Bug 26961

To make sure I understand: you changed the motherboard & retained the same disc. Then used a Mageia 7.1 ISO to update the installed system for the changed hardware? If so, did you notice what if anything was updated? Possibly nothing if you did not enable on-line media.
Was that step necessary? The processor/memory should not matter. I think USB etc is detected on boot. The changed video hardware would be the main thing: was there a change of driver from the previous nvidia gtx 9800+ to the new nvidia gtx 1060 ?
Did you try booting the new system without any change?
In what way does the 'updated' system not boot? To a blank scree, a Grub2 prompt? Do you see the Grub2 boot menu, and it does not boot from that?
Are you able to boot to a virtual console - rescue mode, or Ctl/Alt/Fn ?

yes

I think so, no package were downloaded and installed

yes, I have enabled internet link and all media depos <core, nonfree,tainted><release,updates>

no change, strangely my gtx 9800+ works very well with nvidia-430-64-8.mga7.nonfree drivers

yes, but unsuccessfully

at the beginning I see the grub2 menu, and the boot process initiates normally; but a couple of steps after "research of new peripherals", the boot process stalls, and at the left bottom corner of the screen, a dash is endless blinking.
the best is that I do a snapshot of the screen just at this moment, when the boot process stalls

If you try rescue mode, do you get to a prompt?

If not, i would try a reinstall, keep in all partitions, update media enabled.
That is what you tried?

Failing that, i would try the same but only keeping /home (and if you have other partitions with user data)

> If you try rescue mode, do you get to a prompt?
 yes, I attempted two boot methods:
 - on kernel-5.6.14-server-2 with no option
 - on kernel-5.6.14-desktop-2 with options faisafe nokmsboot
both failed as above describded

possible, but I don't remember the line command which keeps in memory all already installed packages in order to reinstall them at once
> That is what you tried?
I didn't yet tried

I did this once years ago (transplanted a harddrive from one laptop to another with different graphics hardware).  The boot got to harddrake2 ("Checking for new hardware") and appeared to stall.  I left the machine, not knowing what to do other than reinstall.  I happened to check back an hour or two later, and the boot had completed and graphics worked fine.

I have no idea what the machine was doing all that time, but I was quite impressed that MGA had figured everything out and reconfigured the system for the new hardware.

thank you very much for this good new; perhaps I am too impatient and hate to wait a long while; I'll follow your experience and report the result on this post

I have checked on the nvidia's site that the driver nvidia-430.64 is suitable for the card gtx-1060

the problem seems to be solved:
1) when upgrading with the usb key iso media, I have forgotten to set the graphic driver to "Geforce 635 serie and later"
2) it is necessary to add the boot option kernel "nokmsboot"
and now with the new stuff I boot much more quickly than with the old one

Godd. Thank you Peter for your efforts.
