Hello, I have seen a couple of posts on the internet about this, but none of them managed to help me, so I'm making a new one. Basically I decided to make a dual boot on my machine by adding arch a few months back (so I am Windows11/Arch). Everything worked well until a few days ago where for some unknown reason, when booting I was sent directly to the Windows log in manager. Tried rebooting and GRUB just won't show up. The partitions still exist but it says they are untouched (265GB/265GB of space). Went on the UEFI settings and in the booting menu it only gives me the Default windows booting as an option. I have no idea what might have caused this (maybe an update that I didn't notice). Tried looking around but I don't want to mess things up with the risk of deleting everything. Any advice would be greatly appreciated !!

first of all: https://wiki.archlinux.org/title/Dual_b … ibernation
- check if secureboot got re-enabled
- is this a laptop? we had a few topics recently with bad uefi implementations
- to create a new boot entry for grub boot an install media, mount your partitions, arch-chroot and either use efibootmgr for manual or re-install grub to let it do its thing

Hey, sorry for the late reply but I didn't have time to work on it. It works now ! I re-installed GRUB, but it wasn't detecting the Arch partition, and that's because apparently there were no more linux files in /boot. So I re installed linux, updated grab config and it worked. Thank you so much for your help !

where's your ESP mounted to?
"no more files in /boot" sounds to me like your ESP was mounted to /boot but now you changed it to (/boot)/efi
could also be that some windows update did someting to the ESP so it no longer got picked up by linux on boot (check dmesg for lines like "failed to mount /boot" and check fstab with lsblk)
