I can see that you have a not USB-attached SD/MMC card reader. Most BIOSes doesn't support booting from it at all or need special layout (like putting floppy image on a FAT). Consult info of your BIOS

- HP Mini 1000
- Boot device: USB key or SD-card


% ./configure && make && make install
% .grub-mkrescue --image-type=floppy rescue.img
# dd if=`pwd`/rescue.img of=/dev/mmcblk0 bs=1M
1+1 records in
1+1 records out
1474018 bytes (1.5 MB) copied, 0.179898 s, 8.2 MB/s

Then boot on the SD-card using [F9] key.

The machine starts loads something & reboot (return on BIOS screen).  No error message is visible.


It seems that this always happens when core.img includes an actual memdisk.  Whether the memdisk image is generated by "cpio -o" or "tar -cf" does not change this.

Booting without an included memdisk image (without the -m parameter of grub-mkimage) but with the memdisk, loopback & cpio modules works: It allows to manually examine the memdisk image file content, which is Ok.
