I Screwed Up

[UTCD]

I was creating a boot drive for a pile of parts that were on the way. I had a 120GB ssd laying around that I wanted to use for the new machine. I installed it into my existing machine and used a windows 10 boot usb to install windows into it. Here is where I screwed up. I didnt disconnect the existing 250GB boot drive in the machine. So now when I boot it acts as a dual boot system. I can boot the clean install on the 120 or the existing system on the 250. I didnt lose and data thankfully. But if I remove the new 120 i cant get the old install to boot at all. I get a black screen with "insert boot media and press any key" message. I tried using the usb stick to repair winds but that didnt work. I dont want to do a clean install on my old drive. I want to keep everything intact just the way it is. Any ideas?

 

TIA

Go into BIOS and select the 250 as the boot option and see if that works to get you back to the desktop.

Try fixing the master boot record using media creation tool

So i tried both.

TheGlenlivet when i enter bios the only drive that shows up is the 250 and it is in the top position and i still receive insert boot media. 

C2dan88 i followed your link and did everything that it said even the more in depth portion and that did not work as well. i reinstalled the 120 and the pc fired right up and asked which windows version i would like to boot, "windows 10 volume 1" or "windows 10 volume 4".

 

thank both of you for your help.
