Install windows 7/8 on gpt-partition style???

can't install windows on my iMac mid 2010 with a 3tb seagate with gpt-partition style. Please Help! :S

All Macs use the GUID partition table. If you're trying to install Windows with EFI install, you should know that you can only do this with Windows 8 and Apple doesn't support this kind of installation, so it can fail and damage the Mac. The best way is to use Apple Boot Camp

Windows Server 2008 r2 install error gpt partition style

Good morning I am trying to install Window Server 2008 r2 (trail) on my Dell inspiron 15 and also keep Windows 8 when I set up a partition of 50G and go thru the install it tells me The selected Disk is of the GPT partition style. How do I fix this
issue.
Thanks

Hi,
Since we are still discussing the same problem, so I merged them.
I want to confirm some information. Is your computer boot in BIOS mode or UEFI mode? Open computer management->Disk management->Properties->Volumes.
Is your current partition type GPT or MBR?
For now,
starting with Windows Server 2003 Service Pack 1, all versions of Windows Server can use GPT partitioned disks for data. Booting is only supported for 64-bit editions
on Itanium-based systems. For windows 7, windows VISTA and window server 2008, Booting is only supported for 64-bit editions on UEFI-based systems.
So, the solution is either to change the boot mode or convert your disk. Remind, if you want to convert your disk, data on it should be cleared.
Hope this helps.

Is it possible to install Windows 7/8 from a partition on a separate drive?

Hi everyone,
Early 2008 Mac Pro with 10.8.2.
I have two sata drives mounted in my tower--the OS drive and a media drive.
I'm wondering if it's possible to partition 10 or so GB off of that secondary media drive (OS Extended Journaled, GUID), load the win 7 (or 8) ISO and install Windows through bootcamp via that new partition.
Alternately, I have an external USB drive (sata), and could possibly try that same method of formatting off 10 gigs and loading the ISO in a similar manner if bootcamp only checks between DVD media and USB for where it wants to read the installer file.
This method would circumvent the need for a blank DVD or a USB flash drive--both of which I don't currently have.
Does anybody have any experience with this?

I am trying to install Windows Server 2008 R2 Ent edition onto system that has an ASUS M3A78 Pro motherboard with 8GB of memory & an AMD Phenom II x3 2.6GHz Socket AM3 Processor
(X3 710).
I realize that this system doesn't support UEFI but I have an Adaptec 3805 RAID controller in this system that does support the advanced format hard drives, so I would think I should
be OK there.
Attached to the RAID controller are 3 - 1.5TB SATA Hard Drives in a RAID 5 yeilding 2.72TB's of usable space.
I followed the following process to convert the array to GPT.
I booted to the Server 2008 R2 Ent installation DVD.
I select next at the language \ time & currency format \ Keyboard selection screen.
Then I select the 'repair your computer' option at the following screen.
I do not select the 'repair' (default) option, but instead select the radio button above it (I forget what that's labeled) working from memory here - which gives me the option to
launch a command prompt.
I launch diskaprt from that command prompt.
First I selected the disk
list disk (this displays the installed disks)
select disk 0
The I converted the disk to gpt
convert gpt
Then I created 200 MB EFI partition:
create partition
efi size=200
Then I created MSR
partition:
create partition
msr size=128
Then I created primary
partition:
create partition
primary
...and it took remaining
available space to itself.
I assigned drive
letter C to this new first "primary" partition
Assign letter=c
I confirmed the order is:
I confirmed the partition order is:
ESP > MSR > DATA Partition
After all of that I restart into the Windows installation and attempt to install by selecting the newly created primary partition and am presented with an error that states:
“Windows cannot be installed to Disk 0 Partition 3. (Show details)”
and the details show:
"Windows cannot be installed to this disk. The selected disk is of the gpt partition style."
Any help anyone could provide would be greatly appreciated.

Is It Possible to Install Windows 7 on a GUID Partition Table Disk?

