When installing into a LUKS partition on a UEFI hardware, grub-install generates an incomplete /boot/efi/EFI/altlinux/grub.cfg file: search.fs_uuid bd7feb40-5921-45d6-96d9-0f646f12956b root cryptouuid/f7fa2cedfd174a1cbe0b5ad7ed0c0776 set prefix=($root)'/boot/grub' configfile $prefix/grub.cfg As you can see, since the mandatory command cryptomount -u f7fa2cedfd174a1cbe0b5ad7ed0c0776 that must precede search.fs_uuid is missing, search.fs_uuid cannot find the root and the boot stops. Note that grub-mkconfig does not have this issue, it adds cryptomount commands where appropriate.
Fix is being tested in task #244809
