もとの実マシンでなく仮想マシンから持ってきたので，厳密な意味での “復旧” ではありません．しかし，Debianの実マシンが復活したので，広い意味での復旧ということにします1<\/a><\/sup>利用した仮想マシンはもともと実マシンのクローンとして作成したので “復元” に近いといえます．<\/span>．<\/p>\n\n\n\n

結局最終的に成功したのは，Manjaroの実マシンにDebianのパーティションを適当な場所（たとえば\/mnt\/hd<\/code>）にマウントして，<\/p>\n\n\n\n

root #mount --types proc \/proc \/mnt\/hd\/proc\nroot #mount --rbind \/sys \/mnt\/hd\/sys\nroot #mount --make-rslave \/mnt\/hd\/sys\nroot #mount --rbind \/dev \/mnt\/hd\/dev\nroot #mount --make-rslave \/mnt\/hd\/dev\nroot #mount --bind \/run \/mnt\/hd\/run\nroot #mount --make-slave \/mnt\/hd\/run <\/pre>\n\n\n\n
という具合にお膳立て<\/a>してから，<\/p>\n\n\n\n
root #chroot \/mnt\/hd \/bin\/bash\nroot #source \/etc\/profile\nroot #export PS1=\"(chroot) ${PS1}\"<\/pre>\n\n\n\n
として，さらにDebian実マシン用のEFIにしている\/dev\/sda1\u3092\/boot\/efi<\/code>にマウントしてから，UEFI+Grub2<\/a>の手順にしたがって，EFIとGrubをインストールしました．<\/p>\n\n\n\n
一年前の実マシンのバックアップからの復旧も試してみます．<\/p>\n\n\n\n
