Tôi hiện đang chạy Ubuntu 21.10 và Windows 10. Tôi luôn thiết lập grub của mình theo cách tôi muốn bằng công cụ tùy chỉnh grub. Trong số các thay đổi khác (tất cả đều hoạt động), tôi đã thiết lập nó để nó khởi động từ phân vùng được khởi động lần cuối. Cài đặt này hoạt động vào ngày 20.04, nhưng hiện tại thì không. Thay vào đó, nó luôn cố gắng khởi động vào Windows.
CHỈNH SỬA: Đây là nội dung của/etc/default/grub:
# Nếu bạn thay đổi tệp này, hãy chạy 'update-grub' sau đó để cập nhật
# /boot/grub/grub.cfg.
