    Re: USB KEY LIVE INSTALL questions.

    I wanted to add: if you install to a pendrive, you should disconnect all other drives except the live one (source) and the one to be install onto (target). If you have internal hard drives connected, the installer 'wants to' include them into the boot environment, which is bad, if you want to use the pendrive on other computers.

    If it is 20-30 MB/s both read and write I think it is good enough But still, you might find it slow writing many small files.

    If you boot a live Ubuntu system from a CD or USB drive, it does not matter what system it is on the computer hard drive.

    It is more complicated to disconnect the internal drive from a laptop than from a desktop/tower computer, but it is not too difficult.

    But if you don't want to disconnect it, you can be very careful, when selecting the system partition and where to put grub. Select the manual selection of partitions, choose 'Something else'. Grub should be put onto the head of the target USB pendrive (not to a partition). If the target drive is /dev/sdc, grub should be written to /dev/sdc (not /dev/sdc1, /dev/sdc2 ...).

    And after installation, you might want to change the grub settings (because it will probably identify windows on the internal drive, and make a boot option for it), unless of course, you want to have the windows option there.

    If you don't want windows in the grub menu on the boot from the usb, just remove the os-prober, once you are installed run in the install.
    Code:
    sudo apt-get remove os-prober
    Then run to update grub.
    Code:
    sudo update-grub

    Ok now I'm getting a little confused. When installing it'll know the drive letters correct I just have it install to the root of the usb key correct?

    When you boot the live cd and have the stick plugged in run this command to identify the stick.

    Code:
    sudo fdisk -l
    You will see the internal drive and the stick listed. You are looking for the first three letters of the stick, it will probably be sdb.

    When you get to the something other option in the install and open that gui you will have a drop down giving you choices of where grub goes. If the stick is sdb choose the sdb option. No partition numbers here.

    Before any of this really make sure you have a recovery or install disc of windows. If this is W7 you can make one in the windows backup and recovery there is a option there.

    This is a tool you must have anyway, it allows you to make repairs and run a terminal for windows, for reloading the internal HD's mbr if ever needed amongst other repairs if ever needed.

    If you decide to use gparted as suggested on the live cd to make the ext4 partition on the stick that will tell you the sticks letters.

    You will have to use the custom install no matter what here.
