"GUID partition table scheme" Can't install snow leopard on my mbp.

I have a mbp that is partitioned as half mac, half XP. I put in the snow leopard CD and came up with an error that said I could not istall snow leopard because my partition did not fit the "GUID partition table scheme". I followed the menues to the partition section of the disk utility. From there, I don't know what to do. I can't click on the "options" button to change to the GUILD thing. Do I need to repartition my entire mbp? Will this erase my other partition? And will it delete all my data? Any suggestions on what to do???

GUID partition table (GPT) or map is a set of instructions at the very begining of a storage drive to tell the hardware what partitions and formats are where on the drive.
A Intel Mac now requires a GPT to boot OS X as it uses EFI (Extensible Firmware Interface) which is a software firmware in a hidden EFI partition on the boot drive designed originally for copy protection by Intel. EFI loads into memory before OS X does, which can be seen if you have verbose mode activated upon boot time.
Setting up the boot drive with a GUID Partiton table WILL require backing up of all data off the machine and a complete erasure of ALL partitions on the drive, which includes ALL data, programs, operating systems and files not backed up off the machine previously.
Since a partition map is basically road directions, when it's destroyed so does go the partitions.
Also since you will be fresh installing 10.6, your free iLife won't tag along,, however you can erase/install 10.5 first then upgrade to 10.6 (no BootCamp) and that shoudl work.
Unfortunatly Mac's only now support Windows 7 in Bootcamp, however Windows 7 Pro (and above) will run XP programs natively or via free virtual machine XP downloaded from Microsoft, however since it's really not native, 3D games etc likely won't run very well.
If your not familiar or willing to take a chance, then I suggest you have someone else upgrade that machine.

Hi all,
I am on vacantion at on of my cousins and I realy need to reinstall all on my mbp, but i can`t do it because my osx install dvd is home.
My cousin has a imac and i`ve tried to install from his dvd but my mbp doesn`t wanna bot from his dvd, the installer doesn`t open. .. weird?
I have tried everything:
I`ve tried: in the instaler, click Utilities and then click restart -
Restart my com while holding down the C
I don`t want to remote install OSX, it should work with DVD, is there a problem with my mbp?
What can i do?
my config:
MacBookPro6,1
CPU 2.8 i7

Thanks a lot.

You cannot use an iMac original installer disc on a MBP. You either need your installer discs or you need to purchase a new copy of Snow Leopard locally provided it installs a version later than the one that was originally installed on your computer when it was received.

HT5225 "This disc does not use the GUID Partition Table Scheme...". I keep getting this message when I try to install OSXLion. It has something to do with a repair Apple performed last year. I use a 17" MacBookPro. Any suggestions?

"This disc does not use the GUID Partition Table Scheme. Use Disc Utility to change the partition scheme". I keep getting this message when I try to install OSX Lion so that I can upgrade my 17" MacBookPro to move to iCloud. My harddrive was replaced last year by Apple because of a fault by the manufacturer and I think this is the cause of the problem. What can I do so that I don't lose my content.

When you click the partion tab. There is option on the bottom of the window. Click on that there there are these options.

This disk doesn't use the GUID Partition table scheme.

When I Install the Lion. It is stuck.
Lion This disk doesn’t use the GUID Partition table scheme.Use disk Utility to change the partition scheme.Select the disk,choose the Partition tab,select the Volume Scheme and then click Options.
The last step has problem.
I can not click Options.

In order to repartition the startup drive you will have to boot from your Snow Leopard DVD, select Utilities and then Disk Utility. YOU MUST ERASE YOUR DISK TO CHANGE THE PARTITION TABLE. The good news is that I see you have a Time Machine backup. Make sure that your backup is current before you erase your startup disk.
Even before doing this, save a copy of the Lion installer (it is in the Applications folder) onto an external device. Your external hard drive is a good spot; it won't interfere with your Time Machine backup. This will prevent you from having to download the installer again.
The easiest way to proceed after making sure your Time Machine backup is current, saving a copy of the Lion installer, and repartitioning your startup disk, is to reinstall Snow Leopard on your newly partitioned disk. This will take a little longer but it is simple and is fully supported by Apple. Once that is done and you are running Snow Leopard on your startup disk again, run the Lion installer from whereever you saved it, and then restore your files and settings from your Time Machine backup during the install process.
There is an unsupported procedure for making a bootable Lion DVD, but it is more complex and is not supported by Apple. If you are uncomfortable with any of this and have access to an Apple Store, make an appointment at the Genius Bar and they can help you through the process.

How do I get my mac partition to use GUID partition Table Scheme?