Is it possible to install Windows 7 on a GPT disk?
I created a RAID 0 array on my dual Xeon 5580 system and tried installing Windows 7 Ultimate 64-bit RTM. When I got to the "Where do you want to install Windows" part I used shift-F10 to open up a command window, then I used diskpart to create a GPT with the following partitions:
Disk 0 Part 1 - 102 MB EFI System
Disk 0 Part 2 - 128 MB MSR
Disk 0 Part 3 - 500 MB Primary
Disk 0 Part 4 - 7446 GB Primary
But there was a message "Windows cannot be installed to Disk 0 Partition 3 (show details)" - clicking on "show details" gave me "Windows cannot be installed to this disk. The selected disk is of the GPT partition style."
What gives? I thought Windows Vista and beyond supported GPT.
The problem with MBR is that you can't have a file system larger than 2 TB.
Cheers, Eric

The selected disk is of the GPT partition style - MBP 2013

Hi,
I get this error dialog in the windows 8.1 installer, when newly installing windows into a bootcamp created partition.
Machine:
* 2013 Macbook pro with retina display.
* 16GB RAM
* 1TB SSD
Reproduction:
* Use Bootcamp Assistant to create a USB stick with the Win8.1 Enterprise ISO, and the "Windows support files" (check the box in bootcamp assistant).
* Bootcamp restarts the laptop into the Windows 8.1 installer
* In the win 8.1 installer, On the Partitions screen I see 4 options
     * Partition 1 (EFI)
     * Partition 2 (OSX 600GB)
     * Partition 3 (small - likely the recovery partition)
     * Partition 4 (BOOTCAMP 120GB)
* Selecting Partition 4, gives the warning message "Windows can't be installed in drive 0 partition 4 (show details)" and the detail gives the error message "The selected disk is of the GPT partition style". The next button is disabled.
Does anyone know how to get past this?
Cheers!

hello, i was able to fix this on a intel I5 iMac as follows
- use Disk Utility
- click on the partition tab
- select the partition that was created by bootcamp, in my case it was named untitled but I could tell by the size that is was the one created by bootcamp
- delete this partition by clicking on the minus key
- create a new partition by clicking on the plus key
- give it a name and specify format as exFAT
- restart the computer and hold down the option key until you see the startup options
- select the device that contains your windows install iso image either USB or DVD drive
- win install will ask you to select the partition to install to
- select the partition you created with Disk Utility
- installer will complain that the partition format needs to be NTFS
- click on the Format button and the partition will be formatted as NTFS
- continue with the install

I have recently installed windows XP on my bootcamp partition. I am in need for the drivers and what not so that it will run effectivly and the bootcamp assistant canot find the "Windows Support Sofware" Can anyone help me find it manually?

As the title has stated, I have recently installed Windows XP on my Bootcamp Partition. I am in need of the "Windows Support Software". I am assumeing that is the information that has the Drivers and what not that allow me o properly use my Mac with windows. If anyone can help me locate this inforamtion i would be greatly.... Greatfull.
P.S. The bootcamp assistant is telling me that the Windows Support Sofware canot be found.

You both would have had correct awnsers, but i have a Macbook that is close to three years old. And i can't seem to find my Disc. The only reason i haven't ordered a new one in case of emergencies is I plan on upgrading to the new OS in less then a month.
I think the following may help me (In case anyone els is looking):

Install Windows XP in its own partition?

Hello, all! I have questions on partitioning for Windows XP Home.
I just recently purchased an Athlon 64 & MSI Neo motherboard, and I'll be getting a Maxtor 60GB Serial ATA hard drive soon. I'm looking for more speed in XP, so a coworker suggested I put Windows XP on its own partition, and data on the other.
My questions are:
1) How much space should I allow for XP's partition? After installation, will that many files be added to the partition over time?
2) What are the advantages/disadvantages of giving XP its own partition?
3) When installing data to the second partition, should I allow a Program Files folder to be created, or just install the applications' folders straight to the root of the partition?
Is installing Windows XP in its own partition the "thing to do"? Any information is appreciated. Thanks!

im not convinsed it makes any difference really
this time i never bothered my array is my c drive all 149gb of it
and i see no difference
if you dont have another drive to back stuff up on then do it for sure
then you can format c but not loose the mp3 collection
but most cases a game loaded in another partition does not work right any way after c is reloaded and needs installing again any way

I used bootcamp assistant to partition my hard drive to install windows. When I got to the part to install windows, I selected the bootcamp partition and then choose format as instructed but it would not continue stating that the partition was in GPT par

Please help!! I partitioned my macbook pro hard drive in bootcamp so that I could install windows. Everything appeared fine until I got to the install part. I selected the BOOTCAMP partition and then selected format as instucted. That was it. The install could not proceed because it says the partion is in the GPT format instead of NTSF. At this point it erased the "BOOTCAMP" name from the partion but the partion still exists.
I tried to reform by going back on the OS side, in disk utitly, erase and format. It will not allow me to select NSTF format.
What do I do to fix this??
Thanks for you comments.
Kristina

In Boot Camp Assistant when you select the format option the Boot Camp partition it automatically formats the Boot Camp partition as NTFS since this is what Windows requires. There is no option to select NTFS or any other format type.

