Q: rename efi boot windows 10 bootcamp os x imac

Hi Loner T,

Thank you for your reply. I thought I should describe what I did, should it help someone out there.

I had been trying to install Bootcamp W10 on a 2012 Retina Macbook Pro running El Capitan. I used a 160gb HDD to attempt to install windows 10 and after bootcamp installation loaded and the mac restarted, I was left with a black screen.

Seeing that there was no way to go about using bootcamp to install it, I merged the partition and re-partitioned an unformatted empty space using command line. I proceeded to install windows via EFI Boot. I managed to install windows but everytime I selected the boot option, it would appear as "EFI Boot" instead of "Windows". The Bootcamp drivers on Windows did not work properly too.

The main reason why bootcamp installation did not work for me was because I was using an external harddrive instead of a flash drive. I believe the Mac has issues booting into the EHD after the Bootcamp installation restarts. (Saw this on another thread, thanks again Loner T!) Everything worked smoothly once I got my hands on a flash drive.

With regards to this thread, I did not manage to rename the initial EFI Boot partition.

If you have devices driver issues, on the specific model, EFI boot does not work well. Audio and GPU would be the main issues. I installed W10 2 days ago on a 2012 13-in MBP, in BIOS Mode, and audio works properly as noted in Re: bootcamp no sound win 10.
