I suspect technical support does not provide such instruction to prohibit (with M$ corp) downgrading to windows 7. I was afraid of missing of drivers and crash of installation process, but win7 installed without additional problems. During win7 installation I completely remove all win8.1 partitions and reformatted SSD disk (win7 did not want to install to GPT disk). I tried many directories without success but suddenly win7 installed correct driver and installation continued!Ĥ. Directory must be provided exactly because autosearch of drivers does not work. After appearance of error in question I used win8.1 partition to find necessary driver. Boot from win7 DVD (BIOS parameters were set according to Fujitsu recommendation).ģ. So, I started win8.1 and copied win7 drivers from Fujitsu site to win8.1 partition.Ģ. I decided to copy Fujitsu drivers to existing win8.1 partition because win7 installer can use it.ġ.
But for DVD with drivers it was impossible because installer searches driver in the root only. Exact directory with driver must be provided.
This was unsuccessful because win7 installer cannot search correct driver in catalog tree. So there is the question: how to install USB driver if system cannot work with USB devices and laptop does not have normal SATA DVD drive?įirstly, I tried to use DVD disk with drivers downloaded from Fujitsu site. Without appropriate USB driver win7 does not see any flash disks and cannot work properly with USB DVD-drive. I solved this problem installing driver for newest USB controller after the error in question appeared.
