Is it possible to remove the esp and the msr partitions on an uefi machine like how one would remove the "system reserved" 100mb partition on bios based systems?
And why are you trying to remove 100MB EFI System Partition (ESP) and the 128MB Microsoft Reserved partition (MSR)? when both use negligible space as compared to large bootable partitions? Although you can but seriously not recommened in any way. Here is what you can do to delete those: delete partition [noerr] [override] Use the delete partition command to delete the current in-focus partition. extend [size=n][noerr] Use the extend command to cause the current in-focus volume to be extended into contiguous unallocated space.
it's just a "what-if?" kind of question. I'm not going to really do it, and am aware of those delete commands, but I'm wondering what would happen if you remove them. On bios based systems, nothing happens. But on uefi systems, I heard something different happens, ie not booting.
