My wife has been using Windows Vista on her computer, and it has finally borked bad enough that she is willing to try Ubuntu. The system is pretty much unbootable as far as I can tell, and I need to download and burn an ISO image of the 64-bit version of Oneiric Ocelot (11.10) for her. Can I do this from my 32-bit machine?
The bit version of the CD or DVD does not matter where you burn it. You can even burn a PC version of the 32 Bit or 64 Bit on a Mac. Same for windows and same if you are burning a 32 bit on a 64 Bit PC or vice versa.
What does matter is if you want to run it afterwards. Is it recommended to download the 64 Bit version if you have a lot of ram and the whole architecture is 64 Bit ONLY. This changes if it is one of those 32 Bit and 64 Bit architectures that support both.
It is also not necessary to run a 64 Bit on a PC that supports both, 32 Bit and 64 Bit but has 4GB or less of ram. The performance will not be any better if you use the 64 Bit. Stick with the 32 Bit for more compatibility in that case.
So in any case, don't worry about where you burn what type of CD/DVD.
