Howdy! Welcome to the LUG.
It sounds like you've already got a good grasp of Linux if you are running dual-boot with 8/Ubuntu.
I'm sure you've already run into this:Linux and Windows 8: Fast Startup puts data at risk
The new Fast Startup feature of Windows 8 puts the filesystem's integrity at risk if other operating systems are used to write to Windows partitions. Data loss is particularly likely with dual-boot configurations that involve Linux and Windows 8.
To avoid data loss and filesystem inconsistencies, users who run Windows 8 and Linux on the same computer should disable the Fast Startup feature that was introduced with Windows 8 and is active by default. The Fast Startup feature creates an issue because it doesn't shut Windows 8 down completely but switches it to a special hibernation state instead – although it looks like it has been freshly booted when switched back on because all applications have been closed. However, for the Fast Startup feature's hibernation state, Windows 8 will store Windows session information – such as the cache with the current filesystem state of any mounted FAT and NTFS partitions – in a memory image that is restored during Fast Startup.
You'll have to bring it by the next ALUG meeting and give us a quick demo, if possible.
