Hi, either your automatically generated grub.cfg or the the one you added manually contains an incorrect UUID. I recommend editing grub.cfg manually. Find out what the correct UUID is, or label the partitions as I did, and edit the grub.cfg by hand. I’ve attached my (nearly perfect ;) grub.cfg. Admittedly, the way I handle the microcode is obsolete—, see the wiki link for more on that. https://wiki.archlinux.org/title/Microcode $ cat grub.cfg play 1920 440 1 0 1 880 2 0 1 880 1 0 1 440 2 set timeout=60 set color_normal=light-gray/black set color_highlight=white/light-gray set menu_color_normal=light-gray/black set menu_color_highlight=white/light-gray set default="1" insmod efi_gop menuentry " -- HAL 9000-m1 -----------------------------------------------------------------" { true } menuentry " MemTest86 V11+ Free" { search --set=root --no-floppy --fs-uuid 3F5B-F698 chainloader /EFI/memtest86/memtestx64.efi } menuentry " -- Arch Linux ------------------------------------------------------------------" { true } menuentry " Arch Linux threadirqs" { search --no-floppy --set=root --label m1.archlinux linux /boot/vmlinuz-linux root=/dev/disk/by-label/m1.archlinux ro threadirqs ipv6.disable=1 kvm.enable_virt_at_load=0 initrd /boot/intel-ucode.img /boot/initramfs-linux.img } menuentry " Arch Linux no zswap, no transparent hugepages" { search --no-floppy --set=root --label m1.archlinux linux /boot/vmlinuz-linux root=/dev/disk/by-label/m1.archlinux ro ipv6.disable=1 kvm.enable_virt_at_load=0 zswap.enabled=0 transparent_hugepage=never initrd /boot/intel-ucode.img /boot/initramfs-linux.img } menuentry " Arch Linux" { search --no-floppy --set=root --label m1.archlinux linux /boot/vmlinuz-linux root=/dev/disk/by-label/m1.archlinux ro ipv6.disable=1 kvm.enable_virt_at_load=0 initrd /boot/intel-ucode.img /boot/initramfs-linux.img } menuentry " Arch Linux Longterm" { search --no-floppy --set=root --label m1.archlinux linux /boot/vmlinuz-linux-lts root=/dev/disk/by-label/m1.archlinux ro ipv6.disable=1 kvm.enable_virt_at_load=0 initrd /boot/intel-ucode.img /boot/initramfs-linux-lts.img } menuentry " Arch Linux Rt" { search --no-floppy --set=root --label m1.archlinux linux /boot/vmlinuz-linux-rt root=/dev/disk/by-label/m1.archlinux ro ipv6.disable=1 kvm.enable_virt_at_load=0 initrd /boot/intel-ucode.img /boot/initramfs-linux-rt.img } menuentry " -- Other Linux -----------------------------------------------------------------" { true } menuentry " Alpine Linux" { search --no-floppy --set=root --label m1.alpine linux /boot/vmlinuz-lts root=/dev/disk/by-label/m1.alpine ro modules=ext4 initrd /boot/initramfs-lts } menuentry " Xubu 20.04 Linux 6.2.9-custom" { search --no-floppy --set=root --label m1.xubu20.04 linux /boot/vmlinuz-6.2.9-custom root=/dev/disk/by-label/m1.xubu20.04 ro initrd /boot/initrd.img-6.2.9-custom } menuentry " Ubuntu X Moon Studio lowlatency" { search --no-floppy --set=root --label m1.archlinux linux /.boot/ubuntu_moonstudio/boot/vmlinuz-lowlatency root=/dev/disk/by-label/moonstudio ro initrd /.boot/ubuntu_moonstudio/boot/initrd.img-lowlatency } submenu " *buntu -- Submenu --" { menuentry " Xubu 20.04 Linux 6.2.9-custom (recovery mode)" { search --no-floppy --set=root --label m1.xubu20.04 linux /boot/vmlinuz-6.2.9-custom root=/dev/disk/by-label/m1.xubu20.04 ro recovery nomodeset initrd /boot/initrd.img-6.2.9-custom } menuentry " Xubu 20.04 Linux 5.4.0-42-generic" { search --no-floppy --set=root --label m1.xubu20.04 linux /boot/vmlinuz-5.4.0-42-generic root=/dev/disk/by-label/m1.xubu20.04 ro initrd /boot/initrd.img-5.4.0-42-generic } menuentry " Xubu 20.04 Linux 5.4.0-42-generic (recovery mode)" { search --no-floppy --set=root --label m1.xubu20.04 linux /boot/vmlinuz-5.4.0-42-generic root=/dev/disk/by-label/m1.xubu20.04 ro recovery nomodeset initrd /boot/initrd.img-5.4.0-42-generic } menuentry " Ubuntu X Moon Studio liquorix threadirqs" { search --no-floppy --set=root --label m1.archlinux linux /.boot/ubuntu_moonstudio/boot/vmlinuz-liquorix root=/dev/disk/by-label/moonstudio ro threadirqs initrd /.boot/ubuntu_moonstudio/boot/initrd.img-liquorix } } menuentry " -- System ----------------------------------------------------------------------" { true } menuentry " UEFI Firmware Settings" --id 'uefi-firmware' { fwsetup } menuentry " Restart" { reboot } menuentry " Shutdown" { halt } menuentry " --------------------------------------------------------------------------------" { true }
