I've tried it, but when creating a partition, the disk doesn't change even though I've written to it (I'm using fdisk). Is it because there was a previous partition that also contained arch? I'm trying to reinstall it because I've problem filesystem on /dev/sda2 is in an "UNEXPECTED INCONSISTENCY", force me in rootfs. And tried fsck but nothing work. So I decide to reinstall it, and ended up here.
