Question New PC build, "Reboot and select proper boot device" error

[Hammeryamz]

I just finished my first PC build and when I went to turn on the PC i got the "Reboot select proper boot device" error.

I am using the HDD from my last computer which is recognized in the BIOS (the HDD has windows 10 installed to it). I made sure that the boot order is correct, and i have tried changing the "legacy + UEFI" option to just UEFI and back again. Nothing seems to be working. Anyone know what is going on or how to help?

The old system was an older i5 dell computer, i can provide more information on it if that would help. tAlso, the hdd is a 2TB.

I just fixed the same issue with a secondary system, dunno how attached you are to whatevers on that HDD but a clean wipe and re-installation of my OS fixed those issues and removed the boot error for me

To clarify a bit I was informed of hardware compatibility issues with drivers/software from the old motherboard/chip conflicting with the new hardware, clean installing remedied that for me

I can't lose the info that is on that hdd. i have tried booting from an ISO of win10 on a flash drive to see if there is any possible way to get the hdd going but the usb isn't booting either.

BTW, if anyone is interested i figured out what the issue was. I had bitlockered my drive and since i switched over from a dell to a custom build, the hdd didnt recognize the TPM. I had to put it back on my old pc, decrypt it, and then hook it back up to the new pc and it worked fined.
