I am trying to install Windows 7 on a dedicated partition on a Thinkpad T460s that is currently running Ubuntu 18. I created the partition with gparted, and I created the bootable USB using Rufus from a Windows PC.
Running gdisk -l /dev/nvme0n1 says that my disk is GPT.
These are my current partitions, the n1p4 should be dedicated to windows:
From the BIOS I deactivated secure boot and use UEFI. The USB boots properly, lets me pick language and keyboard layout and lets me click on the big Install button. The problem is at this point: the process stops, saying
“A required CD/DVD drive device driver is missing”
This is the error I get:
I know that the ISO I use is correct, because I tested it on a VM, so that should not be the problem. I tried creating the USB with different softwares, I tried unplugging it and plugging it back in, I tried changing USB port and I tried changing USB stick. Nothing helped.
At this point, I would be ok with having a clean Windows install and only afterwards putting Linux as dual boot, but given that I can't install Windows at all, this is currently not an option.
The best solution would be being able to install windows in the dedicated partition that I created. Any help is really appreciated.
