I use a fixed PC ASUS ROG G20 -Intel (R) Core (TM) i7-4790 CPU @ 3.60GHz - NVIDIA GTX 970 - 8000 ram with of course a bios uefi. This PC comes with Windows 10 by default.
At first, I replaced the hard drive to put an equivalent but blank disk. To use NuTyX, bios version, I have to modify the settings of the dedicated bios by default to windows 10. In summary, I put in the drop-down menu Other OS in place of Windows. From there I was able to install the BIOS version of NUTYX with a serious problem, I could only use kernels 4.4.x. I was therefore unable to run a kernel 4.9 or 4.10. At the time, Tnut did not fully grasp the problem and had no real solutions to propose to me. The time to go and the demand for UEFI has begun to become more and more pressing.
Secondly, Tnut offered to test its NuTyX iso. To make it simple, I told him that no UEFI distribution was installed. I tested archlinux, archanywhere, manjaro, mint with 4.4, opensuse, ubuntu gnome etc. I have to say that I have had more disappointments and failures.
Tnut imperturbable told me, I would not let you go before it works on your PC. I agree but I tell you frankly, I did not believe it.
Third time, I test the iso of Tnut. Before launching them, I go through the bios and I note that the iso is recognized in BIOS version and in UEFI version. There was nothing new, the others were recognized in the same way. I continue and boot by choosing the UEFI version. It launches without problem and I arrive on the interface. I type as indicated (take the time to read what appears on the screen) "-ec" and I end up with the possibility of commanding and modifying and adding certain functions.
Tnut asks me to add after ... ... ro quiet pci = nocrs pci = norealloc. Then I am what is written at the bottom of the screen and boot without problem on the NuTyX installation in UEFI.
Fourthly, the NuTyX iso UEFI is operational. You now have to install NuTyX in UEFI. You will believe me if you want but the suite is ultra simple. The only difficulty is to partition your hard drive into GPT.
We'll do the simplest. :
1 / you go into partitioning. You choose fdisk and then the help key is 'm'. You read and choose 'g' as GPT then you save it all with 'w'.
2 / you switch to cfdisk, it will be more visual. You create at least three partitions.
--the BOOT partition: size about 300 MB and especially in TYPE, you define it as partition system UEFI
-a SWAP partition (for size, you are free from 1 to 4 GB), it should go. Swap partition type.
-To finish, one or two system partitions is / and personal / home. I leave you free, do not forget to mention the TYPE of the score.
You write by typing yes and exit cfdisk.
3 / Back in the installation interface, you format. I put BTFRS on INFO.
4 / You Install, if you are not in GPT, you will get an error message.
The usual process of your NuTyX follows its path. You log in and password and you arrive immediately at the end of your installation.
Frankly, it's really too simple to install in UEFI with NuTyX. It's a bit of a problem at first but it's a disconcerting simplicity.
