毎回すいません。

昨日、https://forums.ubuntulinux.jp/viewtopic.php?id=10518に回答していただいた中で、
>>ライブCDにディスクユーティリティ（システム→システム管理）があるのでしたらHDDの状態を確認してみればどうでしょうか。
と言う方法でext4を作ることができました。

しかし、今日、ubuntu10.10が起動しなくなりました（2回目
アップデートをし、再起動する時にできなくなりました。
たまにログインする画面までいくんですが、ログイン画面が出ずに止まってしまいます。

2回目なので、一度パーティションを削除し、もう一度ext4をつくろうとしました。

でも、毎回のごとくgpartedではエラー。

ディスクユーティリティでは前回できたんですが、できなくなりました。

◆修理について
◆これらの解決策、問題

どんな些細なことでもいいので回答よろしくお願いします。
