Clean Install question

So my father passed away 3-4 years ago and I was given his 27" imac. My father, being an older "dog", got the imac and then had parallels installed so he could run windows. Yep. Got the imac because it looked cool, but ran it 100% of the time in windows.

So I've always wanted to wipe off the window's partition and change "ownership" name, but just never got around to it. So thought with the new OS, it would be a good time to do that. Problem is, not sure how to wipe everything clean and start anew. I can follow clear instructions, but seems everyplace I look, it kind of says different things. I did upgrade to Mavericks btw.

Any "ultra clean install for dummies" instructions anyone could point me to?

Thanks!

Sorry about your dad. It would be something like
1)Download Yosemite
2) download diskmaker X, insert empty usb 8gb stick or more and create Yosemite usb installer
3) reboot, press alt/option after you hear the long doooooo, go into Yosemite installer
4) click disk utility, format the drive
5) install Yosemite ;)

WHOA. One step everyone forgets...

Sorry about your Dad passing - mine died in Nov. 2011.

Before you wipe anything on that machine - go to http://supportprofile.apple.com using HIS Apple ID and password (and if you don't know the password, use his hopefully-still-active email account to retrieve it).

Then remove this iMac from being registered under his ID. That way, when you do a clean install (yes, I'd clean install 10.9.5 after grabbing his data and wiping the drive, then upgrade to 10.10 after you set all your user preferences - the reason for this will come out in the next couple of days), you will be able to register the iMac under YOUR Apple ID and all will be right with the world.

Sooooo Diskmaker 4.0b2 works OK with the Yosemite GM? You verified this?

I believe i read it does, but it's 4.0b3. I just use terminal though .. it's easier and in the end that's what disk maker x does as well, so..

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction

Where usb disk is named Untitled

Right now Terminal is best since 4.0b2 is problematic, at least I got the error. Until diskmaker comes out with the update for Yosemite final, I would have issues using it. Terminal is so much easier..

DiskMakerX 4b4 is now out and being used

Thanks for the responses. Unfortunately, I don't think there is any way to find out what his apple ID was other than guessing. Even if he was still around, he wouldn't probably know. If I don't do the "unregister" deal, will that prevent me from doing the clean install?

Not at all.

what about some of this stuff that I read about as far as clearing PRAM and the like. Does the clean install do enough that none of those extra steps need to be taken. I understand than clean installs are more those of us that have been traumatized by Windows, but I also find clean installs work better with iOS so I'd like to continue to positive mojo

Nothing really in PRAM you need to clear out. If Internet recovery was ever used on that machine, the wifi password used would be remembered in PRAM, but it does no harm to leave it there. No harm in resetting PRAM either though if it would make you feel better.

Possible borked USB thumb drive/terminal install, but attempting a clean install of Yosemite, I thought everything was going fine until the very end when I got a dark screen upon final boot up with a question mark in a white circle. Dumped the install and use DiskMaker for the clean install and all went well
