When I run Linuxboot on a server that can boot into the operating system normally, I enter localboot -grub -d on the u-root command line but I can't recognize the hard disk in the system, and when I can directly find the grub configuration on another server and boot into the operating system, is there any problem with localboot?

**u-root command line input
/#localboot -grub -d
/#mounted: []
/#No boot configuration found
