The issue was with partition system. I switched to MBR (using ventoy). Now I was able to get into antix’s(386-core) bootloader from there (I dont know if my terminology is right).

I booted into antix but system crashed after kernel loaded. This was the first time. Second time it got stuck in loading hardware specific modules screen

Thanks for helping out.

How do i burn CD with installer? The only CD player I have is in the pc and an old Samsung CD player
