What are the best options that allow running a Linux distribution, such as Ubuntu inside Windows XP, i.e. within a window?
By "best" I mean quick startup time, low memory requirement, good graphical performance, easy access to the main (host) Windows XP file system.
I know about Wubi and standard Ubuntu with the dual boot capability, but I'd prefer to be able to switch from XP to Linux without a reboot. I know the Linux experience may not be ideal this way, but it would be pefectly good for my needs.
I've downloaded VirtualBox and the latest Ubuntu and will try the virtual machine approach; however are there any specifically customised Linux versions for this purpose?
I think this would be a great way for people new to Linux to get used to the OS while still having the "safety net" of Windows.
