"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.

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.

I'm trying to install OS 10.6 onto my Macbook, which currently has OS 10.5.8. I clicked install (on the DVD) and selected my Macintosh HD drive. I was given the message that that disk cannot be used because it does not have the GUID partition????

I'm trying to install OS 10.6 onto my Macbook, which currently has OS 10.5.8. I clicked install (on the DVD) and selected my Macintosh HD drive. I was given the message that that disk cannot be used because it does not have the GUID partition. In order to have a GUID partition, it suggested I go to disk utility and make the change. I couldn't see the partition tabs in the disk utility application. So how do I accomplish the GUID partition?

The problem is, reformatting the partition may require you erase the hard drive. Normally Intel Macs are preformatted GUID. The fact that yours is not, says someone who initially installed the system on your Mac did you a disservice. Regardless, you should backup your data before you upgrade. GUID formatted drives generally are not compatible with iBooks (pre-2006 consumer notebooks by Apple) Powerbooks, and PowerMacs, and iMac G5s. So if you indeed have machine with the MacBook name on the screen frame, it was not properly formatted from the beginning.

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

Im getting error message when i try to install os5.1, any help?

I have got an update msg for OS 5.1 however when i try to install it, an error msg comes up with 2 option: either close or settings as a result of not being able to install the upgrade, im not able to purchase certain apps as the new 5.1 OS is needed. Any advice on how to install this upgrade please

This happened to me too. But what I tried to do is reset my iDevice's settings, not turning my iDevice to factory mode, just go to Settings, General, Reset, Reset Settings. There, you will only reset your iDevice without losing your contents but it's a pain in the butt thatyou have to set up with iCloud and wait for about 3 to 5 hours until the process is complete, well it depends on how much data you have on your iDevice. Hope this'll help you solve the problem.

I keep getting old settings when I try to install Firefox again. I have deleted the program files and the profile, but the program is finding the old bookmarks and settings somewhere. How do I delete this information to make a clean installation?

I have a corrupted bookmark file and want to totally delete any information on the bookmarks and settings. I have deleted any files which reference Mozilla and Firefox from my hard drive and have gone into the Registry and deleted all references to Firefox. But every time I reinstall Firefox the program finds this information. Is it in the sync folder and how do I clear out that folder?

Help Can't Install Maverick "disk doesn't use the GUID Partition-"

I have an imac and i'm using bootcamp fro windows 8. so I have Macintosh HD and BOOTCAMP Partitions. both partition have Master Boot Record as the Partition Scheme. When trying to install OS X Mavericks it rell me that "This disk doesn't use the GUID Partition Table scheme. ..." it tells me to use Disk Utility to select the disk ->partition -> select Volume Scheme and then Options... but option is grayed out... I can not change it and so can not install Mavericks... how do I solve the this issue without losing any data in mac and in windows? without deleting partitions if possible?
thanks

GUID is a drive map layout. You can only change it by opening Disk Utility, highlighting the physical drive and choosing the Partition tab. Then change the partition layout to anything other than Current. The Options button below that will then be active and you can then finally change the drive map from whatever it is now to GUID.
Note that since you must repartition the drive, you WILL lose everything on all partitions. So you MUST back up everything FIRST to another drive. This can be a clone to another physical drive, internal or external. When you clone it back after repartitioning, the drive map does not change.
To check your current drive layout, open Disk Utility and click on the physical drive you want to install Mavericks on. Example:
Then look at the lower right of Disk Utility's box. If you see anything other than GUID Partition Table, as shown below, then you must repartition the drive.
The other main problem is that you have to have another drive to boot to before you can change the one that needs to be repartitioned. Clone your current drive to another physical drive, not another partition on the same drive. Once the clone is complete, boot to that drive and you'll be able to repartition the drive you need to change.

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.
