Can't install Windows 10 UEFI next to MacOS High Sierra on same SSD

No need to select a volume to format a partition. Format operates on the selected partition, not a selected volume.

If I write

format

The output I get is

No volume is selected

Even if I had selected the disk and partition I want to format using select disk and select partition.

I've never had an issue just formatting within the Windows installer.
I'm not really clear on exactly what you're doing.

Hey @uchika96, did you solve it? I have the same issue.

Hello sir, I have the same problem. I tried many times but getting error like in my attachment.

Strange thing is, when I select Unallocated space to install Windows and click next, it seems to create it's own additional partitions (including 100 mb partition). I guess it can't detect EFI partition of the macOS.

I am pretty sure that it is GPT and windows setup is also in UEFI mode.

Confirming HDD+SSD attached led to error. Disconnected HDD and Windows Instalation succeeded.