I just bought the upgrade for Mountain Lion on my Macbook pro (Mac OS X 10.6.8). I went to install it and i had partitioned my internal harddrive with bootcamp to run windows 7. I went to select the Macintosh partition and it says that disk does not use the GUID partition Table scheme, and it will not let me select it for the upgrade. It says I have to use Disk Utility but I cant seem to figure out how to get it so I can upgrade it to mountain lion. Please help and thank you for your time
P.S. - Let me know if you need more information to get to the conclusion to this problem.

Bonjour is built-in to OS X. No download is needed.
Safari has a Bonjour browser which you can activate by opening Safari Preferences, selecting Advanced and enabling one of the Bonjour entries to add a Bookmark. If you then select the Bookmark, all devices on your local network that are advertising themselves with Bonjour will be shown.
With regards to the Air not finding the printer attached via USB, you can open System Information and select USB in the left column. The top right pane will show all the USB busses on the Air and if the printer and its USB cable are working correctly, then the printer should be listed under one of the USB busses. Do you see it? If not, try another USB printer cable.

Can't install snow leopard on partition after upgrading to lion

I rushed out too early to install Lion via Apple Apps store. Now, I realize that Rosetta is gone and so are my options to use older apps. As I was reading on the web and Apple Support, I have tried various things and get a window saying that I can't install snow leopard.
I have never partition my hard drive, but using disk utility I created a partition called "Snow Leopard." It divided my HD in half which is okay. I closed the disk utility window, rebooted holding down the "C" key, and saw the OS X Install DVD. When I select it a window pops up saying, "You can't use this version of the appl inst Mac OS X with this version of Mac OS X. You have installed Mac OS X 23.1.1."
Before downloading lion, I made a backup of my existing HD using Time Machine to an external HD. When I open up a saved version dated a month ago, I see that the applications that were working in snow leopard now have the icon circle saying that it is not supported by lion. This is strange since I used Time Machine to back up my HD, then turned off the app before downloading lion. Even older versions saved on the external HD show the circle.
I read about lion and the "Recovery HD," but when I hold down the Command-R key nothing happens when I restart my computer. It also talks about using the option key but that does not work. It talks about reinstalling lion using this system, but I don't see it working.
How can I install snow leopard on my new partition, then I would go to "Software Updates," to get the latest version, or use one of the versions on my external HD to have both operating system.
Thanks,
DaisyMay

Hi Scottiemn,
As I was trying different things to make a partition on my HD, I made notes as to what I did, and I finally got it to work. I will try to explain what I did.
Before installing “Lion,” I backed up Snow Leopard using Time Machine to my external Seagate HD. I installed “Lion,” and found out that I could not use some of my old apps, so I did the following.
Since I am running “Lion,” I opened up disk utility and selected my MacHD (1TB), then I selected partition, and it showed “Macintosh HD” under the partition information name. I believe I selected the plus, + and it divided my HD space in half, and I named it Snow Leopard.
I then installed the Snow Leopard DVD, and restarted my computer holding down the “C” key, I held it down for about 30 seconds or more and then took my finger off of the key. As I waited I finally saw that I was on the install DVD, and on the top menu bar I saw “Utilities.” I had my external Seagate HD mounted on my desk top before I restarted my computer, I selected the “Utilities,” on the menu bar and it gave me the option to back up from Time Machine, I selected my external Seagate HD to the newly created partition I named Snow Leopard and I said “Yes.” I followed the instructions and after it was done, I went to the menu bar and selected System Preferences, System, Startup Disk, and selected to start up with Snow Leopard. On my desktop, I can see two Hard Drives, one is Macintosh HD with “Lion,” and the other is Snow Leopard.
Then, I started up my computer and I was on the Snow Leopard partition and I saw all of my apps working. I then went back to the menu bar and selected System Preferences, System, Startup Disk, and selected to start up with “Lion,” and restarted my computer and I was running “Lion.”
I am not sure why I was not able to use the DVD of SL before, but somehow I got it to work, and I hope that I have explained what I did above.
One thing, when I installed “Lion,” from the app store, I did not make a bootable DVD of the application. I went back to the app store and downloaded “Lion” again and kept it in the dock until I got Snow Leopard to work. I burned a DVD of “Lion,” and so I have a backup of it.
Since my Seagate HD has only 250 GB of space and it is an EIDE HD 7,200 rpm using an OWC Mercury Elite FW400/USB2 with the Oxford chipset 911 enclosure which I bought in 2008, I decided that since I now have my 27 inch iMac quad core i5 with 1TB that I needed a larger hard drive.
I researched the web and decided to go back to OWC and just bought a 2.0TB OWC Mercury Elite Pro “Quad Interface” 64MB with eSATA/FW800/FW400/USB2.0 with 7,200 rpm speed for $219.00. I partitioned it for Time Machine, and Carbon Copy Cloner.
I ran Time Machine, and both partitions “Lion, and Snow Leopard” are on the Time Machine partition and both HD’s are under the Carbon Copy Cloner.
I am self taught on my many iMac’s over the years, and I go to the forums to ask questions and follow the helpful hints to resolve my problems. I carefully try different things and write down what I did so I don’t repeat things.
I hope that I have explained what I did, and hopefully it will work for you.
When I want to run SL, I select in the System Preferences to start up from that disk, when I want to run Lion, I go back and select that and start up my computer running Lion.
Since I have many old apps that Rosetta uses to open them up in SL I wanted to keep that operating system. I will go back now that I have everything working and see if I really need them. I won’t rush to remove my SL partition that I created, but in time if I don’t need the older apps then I may clean out my system and just run Lion.
I run Lion now all of the time, but when I need to go back to SL, I now have the option.
Good Luck,
DaisyMay

