Hi,

I bought a cheepo Chinese dual boot tablet a while ago.
It has windows 10 installed on a 18.4 Gb partition with currently 4.5 Gb free. (32 bit os)
It installed the anniversary update last year without a problem. (no manual intervention required)
This years creators update has not installed yet but that's (probably) because it is not yet available here (my win 10 pc with large disk has not gotten the creators update either).

Just to illustrate that it can be done on a 18 GB partition, so 25 GB should also work I guess (unless maybe you have 64 bit os ???)

I read that there is something in Win 10 that is called Compact OS, which will have Win10 use some system files compacted and save you disk space.

To check if your windows is running compact or not and other information about the subject see the link below

Hope this helps . . .
