Mid 2010 iMac upgraded SSD, can't seem to install windows via bootcamp. Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems error

I have windows 8.1 on DVD & on USB CF Reader/Card. I've followed the full steps in bootcamp, but when it restarts and its time to select the bootcamp partition to install windows (after alt rebooting to the efi startup) I get the "Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems" error.
I've scoured the internet trying different solutions that seem to work for everyone else, but to no avail. I've reformatted from that screen, doesn't help. I've removed bootcamp partition and manually partitioned using disk util, leaving it empty once partition-wise, and filling it with a blank partition the second time. I've done a full back up and clean re-install of Yosemite, and nothing seems to be working.
Thats when I switched to DVD install, as I heard sometimes you can't install with a CF card. When I alt-boot, I can see EFI-windows and windows, but if I select EFI-windows, same problem as before, and if I select windows, I get the black screen of "no bootable device please insert boot disk and press any key."
I've been stuck w/o bootcamp for over 2 years now. Anyone, please help?
Mid 2010 iMac running 256gb SSD, Yosemite 10.10.1 trying to install windows 8.1

I am having the same problem. Windows is trying to install. It identifies the various partitions but says that I cannot install Windows on the Boot Camp partition or any other. I select Drive options (advanced) and Format the Boot Camp drive, but it makes no difference.
This is the Windows error:
Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.
Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer BIOS menu.
I am not sure what Csound1 is suggesting with that post above. There are some involved suggestions over here <https://discussions.apple.com/message/23548999#23548999> about using Disk Utility to delete the Boot Camp partition and create new ones - is that the idea?

"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks." Error

Hey Im getting the following error when trying to install windows from a USB.
"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks."
I installed the windows 8 (64bit) iso using boot camp to a usb. I was able to do this after changing the info.plist to allow me to place the iso on the usb. After I make the partition and start the install, I get the above error. I formatted the partition in the installation but I keep getting this error. I've repreated the entire process but i keep getting this errror and the disk utility says my partition is a Windows NT File System (NTFS) so im not sure what's going on. If you can help me that would be greatly appreciated

I found one solution to this problem on hp forum but my laptop has boot legacy and does not disable the efi boot order.
HP Model# HP 1000-1140TU Notebook PC
Serial# 5cg2481dbg
Product# c8c94pa#uuf
This is solution which is found on hp forum
SolutionThe resolution to this issue depends on the the hard disk volume size:
Follow these steps if the hard disk volume size is less than 2.19 TB:
Temporarily disable the EFI Boot Sources setting in the BIOS:
Restart the computer, and then press F10 to enter the BIOS.
Navigate to Storage > Boot Order , and then disable the EFI Boot Sources .
Select File > Save Changes > Exit .
Install the Windows operating system.
Enable the EFI Boot Sources setting in the BIOS:
Restart the computer, and then press F10 to enter the BIOS.
Navigate to Storage > Boot Order , and then enable the EFI Boot Sources .
Select File > Save Changes > Exit .
Follow these steps if the hard disk volume size is greater than 2.19 TB:
Install the HP BIOS Update UEFI utility from the HP Web site:
Click here to access the document "HP BIOS Update UEFI" .
NOTE:The HP BIOS Update UEFI utility is installed by default on some HP computers.
Follow the steps in the Microsoft document titled "How to Configure UEFI/GPT-Based Hard Drive Partitions" (in English) to create a GPT partition.

Windows cannot be installed to this disk 0. The selected disk has an MBR partition table. On EFI system, Windows can only be installed on GPT disks

Hi All,
I have been trying real hard to install Windows 8 on my Macbook Pro early 2011 model. I followed the instruction given by Bootcamp word to word, all things went very smoothly untill I was asked Windows Setup Instaled to selct the Hard drive. Here's the error:
"Windows cannot be installed to this disk 0. The selected disk has an MBR partition table. On EFI system, Windows can only be installed on GPT disks...."
Let me know guys what should I do?
Thanks,
Attiqe

You have started the Windows 8 installer in EFI mode, and you don't have to start in EFI mode on a Mac because your Mac emulates a BIOS and a MBR partition table in order to install Windows in non-EFI mode.
To start the Windows installer, hold the Option (Alt) key while your computer is starting and have a look at all the boot options you have. You should see two with a DVD above and they must be named "Windows" and "EFI Boot". Choose the option with "Windows" and follow the steps to install Windows. Note that you have to format the "BOOTCAMP" partition from the installer to be able to install Windows.
If you are trying to install Windows from a USB drive, note that your computer isn't compatible to do it

No more optical drive and windows 8 issue: "Windows cannot be installed on this disk as it has an MBR partition table."

