Ubuntu in the Boot Menu

[mahesh]

Hi all! I am very new to Linux and the Ubuntu community. I wanted to dual boot Ubuntu on my PC using two separate SSDs for Windows and Ubuntu. When I installed Ubuntu, I didn't think to disconnect the other hard drives from my computer (there is a total of four). I got Ubuntu installed on the correct SSD but for some reason it installed on the other drives even when I selected the one I wanted it on.

Now here's my issue: when I go into my boot menu, I see four drives. The first drive [SATA4: CT250MX500SSD1] is the drive I wanted Ubuntu on. The second drive [SATA 1: Samsung 850 EVO 1 TB] is my Windows OS. However, this second drive is also listed as having Ubuntu on it. The last drive [Seagate Expansion Desk 9401] is my external HDD connected via USB. This too has Ubuntu on it.

I have gone into Disk Management on Windows but I don't see any unusual partitions. I went into Command Prompt in Windows and deleted the UEFI Boot entry for the two drives using "bcdedit /enum firmware." Any suggestions on how I can fix this?
