bios selection

[mels_101]

Hi all

have couple of devices on legency bios and some on uefi. On the task sequence how does it pick what one to use for the required model.

thanks

If UEFI is enabled in the BIOS then it will build UEFI. If it's legacy then it's legacy! Simple as that.

The result of this is that you may need to look in to using BIOS tools to automate the BIOS changes. We're going to wait till 1703 is deployed as that has non destructive tools to convert to UEFI (MBR2GPT).

Thanks for your reply, was hoping it would work like that, wasn’t sure if you had to add a wmi query in.

What partitions do you need in the uefi TS? And what ones are set as boot drive with no drive letter.

recovery - 400mb (no drive letter and not boot drive)

efi - 350mb (no drive letter and boot drive)

msr - 16mb (no drive letter and not boot drive)

primary os - 100% remaining. (Drive letter assigned and no boot drive)

is he above correct? For Windows 10.

thanks

If you do a new test task sequence - build and capture - it will add the BIOS and UEFI partitioning automatically - so just copy the steps from that.

Yes it works Win 10 .

I would also add the TS variable OSDPreserveDriveLetter = false  after the Partition UEFI step otherwise you may not get letter C: allocated to the disk

Do you need the msr and recovery partitions? 

Thanks