I have an Early 2011 13" MBP going strong with an SSD and original HDD installed in the optical drive. However, having had success with windows 7 on my old HDD I was planning to install Windows 8.1 (from .iso) on my SSD. However, for the past day or so it's been a nightmare.
I tried the official procedure but by editing the bootcamp info.plist so I could boot from USB (you can't install windows from an external optical drive apparently) partitioning as bootcamp wanted too.
I then tried it a number of different ways using disk utility etc and with an empty space
However, I always seem to end up with the error "“Windows cannot be installed on this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only installed on GPT disks“
I read some interesting stuff here http://www.royhochstenbach.com/installing-windows-8-1-on-a-2013-mac-pro/
He points out that
"Windows 7 and 8 in x64 support EFI. Normally if you install Windows on a Mac and use the installation DVD, it boots into regular BIOS mode, thus can be installed on an MBR partition. I tried the same, but since the Mac Pro doesn’t have an optical drive I had to use an external drive. And apparently the Mac boots external optical drives in EFI mode too. The Bootcamp wizard is aware of this, and creates a GPT partition on a non-superdrive Mac but an MBR partition on a superdrive Mac."
This means Bootcamp is essentially making the wrong type of partition?
My real question is? How do I install it windows 8? I'm really on my last legs!
I really don't want to have to open this thing up and reinsert my optical drive as its really really difficult to get out of the enclosure (would probably have to break it).
A huge thanks in advance!

Hi,
Have you tried that suggestion?
You also could use this commands to check and install again:
Inside windows installer, hit Shift+F10 to get a command prompt, then run diskpart and type List disk to displays a list of disks and information about them, such as their size, amount of available free space, whether the disk is a basic or dynamic disk,
and whether the disk uses the master boot record (MBR) or GUID partition table (GPT) partition style.
and then select the target disk. Zap the drive (with the clean command), create GPT table (new gpt), create the GPT-EFI special partitions.
Step-by-step instructions is here for reference:
HOW TO: Use the Diskpart.efi Utility to Create a GUID Partition Table Partition on a Raw Disk in Windows
http://support.microsoft.com/kb/297800?wa=wsignin1.0
Then reboot so the firmware finds those partitions and adds the disk to the EFI-native boot order (Windows installer checks this).

I can't install Mavericks on the new SSD in my mid-2010 iMac

I recently had my old 500 GB hard drive swapped out for a new 480 GB SSD on my mid-2010 iMac. I made a flash drive into an OSX Mavericks installer per instructions from online tutorials. With the flash drive inserted, I formatted the new SSD in disk utility and then selected it to install Mavericks. However, I can't complete the installation, which is supposed to take 26 minutes, because the screen goes black midway through. I tried this twice and the second time moved the mouse periodically to make sure that the computer wasn't going to sleep. Same thing happened. Installer says that the installation can be recovered, but it will not complete installation. Any advice much appreciated!

Wondering if this can be done
Yes.
http://www.ifixit.com/Device/iMac_Intel
Also I have 4 ram slots with 2gb in two of them can I install two sticks of 4gb in the empty ones without impacting performance
Yes. Recommended in pairs. So 2x2GB + 2x4GB SO DIMMS for a total of 12 would be fine.

I want to fit a SSD to my 21.5 3.06ghz mid 2010 IMAC; Is it possible to install the current 500gb sata drive into my older 20inch A1224 IMac?

My A1224 20 inch Imac has a damaged HD, so I am wondering if the 500 gb sata drive installed in my mid 2010 imac can be installed as I am looking to upgrade to SSD and would like to make use of the 'spare' HD.
If t.his is not possible can someone recommend the best drive to by for the older mac?
Thanks

My recommendation for the older drive would be to use it to create a bootable backup, that way you would have 2 backups. Your basic Time Machine backup and a redundant (very good idea for backups!!!) bootable drive. All you need is an expensive enclosure which you can find for less than $30.

