How to Use LVPM to copy Wubi-Ubuntu Desktop to a VPC Partition

Wubi is the abbreviation of WindowsUbuntu-BasedInstaller, that is, virtual disk space in windows partition (NTFS), as a loop partition independent of windows, as the linux root directory /. Using LVPM (LoopmountedVirtualPartitionManager) can expand the space of a virtual disk (using the resize function of LVMP), or copy the linux system from a virtual disk to a real shard.

Wubi is short for Windows Ubuntu-Based Installer, that is, virtual disk space in windows partition (NTFS), as a loop partition independent of windows, as the linux root directory /.

You can use LVPM (Loopmounted Virtual Partition Manager) to expand the space of a Virtual disk (using the resize function of LVMP), or copy a linux system from a Virtual disk to a real Partition, implement a real windows + linux dual-system.

1. Partition

In wubi-Ubuntu, we recommend that you split the blank partitions into SWAP partitions (SWAP) in linux using the system's built-in Disk Utility. The remaining partitions are linux partitions (ext2, ext3 or ext4 format ).

Below is the data after the disk partition

Administrator @ ubuntu :~ $ Sudo fdisk-l

[Sudo] password for administrator: Disk/dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065*512 = 8225280 bytes Sector size (logical/physical): 512 bytes/512 bytes I/O size (minimum/optimal): 512 bytes/512 bytes 

 Disk identifier: 0x00000001 

Device Boot Start End Blocks Id System

 /Dev/sda1*1 1275 10241406 7 HPFS/NTFS

 /Dev/sda2 1276 1397 979965 82 Linux swap/Solaris

 /Dev/sda31398 6123 37961595 83 Linux

 /Dev/sda46124 38913 263385675 f W95 Ext 'd (LBA)

 /Dev/sda56124 16723 85144468 + 7 HPFS/NTFS

 /Dev/sda616724 27738 88477956 B W95 FAT32

 /Dev/sda727739 38913 89763156 7 HPFS/NTFS

 From the data above, we can see that the primary partition starts from/dev/sda1 and the extended partition starts from/dev/sda4. The first extended partition is/dev/sda5. let's look at the partition capacity.

Administrator @ ubuntu :~ $ Df-lh

File System capacity in use available % mount point

/Dev/sda3 36g 4.1G 30G 12%/

None 999 M 328 K 999 M 1%/dev

None 1004 M 348 K 1004 M 1%/dev/shm

None 1004 M 92 K 1004 M 1%/var/run

None 1004 M 0 1004 M 0%/var/lock

/Dev/sda1 9.8G 4.6G 5.3G 47%/media/SYS

/Dev/sda5 82G 75G 7.1G 92%/media/SOFT

/Dev/sda6 85G 75G 9.9G 89%/media/WORK

/Dev/sda7 86G 81G 4.9G 95%/media/BACK

The UUID of the partition (universal Unique Identifier is the Unique Identifier) should also be known.

Administrator @ ubuntu :~ $ Ls-al/dev/disk/by-uuid

Total 0 drwxr-xr-x 2 root 160.

Drwxr-xr-x 6 root 120 ..

Lrwxrwxrwx 1 root 10 2011-04-22 15fbe968-a73a-4b14-8315-ae841cf0d048->.../sda3

Lrwxrwxrwx 1 root 10 237D-1AF7->.../sda6

Lrwxrwxrwx 1 root 10>.../sda2lrwxrwxrwx 1 root 10 9AC4BB30C4BB0D8F-> ../sda7

Lrwxrwxrwx 1 root 10 D028BF0728BEEB9A->.../sda5

Lrwxrwxrwx 1 root 10 DE305BE6305BC3E5->.../sda1

2. Use the transfer function of the LVMP tool.

In this step, LVMP does three things: format the target partition into the ext4 format, copy the file, and install and copy grub.

 In this step, you should note that you should change the uuid and path of the partition to the target partition (that is, the red part ). Because LVPM did not change the partition and path when copying grub.

 

You also need to modify menu. lst under \ boot \ grub.

Timeout = 5
