Windows setup cannot install to the drive or partition you picked.
How to fix it
- Unplug every drive except the one you are installing to.
- In setup, delete the partitions on the target drive and select the unallocated space (this erases it).
- Check the BIOS: UEFI boot with the drive as GPT, or Legacy with MBR. Mixing them causes this error.
Is it serious?
A setup fix.