Lion This disk doesn't use the GUID partition table scheme

Hi I have downloaded and began running the installation but it says "This disk doesn't use the GUID partition table scheme", any ideas?! Running latest version of OSX 10.6.8
Thanks in advance!

ok, sorry if I offended you for wrong.
I did not knew Apple ships MBR partitioned disks or has official support for doing so. I always see Windows-PCs with that scheme ( Linux supports mbr and guid just like osx ) .
Of course I know that Disk Utility offers three options : GUID or MBR or Apple partition map for ppc devices.
Lion needs GUID, so a reformat is absolutely necessary for those that have one of the others.
Again sorry.

Can't install Snow Leopard on a MacBook

Hi guys...
A friend of mine brought me his Macbook to fix it because the hard drive was making sounds and now won't boot.
The drive in fact is bad, it barely mount, makes noises, etc.
I've replaced the internal hard drive for a Toshiba 320gb SATA 3.
The thing is that apparently the DVD doesn't recognize my drive and of course, i can't install Snow Leopard.
My question is, is this a problem with the new drive?. I believe that being a SATA3 could be causing the problem.
Second question... Can i install Snow Leopard (somehow) using my Mac mini?
Thanks so much and i hope you can help me.
Regards.
Francisco.

Hi!!
>I've used another internal hard drive and installs correctly<
Using the DVD installer?
Yes
So it boots with another hard drive in there but ejects when you put the Toshiba in there?
Yes but it only make sense if the DVD would create a temporary partition or something in order to install the OS.
>Could it be that the drive is SATA3? <
Even so it would be downwards compatible.
I though so too
>or maybe the hd is bad?<
That would make more sense.
I'm going to clone the installation that went OK in order to see if it's actually my internal drive the problem.
Could it be the manufacturer?
Thanks so much and i'll let you know.
Regards.
Francisco.

Can I install snow leopard on an external hard drive so I can run quicken 2006, and put snow leopard on my imac harddrive

Can I install snow leopard on an external hard drive in order to run my quicken 2006, and install lion on the hard drive of my imac?

You don't need to erase the drive and repartition from scratch. You may be able to add a second partition on the fly. The caveat here is that once you do that you cannot create a Windows partition using Boot Camp. Of course if you have no plans for Boot Camp then it isn't relevant.
To create a second partition on your existing startup volume:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Now, you cannot add a new partition that exceeds the amount of contiguous free space at the end of the drive. Disk Utility will fail to add the partition if it cannot find sufficient contiguous free space. If that's the case then you will need to follow your state outline - backup, boot from clone, erase internal, repartition internal, restore backup to one of the partitions (or both in your case.)

How do I make a partition on my HD to install Snow Leopard (Lion is on my HD now)?

I have been an Apple fan since the first Mac in 1984 and have used every version of the OS since then. Until Lion, I thought each was an improvement on the previous. I have had so many random and annoying problems since installing Lion on my (early 2011) MBP with 8 GB of RAM that I thought I'd make a separate partition on my HD and install Snow Leopard there, gradually moving back to that version. I tried disk utilities first, but the mount point for that partition was /Volumes, not root (/). I then tried Boot Camp, and succeeded in making a partition that mounts at root, I reformatted it with disk utilities (to MacOS HFS with journaling), but the Snow Leopard install DVD cannot find this. Stuck!
Btw, the most recent Lion OOPS! was that Address Book refused to start on my user space. I tried from another user and it worked there, but not on my home user. After trying everything I could think of, I finally booted in safe mode, and then Address Book worked. When I rebooted normally, Address Book still worked. Go figure!

Can I install Snow Leopard now?

