I am currently using Mint 17.1 on a machine having both legacy BIOS and UEFI. Secure Boot is off. Mint is running on a fully encrypted physical partition and with swap partition is encrypted too. There is a 2 GB unencrypted /boot partition.
I wanted to know if there's a way I can install Ubuntu without creating a bootable CD or USB disk. Earlier in windows there was a way to download and install Ubuntu from windows interface. Can same be done here?
