The Dell model Precision M3800 has a SSD disk configured as a second harddisk, disk 1. Disk 0 is a magnetic drive.
Problem in SCCM2012 is that I was unabel to find a fast solution for the fact that partitioning didn`t went well in the task sequence. I got different results with different configurations but no disk 0 with a driver letter D and a disk 1 with a drive letter C.
I wrote this diskpart script to partition the drive en format the Dell Precision M3800. It will format both drivers, only for first install`s.
rem ++++ change the bootmedia driver letter select vol c assign letter=g select vol d assign letter=h rem ++++ Format SSD drive 1 select disk 1 clean convert gpt rem ++ Par 1 create partition primary size=300 format quick fs=ntfs label="Windows RE tools" set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac" gpt attributes=0x8000000000000001 rem ++ Par 2 create partition efi size=100 format quick fs=fat32 label="System" rem ++ Par 3 create partition msr size=128 rem ++ Par 4 create partition primary format quick fs=ntfs label="Windows" assign letter="C" rem ++++ Format Magnetic drive 0 select disk 0 clean create partition primary format quick fs=ntfs label="Storage" assign letter="D" exit
Create a package with the txt file and run it with diskpart.
The USB ethernet USB-dongle delivered with the notebook should be able to work with PXE. Non the less I wass able to boot only once in 20 try`s in different setups from PXE in UEFI mode.
It does work better in legacy BIOS mode, but in UEFI mode it doesn`t.
