sdbでエラーというのは、別にGRUB driveじゃないので問題なし。
さーて、これで再起動…ありゃ、やっぱりWin10が起動しちゃってgrub来ないじゃないのどうなってるの？ ふたたび、Live USBで起動して/dev/sda2をマウントして見てみると…相変わらず/Ubuntuディレクトリがない。それだけでなく、/EFIディレクトリ自体が、nautilusで表示しようとするとIOエラー！ そこでアンマウントしてfsckしてみると…またファイルエラーかいな。うーん、元のHDDがくたびれていたから、不整合なファイル管理情報もぜんぶまるっとコピーされちゃったんだろう、と想像はつくけれども、じゃあパーティションの切り直しから再インストールまでぜんぶやらないとダメか？？？
悪あがきしてみよう。Ubuntuでfat32フォーマットをする方法を確認。
かえでのWebログ
LinuxにおけるFAT32フォーマットの方法
2008/09/12
実際にmkfsコマンドを利用してフォーマットする。$ sudo mkfs.vfat -v -c -F 32 /dev/sde1
-v詳細な進捗を表示-c不良ブロックの精査を行う-F 32 FAT32形式でのフォーマットの指定。-FだとFAT(16)となる。
よーし。
$ sudo mkfs.vfat -v -c -F 32 /dev/sda2
そして、再度、元のHDDの第２パーティションをまるっとコピー。
めでたくSSDからUbuntu起動。ただし、grubのメニューが出ないので、SSDから起動したUbuntuで
$ sudo update-grub
で完了。
なお、grub-install時のchrootについて説明してくれている所。

そしてchroot /mnt を使って /mnt を / として扱います。なぜにchrootを使うのかというと、参考資料にもあるとおり$ sudo grub-install /dev/nvme0n1 Installing for i386-pc platform. grub-install: error: failed to get canonical path of `/cow'.これが出てしまうためです。
親切な方々に感謝。
