Hi, I'm attemping to do a clean install on my ASUS UX32VD-DB71. The problem is that there is no disc drive on the laptop, and all 3 of the USB ports are 3.0. But as you guys may know, a USB 3.0 port isn't loaded until Windows has booted. Still, the bootable 2.0 USB was able to boot, but after a few clicks "Next", a window appeared saying ""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." It seems like the installer doesn't detect my 2.0 USB.

Any help please! I have an external DVD drive, but I also want to learn how to solve the problem.

When it ask for the driver hit cancel, you should be brought back to the welcome screen. Now unplug the USB stick and plug it into a different USB port. Then select install again. You should be gold after that.

Other things you can try are to try to remake your bootable usb stick with a fresh image of the OS, and Enable AHCI in BIOS.

I should mention I'm not sure how you made your bootable stick, but I recommend using Microsoft's tool. I'll find link.

sorry that I didn't mention it, but yeah, I dowloaded the iso from digital river, and used the official tool to make the usb.

I recently did some research, many people issued the same problem. One solution I found is putting the USB 3.0 driver into the installation stick. Here is the quote:
Quote:
Additionally, there has been reports that if you use a USB-stick to install Windows 7 it can complain that 'A required CD/DVD drive device driver is missing...' during install and won't let you proceed. This is because the Windows 7 install does not contain USB3 drivers to work properly with USB-sticks, and needs them loaded separately. Download the USB3_Intel_Win7_64_Z104225.zip package from Asus UX32VD driver page and extract it either to your USB windows 7 installation stick or any other media. Then you just point Windows 7 to that driver folder when it asks you to. Windows 7 should proceed to install as normal.


I did follow the instruction, but nothing changed. Maybe I misundertood the instruction somewhere. The part "Then you just point Windows 7 to that driver folder when it asks you to" is confusing to me. The flash stick won't be showed up, so how can I "point" the installer "to that driver" ? I also enabled the USB Legacy in the BIOS

Well, booting is done in the following way:
1. BIOS loads BOOTMGR (whether EFI or BIOS emulation...does not matter).
2. BOOTMGR loads the boot.wim image in RAM (reads it through BIOS/UEFI driver)
3. BOOTMGR gives control to the extracted-in-RAM image - at this point, the USB3 is lost as windows will kill all BIOS/UEFI control

So if you can see the HDD, I would recommend to put the driver on the HDD. Also, I see the laptop has a sd-card reader....maybe you could try with the driver on a sd-card (maybe it's a USB2 sd-card reader connected to a USB2 port).

well, I'm gonna replace the HDD by a SSD, and I want to install Windows on that SSD. So there is no use putting the driver on the HDD. And I tried the SD slot, not working either. It says " SD Card Read Error. Ctrl + Alt + Del to restart."

Guys, as I've searched a Thousand pages looking for a solution, I've found that the real bad guy here is really the USB 3.0 drivers that DO NOT come bundled in the Windows boot disks and it gets lost searching for its own installation files after booting...

There are 2 possible solutions: switch to a USB 2.0 usb stick and it goes like a breeze.... OR.... if you are like me and have ONLY 3.0 ports, download the 3.0 controller drivers and unzip all its files to the C: drive

click search, go through the drivers you downloaded and click next, it'll find the drivers, "install them" and come back with the same error again.

THIS TIME, since the drivers ARE installed, you should unplug the stick and plug it back in... click next and it should work.

Easy like a fatality...
