Fedora boots up slower than any other distro. How can I improve the boot time? Also, I installed fedora using the network installer, I cannot find the bootloader config file to remove the boot menu wait time. Where is the systemd-boot loader.conf located??
Fedora uses grub2 by default. You can find a the setting for grub timeout and regeneration of grub config in After the last update, GRUB timeout was set to 5 seconds - #2 by augenauf
Re boot time:
first, analyze why your boot time is longer than expected:
systemd-analyze
systemd-analyze blame
systemd-analyze critical-chain
NB. In future, please start one topic per each question, that makes it easier to mark a solution and easier to find the right answer for other users.
