wubi-move.sh

This is a bash script that migrates a Wubi install to a partition. The script is based on the wubi-move-to-partition script from Agostino Russo taken the Wubi Guide (https://wiki.ubuntu.com/WubiGuide).

The first version updated the wubi-move-to-partition script to correct a few problems and deprecated commands, as well as to update it to support Grub2. It only worked on Wubi installs from 9.10 and later.

The current version adds the following features:

1. Supports migration of a normal (non-wubi) Ubuntu install. This can be useful to create a working backup, move your installation between computers, or create a working copy to experiment with.
2. Supports migration of a Wubi install from just the root.disk file (option --root-disk= ). This can be performed from an Ubuntu live CD/USB or another Ubuntu install. The named root.disk must be a fully-contained, working Wubi install, or if there are separate virtual disks for /home and /usr these must be in the same directory as the root.disk. (This option does not support Wubi with grub-legacy i.e. originally installed prior to the 9.10 release).
3. It supports migration of a Wubi or Normal install that uses grub-legacy - however it will replace grub-legacy with Grub2 (only on the migrated install). It does not update the current install's menu.lst so it is recommended to always install the Grub2 bootloader (or modify menu.lst manually).
4. The option --shared-swap can be used if you will be sharing an existing swap partition with another install. It bypasses the 'mkswap' command to avoid modifying the UUID.
5. It supports the ability to migrate to separate /boot, /usr and /home partitions.
6. It suppors the ability to synchronize a migrated install (e.g. for a bootable backup)

Usage: sudo bash wubi-move.sh [OPTION] target_partition [swap_partition] e.g. sudo bash wubi-move.sh /dev/sda5 /dev/sda6

Migrate an ubuntu install (wubi or normal) to partition -h, --help print this message and exit -v, --version print the version information and exit --notes print the Assumptions and Notes, and exit --no-bootloader do not install the grub2 bootloader --shared-swap share swap partition with an existing install -y, --assume-yes assume yes to all prompts --root-disk= Specify a root.disk file to migrate --boot=</dev/sdXY> Specify a separate /boot partition --home=</dev/sdXY> Specify a separate /home partition --usr=</dev/sdXY> Specify a separate /usr partition -c, --check-only Check only - validate target partition(s) --resume Resume a previous migration attempt that ended due to copying errors (rsync). --synch Synchronize a previously migrated install

Assumptions:

1. The script will detect automatically whether the current install to be migrated is a Wubi or normal install.
2. If you are running the script from a live CD/USB then the --root-disk= option is required. The grub2 bootloader must be installed when using this option. If there are separate virtual disks (e.g. usr.disk, home.disk), they must be in the same directory as the root.disk. (Grub-legacy not supported).
3. The grub2 bootloader will be installed to /dev/sdX where /dev/sdXY is the target partition, unless --no-bootloader is specified. You will still be prompted whether to install the grub bootloader unless option -y or --assume-yes is supplied.
4. If the install being migrated contains grub-legacy it will be replaced with Grub2 (only on the migrated install). You are not required to install the Grub2 bootloader, however, if you choose not to then you will have to manually modify the menu.lst to boot the migrated install. NOTE: the grub2 installation takes control and requires user input on releases 9.10 and greater. It will also prompt for the bootloader install drive/partition.
5. The target partition file system will be formatted as ext4 (default) or ext3 if detected on the install being migrated. The script will not modify the partition type i.e. set it to 83 (linux)
6. The script supports migrating from multiple partitions, and also to multiple partitions. Separate target partitions are supported for /boot, /usr and /home.
7. If the migration terminates due to a corrupted file, after fixing, rerun the script with the --resume option. This picks up from where it left off, potentially saving a lot of time. The target partitions must be the same as in the prior run.
8. The --synch option will resynchronize a migrated install. New or modified files will be synchronized with the migrated install. The target partitions must be the same as in the previous migration. CAUTION: files that have been added only on the target will be deleted.

Notes: If you install the grub bootloader, then the grub menu from your migrated install will be presented at boot - not the windows menu (for Wubi installs.) If you do not install the bootloader, then you will still be able to boot the migrated install from the current install's Grub menu, unless your current install uses grub legacy. For Wubi users, make sure you install bootloader before uninstalling Wubi.

To install the bootloader manually, boot your new installation and run: sudo grub-install /dev/sdX (where X is the drive you boot from e.g. /dev/sda)

Recommended: Run "sudo update-grub" on the migrated install after booting the first time
