Reinstalling win 7, can't put in the driver cd

Put the SATA/Rapid Storage driver on a flash drive and connect it to a USB port:

@Maxims  Did this Win7 reinstallation CD actually come with this particular system?  The reason I ask is that the error you're seeing at the point that you're seeing it can occur if the Windows Setup environment itself doesn't have the right drivers for the system's hardware, and you're not supposed to pop out the CD at that point anyway.  The Rapid Storage driver workaround might work, but if not, assuming that system was designed for Windows 7 at all, one option you could consider would be to download it straight from Microsoft and creating either a disc or a bootable flash drive.  The Microsoft version would at least include SP1 integrated, which your disc may or may not.

But either way, if you're adamant about sticking with Windows 7 even at this point that it's no longer receiving security updates, at the very least make your reinstallation life a bit easier by manually downloading these specific updates beforehand somewhere else and installing them on your rebuilt PC before you start in on Windows Update.  The reason is that the Windows Update catalog for Win7 is so huge now that Windows Update can hang for literally hours before it even figures out what it needs to download (Microsoft issued a patch for that), and even if you get past that, you'd have literally hundreds of updates to download and install across multiple reboots.  But you can cut a LOT of that out with a few key updates below, which you should be able to find these updates by Googling their name or KB number:

- Windows 7 Service Pack 1 (unless you'll be using install media that has it integrated)

- KB3020369: April 2015 Servicing Stack Update (required to install subsequent updates)

- KB3125574: Windows 7 Convenience Update (takes you from SP1's February 2011 state all the way to April 2016 in one big package rather than hundreds of individual updates, but this package is NOT offered through regular Windows Update. You have to download it manually.)

- KB3172605: July 2016 Update Rollup (includes the fix for very long Windows Update scan times, so after installing this, you may still have a few dozen updates, but at least you won't be waiting potentially hours for them to even start downloading).

@jphughan, yes, both CDs came with the laptop

I think I forgot an important thing to mention. The laptop is 12 years old, but it has great characteristics

Sorry, I'm not English; moreover, I'm not into computers, so I didn't fully understand what you have said. I do this reinstallation with a guy, who is in computers, but he doesn't know English. But I'll try, what you have suggested, I just need some time make sense of it

@ejn63

I'm gonna take a look. 

But if I have it understood rightly, you suggest to put the drivers on a USB. 

We've tried it, but the computer doesn't see the USB (I men, it needs a driver to identify the USB) 

Use the USB 2.0 ports on the right side - they should be readable by the installer.  If not, you will likely need to slip in the AHCI drivers and prepare a new Windows install media set.

That said, jphugan is correct - Windows 7 is now unsupported security wise (and has been since January, 2020) -- you'd be better off installing Windows 10.  The license key on the label in the battery  compartment entitles you to a free upgrade to Windows 10.

For the media panel, try installing the 7  drivers in compatibility mode after you have 10 installed.  They may work - or it may be something you can't get working under 10.

@ejn63 yeah, thanks, I'll try it another time

The reason I want to install win7 with the original drivers, is that my computer says, there are 2 unreadable devices, and the media panel doesn't work (we think it is one of these devices). So the man who helps me, suggested to install 7,so maybe the devices will work. And after that we'll upgrade to 10 (or even split the hard drive and make two OSs) 

@ejn63 I tried it with my USB stick and a USB memory drive. It didn't work. I don't know what to do. I'll try what you've suggested with the preinstalling of all the stuff. But really, it says "if you have an installation cd in, you can take it out in order to put the driver cd in". But I physically can't take it out.
