I have an SSD with windows 10 (EFI). I want to install ubuntu into a second ssd to have a dual boot.

I really don't want to mixed them, that say that if i want to reset windows i just have to unplug my linux ssd, and replug it when the reset will be done. And everything have to be ok after that. Also that say that if i unplug one of the two ssd i can boot on the only one ssd without problem.

I want to know if the default ubuntu installation give me what i want or if i have to do something with the grub or something else to perform that thing.

Thanks.

If windows is installed in uefi, you have to boot your ubuntu installation in uefi too. During installation you have to manually allocate your partitions, that is to says :

  • Create a partition for efi (250MB)
  • Create a partition for swap (2xRAM)
  • Create an EXT4 partition (disk space remainder)

After the installation your computer will still boot first to your windows, so you will not have access to grub. To change that, change the boot order in your bios and make ubuntu uefi in first position. You should have access to grub and you will be able to choose what launch between windows and ubuntu.
