GRUB parttool write error on usb
I was trying to hide some partitions from my USB flash drive using GRUB parttool but it failed.
Error message received: 'error:(hd0,msdos2) write error.
I was doing this to hide some debian iso's found on different partitions so that the installer would not recognize them both.
parttool (hd0,msdos2) hidden-
parttool (hd0,msdos4) hidden+
I am doing something wrong or it cannot be done on a USB drive? My own logic thinks the latter should work since the MBR partition table can be changed on USB's too but I am now stuck and your help is very appreciated.
