ForumSnoBorderRK Posted October 31, 2006 Share Posted October 31, 2006 (edited) Partition Map Read Error Problem hey guys, i am seriously having one frustrating partition map problem that i seriously can not fix. So I am trying to install a Mac OS x86 10.4.6, and my PC has the right specs to run this operating system I have Acronis already activated and everything, and i also DO have Norton Partition Magic installed (but i do not use). So I have been following the guide all the way up to the part where it says choose the partition you made from step 2, and change the drop down list to "Mac OS Extended Journaled" then click ERASE. right when its trying to erase (it doesnt even erase it) it says "Erase Failed, Could no read partition map" and i have no idea what to do!!! can someone please help me out? Here i have taken some pictures on my point of view, exactly what im talking about, hope this helps!! ok, so i first go through the beggining installation processes: then, i get to my problem: i do everything right i click the erase tab I choose mac osx journaled i click erase i confirm my erase and in about 5-10 seconds, my problem occurs: and i even did a varification if my partition was working correctly, etc.. i cant seem to find the solution to this problem. much appreciated to all giving time to help me out. thanks -roddy Edited October 31, 2006 by r2 studios Link to comment Share on other sites More sharing options...
beepyou Posted October 31, 2006 Share Posted October 31, 2006 try Erase as MS-Dos first, then erase again OS Extended with Journaled not sure if that will work, but worth a try Link to comment Share on other sites More sharing options...

Linker- Posted October 31, 2006 Share Posted October 31, 2006 do it from the command line with fdisk, create a type AF partition, and ask disk utility to format it with hfs+ Link to comment Share on other sites More sharing options...
ForumSnoBorderRK Posted October 31, 2006 Author Share Posted October 31, 2006 ive tried just about everything inside of the osx installation CD to get this error fixed. the only things i havent worked with too much in the osx installer is the terminals utility. other than that, ive done everything else, so im pretty sure i have to fix this error by using my windows xp operating system. X----------------------------------------------------------------------------------X let me try it with partition magic... Link to comment Share on other sites More sharing options...
ForumSnoBorderRK Posted October 31, 2006 Author Share Posted October 31, 2006 wait a second... ok... so i just opened up partition magic, and i am increasing my unallocated space and defragmenting. then, i am going to use the partition table tool to fix the reading..... does anyone know if this should work? this is about a 1 hour process. *crosses fingers* Link to comment Share on other sites More sharing options...
DudeWTFNo Posted October 31, 2006 Share Posted October 31, 2006 I had this SAME issue and I also used partition magic. My problem was that apple was the 3rd partition (In order: XP, Kubuntu, Apple) and it didnt like that. So I deleted the Linux partition (bring apple to the second primary spot) and then went into partition magic and deleted my apple partition and made a new partition that was fat32 primary, but did NOT label it. In partition magic, the partition read as *.fat32* (or something like that). I think that if you label it, windows automatically associates it with windows and therefore is no longer a 'lone partition'. Just deleting and redoing it without a name, see if that works.

EtherealRemnant Posted October 31, 2006 Share Posted October 31, 2006 Acronis tools... Partition Magic is {censored} for OS X. Get Acronis Disk Manager or whatever it is... I had nothing but problems using Partition Magic and OS X together. Link to comment Share on other sites More sharing options...

meisterk Posted November 2, 2006 Share Posted November 2, 2006 Ok I had the same problem and fixed it. Your partition needs to be primary and possibly the first one on the hard drive. You should create it with any partitioning program like diskpart under XP or partition magic, parted / fdisk under linux whatever. Do it this way: create an unformatted partition (primary) and change it to type 0xAF. Boot the install CD. Run disk utility. Select the partition which should be grayed out (e.g. disk0s1). Go under the erase tab, select MS-DOS, click erase. Then select HFS+, click erase. Exit the disk utility, and Tada! you can install on your new partition. Hope that helps Link to comment Share on other sites More sharing options...

luketc Posted December 19, 2006 Share Posted December 19, 2006 (edited) try using a GParted linux live CD to resize your main partition, then make a new primary fat partition after your main partition with Gparted, PartitionMagic or Acronis Disk Director It shouldn't have anything to do with your hardware http://gparted.sourceforge.net/livecd.php also, look at this thread, dilnalomo's method works great! http://forum.insanelymac.com/index.php?showtopic=11339 I haven't had much success partitioning with acronis, but gparted works great Edited December 19, 2006 by luketc Link to comment Share on other sites More sharing options...
