Windows 10: [INSTALLATION] System partition only takes up 100mb for Win10?

Trying to Re-install windows on my PC via USB https://www.microsoft.com/en-us/software-download/windows10, When creating the partitions the reserved system one that automatically is created only takes up 100 Mb for some reason, even though Win10 is supposed to have a 500 Mb reserved partition.

The Extend option is grayed out and I cannot use it. Got any idea what's going on/how to fix this issue?

Question about Win10 and partitions.



So I have a partition ready for Win10 but my question is will I still be able to access my other partitions once Win10 is installed? I keep hearing about the "recovery partition won't be able to be used" and I'm wondering if Win10 just doesn't play nice or if I'm good to go.

 

Recovery Partition vs System Reserved Partition

Thanks for all the info guys.

Both original & target SSD's are listed as MBR as opposed to UEFI. I may have created a partition unknowingly in getting the original/new unformatted drive recognized, but I don't recall taking any steps that Windows did not step me through.

Not that an upgrade to WIN 10 Pro is contemplated, but I suspect that having no System Reserved partition will not allow that to happen, after seeing how the original WIN 10 upgrade created a problem for some WIN 7 users that had a smaller 100mb vs 500mb System Reserved partition.

 

The Efi system partition deleting during clean install....

Hello,

I have the Dell inspiron 15 5558 and i wanted to know that mine got a partition called the "EFI system partition" which is of 100mb. So, when i will go to clean install of windows 10 to the step to delete all my partitions, will that system reserved partition
be recreated during install? Or i have to click on new, and then that system reserved partition gets created(which will be of 500mb for windows10 according to my research)?
