Since my computer can't handle an actual disc for some reason, I tried to use VirtualBox to run Ubuntu on Windows. However, I can't use 64-bit ISOs, because VirtualBox is 32-bit. Is there a 32-bit ISO for Ubuntu?
Yes, 32 bit images are still available for all Ubuntu and Ubuntu "flavour" releases. (Although not necessarily for other distros based on Ubuntu - for example KDE Neon is 64 bit only.)
They are a bit harder to find than I remember, though.
