Unable to `factory reset' Mac OS X (10.6.8) snow leopard

A far as the "filesystem verification failed" screenshot, see this thread: https://apple.stackexchange.com/questions/29186/how-to-resolve-error-couldnt-modify-partition-map-because-file-system-verific

The solutions given involve Terminal commands; not sure how comfortable you are with that! Worth a try maybe?

Let me know if this helps. Sorry this is so complicated.

I'm a bit confused xiuli81,

What exactly do you want to do? Do you HAVE a SL install disk handy? (I assume you do if you were running 10.6.8) When you say it doesn't start; do you mean no power or no Operating System? What do you see when you press the power button? And what year/model is your MBP?

Sorry for the confusion. My MBP is 2011 early, 15inch. Unfortunately I don't have the snow leopard 10.6.8 install DVD disk :(

Currently I can not start my MBP normally: when I press "power" botton, it starts with the apple logo but it can not finish the starting process, then it shut down. I was told that I need snow leopard 10.6.8 install disk in order to make it work.

I can find the 10.5.2 OS install disk, will that work for my MBP?

I found this conversation and I know you are expert, so I posted my Qs here

Thank you

I would love to help you, xiuli81, but let's start a new help topic so we don't "hijack" this current thread with CamilaAmoros:)

Start a new topic with your original question and I'll find you (this way, others will see it better too and be able to offer assistance as well).

Thanks!

Early 2011 will only work with the prebundled 10.6.4-5 installer disc that came with it, and not the retail disc or one that came with another Mac. You may be able to clone over target mode from another Mac, but that's really the only hope for that model you have of getting10.7 or later on there if internet recovery firmware was not installed.

Thank you very much!

I could not find the pre-bundled installer disk for this MBP :(

D you mean the later version like 10.7 will probably work?

I start a new topic with xiuli81 so I will not interrupt Camila's questions. Would you please help me in the new topic?

Yeah, let's put this one back out into the open forum in a new thread and see if someone knows what's going on. I'm not particularly adept at deciphering the information in this image!

Good luck, Camila, and I wish we could have solved this one completely!

Also, just found this on the "Leopard OS" community: https://discussions.apple.com/thread/7797787

Maybe this will help.

Is the grey DVD the one that came with that computer? I know those are model/machine specific. If not, you need the white disc that just says "Install DVD" (eBay).
