I'm trying to install Windows 7 Professional SP1 64 bits on a NVMe SSD from a USB drive. I know Windows 7 does not have NVMe support, so I need to install the drivers during the installation. The problem is that during the installation I cannot see my USB drive were I copied the drivers. Here is what I did:
- I used the Rufus tool to create a bootable USB in GPT partition UEFI mode FAT32 format.
- I added the drivers to the USB and to a second USB.
- I inserted the USB in the computer's USB 2.0 port and entered the BIOS.
- on the BIOS I enabled CSM support and selected UEFI mode for Storage and PCIe.
- Then I booted into the installer and it asked me for a driver which I was expecting.
- I clicked on Browse and I could only see the X: drive which has the installation, but I couldn't see my USB drive.
- I inserted my second USB, but that didn't work either. I read comments of people inserting it on the USB 3.0 slot and that why it didn't recognize it, but that isn't the case here, I'm using USB 2.0.
- Mobo: ASUS Z170-A
- CPU: Core i7 6700k
- RAM: 2 ✕ 8GB DDR4 2666Hz Hyper X Fury
- SSD: Samsung 950 Pro NVMe M.2.
I might be missing something in the BIOS, but I don't know what.
