Can someone help me change from systemd-boot to grub, I want to have the option to boot. Into windows or arch when I launch and last time I tried this thing I bricked my is and had to reinstall arch

novel schooner Aug 20, 2024, 3:42 PM

#

sorry why are u moving to grub exactly?

patent harness Aug 20, 2024, 3:43 PM

#

so when i boot i can choose linux or windows

#

unless i can do that with systemd

novel schooner Aug 20, 2024, 3:49 PM

#

u should be able to boot windows with systemdboot using the efi chainloader

patent harness Aug 20, 2024, 3:52 PM

#

can i do that if windows is on a whole seperate drive

novel schooner Aug 20, 2024, 3:54 PM

#

if windows is on another drive its harder on systemd boot than in grub cause u need to change the systemdboot root fs but it can be achieved

#

anyways its a lot easier in grub

#

i would recommend u to use grub but not only for this, just because it is more complete than systemdboot

patent harness Aug 20, 2024, 3:55 PM

#

how hard is it to change over

novel schooner Aug 20, 2024, 3:56 PM

#

how many entries do u have in systemd boot

#

?

patent harness Aug 20, 2024, 3:56 PM

#

is there a way to check

#

3 when i boot i think

#

just rach and then another arch but compatability mode or smtn

#

idk i only use the first one

novel schooner Aug 20, 2024, 3:58 PM

#

yes the second one is the fallback boot i think

#

then it is not that hard to move to grub

patent harness Aug 20, 2024, 3:58 PM

#

yes it is fallback

novel schooner Aug 20, 2024, 3:59 PM

#

it is as simple as: getting any linux live iso with the necessary tools, completely nuke ur boot partition, install grub in it and create the config

patent harness Aug 20, 2024, 3:59 PM

#

so id loose all my stuff?

novel schooner Aug 20, 2024, 4:00 PM

#

no, if u are using uefi the partition u use to boot is different from the one u save ur files

#

are u experienced on linux and these things?

patent harness Aug 20, 2024, 4:01 PM

#

not particularly

#

oh yes looking at kde partition manager i see there is a third partition called boot lmao

#

just couldnt see it in my file manager

novel schooner Aug 20, 2024, 4:02 PM

#

ok no problem, so nuking ur efi system partition just deletes the kernels initramfs and that things

#

we can also delete just the necessary things for it to be easier to u

novel schooner Aug 20, 2024, 4:02 PM

#

patent harness just couldnt see it in my file manager

if u are using arch it is normally mounted at /boot

#

unless u changed it

patent harness Aug 20, 2024, 4:03 PM

#

novel schooner if u are using arch it is normally mounted at /boot

yep it is

novel schooner Aug 20, 2024, 4:03 PM

#

ok so do u want to move to grub then?

patent harness Aug 20, 2024, 4:03 PM

#

yessir

#

i dont think ive installed many kernel modules so i shouldnt have to reinstall much later

novel schooner Aug 20, 2024, 4:04 PM

#

the kernel modules are saved in ur root filesystem

#

not the efi partition

patent harness Aug 20, 2024, 4:04 PM

#

oh so im good anyway

#

sick

novel schooner Aug 20, 2024, 4:04 PM

#

in the efi partition just the kernel is normally saved

patent harness Aug 20, 2024, 4:05 PM

#

aight

novel schooner Aug 20, 2024, 4:09 PM

#

so are u using arch or other distro?

patent harness Aug 20, 2024, 4:09 PM

#

arch

novel schooner Aug 20, 2024, 4:10 PM

#

ok send please the following commands

#

lsblk

#

ls -l /boot

why do u have syslinux?

#

are u on uefi right?

patent harness Aug 20, 2024, 4:11 PM

#

novel schooner are u on uefi right?

i believe so

#

idk why i would have that 🤷‍♂️

novel schooner Aug 20, 2024, 4:14 PM

#

idk

#

so before all send ur systemd entries to have the reference if something goes wrong

ye ok valid

patent harness ```total 57008 -rwxr-xr-x 1 root root 81920 Jul 9 22:35 amd-ucode.img drwxr-...

so from here u have the following files that u do not need to remove: amd-ucode.img, the initramfs files, vmlinuz-linux

#

the rest can all be deleted

#

cause they are directories containing the systemd boot files

light flame Aug 20, 2024, 4:49 PM

#

he can just delete everything on the /boot

#

i don't remember if uninstalling bootctl does that too

novel schooner Aug 20, 2024, 4:49 PM

#

yes but then we avoid reinstalling kernels and initramfs later

#

he does not know much about these things so i thought it would be better like this

light flame Aug 20, 2024, 4:50 PM

no better time to learn than now dogekek

Sorry to interrupt but you probably don't want a 50 gb root partition empty

#

Unless you don't use any software lol

novel schooner Aug 20, 2024, 7:04 PM

#

honestly it isnt that bad

#

he has a /home with 800gb

#

most of the files are saved inside /home

wild condor Aug 20, 2024, 7:20 PM

#

I have 16gb of installed packages and I've been using Linux for like 6 months

novel schooner Aug 20, 2024, 7:31 PM

#

how many packages do u have

#

installed

#

anyways if u have 16gb used, to 50 theres a lot of space

neon quest Aug 20, 2024, 7:32 PM

Shouldn't we bring the convo back to systend to grub?

#systemd to grub
