I just bought the prettiest desktop there ever was and I'm having |
| 2 |
trouble with the install. I'm quite comfortable with a BIOS setup, but |
| 3 |
UEFI is still making my brain hurt and Windows 10 co-existing on the |
| 4 |
machine isn't helping. |
| 5 |
|
| 6 |
Basically, I can't find where to tell Grub and everything else to look |
| 7 |
for boot stuff. On my laptop (Surface Pro), the machine came |
| 8 |
partitioned (by Windows 8) to have an "EFI system partition". So the |
| 9 |
output of `parted` on my laptop looks like this: |

However, my new desktop came pre-installed with Windows 10 and there's |
| 27 |
no EFI system partition on either of the drives: |

Note that all I did to the partitioning scheme above was: |
| 68 |
|
| 69 |
* Shrink partition #3 on the first disk and create a new one in the |
| 70 |
vaccuum (ext4) for Gentoo |
| 71 |
* Delete partition #2 on the second disk (it was empty ntfs) and replace |
| 72 |
it with one big ext4. |
| 73 |
|
| 74 |
So what do I tell grub and the kernel to use for boot information? The |
| 75 |
handbook mentioned that there were differences between gpt and msdos |
| 76 |
partition setups, but the machine came this way, setup with msdos on the |
| 77 |
first disk and I'd rather not blow away all 300GB of Windows on a |
| 78 |
hunch. Do any of you have experience with this? Some guidance here |
| 79 |
would be super. |
