Windows 10: Where would I put GRUB for a dual boot?

Yes, I know this question belongs in the kali linux forum. Here it is there:

This forum is just way more helpful.

I am trying to do a dual boot on windows 10 with a Gateway NE56R49U laptop.
My partitions are in the following picture: [ ext4 is where Kali is going]
Imgur

Which partition do I install GRUB to?
ie: (/dev/sda)

Do I have to do anything to get it to boot correctly since linux requires Legacy Bios and Windows requires UEFI? If so, what? If I wanted to install Ubuntu, should I do that first and then install Kali? Would that make this easier for me?

I appreciate all the help I can get.
Thanks.

No Boot Menu (to select OS) after Dual Booting Windows 7 and Windows 10. Please help

According to howtogeek, it was possible during the Tech Preview.

How to Dual-Boot Windows 10 with Windows 7 or 8

Is what happened to z.a.s a bug or is this intended? In either way, would installing GRUB help?

I, myself, don't have the same problem (GRUB works perfectly with my Win10/Ubuntu setup), but I am interested.

 

It depends which bootloader you want to use. Personally, I use Grub, specifically Burg - this is what it looks like:





I have Mint and Windows on my SSD (dev/sda) - which has Grub in that MBR.

Recently I messed with the partitions on my second HDD (dev/sdb) and lost Windows boot - Grub's osprober found windows OK but windows still would not boot
Macruim Reflect's "fix Windows boot" only managed to overwrite Grub, but the boot error persisted.
The way I fixed it was re-installing Grub from Live, then running diskpart from the Win install media to get the system and windows drive letters - ran chkdsk /f /r on both those - came out clean - what fixed it was bcdboot [windows drive letter]:/windows.

Just relaying my experience as something to bear in mind when setting yours up.

 

And which OS you consider primary, I suppose.

I took the non-conventional approach.
This is on a MBR / BIOS machine
- Win8.1 primary, Win10 as 2nd OS, Linux Mint as 3rd OS

I GParted two separate partitions (ext4 & linux-swap) before installing Linux Mint
I had to tell the installation to use the ext4 part (it was flagged "do not use") - set it to use ext4 journalling
I selected the ext4 part for the install and set the mount point as / on that part
(be careful - the install seems to want to use to sda. just change it to your ext4 sda ... sda6 in your pic)

Make sure to remove the the Boot flag from the ext4 part if present
I used unallocated space in the extended partition for both Linux parts (as logical parts)
edit-

I don't see a linux-swap part in your pic.
I'm not certain, but suggest that you create a small part in GParted with a type linux-swap
I used 1024 and it seems fine

Then you have to tell Bootmgr about Grub- I used EasyBCD
Pick the Linux OS tab
Point to the ext4 part

The advantage?
Each OS leaves the other boot alone - sure you might have to reconfigure Bootmgr to know about Grub after an update from MS, but you should always be able to boot to Windows.

Superfly's post below led me to this: Dual boot Windows 7 and Linux/UNIX (also MBR / BIOS information.

Thanx Bill,

The other thing is... for adding Linux boot to the Windows Bootmgr in UEFI, try BootNext tool - boot any Linux or Windows from Windows 8.1/7/Vista - I don't think there is a need for legacy mode.

 

Thank you Superfly,

I wasn't sure about UEFI ... I added an MBR disclaimer in my post.

You're talking about legacy mode for Linux, yes?
I agree.
