also make sure windows 10 is installed to the first disk in the bios and it wont overwrite grub on you 
I think I installed Linux first. I was rebuilding my PC at the time and since I used two separate SSDs when I did the Windows 10 install I disconnected all other drives just in case the Windows 10 instalerl decided to screw with drives it shouldnât.
But if thatâs not an option for you, Iâd recommend installing Windows 10 first as others have suggested.
Well since sata ssdâs are dirt cheap right now,
and basically more then fast enough for windows.
I would probablly buy a cheap 128GB / 256GB SSD.
Then put windows on that one, and use the other ssd for linux.
Then i would make a small 2GB partition on the HDD,
and use that as the boot drive for grub.
Or you could make a small partition on the 2TB linux drive as well ofc.
If you are installing on 2 seperate drives you can set them up any way you want to.
dual booting on a single drive! you can install windows first but you run the risk of possible messing up the linux partition during routine updates and maintenance operations in windows. (not that it can happen often but the risk is there)
if you wist to install linux first write a seperate partition for windows and edit the grub file to start windows first (If that is your choice).
the computer will boot the first os in the grub file by default.
this link might help.
Not necessarily.
If I were in your place, I would do it like that âŚ
Two SSDs, one for each OS. For Windows, you can buy some cheap SATA 128GB and it is enough, since linux is to be the main OS and will be located on this large nvme. Then install the operating systems separately per disk. And prepare some USB pen with boot manager. In this way, we obtain two completely separate drives with the operating system, and the choice of which OS to start is the process selected from BM from USB.
In bios you only need to set usb with BM as boot and thatâs it.
Then you avoid having to enter the bios.
Then you avoid physical disk swapping.
Then you avoid holding boot for both systems on the first disk.
Full separation and convenient simple OS selection.
Well, as someone is very new to Linux, but loving every minute of it, thank you so much TimHolus! I really do appreciate the positive people, like yourself, that have been guiding me on this journey. I feel that Linux or something very similar to Linux is the future, perhaps, and giving him the large SSD to focus onâŚ
i will look into bootloaders
oh gotcha thanks very much
Wow, youâre so very helpful. I must say, you are very kind and highly intelligent! Thanks for taking the time to be one of the best at Level1techs.

Howâs your sonâs computer progressing? 
Its amazing, the RGB on the 5700XT blinks white from whatever color, but none of the major issues people are having. With PopOS, Deadbeef doesnât play, the play button wonât play, not sure. Overall, it has been a very amazing experience. The boot loader from USB, is such a wonderful solution. The entire experience, has been full of little challenges and those being fixed with help from all the great comments at Level1. We are already planning our next all AMD build! I wish more people knew how with research and a bit of trial and error, you can build a screaming beast of a PC! Has been so much fun! He plays AAA games with max settings in most games! Forza is the only game that crashes, but its a Microsoft title, and its rare! Thanks so much for asking!

What boot loader did you choose?
Went with Grub as its very recommended. Iâm not entirely sure how I made it all work just right, but it does! Any recommendations? At least for the next build or replacement?
I know, I ask a lot of questions, but: I would really love to learn Linux in a very comprehensive way. Not just the forum level, I mean a true mastery of it. Any ideas on where is best to start?
actually, not sure, which bootloader is doing what, haha. The more I thought about it, the more I realized if we do nothing it boots into windows 10. If we hit F11 it boots to Linux. At first I thought it was the USB, but now I think its a boot manager in the bios? I will try and work on it soon, but if you have any advice on the best boot manager, pass it on, stay safe and healthy out there.
