很奇怪，按照报错信息，他说有其他可启动的分区，但查看VNC的时候发现只有Ubuntu和Reinstall脚本。


Start with the /reinstall.log output and the generated /boot/grub/custom.cfg entry after running reinstall.sh ubuntu-24.04. Reproduce the reboot on Ubuntu 22.04 with the shown cloud image and inspect why /reinstall-vmlinuz is not found; done means the reinstall entry boots successfully or the failure is clearly diagnosed.
