Repartitioning your Pinebook Pro
There are multiple reasons to desire a different file system layout. In my case, I want to separate the OS from user data.
Make a backup
Backup your existing OS and data. Multiple times if it's important data.
Understand the risks
If you perform the steps wrong, you could end up with an un-bootable laptop. Even using a SD card may not help. If the eMMC thinks it's good enough to boot, it may not try the SD card.
Read about recovery options
Worse case, you may have to open up your Pinebook Pro and perform a boot with
Using a MicroSD card
This example shows using a SD card as temporary boot location.
Partitioning the eMMC
As user "root", perform the following steps:
- Wipe the existing partition table
- Create new, empty GPT partition table
- Create the boot support partitions;
# sfdisk /dev/mmcblk1 --wipe always --label GPT <<EOF unit: sectors first-lba: 64 /dev/mmcblk1p2 : start= 64, size= 16320, type=8DA63339-0007-60C0-C436-083AC8230908, uuid=1B5A4130-0958-455D-B9AB-C1F2E232FFF8, name="IDBLoader", attrs="RequiredPartition" /dev/mmcblk1p3 : start= 16384, size= 8192, type=8DA63339-0007-60C0-C436-083AC8230908, uuid=D0972B65-4091-4E34-9A4C-8BD949C35E16, name="U-Boot", attrs="RequiredPartition" /dev/mmcblk1p4 : start= 24576, size= 8192, type=8DA63339-0007-60C0-C436-083AC8230908, uuid=6C5329F3-9A03-4664-A15C-44E869EDE05C, name="TrustedFirmware-A", attrs="RequiredPartition" /dev/mmcblk1p1 : start= 32768, size= 524288, type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7, uuid=3956C6AC-1AC8-4E45-A2A5-FD3CCA60D0CD, name="Linux-boot" /dev/mmcblk1p5 : start= 557056, size= 8388608, type=0657FD6D-A4AB-43C4-84E5-0933C84B4F4F, uuid=C1565C17-D5C2-410C-892E-7371CB22947D, name="Linux-swap" /dev/mmcblk1p6 : start= 8945664, size= 56598481, type=B921B045-1DF0-41C3-AF44-4C6F280D3FAE, uuid=E55D2252-DAC4-4EEB-AD41-D47F52B9889F, name="Linux-root" /dev/mmcblk1p7 : start= 65544192, size= 56598481, type=B921B045-1DF0-41C3-AF44-4C6F280D3FAE, uuid=FB2E55D1-EA3B-418F-BB54-B9E92DF813F7, name="Linux-root-alternate" EOF
