I'm hoping to get some help here. I'm pulling my hair out over this issue.
I cannot get Win7 to install onto a hard drive in EFI mode. I get this error. I can install Win7 in MBR mode just fine (disable secure boot, enable CSM -> legacy only, ensure install media is also formatted MBR -> get to install screen and go from there). I want to do it in EFI mode instead though. I've used the X399 USB patcher to no avail, same issue. I know the USB install media I have can install EFI mode fine because I've installed Win7 with it to an Intel Z77 motherboard (Note: While I can install it in EFI mode, I must have motherboard settings set to UEFI only, secure boot off, and windows 8 features turned off). Only then will it pick up the USB fine and install away. I confirmed it installed in EFI mode by opening diskmgmt.msc and verifying the volume has an EFI partition and is formatted GPT style. Here's what I've done so far Disable Secure boot. Enable CSM and do varyign combinations of Legacy only and UEFI only Disable CSM Disable IOMMU Changed PCI-E gen speed from auto to gen2 I've also messed with the USB stick itself: I tried making bootable install media with rufus, formatting as GPT FAT32 and GPT NTFS to no avail. I think I tried MBR FAT32 and MBR NTFS but those wouldn't work anyways due to the need for EFI booting to be on GPT formatted media. I've also used a hard drive as installation media to bypass USB driver issue (connect SSD to a USB adapter -> use rufus to make install media onto external hard drive, pointing to win7 iso file to make bootable disk. I've tries MBR and GPT for UEFI options, both work in Z77 intel machine but not on AMD x399 machine) and no beans with that. Anyone have any idea? Step by step fix?

ssateneth, W10 version 1703 and higher are the only officially supported versions of Windows for AMD X399. If you would like to pursue this, then PM parsec. He has some insight into UEFI and W7. Enjoy, John.

That's weird, because both AMD and Asrock supply drivers and apps for Win7 + X399.

I agree, ssateneth, and I do not understand why. Enjoy, John.

Hi,
I am having the same issue. I am currently using an X399 Taichi Mother Board with a single Samsung Evo 960 M.2. I have been able to build easily with Windows 10 Pro latest edition. I have been trying quite hard for the last few days to build it with Win 7 and cannot get past the load driver screen. At one point I got the load driver page using the Floppy Disc Image and for some reason the driver would not install. I am not sure the DigiCert verification at this point. Would appreciate if some one could help clarify the correct set of drivers for Windows 7 for the controllers. thanks and best regards, K

technikar, I do not understand what you have or what you are trying to install. Please post all your system specifications as I have in my signature. What Floppy Disc Image are you talking about? The only floppy image I am aware of is for RAID. Please look here: https://support.amd.com/en-us/download
and go through the selection for chip set drivers. You will find that AMD offers NO chip set drivers for W7, only W10 x64. So even if you can get running you will not be able to update to the latest drivers. BTW, parsec seems to be here no more. Good luck and enjoy, John. |
