The partitions on the disk selected for installation are not in the recommended order
- I also got the same alert/prompt while installing Windows 7 on a GPT disk, to make it a dual boot with pre-installed Windows 8 (on a laptop with single internal disk), but I went ahead because all the things were in right order and I realized the equation can never be satisfied while making a dual boot on a single GPT disk with no problems ever.
- The ideal/recommended order is mentioned here - let's see what it says:
- If you make the GPT disk unallocated & then proceed with the installation, you will end with this structure:
- But preferably, you should plan this structure to make the Recovery easier:
- The Recommended structure requires some extra steps and is followed in OEM Laptops
- One will not be able to satisfy the equation for a dual boot ever on the same internal disk (see above) because a data partition should come in between the main Windows partition & Recovery Image partition. When you attempt to make a dual boot, you are planning two adjacent windows partitions, which will each look to the other as data partitions. The previously installed OS satisfies the equation, but the latter installed OS has a data partition placed before it, and I think that's the problem.
- There's a separate link for Win 10, but I think there is a mistake within the link and image:
- It seems wrong because it puts Recovery partition (WinRE) after Windows partition & doesn't mention Recovery Image partition at all!
- The WinRE tools partition which comes at the first place in Win 7/8 GPT config share same Type ID:
de94bba4-06d1-4d40-a16a-bfd50179d6ac with the Recovery partition that comes after Windows in the Win 10 GPT config as per the text of the links.
- How we can we confirm the mistake? I have OEM laptops shipped with win 7/8 with GPT. They came originally configured as per the link for Win7 /8.
But... I have never come across an OEM laptop shipped with win 10 with GPT with original OEM config. Do you have one?
- The Win 10 GPT config link also says about the partition order (leaving Recovery & Recovery Image Partition) that the non-Windows managed utility partition(s) should follow EFI & MSR partitions & Windows, with Data partition(s) following thereafter.
-
Partition Order: EFI, MSR, Non-Windows managed utility, Windows, Data
- I think it should be exactly followed in the Win 7/8 GPT config as well.
- It also seems obvious that Recovery Image Partition, if any, should serve as the last Partition on the disk, after Data Partition(s). So, where the Recovery (WinRE Tools) Partition in Win 10 GPT Config?
