I am seriously racking my brain on this one. I have tried just about everything that I can find and think of to get this to work. Now I have two different models of Lenovo one is a desktop and one is a laptop.
Laptop: Lenovo thinkpad E560 i5 6200u 4GB ram 500GB hdd. https://www.cdw.com/shop/products/Lenovo-ThinkPad-E560-20EV-15.6in-Core-i5-6200U-4-GB-RAM-500-GB-HDD/3890879.aspx?pfm=srh
Desktop: Lenovo thinkpad m900 Tiny i5 6500t 4GB ram 500GB hdd https://www.cdw.com/shop/products/Lenovo-ThinkCentre-M900-10FM-Core-i5-6500T-2.5-GHz-4-GB-500-GB/3902931.aspx?enkwrd=10FM0007US&pfm=srh
Here is my issue. I have a custom image for the place that I work at, that is installed on a bootable usb created from rufus. I know this has not been corrupted because it works on older systems without any issue. When I load this image on either machine I can get past the section where you chose the language and time ect. Then it has a big button to install windows 7, after that point I get the message "A required cd/dvd drive device driver is missing. If you have a drive floppy disk, cd, dvd, or usb flash please insert now.
I have tried everything from uefi booting enable, legacy boot enable. There is even a usb emulation on the desktop model, the keyboard and mouse did not work without it when trying to pick the language and time.
The only thing that I have not been able to try is a usb 3.0 drive, as all the usb ports on both machines are usb 3.0. I have also seen another solution, go on the machine with a linux live and create a partition on the hdd and copy over the iso file for my custom image, and then boot from from that. This would be a last resort type of thing, there has to be a simple solution... Bleeping MS (or should i say intel).....
Sorry if this has already come up and a solution has been found.
