Error 0xc1900200 for update W10 CU, partition EFI is the problem

[dickfrey]

Hi, i have tried for two weeks to upgrade W10 to Creators Update.

Everytime i get the 0xc1900200 error, that is very generic (There is a problem...).

Inside a log i think i have identified the problem : it requires 15 MB of free space inside the EFI partition (only 100 MB), but there are only 9 MB free.

Inside that partition there is a mix of files between HP and Microsoft (Bios, boot, ecc...).

So i have two ways :

1) delete something inside that partition, to arrive to 15 MB of free space... but what ?

2) merge the partition with free space, but the free space isn't near the EFI partition, and it can merge the two.

Another strange thing : why from W10 (disk management) i don't see the 16 MB partition (that between EFI and C), but only in minitool partition wizard ?

Can someone help me ?

Thanks

Because partitioning was difficult and dangerous for data, this is the solution :

I followed the GPT guide.

I have deleted all the languages, except English and Italian.

Then, inside Font, i have deleted the Chinese and Korean fonts.

I obtained 19 MB free, so the Creators Update worked.

Definitive solution. All resolved.
