formatted the Macintosh HD however when i try to reinstall Yosemite from the Recovery Partition it asks for her Login ID and that i no longer have as she changed the password.
Is it possible to totally delete everything from the SSD including recovery partion and either install windows 8.1 pro i bought on disk as i have put this onto USB now, Or could i reinstall Mac OS X again fresh.
To do this i need to format the recovery partition so it removes her Apple ID, She was the most advanced out of us both with mac's and was her who persuaded me to purchase this.
I just want my beloved computer back to normality, i much prefer windows and if possible i would like to 100% Totally format the SSD Clean and start a windows installation from scratch so she can not cause me any more hassle.
She told me she would block my MBP with find my mac if i try and login with her apple id, There is no reason for her to be so evil and i want her ID removed totally and any files she has on my laptop.
I really am no good with macs however i understand how to follow instructions and would be extremely grateful for any help and advice given, She lives in the same State as me and use to go to the same university as me so i copied her university files onto USB and give her these but she still wants to be evil.
