Boot from 4TB NVMe #
The Raspberry PI Imager creates max 2TB partitions as MBR type. If you want to use a 4TB SSD as boot device you need this instructions.Approach in short
- Install Raspberry PI OS on SD Card
- Use GPT table on NVMe and create same type of partitions on NVMe like on SD card
- copy over both partitions data
- switch boot order
1. Prepare SDF Card#
I will use terminal only, so I use lite version:- Raspberry Pi Imager > Raspberry PI OS (Other) > Raspberry PI OS Lite (64-bit)
2. Prepare NVMe#
We create same partitions like in SD-Card, check out SD-Card first:> sudo fdisk --list [...] Device Start End Sectors Size Type /dev/nvme0n1p1 8192 1056767 1048576 512M Microsoft LDM metadata /dev/nvme0n1p2 1056768 7814035455 7812978688 3.6T Linux filesystem Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 8192 1056767 1048576 512M c W95 FAT32 (LBA) /dev/mmcblk0p2 1056768 15597567 14540800 6.9G 83 Linux
Create
> sudo fdisk /dev/nvme0n1 create GPT first, this enables us to use MORE than 2TB ! > g create first partition: 512MiB boot partition. 4MiB before partition. fat32. Label as ‘bootfs’ > n (new partition) Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p): p Partition number (1-4, default 1): USE exact size from former SD-card (see >sudo fdisk --list<), e.g. 8192 - 1056767 > t (change partition type) > 11 = Microsoft basic data !!! - "efi system partition" should work too(?) create second partition ext4 partition > n > primary > (defaults) note: partition type "Linux" = ext4
