Debian-Installer doesn’t load Firmware from USB

Recently, I was installing my Lenovo Ideapad U-410 with debian 9.1.0 via USB through UEFI. I thought use the wifi interface for such task. I take care about use a USB with FAT 32:

mkfs.vfat /dev/sdX#

mount it:

mount /dev/sdX# /media/silverdog/

and copy the firmware from a Lenovo that is working now with iwlwifi (lucky bas….).

cp /lib/firmware/iwlwifi-2030-6.ucode /media/silverdog/ && sync && umount /media/silverdog

Everything looks good at the moment. The installer ask to insert a USB to install the firmware and press enter. Astonishingly, the dialog returned to the same screen asking for the same firmware!

The console #4’s log (Alt + F4) shows how the installer is trying to mount every device. Unfortunately, this laptop has a 22GB mSATA with 4 partitions, 1TB HDD with 2 partitions, 1 usb with the debian-installer and 1 usb with the firmware in it. It’s very weird that the installer wasn’t able to mount the usb. A fast search in google doesn’t show much information to solve it quickly, but the log show that he’s trying to mount in /media/. So, should I mount it manually? YES..

Alt + F2 …. Enter

mount /dev/sdd1 /media/

Alt + F1 …. Enter

What happened? ………… It Worked!
