I'm new on this forum and happy to join to your community.
Now days i hardly try to solve my laptop problem with re-installing it's windows.
it has a Home premium 64bit windows with a sticky serial number.
My laptop Model is: Dell xps l501 A with two usb 3 socket.
the reason that i want to install the windows from a usb is my DVD rom has problems and can't reading any DVD disk,
So I created a bootable usb 3 windows installer with the official program and boot windows installer from it.
after a fast loading the language and location windows appeared and i hit the next and after that hit the install button.
after a fast loading this error page appeared:
"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
seems like the installer don't detect my flash drive , because in browse windows i can see only my pc drives and dvd rom drive.
the USB 3 driver is: Renesas USB 3.0 Driver
and this is the download link in exe format: Download Dell XPS L501X Notebook Renesas USB 3.0 Driver A02 Driver for Windows 7 x64 - Softpedia
to istalling the driver in installer i need the driver files with dat format.
