SOLVED LM 19 - GUI way to update boot options after replacing HDD with SSD?

[MintyMorkyMindy]

Hi,

Is there a GUI option to update the boot options for LM19 ?

I replaced a HDD with an OS, for a SDD and the same OS newly installed.

At boot, when I choose the other OS, I am presented with starting both OS, only one of which exists, as the other was removed with the HDD.

I want to edit out the OS at boot that no longer exists.

Is there a way this can be done with GUI only.

Thanks

Yes, there is, but those of us with experience highly recommend against it because it will, at some point, totally mess up your GruB. Instead, try this in a terminal:

sudo update-grub

I bet I know which GUI way of updating boot options catweazel is referring to, and I concur: you don't want to do that. I am currently booting my computer from a Grub2 boot CD, then booting Mint from there, because there doesn't seem to be any way to recover from using that GUI way. (I haven't bothered to fix it since I rarely reboot the computer anyway, and I will be installing Mint 19 soon anyway.)

I tried:
sudo update-grub

When I rebooted and selected Win10, the removed HDD Win10 option was still visible.

I want to edit this, the Windows Boot Manager, to keep the updated SDD Win10, and remove the HDD Win10 that isn't there.

"Found Windows Boot Manager on /dev/sde1@/EFI/Microsoft/Boot/bootmgfw.efi"

Thanks.

Working after reinstall of LM19 and Win10.

I used various boot/grub2 programs in an attempt to fix this problem.

The problem could not be resolved. I suspect the following is the cause, that LM19 and Win10 were installed under differing BIOS settings. They need to be installed with the same BIOS settings. UEFI is preferred.

The following is an explanation how I resolved this problem, trial and error.

I have a new computer, built December 2017, so the components are UEFI compatible I would think.

My settings in BIOS:

Fast Boot = Enabled
Secure Boot (OS Type) = Other OS

Launch CSM (Compatibility Support Module) = Enabled
Boot Device Control = UEFI and Legacy OPROM
Boot from Network Devices = UEFI driver first
Boot from Storage Devices = UEFI driver first
Boot from PCI-E Expansion Devices = UEFI driver first

Secure Boot State = Enabled (defaults installed)

Process:

1. Turn off the Internet connection.
2. Remove drives other than for LM19 and Win10.
3. Within BIOS boot USB drive (I use USB 3.1).
4. Install Win10. Took about 7 minutes approx.
5. Install LM19. Took about 4 minutes approx.
6. Confirm normal boot to operating system selection.
7. Reconnect the internet connection and complete LM19 and Win10 installs.

I only use Win10 for games. This software may be helpful, internetoffsetup_3-0-1.exe It is a toggle ON/OFF for the internet.

I hope the above helps others seeking a solution to similar challenges.

NB

I spent hours testing installs and research before I figured this all out.
