I partition my hard drive with acronis FAT 32 primary

 

and during startup it says unable to mount...

 

then when i erase volume format to mac os extended (journaled) (disk utility)

 

it says Could not read partition map

 

and mac os x won't install

 

it changes the name of the partition from "Mac OS X" to "diskOs2"

Use Disk utility then use erase feature select unix when that is done erase again and select MAC journaled you should then be able to mount.

When you use your DVD to boot to OSX you will see on the left side of the screen in the menue bar an item named utillities, select that then select disk utilities, you will then see the disk utillity the first tab is first aid the second tab is erase select erase next select which partition you wish to format in the left side of disk utillites on the right side or about the middle you will see a drop down box select Unix then select erase when that erase is done got to first aid ans select verify disk when that is done go back to erase tab select your partiton then from the drop down box select MAC Journaled when that is done close disk utillity and select continue from the install dialouge when you get to the select drive there should be a green arrow on your newly formated drive.Do NOT forget to select customize in the type of install dialouge. I hope this helps.

Your boot sector is corrupted. I ran into this with a "B0 Error" and this is how I fixed it:

 

I grabbed my XP cd (Win2k should do also) and booted off the cd. Go through the motions as if you're going to install Windows. When it gets to the partition part, delete the partition and create a new one. Select the default (NTFS) let Windows setup format it, copy files to disk and reboot.

 

Here's the part where we break away from Windows -- Once you see that Windows is going to boot up to continue setup, shut the computer down (hold power button for 10 sec most comps). Start it back up and remove the Windows cd and put back your OS X DVD.

 

Boot into OS X setup. Once up, use the Disk Utility to erase and format THE PARTITION *NOT* THE DRIVE! When that's complete, click on repair and let it check/ repair the disk. Usually it will tell you there's nothing to repair, which is what we want.

 

Quit Disk Utility and Install OS X (make sure you click the "Custom" button to select the patch you need for your hardware (SSE2, SSE3, etc)).

 

Reboot and "X" should start with no problems.

 

Good Luck!

You could have just used the fixboot cmd from the recovery console. Will look into this method later, since I also have problems mounting my partition.
