Windows 10 is installing system reserved on secondary hard drive

My friend has an ultrabook that was giving him issues. I decided to do a clean install of Windows 10 with the Creators Update ISO.

This computer has a 750GB HDD and a 24GB mSATA drive. The computer originally came with Windows 8 and the mSATA was a cache drive ... and was updated to Windows 10 during the free period.

I've installed Windows 10 twice now, and both times it installs a 500MB "System Reserved" partition on the mSATA drive instead the HDD.

How do I prevent this? Normally I'd just pull the mSATA, install Windows, then put it back in, but I looked up disassembly instructions and more than I'd like to do, as I said it's an ultrabook so it's not very easy to take apart.

Any suggestions?

Thanks.

If you can't physically remove the secondary drive, disable it in the BIOS until you are done installing Windows and then go back and enable it again.

No it shouldn't ,this would just give the intermediate user more chance to mess things up.
The advanced user can use the console on the installation media to prep his drives any way he likes.

That is a valid option too, but only if it installs everything just on the designated drive (the drive you select to install Windows on it).

Putting boot files on a second drive, that might not even be kept in that system, has much more chances to mess things up than asking the user during install.
