Downgrade Windows 10 to Windows 7 Professional IdeaCentre 300S-22ISH

2016-04-25, 13:12 PM

I have an IdeaCentre 300S-22ISH with Preload Windows 10 Home edition. I tried to install Windows 7 Professional 64-bit into my 1TB SATA Hard Disk without deleting the Lenovo SATA Hard Disk since I have a spare HDD.

 

However, when the Windows 7 Professional installation wizard started, there is an error prompted to Load Driver

 

"A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.  

 

Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step."

 

Does anyone has encountered this message during installation the Windows 7 Professional and what is the best solution to resolve this. Appreciate if any genius could advice to help.

 

Thanks

Solved! See the solution

Issue has being resolved. Manage to change the setting of the BIOS on USB and load Windows 7 installation via the Windows 7 CD and it resolved the issue. As this model is the 6th Gen Intel chipset, there is no default USB2.0 & 3.0, I will have to manually search for the driver to get it loaded and function. 

 

All drivers is loaded without any hassle and is in great conditions.
