I have 3 computers, and all were setup at different times using this guide: > [@HOWTO - GPT/UEFI install with full disk encryption: BTRFSonLUKS with separate root, home and pkg subvolumes; hibernation with a swapfile; auto-snapshots with easy system rollback (GUI); boot into snapshots](https://forum.endeavouros.com/t/howto-gpt-uefi-install-with-full-disk-encryption-btrfsonluks-with-separate-root-home-and-pkg-subvolumes-hibernation-with-a-swapfile-auto-snapshots-with-easy-system-rollback-gui-boot-into-snapshots/3782): > > Warning: Most of what is done here in this tutorial is now already implemented inside calamares installer! but … it can be useful for pure arch install… warning added by joekamprad 21.5.2022 Inspired by some posts from @TomZ I decided to have a (re-)go at btrfs, test its snapshot capabilities and the ease of restoring these, try different subvolume setups and check if calamares allows for an encrypted install. As a result I have decided to make the following my new default type of install… All have samsung ssds in them and bootup from putting in encryption password to login prompt was a matter of 10 seconds at most, now it is over a minute, and for my 2 slower machines multiple minutes. During this time disk activity is pegged (hard drive light is solid the whole time). Doing some searching I couldn’t find others that have the problem, but it’s quite annoying when rebooting or turning on from an off state, any suggestions? ---

You are the second person to report this. The other person did not find a solution yet it seems. > [@LUKS slow early boot](https://forum.endeavouros.com/t/luks-slow-early-boot/31247): > > Since the grub boot issue I have discovered my boot has become unbearable slow (again): Startup finished in 5.493s (firmware) + 1min 22.731s (loader) + 2.511s (kernel) + 8.851s (userspace) = 1min 39.587s graphical.target reached after 8.586s in userspace. I have a full disk encryption with LUKS and use brtfs. I’m aware of the other topis about this topic and the fact that early boot will not have the hardware acceleration as when using the live system. Previously I had changed the iter count… ---

wow, that’s pretty poopie of a response. If you read what I wrote I said that I have had no issues at all with this setup on 3 separate machines since the latest grub fiasco. So I’m not just searching for in general slow booting, my booting was fine up until the latest grub thing that seemed to have changed something. Thought I would throw that out there as I was searching for things that would have happened within the last couple weeks with other people. ---

Which version of grub do you have installed? The latest _grub-something-4_ is supposed to solve the slow boot some people have had complaints about. Sorry for my being harsh, somewhat? ---

It’s cool, I can see how it could have looked like how you thought it did. I’m experiencing the issue on the latest ( grub-install (GRUB) 2:2.06.r322.gd9b4638c5-4 ) It probably makes sense to deal with this in just one thread, so anyone else coming across this feel free to pop over here: [LUKS slow early boot](https://forum.endeavouros.com/t/luks-slow-early-boot/31247) ---
