dont send screenshots, just log into manjaro from the live usb and copy the outputs … youre just wasting time with screenshot, when you can just copy the outputs from terminal …
freeimage.host/i/SrSGov
close the terminal, connect to internet, open terminal and run this:
sudo manjaro-chroot -a
then run update again:
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
copy these commands in the terminal, if there are errors copy them!!!
ok ok wait
i cant send error 
see screenshot please
freeimage.host/i/SrSGov
you just send me the same as the previous one… i told you above what commands you have to run, and that you need to be chrooted after you connected to internet…
I also executed your instructions, where is the problem?
so were there any errors running the mirrors/syyu command?
Yes, there was a problem. I sent you the link of the last screenshot, but you did not see it
this link:
freeimage.host/i/SrSGov
you sending me again the same screenshot where you run only the syyu command without the mirrors …
sorry bro I understand now
freeimage.host/i/SrrHwg
ok now post output from:
mhwd-kernel -li && mhwd -l && mhwd -li
freeimage.host/i/Srr7l2
ok…
so when you boot manjaro you just get stuck in black screen?
is there any message during booting?
Yes, now when I try to enter Manjaro, the screen goes black, then my system turns off and turns on again, but this time it enters the BIOS settings.
so no message?
no message
lets install a different kernel and then we reinstall grub:
install kernel:
mhwd-kernel -i linux510
errors copy here
ok bro it is downloading …
freeimage.host/i/Srrbsf
