Convert system drive from MBR to GPT! Compatible with Windows 10 and 11

2025/9/12 Edited to

... Read moreGPTディスクへの変換を考えているなら、まずは自分のシステムドライブがMBRかGPTかを確認するのがおすすめです。Windowsマークを右クリックし、「ディスクの管理」を選ぶと、各ディスクのパーティションスタイルが確認できます。 MBRには2TBの容量制限があるうえ、パーティションを最大4つまでしか作成できません。一方でGPTなら最大128個のパーティション作成や大容量ディスク全体の利用が可能です。さらに、起動時のパフォーマンス向上やセキュリティ機能も強化されるため、特にWindows 11ユーザーにとっては必須の形式となります。 私の場合、500GB以上のSSDを使っていて、MBRのままだと容量が十分に活用できませんでした。Partition Assistantを使ってパーティション削除なしで簡単に変換できたので、安心して利用を続けられています。 変換の際はバックアップを取ることも重要ですが、Partition Assistantはユーザーフレンドリーで初心者にも扱いやすいです。無料でダウンロードでき、操作画面もわかりやすいため、試してみる価値がありますよ。