Install windows 8.1 on gpt on a bios system

Is it possible to install windows 8.1 on a gpt formatted partition on a BIOS or non-EFI system? Where can I locate descriptions for that?

Hi,
Please know that Windows 8.1 can use GPT partitioned disks for data. Booting is only supported for 64-bit editions on UEFI-based systems.
So, the answer of your question is No.
Know more information about GPT, you can refer to following link:
Windows and GPT FAQ

Can't install Windows 7 on Boot Camp partition

I ran the Boot Camp application and it formatted a partition but when I try to install Windows 7 Home Premium full version it says the partition is invalid. There was no option to choose NTFS or FAT and now the installer is telling me that the partition is not NTFS.
What should I do?

Yup. Windows will not install when there are other drives present that have GPT.
Very old simple to just remove until later.
If you were installing to the same drive as OS X (prefer not to of course) still need to pull the drives temporarily until after Windows is done.
you do not need a new drive. You can just format the drive now that you were going to use:
Disk Utility: Partition: 1 or more, does not matter: Advanced: Options - choose MBR Windows partition table format. Click Apply. Then Apply again.
When in Windows 7, choose the entire drive - Advanced Options and delete what DU created! let Windows do its thing - no need to create or format if you deleted / removed those partitions.

No Booting of Windows 8.1 After GPT Partition Resizing with Easeus Partition Master 3.0

Hi there,
I have a Sony Notebook SVS13A3Z9ES with preinstalled Windows 8 which I updated to Windows 8.1. The notebook has a
250GB SSD which had the following GPT partitions
Partition 1: SONYSYS - 260MB (Sony Vaio tools, type OEM)
Partition 2: Windows RE - 1,4 GB (Type OEM)
Partition 3: EFI System Partition - 260 MB (type System)
Partition 4: MSR 128 MB (type reserved)
Partition 5: About 240 GB - (incl. Windows, Type Prime)
Partition 6: Windows Recovery 350 MB (type OEM)
Partition 7: Recovery: 28 GB - OEM -> I created instead a Recovery USB stick and have now another prime partition
I then shrinked the Windows partition to 101GB with the Easeus Partition Master 3.0 to create another partition dedicated for data only. I didn't use the Windows built-in partition tool because I still wanted to shift the part.6,
being able to only extend part.7 for the final data partition. After I activated the shrinking via the Easeus I had to restart the notebook. I immediately came obviously to the Windows RE environment :
- asking me for selecting language
- afterwards I was brought to the Option Menue
* Continue Booting -> led me back to the language selection
* Turn-of PC and
* Trouble Shooting ->
Proceeding with Troubleshooting
* Recovery and Maintenance -> tried to start VAIO Care but couldn't access it -> back to Option Menu
* Refresh PC -> led to the message
“The drive where Windows is installed is locked. Unlock the drive and try again.”
It seems that the C: drive was locked after shrinkingthe partition with Easeus.
* Advanced Options ->
Proceeding with Advanced Options:
* Automatic Repair -> couldn't be executed, log file on C:. With cmd the C:\> drive can be initialized but Windows folder is not found (probably locked or hidden)
* Recovery Point Recovery -> no recovery points were detected -> back to Troubleshooting
* System Image Recovery -> no image points were detected -> back to Troubleshooting
* UEFI Firmware Settings -> led to the Vaio Care RescueMode screen which can be seen here
http://community.sony.com/t5/VAIO-Upgrade-Backup-Recovery/How-can-I-enter-bios-on-my-vaio-I-want-to-boot-from-the-cd-drive/td-p/60063
e.g. starting Windows from there led to WinRE again
* cmd window ->
Finally we have the cmd Window. Here are several postings in the internet with potential solutions but no one helped me so far. Example postings:

http://pcsupport.about.com/od/fixtheproblem/ht/rebuild-bcd-store-windows.htm
http://www.winhelp.us/repair-your-computer-in-windows-8.html
I tried so far:
- chkdsk -> executed, no problems
- Bootrec /fixmbr -> executed
- Bootrec /fixboot -> executed
- Bootrec /rebuildbcd, result:
Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.
Restart brought me directly to language selection and Windows RE back again.
BCDBoot c:\Windows -> executed successfully but restart
back to WinRE
Then I assigned a letter to the EFI partition using diskpart v6.2.9200 and replaced bcd file with
1. method: BCDBoot c:\Windows /s z: /f ALL (z: letter of EFI partition) ->
executed successfully but restart back to WinRE
2. method: Bootrec /rebuildbcd -> executed successfully but restart back to WinRE
I had the recovery USB stick inserted but it was never used so far.
Do you still have other solution ideas restore the booting or an approach how to unlock the GPT c: drive with Windows again ? I would appreciate that very much.

