I am trying to install Windows 7 on a Lenovo Legion Y520.
It uses the Intel 100 Series C230 SATA controller.
During the install, Windows 7 produces an error that it is missing the disk drivers. However, when I select "browse" to find device drivers, I see that the existing Windows partition is already mounted. So it seems the included SATA drivers are already working.
I tried this with the "AHCI" BIOS option as well as Intel Premium RST RAID enabled.
I downloaded the Intel RST driver, and the Windows 7 Installer claims to have successfully installed the driver, but still claims that no new drives are available.
Why does Windows 7 Installer tell me that it cannot detect disks when it obviously is detecting the disk and mounting partitions on it?

At which point in the install does it pop up with the error? What's the EXACT error it's showing you? – Ƭᴇcʜιᴇ007 – 2017-04-27T18:16:30.493
Immediately after choosing "Install Now", where you would normally select a disk or partitioning options. – stands2reason – 2017-04-27T18:17:30.353
2As asked, what's the exact error message it's showing you? :) – Ƭᴇcʜιᴇ007 – 2017-04-27T19:37:31.840
if you install win7 from a USB thumb drive, use the 1 USB2 port, not the USB3 ports – magicandre1981 – 2017-04-28T15:44:04.173
