I'm trying to install CentOS 7 to HP Z440 workstation having (some kind of) RAID setup. The default installation fails with screen full of garbled text apparently with some kind of serious system error (no mouse clicks work), and text-based installation (using linux text) fails with Anaconda stacktrace from blivet.errors.DeviceTreeError. If I press "Debug", I get to see the error being thrown from addUdevPartitionDevice, and on continuing there the error seems to be "DeviceTreeError: failed to scan disk RAID1Volume_0".

Based on these bug reports and especially this comment it seems to be a known issue when partition data has issues.

The question is, how to go forward from here? I guess I need to repartition the disks, but does CentOS boot disk offer something to do it, and if so, what? What am I exactly meant to do, delete the partitions and recreate them, or something else? I don't need to store any data from this computer, everything is ok to wipe away.

Edit: I managed to get into Anaconda Shell in text-based install using alt+f2, and fdisk -l tells me that "Partition 2 does not start on physical sector boundary", which is probably my issue.

Edit2: I also see "Sector size (logical/physical): 512 bytes / 4096 bytes" in there, making the question probably related to this issue. I could just recreate the partition, but what about the raid setup? Currently fdisk and p says:
