The storage partition exists, but it's ext4 formatted which means Windows cannot "see" the partition (because Windows doesn't support ext4). You can see the partition on any Linux OS.
Boot LE, enable SSH, login using WinSCP and copy the advancedsettings.xml file, or use PuTTY and copy/paste (might be easier and avoids the temptation of Windows users to create incompatible line-ending files in Notepad.exe).
