i installed a sata controller because the sata controller on the motherboard went out. I can easily install ubuntu but when i try installing win 7 it asks for a cdrom driver, when i try booting from usb it asks for hdd driver. i have tried every solution and cant figure this out
The windows installer does not know how to talk to the SATA controller and as such, it cannot identify what drives are attached to it. Windows comes with native drivers for Intel chipset controllers and many common discrete controllers but apparently it does not come with yours. To remedy this you will need to provide the appropriate Windows 7 drivers to the Windows installer at install time. You can usually find these drivers at the manufacturer's website.
