.sfs files

with so little information
no

the only advice
provide more information

There are two ways you can install that SFS.
One is to select menu - system - Boot Manager configure bootup. Select the SFS file to be loaded on booting and add it. Then reboot. To remove it, just go through the same steps except remove it from the list and reboot.

The second way is to get and install one of the "on the fly" SFS loader utilities and use it.

there's a bunch of infos on the wiki about sfs
