NVME BOOT UEFITOOL WINDOWS

This should help anyone who is stuck in MBR in UEFI.ġ) Make sure you have your data/windows partition backed up to another drive (in my case, it was my original SATA drive).Ģ) Boot to recovery media, go to command lineģ) Use DISKPART to Clean the drive, then Convert GPTĤ) I then followed the steps here. My error was trying to convert the drive to GPT after cloning the drive. You can indeed use an NVME drive on a PCIE adapter on a Z87 board after the AMT BIOS hack. I can’t run any other boot recovery tools because I think the UEFI/MBR combo confuses the heck out of them.Ĭlick to expand.I got it working, if anyone is in the same boat. The only boot scenarios that now work are 1) recovery flash drives, or 2) the SATA drive as primary and the NVME drive as boot (see images). If I try to boot into BIOS I get MBR errors. However, things went awry and even on my old Samsung SATA drive, I now have MBR that only boots in UEFI.

Then I ran the “fix windows boot problems” as instructed in their walkthrough as the last step. So I followed the instructions on Macrium’s support page to boot on their recovery Media, then clone the drive, and then convert to GPT, then add the additional partitions needed for UEFI. I’m on a Z87 board so I did the AMBIOS hack to add the UEFI boot module. I wanted to clone to a new NVME drive, the Samsung 2TB seen in the images. I was on the 500mg Samsung SSD over SATA and I’m pretty sure it was BIOS/MBR.
