Windows is installed on pure GPT but windows boot files are located on the MBR drive. Thanks to milindsmart we have others solutions to boot windows installed on pure GPT. If you have questions, I would be happy to answer if I can.Įxtra Guide (mainly for chameleon users or people who can't make Clover to work on their computer) This guide is still in BETA and not complete so no complain Then configure Clover to allow booting from legacy OSīoot your computer and select your OS X partition in CloverīIOS -> CLOVER EFI -> Windows Boot Manager (UEFI)īIOS -> CLOVER EFI -> OS X (Apple EFI emulate by Clover)īIOS -> CLOVER EFI -> Chameleon -> OS X (Apple EFI emulate by Chamelon) Use fdisk if you are not sure : install the PBR and chameleon only. Install Chameleon on the OS X partition WITHOUT erasing the main boot sector Now you can boot Windows without key, just with selecting Microsoft EFI in Clover Menuįor the people who use Clover to install OS X you can boot OS X too. You must change the clover installation options to install the boot sectors. That's all : you have a working install of windows with pure GPT and BIOSīut you still need to use your clover key each time you want to boot.ĩ - Install OS X using Clover or Chamelonġ0 - In OS X mount EFI part and install clover on it WITHOUT formatting the EFI part. Then select Microsoft EFI from the Clover menu. G: is the windows partition and H: the EFI partition of your diskįor these steps you will need to install the windows ADK.Ĩ - remove your windows install media and reboot to clover usb. Imagex.exe /apply F:\sources\install.wim 1 G:\į: is the mounted iso and G: the windows partition. See 7bisħbis - From a windows OS (I used my Windows To GO key) : use the the imagex command to expand a windows ISO on your Windows partition It worked with DUET so maybe it can work with Clover. ! It doesn't work for me ! The install failed. Install windows on the partition you've made previously. Clover didn't see the windows DVD for me, but it may work for some people.ħ - Boot from the Clover USB and select your windows install media. There are a lot of tuto explaining this.Ħ- Prepare an windows install usb install media. Keep enough space at the end of the disk for OS X and/or Linux.ĥ- Prepare a Clover EFI boot key. I will complete this tuto with more informations and screen later because I don't have a lot of time (Baccalauréat is coming for me.) but you can follow this short guide :ġ - Partition your hard drive with GPT ! you will lose your data ! You can use the program you wantĢ- Create EFI partition : I used a Diskpart on a windows to go key to make sure windows detect the part is an EFI oneģ - Create an MSR partition using diskpart (windows)Ĥ - Create the root file system (NTFS) of your windows install. I just have to move Clover from the USB to the EFI part of my GPT disk and install OS X (I received it two days ago) I'm booting from an USB key with Clover installed on it. multi OS setup between EFI and legacy OSĪt this time, I do all my tests on a ThinkPad T410 with a BIOS and Windows 8.1 and I have a clean Windows install on GPT. In the hackintosh world we have the best : Clover EFI bootloader.Ĭlover EFI is a fork of DUET which emulate Apple EFI on PC to boot OS X, but it can emulate UEFI too. Tianocore/DUET is often used in all the tutoral I've seen but it's a little long to install and it won't work on all computer, according to Rod Smith ( ). But this partition scheme is very dirty : you can read this article from Rod Smith which will convince you to not use it.Īn other solution is to use the standard GPT (which is part of uefi specs) and emulate the UEFI bootloader. Many peoples bypass this by creating an hybrid partition scheme GPT/MBR which consists of using GPT partition scheme with an MBR boot sector to start the windows bootloader. But if your computer doesn't have UEFI (BIOS only), some Windows editions like Windows 8/8.1 will refuse to install on GPT : because of Microsoft policy, only UEFI computer can use GPT as system drive.ĮDIT : Before following this tutotrial, try a standard install ! This worked for Hervé. The best way is therefore to use GPT partition scheme. GPT is used on all the Intel Mac by default and if you want to use MBR for your OS X install you'll have to patch your install. GPT has many more advantage than MBR, but I won't describe them here. As everybody knows, there are two majors partition scheme on PC : MBR and GPT.
