By selecting “Fast Boot” in the BIOS settings, the boot time becomes shorter.
My question is: how does it work?
Is it leaving aside certain features? Or, is it loading certain things after the boot?
What are the downsides of choosing this option?
Windows 10’s Fast Startup (called Fast Boot in Windows 8) works similarly to the hybrid sleep mode of previous versions of Windows. By saving the operating system state to a hibernation file, it can make your computer boot up even faster, saving valuable seconds every time you turn your machine on.
Valuable seconds. Omg, somebody's life depends on me booting up faster, because if I'm not in game in a few seconds, they'll die.
With an SSD, it's averaging 2-5 seconds faster, but possible complications far outweigh the Valuable seconds saved.
Turn on pc, sit down, make your butt comfortable, open keyboard draw, move mouse, crack fingers and neck. Oh boo, pc is already booted and I missed the process. Fast boot also has multiple issues with legacy equipment, CSM, older drivers, prior OS compatability in programs and a heap of little things many ppl don't see. It's especially bad during diagnostics of gpu, Lan or other issues as ppl shutdown, which saves the prior, corrupted state then returns the issue on reboot.
For a desktop, it's pretty much useless, it's main purpose is for laptop use, but Windows itself is a multiplatform OS, so includes both.
I would wager that a LOT of the boot loop complaints we see after crashes are caused--at least in part--by the use of fastboot.
"When you shut down a computer with Fast Startup enabled, Windows locks down the Windows hard disk. You won’t be able to access it from other operating systems if you have your computer configured to dual-boot. Even worse, if you boot into another OS and then access or change anything on the hard disk (or partition) that the hibernating Windows installation uses, it can cause corruption."
