Hello friend, recently I installed the Ubuntu operating system and now I want to install the gentoo OS on this system. If anyone knows the exact step by step process then please inform me. I want to install this Gentoo software on the system. I hope someone have reply about this post. I've already installed the iso image onto my usb drive. After that I did the booted up task from my usb drive. Then it loaded but when I turned off the computer and removed the usb it reverted back to ubuntu. Can anyone help me to install gentoo?
