My nvme：
/dev/nvme0n1p1 = /boot/efi
/dev/nvme0n1p2 = archlinux-cwt /boot(Original image partition 3)
/dev/nvme0n1p3 = starfive-debian202510 /boot (Original image partition 3)
/dev/nvme0n1p4 = archlinux-cwt / (Original image partition 4)
/dev/nvme0n1p6 = starfive-debian202510 / (Original image partition 4, Upgraded to debian13.5, GPU VPU is working properly)
/dev/nvme0n1p7 = starfive-debian202510 /home
/dev/nvme0n1p8 = debian13.5 / (The official version was installed through debian ISO on a USB drive)
I have modified /boot/extlinux/extlinux.conf and /etc/fstab on nvme.
So, if my nvme capacity is large enough, I can install various system images that were originally booted on uboot onto nvme and boot them through grub.
The menu of Grub not be displayed on the monitor, but I can modify the default startup value of Grub to boot the required OS.
