我尝试在 Dell Inspiron N411Z 上安装 Ubuntu 24.04 LTS 作为唯一的操作系统，删除了计算机上的 Windows 10。安装正确完成，并提示我重新启动计算机。重新启动后，出现一条消息，提示“未找到操作系统”。通过 Live USB 后，我在终端中运行了启动修复。我得到了以下链接：
============================= Boot Repair Summary ==============================
Recommended repair: ____________________________________________________________
The default repair of the Boot-Repair utility will reinstall the grub2 of
sda1 into the MBR of sda.
Grub-efi will not be selected by default because no ESP detected.
Additional repair will be performed: unhide-bootmenu-10s
======================= Reinstall the grub2 of /dev/sda1 =======================
chroot /mnt/boot-sav/sda1 grub-install --version
grub-install (GRUB) 2.12-1ubuntu7
==> Reinstall the GRUB of /dev/sda1 into the MBR of /dev/sda
chroot /mnt/boot-sav/sda1 grub-install /dev/sda
Installing for i386-pc platform.
Installation finished. No error reported.
chroot /mnt/boot-sav/sda1 update-grub

Adding boot menu entry for UEFI Firmware Settings ...
Unhide GRUB boot menu in sda1/boot/grub/grub.cfg
Boot successfully repaired.
You can now reboot your computer.
The boot files of [sda1 (end>100GB)] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)
