Can the size of Microsoft Reserved (MSR) Partition be changed? RRS feed

  • Question

  • Per the Microsoft technet, the size of an MSR is 128 MB. But Mircosoft doesn't tell us if the size can be changed.

    I have a question, does it still work well if create the MSR Partition with 200MB or 300MB+?

  • Yes you can change it and make it as big as you want, just that once created- windows will not mount it by default so you can't see it.

  • Why do want to do that? 128 MB is a sufficient size at first place,  here is how you can do it,

    create partition msr size=1000

  • As efi and system partitotn can have larger size. Just want to know the 128M is the minimum size or changeless size for 16G+ hard disk.

    Per the command "create partition msr size=1000", it looks like the msr partition can be assigned more space?
