Windows 10: Change Boot Drive Errors

I have to return my corrupt SSD but need to format it before returning.I have installed a boot verion of Win 10 pro onto a spare HDD drive, but my pc will not boot from that drive because the SSD is still the boot drive. I have tried chaning letters etc, but keep getting the parameter is incorrect error.So how do I now make the HDD the system boot drive and not the ssd? Once the HDD is the system boot drive I can then formt the ssd?

CD drive error

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
Class
{4D36E965-E325-11CE-BFC1-08002BE10318}
4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

UpperFilters
LowerFilters
UpperFilters.bak
LowerFilters.bak
5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

And it likely has something to do with the emulated drive you have listed there.

Well, earlier today i was trying to setup a dual boot along with Xp and already had vista installed... so I made a partition on one of my HD's and went to install XP on it.. the instalation went back and I got an error that the CD was bad, so I rebooted and now I get the error Error Loading Operating System.. trying to figure out how to fix this.. I tryed playing in the BIOS along with using the Vista repair option but nothing helping.. my vista is on a different hard drive then where i tried to install XP to...not sure what else to do, I need to fix my boot file somehow... suggestions?

 

BCD errors and Boot drives

My computer screen went black out of nowhere, and upon booting up I received a Boot error and recovery message telling me that the BCD file is missing. I had previously created a back up of my windows 8.1, so I grabbed my flash drive and prayed. I have
checked tobmake sure that the USB drive is the preferred boot option, followed steps from numerous other posts with similar issues, and yet the same error occurs everytime I try to boot up my computer. Even with the drive. According to the menu, the usv exists
and is readable, and through connecting the USB to a different computer I can see that the files are all there and fine. Yet the error persists. If anyone has a suggestion I would really appreciate it...
