GRUB2 - > Buildroot裏面：在蠐螬的BIOS設置

Question

分割故障我工作的Ubuntu 17.04上Buildroot裏面，2017年5月2日（我的配置：is here），並希望作爲引導程序GRUB2使用。

我建立的buildroot，我下面內建指令：

dd if=/dev/zero of=170831_disk_1.img bs=1M count=300 
cfdisk 170831_disk_1.img 
    dos -> primary & bootable & 0x83 
sudo losetup -f 170831_disk_1.img 
sudo partx -a /dev/loop0 
sudo mkfs.ext4 -L root /dev/loop0p1 
sudo mount /dev/loop0p1 /mnt 
sudo tar -C /mnt -xf rootfs.tar 
sudo umount /mnt 

和公正的情況下運行（完當前目錄後：/home/user/buildroot/buildroot-2017.05.02/輸出/圖像/ 170831/）：

sudo ../../host/usr/sbin/grub-bios-setup -b ../../host/usr/lib/grub/i386-pc/boot.img -c grub.img -d . /dev/loop0 

而且我得到以下錯誤（詳細模式）：

我沒有解決這個問題，但我找到了另一個解決方案。如果您需要安裝GRUB2的buildroot的，只是使用genimage，並按照指令：

partition boot { 
    in-partition-table = "no" 
    image = "boot.img" 
    offset = 0 
    size = 512 
    } 
    partition grub { 
    in-partition-table = "no" 
    image = "grub.img" 
    offset = 512 
    } 
} 

此實用程序將GRUB2寫入到存儲。只要確保在已經存在的分區之前已經有大約1Mb的空間。

現在適合我。

P.S.在IRC#buildroot中，我被建議再次重新編譯所有內容，然後 尋找錯誤。它根本沒有幫助。
