Advantages and Disadvantages of WUBI

For me this is something new that you can install a whole operating system under another operating system considering it as a native application. You can install or uninstall it anytime without worry as it almost removes chances of anykind of data loss.

Advantages of WUBI{Windows-based UBuntu Installer}

1. Wubi doesn't need a separate partition rather it install in existing drive's free space

2. You have minimum{negligible} risk of any data loss

3. WUBI doesn't override window's boot menu .

4. Good backup or restoration i.e. wubi creates a single file for it's / {root} partition, this file is saved as root.disk. To save this file go to directory where ubuntu is installed ..Search for root.disk.This is your whole / {root} partition.. keep this for future failures or restoration.... you can copy this whole file to any folder and replacing it will restore all your / partition at any time...

Disadvantages of WUBI

1. If you have large sized root.disk then it is hard to make a copy

2. Hibernation is not supported

3. File system is more vulnerable to hard reboots

4. If the Windows drive is unmounted uncleanly (most commonly because of a Windows crash and force shutdown), Ubuntu will not be able to mount the Windows drive and boot until Windows has successfully booted and shut down. If the Windows system cannot be booted after the crash, the user also cannot boot Ubuntu.

5. Performance related to hard-disk access is also slightly slower, more so if the disk image file is fragmented as it is a frequent problem in windows.