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

Hello Harrisonhcue,
I would be concerned too if I was getting the message "no hardware installed" when trying to use Wi-Fi on my MacBook Pro. For a message like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
You can find the full article here:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

Pixelation after upgrade to Yosemite - mid 2010 iMac 27in

I have a mid-2010 iMac 27in with 16GB of RAM, 2.93GHz Intel Core i7, and an ATI Radeon HD 5750 1024MB display adapter. I also have a second display attached which is a 27in LED Cinema Display. I have never had a problem with either display with any of the previous versions of OS X. I upgraded from Mavericks to Yosemite over the weekend and now have random pixelation. Usually blotches of Magenta pixels, quite large in some cases. Sometimes the color varies and may be like a lime green. It doesn't show up on an open windows, just on the desktop background and it shows up on both screens, but not necessarily at the same time.
I have reset the PRAM and the SMC but problem persists. This sounds like a possible driver issue, but just guessing. Any thoughts?

A client reported that this helped a lot:
Turn off Transparency:
To turn off the transparency:
Under the Apple menu, choose System Preferences
Choose Accessibility
Choose Display
Click the "Reduce Transparency" check box

Windows 7 blue screen on Mid 2010 iMac running 10.8

I had previously had the 64 bit version of Windows 7 Home Premium running on my mid 2010 iMac running 10.7. However, after upgrading to 10.8, my Windows installation would blue screen after booting. I suspect this was due to upgrading to 10.8 as I didn't make any changes to my Windows install because I only use it for gaming.
I've since removed the Windows partition, and tried a clean install via the Boot Camp Assistant. Windows installs just fine and boots cleanly. However, after installing the Apple Boot Camp drivers (freshly downloaded during the Boot Camp Assistant process), Windows blue screens upon booting. I can repair the Windows install using the built in process, but any attempt to install Apple's drivers results in blue screening. I've tried a clean Windows install and redownloading Apple's drivers several times with no luck.
Does anyone else have any suggestions on how to resolve this problem? Thank you for your help!

I do see this. And I suspect Windows updates. Not Apple (though I would be the first to suspect those too).
iMac graphic drivers for Windows seem touchy and common. The April Windows monthly patch updates hit a few iMac users.
One person found that if they only did updates in smaller steps and not all at once they were fine.
Tuesday this week was another Patch Tuesday.
Games, heat, disk blocks, even RAM errors - one person recently we went round and round... bad blocks not heat, new disk drive and they were 100% stable and rock solid but was hard to rule out. Windows though is easier to test RAM and sectors. And Lion was not even aware or sensitive to those bad sectors and read errors OR RAM errors that Memtest clearly showed (run in OS X).
One person had upgraded RAM, low and behold the new DIMMs were just not fully pushed in and seated and making good contacts.
Try to rule out hardware. Maybe you stumbled on bad block being used now. Run chkdsk if nothing else.
And when updating or preparing to, run Registry cleaner in CCleaner first, Go To %TEMP% and remove everything there. Make a system backup image to another disk drive (NTFS) or with WinClone 3 (HFS, $20) or CampTune ($20).
Or it could just be uninstall one driver at a time, start with GPU, look at what was last installed. Windows drivers are not desireable for GPU. Get the one from AMD or Nvidia instead.

Mid 2010 iMac Windows 7 Problem

Hey there,
I have an Mid 2010 iMac running OSX Lion and I have Windows Vista installed via Bootcamp.
I have Windows 7 saved to a USB drive, and I tried to upgrade to 7 directly from within Vista but when the installation was completing I just got a black screen. I restarted a few times, but still got the black screen during the end steps.
I've tried to start from scratch about 3 times now, but it still wont work.
Can this problem be solved?

I'm experiencing the black screen crashes since I started using Windows 7. It doesn't matter if it's 32 or 64 bit, the issue is persistent. First I thought it was the updated nVidia drivers, but after putting a fresh installation of Windows I left the original Boot Camp graphics drivers and the same black screen crashes continued.
However, when I'm running various computer games which utilize lots of GPU power, crashing never happens. Then, when I exit and start using Explorer, IE, MS Office and other simple tools, my computer goes dark. I don't believe reinstalling would change anything. This is definitely a unique problem that I just can't seem to figure out.

32GB Mid-2010 iMac

Does an Mid-2010 iMac support 32GB 8x4 of ram?
Yes, it does.
Do not get OWC ram, mainly because it is overpriced.
If you are looking to upgrade get it from NewEgg.
Corsair 8GB DDR 1333

System start freezing after installing 32 GB ram. Suddenly wait cursor doesn't stop spinning and I can't do any operation. I've got to power off holding power button. Hardware test is ok.
Searching for the word "error" in the console I found this:
