在完全不同的 SSD 上安装 Windows 10 后，Ubuntu 启动时间从几秒钟增加到整整一分钟。是什么原因导致了这个问题？有什么解决办法吗？
我使用以下分区方案：
sda 8:0 0 232,9G 0 disk
└─sda1 8:1 0 232,9G 0 part
nvme0n1 259:0 0 931,5G 0 disk
├─nvme0n1p1 259:1 0 128M 0 part
├─nvme0n1p2 259:2 0 243M 0 part /boot/efi
├─nvme0n1p3 259:3 0 7,5G 0 part [SWAP]
├─nvme0n1p4 259:4 0 232,9G 0 part /
└─nvme0n1p5 259:5 0 690,9G 0 part
其中 sda 是三星 850 Evo SSD，nvme0n1 是三星 970 Evo Plus SSD。
Ubuntu 版本是 20.04.4
blkid 输出：

检查启动日志时我发现了以下几行：
apr 02 00:17:16 systemd[1]: Reached target Host and Network Name Lookups.
apr 02 00:17:46 systemd[1]: systemd-fsckd.service: Succeeded.

跑步cat /etc/fstab让我：

# / was on /dev/nvme0n1p4 during installation

因此，据我所知，这个问题是由我在 sda 上安装 Windows 之前安装在 sda 上的旧 Ubuntu 的交换分区引起的。
