System: - mb: Intel Atom with ICH10R chipset - disk: USB stick with MBR; a single etx4 partition (also have HDD with the same config) - grub 2.0 on mbr - built LFS+BLFS 32bit
Original status: - On the old mb: - I can boot from both USB stick and HDD - on the same mb with updated BIOS version: - I can only boot from HDD (SATA port) - on the new BIOS with the same USB stick I can see grub menu, but any attempt to boot results in error (see top of the thread) > The question being, can you make a USB bootable just by switching the > filesystem? As I understand, grub is capable of reading ext4 (menu is shown) At this point I wonder what causes grub to fail... > And a thing I just came up with: does your ext2 USB have the "bootable" > flag set on its boot partition? I have ext4 with bootable flag (boots on working mb) Just to clarify another problem while trying to solve initial one: there was a suggestion to switch to gpt with a separate /boot partition formatted as ext2 without initrd, but I can't boot linux even on Core2 pc without initrd if rootfs is mapped via UUID.
