### describe the problem

#### Description of the issue

It is in a way a followup of this bug: https://github.com/archlinux/archinstall/issues/2849

I was trying last git code in a qemu vm and I managed this partition scheme by hand:

/dev/vda1 ; 512 Mb ; /boot ; fat32
/dev/vda2 : 32 Gb ; / ; ext4
/dev/vda3 : 96 Gb ; /home ; ext4

Everything goes well during edition, but when the installer starts managing the partition, it crashed.

Error log: https://0x0.st/XnfN.log

Same error message as #2889

The log shows all three partitions have the same start value, the default start sector 34. This is not a valid configuration and is easily reproducible. A check should be added for invalid configurations to prevent proceeding with partitioning.

[Torxed]

Agreed, ideally we should validate the if positions overlap and if they fit within the bounds of the disk(s), and take into account if we wipe/free up space
