まず、GPU(AMD Radeon RX560)を認識するところまで進めていきます。
①以下より、ServerイメージのISOをダウンロード
https://jp.ubuntu.com/download
②Windows11上のDVD書込みソフトで、ブートディスク作成
③デスクトップPCにインストール(Ubuntu Server)
④GUI環境インストール
```
sudo apt update
sudo apt install ubuntu-desktop
reboot
```
⑤再起動完了後、デスクトップ環境となった
⑥nvtopのインストール
```
apt install nvtop
```
⑦GPUの動作確認
```
nvtop
```
lspciで見てもちゃんと認識できている
```

★補足
本当は、unetbootinでUSBブートメディアでUbuntuインストールをしたかったのですが、なぜか途中でエラーとなるので上記に変更した
※そのうち分かるかな
Part2に続く
