Ok,
for HDs or compact-flash larger then 4GB i read the info about it, and i understand what to do, i just don't get why the first partition should be less equal then 4GB if the second one could be 100GB.
what is the difference? If he recognizes the 2nd as 100GB why he doesn't do it for the 1st as 4GB? Is it because is the partition that has the boot ?
