不能再加载Windows 10了

Question

我已经安装了RHEL 8和Windows 10。

我用过LVM。为/和/home挂载的pv /dev/sda1 1 (xfs)和pv /dev/sdc6 6 (xfs)卷组。用于/boot的/dev/sdc5 5 (xfs)

现在，我没有在grub列表中看到Windows。试图添加到/etc/grub.d/40-custom/

menuentry "Windows 10" {
insmod part_gpt
insmod fat
set root='(hd0,gpt2)'
search --no-floppy --fs-uuid --set=root 0CC3-C99F
chainloader +1
}

输出：blkid：

我不明白为什么Windows 10没有启动。非常感谢。

我也是双重引导，这里有一个正确的GRUB2条目，用于在启用UEFI的系统上引导Windows：

menuentry 'Windows Boot Manager (on /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-efi-ABCD-EF01' {
    insmod part_gpt
    insmod fat
    set root='hd0,gpt1'
    if [ x$feature_platform_search_hint = xy ]; then
      search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci1,gpt1  ABCD-EF01
    else
      search --no-floppy --fs-uuid --set=root ABCD-EF01
    fi
    chainloader /EFI/Microsoft/Boot/bootmgfw.efi

您需要替换的内容：

ABCD-EF01 ->您的EUFI系统分区UUID，可能是0CC3-C99F

hd0 -> with (从0开始)，可能是hd2

gpt1 ->使用UEFI文件的分区(从1开始)，可能是gpt2
