Are you a Windows user wanting to test/use Linux without having to worry about partitions, bootloaders and other incomprehensible concepts? What if you could just install Linux as if it was a common Windows application? What if you could remove it whenever you want to? Don’t want to burn a CD? Sure.. I, for one, welcome our new Ubuntu installer overlord, Wubi!
Wubi comes in a simple .exe file which installs Ubuntu Linux into a Windows folder, hence it doesn’t need any partition magic. No wandering around with MBR is needed since Wubi uses the Windows bootloader (believe me, it’s there!) adding an entry to the Linux system and so making the install more secure for your existing data.
Get it, install it, be happy! 😀
