but after some time (when filesystem drivers are loaded I think) the machine just reboots.
What you describe is a bit too "vague" to pinpoint the problem, I am afraid.
Can you try to better describe what's happening?
I.e. try to list what you see happening until you experience the reboot.
Also please post some details on the actual PC you are trying to install to, laptop/desktop, make/model, type and size of hard disk(s), how it/they are partitioned, are you truing to install from a USB stick or USB hard disk, etc.
Maybe dumb recommendations

, but unplug any other USB device (except mouse/keyboard) and make sure you are putting the USB stick or hard disk to one of the USB sockets on the back of the PC if desktop, (the ones soldered to motherboard, NOT the front ones connected to a cable).
Do not use external USB hubs.

It doesn't make any difference whether I use PeToUSB and FAT oder the HP-Tool and NTFS as filesystem.
Yes, that should make not any difference since you are well past the booting phase.
