I installed Ubuntu 12.04 LTS into Windows XP using Wubi.exe. Update Manager tells me an upgrade to 14.04 is available, and the Manager has an "Upgrade" button. If I click that, will it upgrade my wubi-installed Ubuntu in Windows and leave Windows intact, or will it install the upgrade on top of Windows, thereby, eliminating Windows? I want to keep things just as they are except have Ubuntu 14.04 LTS instead of 12.04 LTS. Would it be better for me to uninstall 12.04 and do a fresh install using Wubi.exe (14.04)?

The upgrade won't touch Windows. However, it will need plenty of free space - upwards of 3GB. So if you have the free space, go on ahead.

The upgrade does run an update-grub but it does not replace the main bootloader and maintains that configuration and such, though my recommendation is that you actually use sudo do-release-upgrade as I've had problems with the gui crashing and leaving the update running but not completely.

Do not upgrade your Ubuntu release if you installed it with WUBI. WUBI is only mean for testing Ubuntu on your PC. If you wish to fully use Ubuntu and make future upgrades in the future then please make a real install, make a partition destined only for ubuntu.
Repeat, do not atempt to upgrade your ubuntu release if you installed it with WUBI. WUBI is also no longer maintained.
