Setup was unable to create a new system partition....

My system specs are updated. The issue is the asus utility needs the Win7 install DVD which is not SP1 and I'm trying to use a .ISO file that is a SP1 installer.

Yeah, it's either DVD to USB or DVD to ISO. I already downloaded a SP1 ISO. Again, my issue is the NVMe drivers. My keyboard and mouse work fine during installation, so the USB 3.0 drivers aren't as important as they're being made out to be... for me at least. Relating the the OP, the problem I have is Win7 will not see my Samsung 960 EVO SSD without the drivers being installed. So I'm attempting (not succeeding) to make an installer with the drivers included so I can work around having to install it to a SATA HDD, then clone that disk to the SSD so I can use the SSD as my OS drive.

I wish he posted how he got around the issue. I'm not having a problem with my BIOS detecting the drive, just the Win7 installer. Maybe the SP1 installer will detect it???

Are you installing with service pack included on DVD normally it should see the SSD drive or you can give it drivers during installation. Windows writes a signature to the disk so if you clone and leave both drives in it sees they both have same signature. Swap ports so c is disk 0

I missed this part. Would the SP1 detect my SSD? If not, how would I "give it the drivers during installation"?

Did you try the Asus App?
Attached are the needed drivers to insert into the Win 7 installation disk

Yeah, it's either DVD to USB or DVD to ISO. Nice, you have the NVMe drivers... perfect. I'm going to attempt to make this happen! Thanks for all the help, will keep updating as I go.

- First of all, you must set BIOS to be able to run Win 7. On BIOS, disable fast boot, secure boot and enable CSM (Compatible System Mode). Under CSM, set boot disk priority to UEFI and disable net boot.
- At least you must insert the USB 3 drivers into Win 7 installation disk so during installation you can load the SATA and nvme drivers.
- The easiest way to add the drivers into Win 7 installation disk is to use the Asus app. http://dlcdnet.asus.com/pub/ASUS/mis...852.1488762401
- If the Asus app ask to insert a Win 7 SP1 DVD and you didn't burn one, use Magic disk. It will create a virtual CD/DVD drive. Load the Win 7 SP1 iso on it and then point the Asus App to it. Mount ISO Files - Freeware MagicDisc Download
- If the Asus app doesn't add the SATA and nvme drivers into the Win 7 installation disk, you can add them during installation. You will have to copy the SATA and nvme drivers to another USB flash disk.
You must boot the Win 7 installation disk (with, at least, the USB3 drivers added) as UEFI.
