I'm brand new to Linux/Ubuntu, and I have multiple flash drives with the latest release on it. Last night, I mistakenly installed the 32-bit OS while I intended to install the 64 bit. Just before doing so, I took an image of Windows 7 64 in case something went wrong.
I want to upgrade to 64 bit version of Ubuntu while keeping W7 64. Is there a way for me to easily do this? If I use my 64 bit live disk, will the 64 bit version overwrite the 32 bit?
Alternatively, could I just recover the PC from the image I took before installing Ubuntu, wiping everything clean INCLUDING 32-bit Ubuntu (then install 64)? Or will the W7 recovery ignore Ubuntu all together?
