Support

hello! I am trying to dual boot manjaro and windows 10 on my device. I have allocated 200 Gb in my partition manager in windows, but when i boot manjaro from my USB flash drive and launch the manjaro installer, the installer doesnt detect the partition i made. What should i do?

Thanks for your time!
