Q: Unable to reinstall OS x

If the issues you related to in an earlier thread, were actually resolved and

the mackeeper + AGV other bad software with its  problems fixed, then the

matter of your drive being wiped may be the cause of there being no OS X.

Your previous post implied troubles ahead:

system crash !!! Pl... Help !

A partition on the hard drive for Recovery, if erased, won't be there for the

system to be helped restore from the internet. As a new drive would need

to be correctly prepared for use in Mac, a format & system installed from

the internet. So if you erased the entire drive, that Recovery partition may

be missing. Or the data on the drive so corrupted that it isn't accessible.

You may need to plan on replacing the computer hard drive, of suitable spec

and durable quality. An iFixit.com repair guide for your Mac model is online.

If you had a Time Machine backup or external archive duplicate of your files

in a storage device, that may be accessed later to migrate missing content.

This has essential advice if your computer has later OS X w/o install DVDs:

• OS X: About OS X Recovery - Apple Support

• How to reinstall OS X on your Mac - Apple Support

Which version of OS X is installed by OS X Recovery?

• If you use the Recovery System stored on your startup drive to reinstall OS X, it installs the most recent version of OS X previously installed on this computer.
• If you use Internet Recovery to reinstall OS X, it installs the version of OS X that originally came with your computer. After installation is finished, use the Mac App Store to install related updates or later versions of OS X that you have previously purchased.

As you appear to have a MacBook Pro (not a Mac Pro, since that name is

used by Desktop model; and the MacBook relates to Portable model, this

may be move to the correct ASC discussion based on hardware.

I see no references direct to an OS X version or specific MB/Pro model. As

more information may be needed to help you, please detail product specs

and model build year; also display size helps, because other specs apply.

See if the information in the OS X Recovery link helps make some headway.

Good luck in this matter!

What is the exact model year of your MBP?

Ciao.

Yes.

The braille-like thread you left has my best dexterity unable to follow.

Like a string without measuring knots, so are the detail-less topics.

As stated, the details are lacking; they are essential due to the many

models of product that have a similar name yet can differ quite a bit.

Offer more clues.

I've warmed up my crystal ball, & have incense burning.

(If the computer has a slot load optical drive, it may have shipped

with an OS X install-restore DVD software set; you may need it.)

Oh, I've been chanting, too.

{PS: the Hosts were asked to relocate your Mac from desktop section

to the portable computer section, based on what little info was offered}

My MBP is mid 2009. Why ???

A 2009 MBP came with Leopard installation disks which will allow you to install an OSX and get the MBP functional again.  You say your friend lost your original disks?  I suggest that you tell your friend to get you replacements by contacting Apple Customer Support.  He will need your MBPs EXACT serial number which is on the bottom of the case.

If you want to install a newer OSX, you will need to install Snow Leopard.  The retail Snow Leopard disk has been discontinued by Apple so you will have to find another source.  Amazon is selling them.  The Snow Leopard combo update is still available online.  By running that, you will have 10.6.8 installed allowing you to install any of the later OSXs.
