My sister has one Laptop with Windows 10 version 1803 installed. I need some clarification on the partition this laptop has.
I can see 3 partitions in disk management. The first is the OEM partition. It is has a 529MB capacity, with 75MB free. It has no drive letter, but it does have a label/name. The second partition listed is the EFI partition. It has a capacity of 100MB with 100MB free space. Is this normal and preferred?
I don’t understand why it’s 100MB, seems kind of arbitrary, but I understand that 100MB is kind of the standard. I am not able to understand how EFI partitions are used, either. I was thinking were just there for boot purposes, so 100MB seems large. Anyway, are there any recommendations for modifying the EFI partition for Windows 10?

Hi @TimCook,
I would suggest to install your Windows 10 OS again in your laptop. I assume you have not yet configured your laptop so is your best time to resolve this issue by reformatting your OS.
Please follow the below steps:
-
press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
-
diskpart <-- start the windows command line partition management tool
-
list disk <— list the installed hdds in this computer for the next step
-
select disk 0 <- might have to replace 0 with the number of the correct disk
-
clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
-
create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
-
exit, exit to exit disk part and the command prompt
-
click refresh in partition manager and select your newly created partition and install to that
I hope the above steps help you to solve the problem.
Hello @TimCook
Would you please share the screen shot of disk management console, for that you will have to run diskmgmt.msc in run menu
So I can easily give you right solution
