Thanks for getting back to our community.
I understand you would like to perform BIOS recovery on your NUC model D54250WYK.
Please take a look at instructions for BIOS recovery available below:
BIOS recovery download file is WY0024.BIO
I have found self the solution to recover the bios to version 024 and is not the problem.
The question is this: Why don't work the last version 025 not correct.
I am glad you fixed your computer with BIOS version 024. I am sure Intel is aware of this problem and is currently working to get this matter fixed on next BIOS release.
