I just bought the prettiest desktop there ever was and I'm having trouble with the install. I'm quite comfortable with a BIOS setup, but UEFI is still making my brain hurt and Windows 10 co-existing on the machine isn't helping.
Basically, I can't find where to tell Grub and everything else to look for boot stuff. On my laptop (Surface Pro), the machine came partitioned (by Windows 8) to have an "EFI system partition". So the output of `parted` on my laptop looks like this: Number Start End Size File system Name Flags 1 1049kB 379MB 377MB ntfs Basic data partition hidden, diag 2 379MB 588MB 210MB fat32 EFI system partition boot, esp 3 588MB 722MB 134MB Microsoft reserved partition msftres 4 722MB 53.2GB 52.4GB Basic data partition msftdata 5 53.2GB 256GB 203GB ext4 6 256GB 256GB 16.1MB However, my new desktop came pre-installed with Windows 10 and there's no EFI system partition on either of the drives: # parted /dev/nvme0n1 GNU Parted 3.2 Using /dev/nvme0n1 Welcome to GNU Parted!

So what do I tell grub and the kernel to use for boot information? The handbook mentioned that there were differences between gpt and msdos partition setups, but the machine came this way, setup with msdos on the first disk and I'd rather not blow away all 300GB of Windows on a hunch. Do any of you have experience with this? Some guidance here would be super.
