Thank you for joining the Intel communities.
I’m sorry for the delay to come around to this post.
Please access the BIOS, press F9 on your keyboard to set the BIOS to defaults.
Now click advance and select boot, once your there, uncheck UEFI and make sure legacy boot is enabled or checked.
Then click devices and under USB you will see an option that it says xHCI set that option as disabled so you can use keyboard and mouse when you’re installing Windows 7.
Under the SATA option make sure the chipset SATA is checked and chipset SATA mode needs to be set as AHCI and press F10 on your keyboard to save the changes, now go ahead and see if you can install the Windows 7.after the operating system is installed go ahead and install all of the drivers and you can go back to the BIOS a enable xHCI mode.
Meanwhile I have given back my NUC for "repair". I will tell them now the advice you gave me for the BIOS configuration. Thanks.
I’m sorry for the inconvenience about this and please let me know if your unit works better after you send it for repair or if the recommendations I gave you work for you.
Thanks and regards!
Meanwhile I got my 5i5 back. They did not repair it at all, my fault, because I had covered the ID for a clean black look of the NUC. But this was no problem at all because it was the BIOS as some had hinted:
I went back to 0249 and started 1511 anew on a new Crucial M.2 SSD. Strangely it still gave the Partition error but fortunately only for a split second and then installed 1511 without any problems.
And this time the new graphics drivers worked for my standard high resolution monitor, a Dell U2713HMt. At least for the first few days.
What was the original SSD drive? Samsung?
The original drive was also a Crucial MX200 250GB CT250MX200SSD4.
