Thanks, adrian15! Your info was able to help me drill down farther to the error.
It looks like grub is hanging on this line of the source: file: stage2/bios.c line: err = biosdisk_int13_extensions ((read + 0x42) << 8, drive, &dap); biosdisk_int13_extensions is an assembler function, so I'm not really sure how to figure out what line in the assembly it is hanging on. If anyone has any ideas on what is happening in this function, or how to possibly debug this further I'm all ears. adrian15, You mentioned that to work around this error I should link the stage1 to the stage2 directly. I'm not exactly sure how to do this. Do you have a link to where this is in the documentation? I have of source tried in the past to rerun grub-install and also the manual grub command to install, but this never had any effect. I have also tried to zero out grub in the MBR using dd and reinstall and this also never worked. Tracy, I think that your issue may be different than mine, but I'm not 100% sure on that. I have read that if your grub directory becomes corrupt this can cause the hang as well. In my case, I have verified that there is no difference in the files between a working and non-working setup, so corruption isn't to blame. Are you sure that the USB device you are installing grub on isn't buggy? I would try to recreate your filesystem and check for badblocks.
