大家下午好，
我已经将 ubuntu 安装在 XPS 13 2in1 的 SD 卡上。我无法从它启动，我想是因为没有 grub - 它只是把我踢进 Windows。
目前正在从 livecd 启动来尝试解决。
我有一个名为 /dev/nvme0n1 的混乱的 NVME 分区（感谢 Windows），其中
EFI system partition
Microsoft reserved partition
Basic data partition
a 700mb NFTS partition
9.76gb nfts image
1.09 nfts image
(sorry if that is utterly irrelevant - just thought i'd add it)
The sd card is /dev/mmcblk01
with EFI system partition fat32 512mib
an ext4 partition 732mib
[encrypted] 114.94
unallocated 1.00mib
I did choose lfvs encryption when installing as I wish to use this so that explains the [encrypted]!
Any advice on what to try next please?
