Dear Experts

 

I have got laptop Acer Aspire V3-372 with (SSD hard drive)

 

Looking to install windows 7 64-bit instead of windows 10.

 

when ever I try to install windows 7 , error message below pops up :

A required CD/DVD drive device driver is missing" Windows Installation Error

Recommended AHCI/RAID and NVMe Drivers

I am aware of that as when I checked their website I realized it is only for windows 10 no windows 7

But I am still interested to do install windows 7, but I am stuck at the point where external USB pen drive or external USB CD ROM can't pass the error message above

and cause is

In order to resolve this you need to download the appropriate RAID drivers for your computer's motherboard. If you know the manufacturer of your motherboard you can usually get these from their website or a disk that came with your motherboard or PC.

Based on the this website

I remember trying to load Win 7 on a PC that came with win 8.  To get it to work you had to go into the BIOS setup and Disable UEFI and Enable Legacy Boot.  I found these instructions which may help:

Did you disable Disable UEFI ?

 

Yes we have an option to choose either UEFI or MBR , if you choose any one it will disable the other.

You may need to "Unlock" the BIOS to get all of the options.

 

Something like this:

 

 

Click on the More button and read the instructions.

How is the Windows 7 installation going?  Did you have to go to the various chipset and device manufacturers, download their Windows 7 stuff, install said driver material?  So far, so good?
