Hello, TederbyKazuhiko
Based on the logs you provided, you seem to have no problems with the boot process.
It looks like updating the AMD Adrenaline driver did hit the problem of slow booting, which makes me happy for you.
Regarding the fastboot part, as far as I know, some computers need to select the corresponding boot method in the BIOS to adapt or enable fastboot, such as UEFI and Secure Boot, etc. There are also cases where fastboot is not supported, and you will need to seek support from the motherboard manufacturer for the specific BIOS settings.
Incidentally: fast boot technology is actually designed to enable hardware speed of the computer to boot quickly, such computers usually use slow mechanical hard drive, the performance of the CPU is not strong, etc., you use the SSD as the main drive to boot, fastboot has very little impact on your startup speed, you can be completely confident in its use.
Best Regards.
