[ SOLVED ] After installing how do I set grub to chainload old windows10 drive?

[firenice03]

Cool Deal!!! Glad to hear your set up

I have Linux Lite 4.2 and grub installed on ssd with the grub menu showing at boot.

My old windows 10 drive is still attached and mounted so I can browse files.

I can boot the old win10 drive through the bios boot menu, but would like to add the option into the grub menu.

Can anyone suggest a way to add an entry to chainload the windows10 drive through the grub menu?

Was the Old Windows Drive not attached when LL was installed?

LL Grub will check for other installed OS's and add to grub..
- If it was not - from within LL open terminal and run the following:

Code: [Select]

sudo update-grub
enter your password allow it to process then reboot you should see Windows..
I have an output example here:

Yeah I just noticed that.  My grub menu was graphical and the text was soooo small on my 1080p monitor I couldn't read it.

I edited

Code: [Select]

etc/default/grub to change the line

Code: [Select]

GRUB_TERMINAL=console so I could read the entries from text mode menu and when I ran

Code: [Select]

sudo update-grub I noticed it found my windows drive automatically.  So when the text menu came up at boot and I could read it I noticed windows 10 was there already. 

In

Code: [Select]

/etc/grub.d I moved

Code: [Select]

30_os-prober to

Code: [Select]

11_os-prober so my windows drive shows up after linux but before the memtest86+ entries.

Hello timbuck2,
