I have successfully installed Windows 10 on a 3-disk (hardware) RAID 0 setup, in a 150GB NTFS partition. As part of that, and because I booted my installation media in UEFI mode, the Windows installer created an EFI partition. The disks in the raid group all have a GPT partition table. I'm attempting to install Fedora 23 (in UEFI mode) in order to dual boot.
In following various guides, it looks like all I need to do is mount the existing EFI System Partition (created by Windows) at
/boot/efi, create my other partitions as desired, and everything should work.
Unfortunately, it doesn't look like the F23 installer is recognizing the EFI partition created by Windows as a valid option. When hitting
DONE to apply my partition changes, I get an "Error checking storage configuration". Clicking the link for more details reads as such:
No valid boot loader target device found. See below for details. For a UEFI installation, you must include an EFI System Partition on a GPT-formatted disk, mounted at /boot/efi.
However, the disk meets those requirements. The relevant output of
sudo parted -l reads:
$ sudo parted -l Partition Table: gpt Number Start End Size File system Name Flags 2 473MB 578MB 105MB fat32 EFI system partition boot, esp
I have disabled Windows' "fast boot" via the Power Management control panel.
Any help or pointers in the right direction would be greatly appreciated; I'm tired of programming on my old, slow laptop and would love to utilize my desktop's resources.
After reading through this bug report this morning, I think I may have found my issue. When installing Windows 10, it creates a 450MB "recovery partition" containing WinRE, the Windows Recovery Environment -- this is the first partition on the RAID0 volume, the ESP is second. I've got to go into the office now, but will update this post if I find a resolution tonight.
Specifically, I believe comment #59 on that issue may be the solution I'm looking for.
