It may have been shipped with Windows 8.1 pre-installed. Was Windows 7 pre-installed on your computer, or are you trying to "downgrade" from Windows 10?
> Are there BIOS settings that need to be changed to continue loading the WIndows 7 operating system? Yes, if your computer still has a floppy/stiffy disk-drive, and the files are small-enough to fit into 1.4Mbytes, the Windows Installer can read those files. Remove the Windows Installation DVD (as it tells you), and insert the "burnt" CD/DVD. Yes, you can download the software, and 'unzip' it (if necessary), and burn the "unzipped" files onto CD-recordable media. It's convenient to do so, because you can tell the Windows Installer to "look" into a specific folder on the USB's "file-system" structure for the necessary files.
What's the manufacturer and model-number of your disk-drive? Within "BIOS SETUP", is the motherboard configured for "native" mode of operation of the disk-drive, and for 'AHCI' (not 'IDE-emulation') mode? If it is a non-HP motherboard, what is the manufacturer, and model-number?ĭoes that Installation Media come from HP, or is it a "retail" copy of Windows, or something you downloaded? What Operating System are you trying to install? So, what model-number of computer do you have?
Since the software is "required", not just "optional", it's probably the "full-function" device-driver software for your disk-drive, not just the "basic" device-driver software that is included. Support for CD/DVD optical devices is included in Windows NT/2000/XP/Vista/7/8/10. If you have that software, stored on CD media, or on a floppy (or "stiffy") diskette, or on a USB flash-drive, please insert that media into the matching port. What they mean is that Windows needs some device-driver software, to continue with installing Windows. If you have a floppy, CD, DVD or USB flash Drive, please insert it now"
> While loading Windows 7 64 bit for a new install from DVD, I get a message "a required CD/DVD drive device driver is missing. If you check the box, it will only include the compatible driver.įollow the prompts, and hopefully, W7 will install. You should now see the storage driver files listed. Get a USB flash drive, and copy the files in the folder to your USB flash drive.Īfter you select the install now option, select the Drive Options - Advanced menu, then select the Load Driver option. If that doesn't work, then try the iaStorA file.ĭownload and unzip the file to its folder. The first one I would try is the iaStorS file.
It would depend on what setting the BIOS's drive controller is set to. I don't know which one is the right one, unfortunately, so try them both.
I have zipped up and attached the two possible storage controller drivers your PC needs, below. If you are installing from a Microsoft W7 DVD, then that is probably not the issue.Īnother issue could that be W7 needs the storage controller drivers in order to proceed. You should burn the ISO file to a DVD at the slowest possible burn speed you can. Most often that occurs if you burned the ISO file yourself to a DVD. Hi, when you get that message, it is because the DVD is defective.
