GRLDR has been integrated into the grub-extras ntldr-img module suitableįor use with GRUB 2, so I tried building wubildr.mbr from that no change,īut this gave me a modern baseline to work on. The first thing I did was to remember that Now, the messages shown in the bug report suggested a failure either within GRLDR as wubildr.mbr, and build a specially-configured GRUB core image as Supports doing this very thing for FAT, NTFS, and ext2. More, but it includes an assembly-language program called GRLDR that GRUB4DOS is based on GRUB Legacy, which is not of much interest to us any

Thus, you need something that is smallĮnough to be loaded by NTLDR, but that is intelligent enough to understand GRUB won’t fit in that: the smallest core.img you can generateĪt the moment is over 18 kilobytes. Unfortunately, NTLDR only loads 16 sectors - 8192 bytes -įrom disk. You might then think that you can just have the Windows boot loaderĬhain-load GRUB. Ubuntu is added as a boot menu option using BCDEdit. In a Wubi installation, NTLDR (or BOOTMGR in Windows Vista and newer) still SoĪll was more or less well, except for the elephant in the room. Use its built-in loopback facilities, and we were able to simplify this. When we switched to GRUB 2, we could instead The NTFS filesystem so that GRUB could read them, but this was overlyĬomplicated and error-prone. The kernel and initramfs from, though? Well, we used to copy them out to The initramfs loop-mount the root filesystem. Much trouble, and loopback mounts are well-understood so we can just have
