Hi all, I would like to build a bootable USB which behaves as a normal installation (saving files, updates etc.) and which is reasonably portable across various computers. I am following
https://wiki.gentoo.org/wiki/Install_Gentoo_on_a_bootable_USB_stick/en which seems to describe what I am looking for. I am adapting the above instructions to use grub2 with efi, using one partition for /boot and another for /boot/efi . I can boot the USB once, but then at the next reboot my hard drive installation is corrupted and can not be booted anymore. I have to reinstall grub from another live USB. My questions: 1) is the above link a good reference for what I am trying to do? 2) what can corrupt the main driver when booting from the USB installation? 3) is there another reference for what I am doing? (live USB are a different thing, since unless I am mistaken the installation can not be changed, although it is possible to mount a writable partition) The fact that the main installation is corrupted is of course what worries me most, since for this USB to be make sense I should be more or less confident that at least it does not corrupt the main installation. I have no problems providing additional details, if I knew what would be useful. Thank you! Marco
