I am building a new PC. ( Ryzen 5 cpu, asrock mobo, msi Radeon RX 570, 16 gig ram, a gaming pc on a budget )
What I want is dual boot windows 10 and openSUSE Leap 15, for this there are two hard disk, one for windows one for Linux.
Windows 10 is already installed.
Main os will be Linux, and windows 10 for some (older) games that don’t have a Linux version.
I had already started and installed win 10, but he vid card I wanted to use, did not survive taking it out the old pc and putting it in the new pc.
**** happens so I ordered the RX 570.
Last time I looked in the bios it was not set to secure boot I think, as far as I understand things, because some hardware did not support that. ( old vid card)
Questions.
Can I just turn on secure boot in the bios, or will I have to reinstall win 10 ?
Do I need secure boot / eufi, is it better ?
The pc I am typing this with is also build by me, dual boot win 7 and leap 42.3, but it uses grub, I am new to secure boot and eufi.
Watched some vids of dual booting win 10 and suse, but there are doing it on a virtual machine, and it did not answer any of my questions / doubts.
If all goes well, will I get a uefi screen instead of a grub screen, were I can choose which os I want to start ?
While going through the bios ( eufi ? ) , I think I saw a box about a second os ?
Already have two usb sticks ready, one is win 10 , and one openSUSE leap 15.
So how to proceed?
Enable secure boot, put in Linux usb, and reboot ? or is it not that easy ?
