Multiboot USB Drive
===================
Write up of my install process.
Arch Wiki: [Multiboot USB Drive](https://wiki.archlinux.org/index.php/Multiboot_USB_drive#Hybrid_UEFI_GPT_.2B_BIOS_GPT.2FMBR_boot)
GRUB configs based off [aguslr/multibootusb](https://github.com/aguslr/multibootusb) and [thias/glim](https://github.com/thias/glim).
Theme based of [Generator/Grub2-themes](https://github.com/Generator/Grub2-themes).
## 1. Partition disk
| # | Name | Type | Size | File system |
|---|------------------|------|------|-------------|
| 1 | BIOS Boot | EF02 | 1MB | - |
| 2 | EFI System | EF00 | 50MB | fat32 |
| 3 | Linux filesystem | | rest | ext4 |
```
$ parted /dev/sdX -l
Model: Kingston DataTraveler 150 (scsi)
Disk /dev/sdb: 32.3GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB BIOS boot partition bios_grub
2 2097kB 12.9GB 12.9GB fat32 EFI System boot, esp
3 12.9GB 32.3GB 19.4GB ext4 Linux filesystem
```
## 2. Create "Hybrid MBR Partition Table"
```
$ gdisk /dev/sdX
Command (? for help): r
Recovery/transformation command (? for help): h
Type from one to three GPT partition numbers, separated by spaces, to be added to the hybrid MBR, in sequence: 1 2 3
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): N
Creating entry for GPT partition #1 (MBR partition #2)
Enter an MBR hex code (default EF):
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #2 (MBR partition #3)
Enter an MBR hex code (default EF):
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #3 (MBR partition #4)
Enter an MBR hex code (default 83):
Set the bootable flag? (Y/N): Y
Recovery/transformation command (? for help): x
Expert command (? for help): h
Expert command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): Y
```
## 3. Format filesystem
```
$ mkfs.msdos -F 32 /dev/sdX2
$ mkfs.ext4 /dev/sdX3
```
## 4. Mount
Using `/mnt/efi` and `/mnt/data` as mount points.
```
$ mount /dev/sdX2 /mnt/efi
$ mount /dev/sdX3 /mnt/data
```
## 5. GRUB Install
Install for EFI:
`$ grub-install --target=x86_64-efi --efi-directory=/mnt/efi --boot-directory=/mnt/data/boot --removable --recheck`
Install for BIOS:
`$ grub-install --target=i386-pc --boot-directory=/mnt/data/boot --recheck /dev/sdX`
As additional fallback, install for MBR-bootable data partition:
`$ grub-install --target=i386-pc --boot-directory=/mnt/data/boot --recheck /dev/sdX3`
EDIT last command:
```
Installing for i386-pc platform.
grub-install: warning: File system `ext2' doesn't support embedding.
grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.
```
"Fixed" with `--force`...
## 6. GRUB Configure
1. Copy ISOs to `[/mnt/data]/boot/iso/`
2. Update ISO file names in `grub.d/` configs
3. Copy over files (`$ ./copy_files.sh /mnt/data/boot/grub/`)
## 7. World Domination
