If I partition my 120gb ssd and create 1 20gb partition for installing windows on it. Will setup still create the ESP/EFI partition needed for my machine (not talking about the MSR partition)?

Hello Pete,

Sorry, but no. To have all the UEFI partitions created, you'll need to clean install Windows on an unallocated disk instead.

My head is spinning. To be clear there can exist the following partitions. Not sure if WinRE will be created on a UEFI system for whatever reason.

Factory Recovery

AFAIK. WinRe, MSR are not needed. Recovery is not needed for my system as well.

How to avoid the WinRE and MSR?

If you use UEFI it will create a small, 128MB IIRC, partition at the root of the drive as this is needed for UEFI to work, Think of it as a type of MBR

If windows is installed onto a clean disk it will add the System Reserved partition, Size will depend on OS installed but Windows 7 defaults to 100MB

If you pre allocate your preferred partition scheme then Windows will install it's system files onto the partition you select for the Windows install as it always did. The potential issue here is that boot errors may bork the whole Install whereas the separate System Reserved partition is more robust and less likely to effect the actual windows install - this is of course your choice to make

The other partitions you mention are I think all either OEM recovery partitions or different naming conventions for parts of these and are imaged onto the disk by manufacturers, as stated above, I've seen up to four partitions involved in OEM recovery options on a single drive