I previously asked a similar question, but can I install Snow Leopard 10.6.3 in a VM, update it to 10.6.8, and then copy files to a partition on my hard drive? I have 10.6.3 retail version. (mid 2011 iMac)

How To Run Snow Leopard On A New Mac
This does not apply to new Mac Minis or MacBook Airs. When newer models are introduced that also require Lion for hardware support, the techniques described below will no longer work with the possible exception of using Parallels 7.
What has to be done:
1. Create a new partition on the hard drive.
2. Get a clone of a 10.6.8 Snow Leopard system. Put the cloned Snow Leopard
        system onto the new partition.
Step One: Create a new partition on the hard drive
To resize the drive and create a new partition do the following:
1. Restart the computer and after the chime press and hold down the
               COMMAND and R keys until the menu screen appears. Alternatively, restart
               the computer and after the chime press and hold down the OPTION key until
               the boot manager screen appears. Select the Recovery HD and click on the
               downward pointing arrow button.
          After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3.           In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4.           Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Step Two: Obtain a clone of a Snow Leopard system:
You will need access to a Mac already running Snow Leopard. You will need a 16 GB USB flash drive or an external hard drive to which you can clone the Snow Leopard system from the Mac that has Snow Leopard installed. Alternatives are:
Option One:
Install a new Snow Leopard system onto a USB flash drive. Boot the Mac used for installing with the USB flash drive. Update the flash drive system to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard. Verify that you can boot the Mac with the USB flash drive.
Take the USB flash drive to your new Mac and try booting from it. If it works then clone the system from the flash drive to the newly made partition:
          Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination
      entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new partition on the internal drive. Source means the USB
flash drive.
Option Two:
If you have a large enough external drive you can erase and use, then it would be easier to just clone the entire Snow Leopard system from the source Mac computer to the external drive.
          Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination
      entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external drive. Source means the Snow Leopard Mac's
internal drive.
After cloning verify that it will boot the source Mac. If so then take the external drive to your new Mac boot with it. If all is well then restore the clone to the new partition on your new Mac:
          Restore the clone using Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination
      entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new partition on the internal drive. Source means the external drive.
You will need a retail copy of Snow Leopard. If you need to purchase Snow Leopard contact Customer Service: Contacting Apple for support and service. The price is $29.00 plus tax. You will receive physical media - DVD - by mail.

I have an iMAC G5 PowerPC (not Intel) running10.5.8. I sync my iphone to iTunes - but just learned I must have Snow Leopard to do so. Yet I can't install Snow Leopard as the G5 is not Intel. What do I do? How do I move music

I have an iMAC G5 PowerPC (not Intel) running10.5.8. I sync my iphone to iTunes - but just learned I must have Snow Leopard to do so for my new iPhone 5S. Yet I can't install Snow Leopard as the G5 is not Intel. What do I do? How do I move music and pics? And keep them synced up as I purchase more?

Sorry, but that is correct. You need Snow Leopard to sync your phone and the latest version of iTunes and you old G5 cannot run that.

I can't install Snow leopard on my hard disk which has 10.4.11 on and lots of space.

I can't install Snow leopard on my hard disk which has 10.4.11 on it and lots of space, I run the snow Leopard install disk and it says it cant be installed on my hard disk, which has 160 GB of space.

Which iMac? If it's a G5, the highest OS you can run is Leopard. Are you using the full retail copy of Snow, or a grey, machine specific disc from another computer? If it's the latter, that's the reason.

Can I install Snow Leopard on MacBook Pro 2013

Can I install Snow Leopard on my new MacBook Pro 2013. I'm so tired of the UGLY grey icons. I keep thinking that the mail or iPhoto window is not the active one because everything is grey. I use Snow Leopard on my 27inch iMac and love it. Nice RED delete button for mail, etc. Thanks

Firmware restrictions prevent directly loading any OSX earlier than what came with the system.
The *only* way around is to load SnowLeopard *Server* (not Client) into a virtual machine (Parallels, VMWare Fusion, VirtualBox). But that costs $20+shipping/tax for the disk and is a learning curve into SL Server. And you *still* need your host OSX to run it, and the VM will not most efficiently use the hardware resources.

Can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts.

I have the same trouble, I try installing rEFI but when I try start my Pro from DVD doesn't recognize.
Can I start from USB Memory? with files from SL DVD? or have some thing else?
I have original DVD of SL 10.6.3, if I buy the latest stable version, can I install? or the EFI firmware with Lion change again?
I try to use Lion, more than one week but I can't, and some app that I use for my profession, doesn't work, I really need downgrade to SL.
Really Thanks for any help.
