2 Questions.
1;If I boot linux off a usb can I install it onto my internal harddrive so I can take the USB out of my computer? Or am I able to remove the USB after booting it off of it?

2;Anyway to remove windows and have only Linux?

Hi,
This is normally what happens when you install using a usb thumb drive. You first boot from the USB device and the OS is installed to the hard drive. Then you reboot into your new OS from the hard drive.
Without rebooting? If so, then this will depend on the iso you are using.

If you give us the bigger picture regrading what you are actually trying to do you'll likely find it easier to get relevant information.

Yes. Most installers will give the option of using the entire hard disk, meaning that anything previously on there (including installations of other operating systems) will be lost. Indeed, this is usually the simplest way to in Linux.

Sorry I'm new to Linux, So when I boot Linux off my USB it installs off the USB ? Then I have a option to get rid of windows? if so that is great, So after I boot it off the USB it installs to my computer so I am able to remove my USB and still be on the Linux OS?

Hi,
If by "Linux" you mean "Linux installer" or "Live Linux system with installer" then yes.

Yes.

Yes, you have that option.

You could be more distro specific. And give us some more details on your proccess :

1. Create a USB boot disk with whatever distro you like
2. Boot your computer -> BIOS -> Boot Priority -> Select the USB device as first boot device
3. Reboot computer and follow the installation proccess.
4. You ll get to a point in which you need to partition your hard drives, this being the point in which you can either Install Linux allongside Windows thus getting a DualBoot option at startup, or erase everything and install Linux as a standalone OS
5. When the bootloader selection screen appears, chose Grub2 or Lilo ( depending on distro ) and set it to boot from MBR (Master Boot Reccord) thus giving you the posibility to boot Linux after restart without the USB plugged in.
6. After you chose whatever is that you need, continue following instruction until the install is finished.
7. Remove the USB and restart.
8. Enjoy

Hope this helps.
Cheers !

I get a error when trying to boot it. It says "Selected boot image did not Authenticate. Press <enter> to continue." What is wrong?

Hi,

that sounds like UEFI secure boot fun. You'll need to disable it (I think). I do not have experience with such technology but there is plenty of information about it on line. Have a search with your favourite search engine and if you can't work it out, start a new thread here on that topic.

If its not a macbook you re installing on, then you should not use UEFI and needs to be disabled from BIOS. Also, make sure theat the md5sum of the image you downloaded is fine and passes the integrity test before burning it to a DVD or booting of a USB stick

Cheers !

Also make sure that the USB disk was formated to FAT32 before making it a bootable instalation disk
