Windows 2016 unattended installation throwing error "The selected disk space is not of type ESP" in UEFI mode

[Guest Bhupesh KM]

Hi all,

 

I'm trying to install Windows 2016/Win 10 on a server using boot.wim and Unattended file.

 

I have formatted the harddisk into two partitions, EFI partition with FAT32 and user partition with NTFS

 

I'm keeping the uefi files and boot.wim in the EFI partition and booting into it.

 

By editing the startnet.cmd inside boot.wim, I had added code to copy the contents of user partition to x:\temp and then restore back once i format the partition to ntfs again from winpe environment.

 

Finally i will be calling setup.exe present on the OS iso, with the unattended file present on user partition as argument.

 

My unattended file is having Install partition as 2, since user partition is 2.

 

When the installation is about to start copying files, I'm getting the error "The selected disk space is not of type ESP".

 

 

 

Thanks in advance,

 

Bhupesh
