Hi!

I know i can find my answer here

 

Brief about me: I'm a visual designer, front-end designer, web+android developer avid gamer and a tech enthusiast/savvy.

My system spec:
Intel Core i5 4590K

16GB (8+8) DDR3 Corsair Vengeance

Gigabyte G1 Gaming 4GB 960GTX

3TB : 1TB + 2TB

Partition Detail:

• 1TB:
  • [A1] - 200GB · Windows 10 Pro OS
  • [A2] - 500GB · Random file storage
  • [A3] - 200GB
• 2TB HDD
  • [B1] - 200GB · Mac OS El Capitan
  • [B2] - 1800GB · Main Work Drive shared between both the OSs

To switch between the OS, i choose the desired OS at the Boot Options Menu.

 

I really love to watch people working on Linux, the feel & sound of key presses and all those nerdy things really amazes me. So I downloaded Ubuntu and installed in a USB 3.0 SanDisk 64GB USB Drive. But I've got an issue. It seems like I didn't read the guides thoroughly and a part of Linux installation which I thought will be confined within my 64GB USB Drive has installed in the system somewhere due to which at runtime I start getting an option in the Boot Options list to boot Ubuntu even when USB Drive isn't attached. (I guess its something to do with a thing called GRUB). Now, I want to remove that piece of software/bootloader/anything which is causing it to list in the boot options and re-install the OS such that my USB Drive is solely capable to run Ubuntu with no dependencies on any of my other two hard drives.

This is in the bios due to the efi options. This isn't on any of your drives, and won't cause any issues.

Hi, Thanks for prompt reply. So do you mean that even if i disconnect the two hard drives, I'll get the Ubuntu in the boot option list? is it a necessary component? Can it be hidden?

Also, let suppose I let the current settings be, does it mean that my ubuntu installation (residing on the USB Drive) is limited to my system because only my BIOS has the boot loader info? OR does it mean that irrespective of boot loader installed, I can run the Ubuntu from my USB anywhere?

Depends on the board, I have systems that still have os's from a year ago and lots of installs later.

 

You can use that install on other systems.
