kingoffright Posted January 4, 2020 Share Posted January 4, 2020 (edited) Dear all, I have a external harddisk about 500GB, I installed the clover into it and the harddisk is GPT format, below is the 3 partitions details: FS01: EFI - disk0s1 - fat32 FS02: install mac image - disk0s2 - hfs+ FS03: install windows 10 - disk0s3 - fat32 I can use this external harddisk to install Mac without issue, I use below steps to install windows 10 enter the FS03: cd to efi/boot/ and excuete bootx64.efi after pop up the windows install screen, i click next and it shows error 'A media driver your computer needs is missing...' and the installation can not go any further. Firstly I use ultraiso to write the windows 10 image to a flash disk and no issue to start install window 10 so the image is working fine. Since I dont know how to write a wiindow installation image into harddisk partition, I used winrar extra all the files into disk0s3, am I missing some steps or actually clover not support to install windows by partitions, apprecating any helps.

Slice Posted January 5, 2020 Share Posted January 5, 2020 @kingoffright Looking to disk1. If any partition except EFI formatted as FAT32 then it will be MBR partitioning disk on which UEFI installation is impossible. So format fs03 (disk1s3) to be NTFS. Clean MBR table for this disk to be GPT and not Hybrid. Take Windows installation ISO, mount it in any program and just copy its contents to fs03. It is enough, the image does not contain invisible files. Link to comment Share on other sites More sharing options...
kingoffright Posted January 5, 2020 Author Share Posted January 5, 2020 (edited) @Slice Thanks a lot for your advise but I extra the installation media files to NTFS format still no luck for me, i try win7_2008 today and still same error, below is my harddisk details: After system boot up into Clover, I enter FS2 and manually boot into windows installer: its chinese so I find a english version below: I click browse and below are the drivers it detects: compare to the files I extra to WIN7_08R2(F:) partition, the sources folder in BOOT(X:) seems contain less files: Edited January 5, 2020 by kingoffright Link to comment Share on other sites More sharing options...
Slice Posted January 5, 2020 Share Posted January 5, 2020 It said that the installation can't see your external drive because a driver absent. What is your external drive? USB? TB? FireWire? What driver is absent? Link to comment Share on other sites More sharing options...

kingoffright Posted January 8, 2020 Author Share Posted January 8, 2020 (edited) The issued been resolved, I use third party tool - Paragon Disk Mange to create the external HD for installation media, somehow Windows can not detect it, since I need a GPT format, so I create the partitions in Mac then I can skip the error that missing installation media, but another issue come out: 'windows can not install in GPT', 'no more space for windows to crate partitions', after couples of days testing I'm tired of using windows installer, since my installation image is 'ready-made', I enter the PE and use winntsetup to install the windows, very easy and no noising errors. But the installation order is very critical: 1. Install Mac, use mac to create the GPT and EFI, leave enough space for windows partitions.(Diskutil resizevolume macos 50G) 2. After Mac first reboot, boot into windows PE and install windows, use windows native diskpart command to create partitions, the current EFI should still empty(create part primary size=50000) 3. Still use external Clover to boot into windows to complete the installation 4. After Window complete, back to continue the Mac installation 5. Finally enter the Mac system, use Clover installer and install the Clover in EFI then no need the external Clover USB any more, thanks for the people was helping me.
