Windows 10: Blues screen when I connect a second bootable drive to my system

We use the Asus WS X299 SAGE/10G motherboard in a number of our products. We are releasing a new product that requires us to have two boot devices. Boot device 1 is the production system image and boot device 2 is a test image. The production system image boot device 1 is installed in the m.2_2 slot during system assembly. The test image boot device 2 is installed during product testing I have tried the m.2_1 slot as well as a SATA port. We would like to install boot device 2 during testing, then disconnect and boot into the production image after for final product configuration. The motherboard is installed in a custom chassis with custom PCIe cards and a custom fan kit. The mechanics of the Fan kit and PCIe cards make it nearly impossible to install the m.2_2 drive boot device 1/production image after testing as it would require significant disassembly and reassembly which would require retest.



I first tried installing boot device 2 in the m.2_1 slot while boot device 1 was installed in m.2_2 and found that the system blue screens when it tries to boot into windows. I then tried boot device 2 on a SATA drive and plugged into a SATA port. This had the same result. If I remove boot device 1 then the system will boot from boot device 2. It seems I can only have one or the other boot device installed. I have done this kind of thing on other motherboards in the past without a problem not Windows 10 though. Both boot devices have Windows 10 loaded. Is there a BIOS setting that needs to be changed for this to work?

Make second drive bootable

Thanks guys. The first drive is actually now in another computer. I was trying to cheat to make the drive that was the second drive bootable. I downloaded Partition Wizard Bootable CD and was able to make it the primary drive, but that still didn't work since it had installed BOOTMGR on the first drive. Secondly, I'm short one DVD drive ATM. I'll have a new DVD drive here on Friday and then I will try newtekie's suggestion, mostly out of curiosity. It has 32 bit on it now and I'm going to give 64 bit a try. Anyone have the RC1 64 bit ISO?

Make second drive bootable

Just stick the Win7 DVD in the drive and boot from it.

Push Next on the first screen. Then select "Repair Computer" on the second. It is down in the left corner, kind of hard to see.

It should then automatically do some repairs, then tell you to reboot.

Boot into the Win7 DVD again, and do the same, this time select "Startup Repair". Let it do its thing, and then you should be able to boot using the second drive.
