Another installing Windows after Linux thread..

So right now i'm running mint 19 cinnamon. I installed W7 on my second hdd. So of course, the grub menu is gone and boots straight into W7. So I booted Mint live cd/usb. I used the terminal and boot repair, to repair the grub menu. But now W7 isn't showing in the grub menu. I'm just going around in circles.

So what can I do now?

 

Are you have UEFI-based motherboard or BIOS-based?
On UEFI-based motherboards one can just press some key and choose bootloader. For my laptop it is F12.
On BIOS-based motherboards use GRUB's chainloading to boot from GRUB to Windows bootloader.

 

I'm on UEFI. I think mine is ESC. I've tried that, but it didn't work. I'll try again.

 

You did "sudo update-grub", right?

Maybe you can try the Boot-Repair-Disk: https://sourceforge.net/p/boot-repair-cd/home/Home/
In that situation, I've always used this with success.

 

That's what I did, and followed the process with boot repair and sudo/terminal

 

boot straight into linux have windows hard drive disconnected if possible when on linux desk top reconnect windows drive
bring terminal up and sudo update-grub enter and watch see if windows loader etc at bottom of list in terminal type reboot enter
see what happens just a thought . Or from windows you could try using EasyBCD

Infected,

Have you fixed it?

 

Boot into mint, and then run grub update. You will see on the command line if it detects the disk/partitions and adds the win7 entry.
Mrk

 

If you do not fixet it, could you provide some logs?

Code:

df | grep "/$"
gdisk -l /dev/sd[a,b,c]

 

Not Yet, I'll try what MRK suggested.

Thanks, I'll give this a go.

Will do.

 

That's the thing. After installing W7 after linux, the grub menu is gone and it boots straight into W7. Should I try this with a mint live cd/usb? Will that yield the same results?

 

Ok, this is what's happening.

If I leave UEFI enabled, it boots straight into W7. If i disable UEFI, it boots straight into Mint.

If i leave UEFI enabled, and keep pressing the esc key after the "intel nuc" menu, it bypasses W7 and boots into Mint. lol

 

@Infected Which of the two situations is it?
You have fixed grub and do not see windows in the grub menu? or
You have installed windows and grub disappeared and you haven't fixed it yet?
Have you installed Linux and windows in uefi mode? or legacy mode? or one in uefi and the other in legacy?

 

The 2nd one. I honestly can't remember which I installed it in, uefi or legacy.

 

Now I saw your previous post. It seems you have installed grub in the mbr instead of the esp partition. (mint boots in legacy mode; probably after you fixed it)
As an advice either install both in legacy mode by disabling uefi boot and secure boot
or disable legacy mode and install them in uefi mode (you can reanable legacy if needed after you've installed both of them).

 

@Infected the "esc" key should not do anything; it only removes the nuc preboot screen and skips some initial tests = you don't have to wait for the 10 seconds (default setting) to pass for proceeding with the OS boot.
F10 is the key for the boot menu on nucs.

It does though, I'm not sure why. I use the F10 when booting from usb's.

 

It seems to be a bug in your bios version (or is an undocumented feature that reverts the default boot priority from uefi to legacy). check if there is a new one or if it is the latest open a support ticket at intel (their support is top-notch)

 

Infected,

In your UEFI BIOS do you have CSM (Compatibility Support Module)? Is it set to Disabled? Is your Secure Boot Enabled or Disabled?

Having the CSM disabled prevents MBR disks from booting so you can't inadvertently install a non UEFI OS.

 

Brian "Compatibility Support Module" and Intel's "Legacy mode" are the same thing.

 

I'm not going to worry about it. As long as I can get to both OS's without going into bios, I'm good. Thanks for all the help.
