How does Wubi works (Linux under Windows)?

[frenchn00b]

Wubi is easy way for getting linux running with dualbooting; but

Where does the ext3 is installed ?? into the ntfs without partitions we all know that linux cannot write in ntfs (copyrights) ? captive? then it may be risky for the data?

[meborc]

as long as i remember, ubuntu system will be installed all into one file in ntfs... like virtualbox hard-drives...

anyone care to comment/correct?

How does Wubi work?

Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the Windows file system (c:\ubuntu\disks\root.disk), this file is seen by Linux as a real hard disk.

Basically the ext3 filesystem is put into a single file on a hard disk (like a virtualbox/vmware hard disk) but unlike vmware Wubi lets you boot directly into it.

but the linux cannot write into NTFS ... hence there is need to put the data on a usb stick ?

When booting i dont think Wubi actually does much with NTFS. It picks up the ext3 partition file and boots directly into the ext3, all of which is handled by the boot loader, which means Ubuntu doesnt really have to touch it.

Disclaimer: I havent used Wubi, doubt i ever will, so i dont *really* know what im talking about, this is just how i understand it works from reading some FAQs

If you use irc you might want to talk to 'xivulon' on freenode as he seems to be the main developer.

That's how I would think it is. You're basically booting a file that has an EXT3 file system inside of it.
