I have a problem with USB booting. My laptop is Toshiba Sattelite A660-186. When I try to boot Linux installer/live cd from USB it works fine, but when I try to boot Windows installer it gives boot bcd error, and when booting to already installed Linux on pendrive(installed on HDD works fine), grub displays an "unknown filesystem" error. Is there a fix or do I have an old, not supported motherboard? Already tried to change some bios settings like usb legacy emu(turning it off doesn't even list usb drive in boot list) and controller to AHCI/compatibility(didn't change anything).
