post screenshot of easus partition manager so I can see all disks and partitions. Is disk1 a mbr disk or or gpt disk?
If already a mbr disk:
- remove the 200MB partition on SSD
- add the space (which is now unallocated) eventually to S
- mark S active.
Don't bother disk letters about now. They are just defined in registry. It's easy to fix.
post screenshot of disk management afterwards
