Today i finally got my new computer, so i decided to install Windows 10 on the SSD and it works without a problem. So next plugged in my older 2TB seagate HDD, just to see if the format of the drive was correct (i mentioned this in another post here) and it let me format the drive in question so i had all the room i originally had on the drive. But when i placed it on the mounting bracket and loaded into windows it said something about needing to remove a drive because an operating system couldn't be found, yet prior to this it was working fine lol. So i unplugged the HDD and windows booted. How can i make Windows recognise this HDD? Because it let me put programs etc on the HDD. Did i ruin the boot order plugging it in? Also, can i use this HDD i have mentioned just to install programs and my pictures etc? As i want my SDD leaving for games and Windows only. Thanks.
