Mac starts and restarts

[Shark1217]

When I select mac os x from the os selector it does it thing and then comes back to the os selector. There is nothing to do.

I have the same problem.

I usuall press a key, and then type "-F" (without quotes) in the boot options.

[U.C.]

press F8 Instantly after selecting OSX. Now select the OSX drive.

 

If u have a proper fix for this, pls tell me

[MarcConnor]

I have a proper fix for it.

Just follow the steps provided below.

 

1) In mac, browse to your mac drive/partition. Then, go to Library -> Preferences > com.apple.Boot.plist, open it up in TextWrangler.

 

2) Once there, delete each and every one of the

<key>x</key>

<string>x</string>

 

When you see no more of them, you should have

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"

"http://www.apple.com/DTDs/PropertyList-1.0.dtd">'>http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

</dict>

</plist>

 

4) In there, add these two things

<key>Boot Graphics</key>

<string>Yes</string>

<key>Timeout</key>

<string>3</string>

 

When you're done, you should have:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"

"http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Boot Graphics</key>

<string>Yes</string>

<key>Timeout</key>

<string>3</string>

</dict>

</plist>

 

5) Once that's done, boot into XP (Or your windows OS), and go to

 

Start > Run > diskpart

 

In diskpart, type in "list disk" (No quotes). Choose your disk by "select disk #" (Again, no quotes, # is the number of your disk) Once there, list the partitions, and look for the one with its type as Unknown. Note its number. Now type:

 

select partition #

set active

 

(# is the number of the partition).

 

And you're done.

Reboot and your good to go.
