Kyles503 · Jul 9, 2013

Im downloading windows by USB and the .iso is from here:
http://www.pcworld.com/article/248995/how_to_install_windows_7_without_the_disc.html

Every time i try and install it says: "A required CD/DVD drive device driver is missing"

My Motherboard is the msi z87-g41.
My hard drive is the first thing that boots up and is on ACHI mode.

What should i do.

does anybody have an idea on how i can get my pc work

smorizio · Jul 9, 2013

On the Pc you downloaded the Iso too and the windows tool. Run the tool with a four gig USB stick. When it done you should have a bootable install USB stick. On the new pc you have to make the USB stick the first boot devices.

what else should i try?

can anyone help me???

smorizio · Jul 9, 2013

Make sure in the bios efi cd rom or other devices are not the first boot device. On most mb hit f11 pull up a boot menu.

i have the usb as the first thing that boots

Now the problem would be that it cannot find the drivers for installation:

Can you refer on this site:

This works by chances.

1- in error page click cancel, then close.
2- go back to the welcome screen.
3- change usb port
4- click on install
5- repeat step 1 to 4 till installation goes as usual.

commonly 1 try is enough.

Any suggestion of which SATA option to use in BIOS? The microsoft site suggests switching from AHCI to ATA. I've been running on RAID.

always with one sata drive or ssd set your sat controller to achi mode not to the old ide mode.

Doesn't work. I have tried it for every usb port I have.

Made a USB Flash drive with Win 7. Changed the USB port -before I tried to use first an external DVD drive with Win 7 installation DVD and than the same USB flash drive but at the same port as DVD drive. Turns out changing the USB port did the trick - it immediately started to install Windows - before I only had this 'required CD/DVD" message EVEN WITH my USB drive: it drove me nuts, computer says "missing cd/dvd" and I didn't even have a DVD drive connected.

This one also works on me. I have 3 usb slots on my alienware laptop, I tried all three and the 3rd one works. Thanks.

I've just had a similar problem with a Lenovo laptop. Using the inbuilt CD/DVD drive. I connected an external DVD drive and the operating system loads correctly from this drive.

If you are using the USB drive, then may be you have a faulty port, or a problem USB memory stick. Try changing both.

Thanks, guys. I've spent days and days in frustration trying to load Windows 7 Home Premium on my ACER notebook. Tried several different makes of USB sticks and got the same problem message about the CD/DVD drive device driver. Swopped the USB port at the Welcome page as suggested. Whoopee, it's progressed to the next stage ("Installing Windows", so I think it's working.

Hello.

Sorry for bumping this old thread, but I'm having that same error "Required dvd drive is missing". I've literally tried everything, including this fix. I've got an HP stream 11, and it's only got 2 usb ports. One 3.0 and one 2.0.

i've tried the cancel method about 10 times trying to see if it would work, but it just simply won't

Have there been any other fixes? I'm trying to install windows 7 ultimate 32bit using a 2.0 usb drive. Legacy is enabled of course. I've used Rufus, UltraISO and about 4 other programs to write the iso to the stick and still getting this error.

smorizio · Apr 20, 2015

tow things use the microsoft iso to usb tool here it free.
https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool
in your laptop boot look for secure boot or csm make sure it off or set to legacey or the mb wont boot off the usb sticks.

jwut · Apr 20, 2015

Legacy is definitely enabled, and just tried making the bootable drive with the Microsoft tool. Still no go. Tried the removing/reinserting method about 8 times too lol. Still no go :/ im beginning to wonder if there is something encrypted on the bios or some crap of this Stream 11 thats not allowing me to install the OS. The Stream line of laptops were designed for like the cloud and windows 8. I was highly doubting at first that it was just impossible that I wouldn't be able to reformat it with 7 but its beginning to look that way.
