    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)?

    Can I delete My 16MB Reserved Partition to Increase My EFI Partition

    Hi All,

    I want to increase my EFI Partition from 100MB to around 1GB so I can install Windows 11.

    It is on an SSD which is 500GB.

    However I have been unable to come up with a way to do so due to a 16MB system reserved partition in the way that I dont know what it does. Can I delete this system reserved partition show in the attached image without any risk so I can shrink my C Partition to then give space to the EFI Partition?

    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.
