Excerpt from here: https://help.ubuntu.com/16.04/installation-guide/amd64/ch03s06.html#disable-fast-boot
"3.6.4. Disabling the Windows 8 “fast boot” feature - Windows 8 offers a feature called “fast boot” to cut down system startup time. Technically, when this feature is enabled, Windows 8 does not do a real shutdown and a real cold boot afterwards when ordered to shut down, but instead does something resembling a partial suspend to disk to reduce the “boot”time. As long as Windows 8 is the only operating system on the machine, this is unproblematic, but it can result in problems and data loss when you have a dual boot setup in which another operating system accesses the same filesystems as Windows 8 does. In that case the real state of the filesystem can be different from what Windows 8 believes it to be after the “boot” and this could cause filesystem corruption upon further write accesses to the filesystem. Therefore in a dual boot setup, to avoid filesystem corruption the “fast boot” feature has to be disabled within Windows. It may also be necessary to disable “fast boot” to even allow access to UEFI setup to choose to boot another operating system or debian-installer. On some UEFI systems, the firmware will reduce “boot” time by not initialising the keyboard controller or USB hardware; in these cases, it is necessary to boot into Windows and disable this feature to allow for a change of boot order."
So my question, I have Ubuntu 16.04 as the single OS installed on my laptop. I kept fast boot and secure boot enabled. Are there still risk? Is there any benefits to fast boot for Ubuntu only intall?
Thanks!
