Many Thanks for the answers Thomas
So im kinda screwed. Because even my Workbench disk got this problem. Thats the only way to get to a Shell window

?
And do i have to switch the power off everytime i tried to run a disk?
Well 1 thing i have to ask then, why those some of the games run when you remove the protection?
Well the only way to really fix this problem is to get fresh new games then? Well i saw some solution to use Amiga Explorer to connect to your amiga with a Null modem cable, but since my motherbord don't support this im kinda screwed, is there any other way?
After a few disk try with the reboot thing everytime my amiga starts up now with the power off and on, it gives a System Failure Error: 0000 0000 Task: 00002600 - What i found out, is this error just because i turn off the power and then on again?
And some of the games make the Green light to blink? in the old days when i was a kid i just ignore it and tough the game didnt work because it had a virus, but is this also the bootblock thingy?
