Small problem after fixing GRUB menu

[Atinesh]

Hello guys, I have a PC with 3 hard disks

 

SSD #1 (Dedicated to Ubuntu 18.04 OS) [SATA3_0]
SSD #2 (Dedicated to Windows 10 OS) [SATA3_1]
HDD #3 (For other files) [SATA3_2]

 

Usually, when I boot my system, I get a GRUB menu from where I can choose a specific OS to load (Ubuntu or Windows). For some reason, I had to Reinstall Windows after which I was unable to load Windows from the GRUB menu as it was got corrupted. To fix it, I followed this post and repaired the GRUB

 

Everything is fine now, I can load both OS without any problem, but there is one small confusion, when I checked the boot order in BIOS I found one extra entry ubuntu (SATA3_1) i.e. Ubuntu boot manager on Windows hard disk. Usually, there should be only 2 options 

 

Windows Boot Manager (SATA3_1)
ubuntu (SATA3_0)

 

 

 

If I boot from ubuntu (SATA3_0) a GRUB menu appears where I can choose the OS to load and both OS loads without any problem, but when I boot from ubuntu (SATA3_1) a GRUB terminal appears 

 

 

So my question is can I delete this entry ubuntu (SATA3_1) somehow, does deleting it will corrupt Windows or Ubuntu boot manager or should I just leave it, as it's not creating any problem

Have you tried the command as root

update-grub

?

Usually, in a dual-boot, Linux is installed lastly.

BTW, thanks for the unixmen link!

After clicking “Recommended  repair” I haven’t issued any command in terminal

No it won't do anything to the OS. If you use a grub editor or edit it manually all you're doing is editing the "launcher" if you like. I haven't done it in a few years or more, but pretty sure there are grub editors for linux GUI or windows even if you are inclined that way. doing a search for grub editor should bring up a few options.

I tried editing grub configuration file /boot/grub/grub.conf in Ubuntu but I couldn't find that entry
