How to install Ubuntu on second Hdd without affecting Windows 10? no dual boot and no boot up menu. I simply would like this as my set up windows 10 is on my main HDD 2tb drive is sata 1 I would like my pc to always boot directly into windows with no boot up menu like grub for example just straight into windows with ubuntu on my second HDD installed apart from windows where the only way to boot ubuntu is to go into the bios and select the boot medium as the drive with ubuntu on it otherwise the computer should display no signs of having ubuntu installed on it the only other hdd drive on the machine is a WD 320gb in sata 2 this is where i want to install ubuntu but nearly all i have tried so far ends up with a menu when i press the power but asking me wether to start windows or ubuntu this is the complete opposite of what i want i just want an ubuntu backup drive i can access when windows 10 shits out on me which it does frequently thank you microsoft for that but as you imagine im growing more and more infuriated by the fact that everything i have researched has had the same problem it ends in a dual boot scenario when all i am aiming for is a backup drive i can find no helpful information on this topic anywhere else on the internet that actually works except for "its possible, it can be done" and before its mentioned please no answers that would change or damage the windows 10 system in some manner i want the windows 10 disk to stay untouched in the matter