Hi，
According to your description,the system was damaged by the partition tool.
Since you upgraded to Windows 8.1,you cannot use Windows 8 recovery media to repair the system.
If you have some important data in the SSD,I suggest that you move the ssd to other computer,and backup the data.
As you said,you had the recovery USB stick inserted but it was never used so far.
For this issue,please change your BOIS setting for USB.
I suggest you use your recovery USB stick to reinstall your system.

Installing Windows 8.1 with bootcamp, partition issues.

So I am trying to install windows 8.1 onto my MBP running the latest 10.9.2 operating system. It took a while to get the HD to successfully partition, however when I finally got it working, upon booting from the USB drive I got this error message
windows cannot be installed to this disk. the selected disk has an mbr partition table windows can only be installed to GPT disks
Is there any way to change the partition table or to fix this?
I just tried restoring the partition to one, verifiying and repairing the disk in recovery mode, then re-running boot camp, issue persists.
running late 2011 15" MBP

Well, when you start the computer you should press ALT to show the boot manager. With Windows 8 and 8.1 (for Windows 7 there's not this problem) there should be three different icons: the OS X one, and then two called Wininstall (or something like that) and the other is similar but there should be written something like "EFI Boot".
Well, don't choose the EFI Boot one and you should be fine.
If you choose the first one the Windows installer format the Bootcamp partition correctly, and then you can start the procedure.

Failed to Install Windows 7 : Drive is GPT type

I'm having a hard time installing Windows 7 Ultimate on my Mac. It may be a compatibility issue. I've had a look over some posts but I'm looking for an informed confirmation.
I have an upgraded late 2007 iMac (7,1). I've upgraded the HDD to a 3TB drive. Using Boot Camp Assistant, I've partitioned the HDD to 57GB for the windows installation. Then using a windows installation disk, I've tried to install windows 7. The start up runs fine, and it recognizes to BootCamp Partition. But when I try and format it to NTFS (which according to Disk Utility it already is), I get an error stating that windows cannot install on what appears to be a GPT drive. Hmmm, is there something I'm missing. I've using Bootcamp 4.0.3 Do I need to roll back (if that's possible) to an earlier version of Bootcamp Assistant and use Windows XP. I don't need 7.
Any assistance would be appreciated.
TIA

A. There are problems with 3TB drives
B. Is there another drive present in your iMac
C. My best gueess: you would have had to reduce the 3TB down to under 2.2TB first, and leave 800GB as free, and then set aside a partition for Windows

Installing Windows 7 on a current partition in drive bay 3

Hi,
I want to install Windows 7 on my 2011 Macpro. I currently have a 300GB partition I'm not using in drive slot 3 of the computer..
When I open bootcamp to prepare the drive, It tells me I cant do anything with this drive apart from format it and then partition.. Is this necessary given the partition is already there, or can I just use it? If so, do I just need to format it to FAT32, then start the windows 7 installation process outside bootcamp?
Also, it says in the apple bootcamp guide that for Windows 7 to install, the drive with its partition on needs to be in drive slot 1.. Is this true or is it fine where it is?
Finally, it it won't work installing on the about partition, I have a spare 250gb SATA I drive (from an old G5 Powermac).. Can I put this in drive slot 4, format it and install windows on thet? Would it still need to be done through boot camp?
Sorry for all the questions, and thank you in advance,
Tom

Boot Camp Assistant is limited not very forgiving.
Any drive bay is fine, I use #3 but some find #1 or 2 work better.
Remove all the other drives when you do install.
Formatting and having one drive dedicated is much easier. That way you don't even need Boot Camp Assistant other than to download drivers (you aren't on Lion so no).
BCA prepares the partition table. It expects to have GPT and make the protective MBR active and support booting Windows. That is its only real purpose. And is most often used where Mac OS is present on partition.
The partition you had isn't prepared for Windows. You would hve to turn it into an OS X volume only, small perhaps, then use the rest.
Pull your drives and use the 250GB. But do so with just that drive. If you can't then move it.
there is no such thing as a 2011 Mac Pro workstation, although lately they not only ship with Lion (makng it 2011) but the firmware will no longer support downgrading to 10.6.8, that would be "2011."
If you have and want to really support two cpu sockets, then Pro version. And of course 64-bit. So Windows 7 64-bit SP1 System Builder $129 from 'Egg or Amazon if you still need to buy something, or an MSDN account of course.
