I use dual boot Ubuntu 20.04 and Windows 10. I want to resize the windows partition (/dev/sda4) by shrink space from Ubuntu partition (/dev/sda1) and add this space to Windows

I boot gparted using USB and i can shrink space from ubuntu partition, but i can't use this unallocated space.

How i can move the Microsoft reserved partition , to increase windows partition space ?

Thanks

Delete and recreate it (with the same 'msftres' flag). This partition is nothing else than a 16 MiB space reservation – any data it contains is irrelevant.

  • the Microsoft Reserved Partition stores the Windows bootloader files. Windows will not boot if this partition is deleted

    It doesn't. They're stored in the "EFI System Partition" in your screenshot. (On BIOS systems, the bootloader files are stored in an NTFS partition of similar size to the EFI partition, whose NTFS label happens to say "System Reserved" while it has no relationship to the partition that you currently have.)

    The MSR partition is used with GPT to support software components that formerly used hidden sectors and technically doesn't need to exist, although Microsoft recommends it (many OEMs don't create it)
