I've made the 1st 3 partitions according to the plan. Gave it the same names and all.
But the latest 3 I can't because SFS is not installed on the emergency bootdisk, so I can't do that yet.
At the moment I have 2 partitions back, only the 1st one not yet as I miss 1 cylinder, I'll try some more. Looks promising!
Start: Cylinder 2
Size: 305 Cylinders
Start next: Cylinder 308
305 + 2 = 307, but HDToolBox says this is 306 cylinders, not 305...
Edit: after fiddling around it worked (I'm really amazed how this works! When I compare it to Windows it would mean hell, you can't 'remake' partitions there), so now back to making it bootable (yeah, I forgot...), booting and doing the last 3 SFS partitions within the correct environment.
I don't know how to thank you but thanks a lot!
