Thanks for the reply....
This is the problem, with fixmbr you can fix a windows Installation but, in my case, windows is not installed on the external hard disk...
all I want to do is remove Grub from MBR and I think this should be Ok:
# install -mbr /dev/sdb
I think this should give me a new MBR....what do you think???
Or maybe I'd better do this:
# dd if=/dev/zero of=/dev/hda bs=446 count=1
This should zero the MBR but not the partition Table (because the other 64 bytes aren't erased)
I think the second is correct but I'm not sure...what do you think???
EDIT: I googled for the first command and it seems is not correct while here they say the second should be OK:http://www.linuxquestions.org/questions ... y.-606489/
Can someone confirm this?
P.S.: my intention is not to criticize, but why don't we have the option of installing Grub on a specified partition in the Mint Installer (instead of installing it in the MBR)?
