최근에 Dell XPS 9570을 구입했습니다. Windows와의 이중 부팅을 위해 Ubuntu를 설치하는 데 하루의 대부분을 보냈습니다. Nvidia 그래픽 카드 드라이버를 작동시키는 데 몇 가지 문제가 발생한 후 Ubuntu 파티션을 삭제하고 다시 설치하기로 결정했습니다. 그런데 이제 설치하려고 하면 설치할 수 있는 위치에 "/dev/sda"만 표시됩니다. Grub보다 Windows를 우선시하도록 부팅 순서를 변경한 후에도 Windows는 여전히 정상적으로 부팅됩니다. 라이브 CD에서 부팅 복구를 실행해 보았더니 결과는 다음과 같습니다.

귀하의 노트북이 NVMe 스토리지를 사용하고 있다고 생각하므로 드라이브와 파티션에는 sd가 아닌 nvme 접두사가 있어야 합니다. 내 NVMe 노트북 드라이브에서는 다음과 같습니다.
ls -la /dev/nvme0*
crw------- 1 root root 242, 0 Jun 7 10:27 /dev/nvme0
brw-rw---- 1 root disk 259, 0 Jun 7 10:27 /dev/nvme0n1
brw-rw---- 1 root disk 259, 1 Jun 7 10:27 /dev/nvme0n1p1

brw-rw---- 1 root disk 259, 6 Jun 7 10:27 /dev/nvme0n1p6
내 시스템의 첫 번째 저장소는 nvme0n1이며 여전히 fdisk를 사용하여 구성할 수 있습니다.
sudo fdisk /dev/nvme0n1
Welcome to fdisk (util-linux 2.31.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

추신: @Terrance 말이 맞습니다. 보시는 sda는 USB 부팅 드라이브입니다.
