I have a Packard Bell ENTE69CX laptop and it has only 1 hard drive slot, and because I want to buy SSD and I didn't used CD-ROM in like 2 centuries, I bought a case that replaces CD-ROM with HDD slot. So I placed my drive in it, but no matter what boot option settings I set, it says that there is no bootable drive. I even plugged USB with Windows 10 on it, and it detects this drive perfectly when choosing where to install Windows 10. Any ideas what to do in order to boot from this drive?
