Fernando Meira wrote: Hi Francesco, thanks for your reply. You gave me a new idea. I can't create 2 partition as you proposed, but only one. This because I already have 3 primary and 1 extended. Yes.. big mess.. have to fix it later... So, what I will do is this: - leave around 32M in the beginning of the disk for a future /boot when I can alter the partitions table freely. - create hda1, starting after 32M until the end of spare disk. sound good, 50 Mb instead of 32? 18 Mb are not so much nowadays. This also don't change the partition scheme of your HD probably making win more happy. - move the system from hda4 to hda1, the way you said. BTW, cp -a or rsync would get better results? cp -a work for me (TM) , rsync make not much sense when the destination is empty. Question: I had a bootable flag on my windoze partition before (hda1), though /boot was in hda4. Now should I move it to where /boot will stay, right? keep the bootable flag *only* on the win partition, it's the only one that need it. Thanks, Fernando.
