Grubby Data Partition

If you've found this USB stick, please get in touch via ericteunis@deboone.nl, or +31613546355.

This is the data part of this USB stick.

Installation

There should be at least 3 partitions:

• #1: This data partition
• #2: A Bios boot partition
• #3: A simple EFI partition

There is a space of 8Gb left for temporary OS dding between partitions #3 and #1.

To install GRUB for both EFI and BIOS booting I used the following.

# these have to mounted!
DEV="/dev/sdb"
EFI_MNT="/tmp/grubby-efi"
DATA_MNT="/tmp/grubby"
# Make EFI
sudo grub-install --efi-directory="$EFI_MNT" --boot-directory="${DATA_MNT}/boot" --removable --recheck --target=x86_64-efi

# Make BIOS
sudo grub-install --boot-directory="${DATA_MNT}/boot" --removable --recheck --target=i386-pc "$DEV"

# Make Isos Directory
mkdir "${DATA_MNT}/boot"
