Root Dual Boot CyanogenMod7 sd card issue

[cigarjockey]

Noob having issues here..
Used this video to dual boot my NC.
Got CM7 on the Nook yet my 8 gig card now show only 30mb available.
Can I take the sd card out and undo the Partition part they covered?
Don't want to brick it.

Wow, can't take more than a couple minutes of those goof balls.

Sorry, but I prefer my instructions in writing, not from a video. I get nothing out of that.

Power down your NC. Take your card out and insert it in your computer. Open disk manager (under administrative tools in control panel OR right-click on my computer and choose manage). Find your sd card and see if you can delete the last partition (right-click on it and choose delete) and create a new one using all the available space, then format it as FAT32.

If that doesn't work, then you can use these directions to delete that last partition: Partition or Volume - Delete - Windows 7 Forums

You SHOULD have done that before you installed a rom on it so you don't lose anything.
