Windows won't recognize a partition unless you have the partition type
byte (Linux ignores this byte and just looks at the partition
content).  In guestfish you would have to do:

  part-set-mbr-id /dev/sda 1 0x7

That is for NTFS; use 0xb for VFAT.

For more information see:

https://github.com/libguestfs/libguestfs/blob/3893dc0b9436ebb4dd620c6ca9b1d038eacf83a6/tools/virt-make-fs#L438

Unfortunately at the moment there is no method of setting the UUID of
a GPT partitioned disk.
