So where can I start. I've been trying to install Manjaro since around 6 hours so far alongside Windows 10.
Windows was first in MBR/BIOS mode.
Manjaro was installed in UEFI mode so that obviously didn't work out.
I got to the point where only one of those two worked, either booting straight into WIN 10 or Manjaro.
Then I went ahead and converted Win 10 MBR to GPT with gptgen.
After I did this, the Asus BIOS didn't even find the Kingston SSD first. I also can't boot into Windows anymore.
So I installed Manjaro in UEFI-mode from beginning and after updating grup, it boots into Manjaro and I can see again the SSD in BIOS.
But it still doesn't find the Windows boot to attach to grup when running sudo grup-update:
Generating grub configuration file ...

Found initrd fallback image: /boot/initramfs-4.14-x86_64-fallback.img
Found memtest86+ image: /boot/memtest86+/memtest.bin
Here are some commands I have run for troubleshooting:
I can still access the windows partition from Manjaro without problems where my files are.
Is there a way I can manually tell the system to look at sda1 for the Windows boot file?
