I want to thank everybody for the help, especially for Eric.
The solution was:
fdisk /dev/hdd
then go to expert mode (x)
print the partition table (p)
move the beginning of the partition (b) - where I increased the start number
by 63
write to disk and exit (w)
Reboot and everything is fine.
I'm so happy :)

Gergely

PS: I made a typo in my previous letter. Instead of 5132575420 I should have
written 5132574720 in case anybody wonders...
