最近SSDドライブにLinux（MintOS）をインストールしました。私のハードドライブにもWindows 10があります。 WindowsはLinuxの前にインストールされました。
問題は、grubローダーがWindowsローダーを認識せず、Windowsから起動できないことです。
そのSSDには2つの異なるOSがあったことを覚えています。 grubメニューには問題がなく、そのOSがドライブに見つかりました。ただし、ハードドライブ（Windows）から起動するには、毎回BIOSを使用してください。
今の状況は同じです。ただし、SSDにOSが1つしかなく、Windowsを起動できません。ウィンドウを削除することはオプションではありません。
ブート回復でこの問題を解決したところ、ソフトウェアはオペレーティングシステム（os-prober？）とドライブなどを正しく検出しました。 GrubはLinux構成の良い紹介も提供しています。 Windowsが検出されましたが追加されていません... :(
修理を開始するときは、次のフラグを選択してください。
- グラップを再インストール
- 起動メニューを非表示にする
- sdb（linuxを含むSSD）にgrubをインストールします。別の/boot/efiパーティションが選択されていません。
- Windowsのスタートアップファイルの回復
- sdb3 linuxはデフォルトのブートオペレーティングシステムです。
起動回復ログは次のとおりです。
============================= Boot Repair Summary ==============================
Default settings: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub2 of
sdb3 into the MBR of sdb.
Grub-efi would not be selected by default because legacy Windows detected.
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sdb (ATA IR-SSDPR-S25A-12) disk!
User settings: _________________________________________________________________
This will install an obsolete bootloader (GRUB Legacy). Please backup your data before this operation.
The settings chosen by the user will reinstall the grub2 of
sdb3 into the MBR of sdb.
Grub-efi will not be selected by default because legacy Windows detected.
Additional repair will be performed: unhide-bootmenu-10s win-legacy-basic-fix
Quantity of real Windows: 1
========================= Reinstall the grub2 of sdb3 ==========================
chroot /mnt/boot-sav/sdb3 grub-install --version
grub-install (GRUB) 2.06-2ubuntu7.1
==> Reinstall the GRUB of sdb3 into the MBR of sdb
chroot /mnt/boot-sav/sdb3 grub-install /dev/sdb
Installing for i386-pc platform.
Installation finished. No error reported.
chroot /mnt/boot-sav/sdb3 update-grub

Warning: os-prober will be executed to detect other bootable partitions.
Its output will be used to detect bootable binaries on them and create new boot entries.
Unhide GRUB boot menu in sdb3/boot/grub/grub.cfg
Boot successfully repaired.
You can now reboot your computer.
Please do not forget to make your BIOS boot on sdb (ATA IR-SSDPR-S25A-12) disk!
============================ Boot Info After Repair ============================

grubにウィンドウを追加するには？
ベストアンサー1
1つの考えられる解決策は、ファイルにWindowsエントリを追加することです（「手動」と仮定）/etc/grub.d/40_custom。このエントリは実行時にupdate-grub自動的に追加されます。
正確なものは、Windowsブートローダおよび/またはその他の詳細によって試行錯誤がある可能性があります。
一例（/etc/grub.d/40_custom）。前の行はmenuentry...すでにファイルにあるので、次の項目を追加するだけです。
#!/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.
# Add this
menuentry 'Windows' {
insmod ntfs
insmod ntldr
insmod part_msdos
insmod search_fs_uuid
# the uuid would be of the partition where the bootloader is, I assume sda2
search --no-floppy --fs-uuid --set=root 715729d9-1ab0-4a3a-a829-b2a6a909e4e6
ntldr /bootmgr
}
コンテンツを追加して実行する必要がありますupdate-grub。
