如何使GRUB检测Windows启动分区？
如何使GRUB检测Windows启动分区？
提问于 2022-06-17 13:21:19
我使用的是双引导Windows/Kali linux，由于最新的grub更新，Windows条目被删除。
当我从BIOS启动时，Windows引导分区可以工作，但不知怎么我无法让GRUB自动将它添加到它的配置中。
适当地检测到操作系统：

按照@artem-s-tashkinov的建议，我手动添加了/etc/grub.d/40_custom条目，方法是基于grub备份(/etc/grub.d/backup/boot_grub/grub.cfg)编辑文件update-grub，替换UUID并运行D2。
╰─❯ cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry "Windows 10" --class windows --class os $menuentry_id_option 'osprober-efi-' {
insmod part_gpt
insmod fat
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root 7A03-CA46
else
search --no-floppy --fs-uuid --set=root 7A03-CA46
fi
chainloader /efi/Microsoft/Boot/bootmgfw.efi
}这个很好，谢谢。
