NO - that is not the problem. I've tried to explain that to you. Fedora resides 100% on the disk - nowhere else. IF A/ your BIOS supports thumb-drive boots and B/ BIOS correctly configured to boot the USB and if C/ the USB content is bootable - then the disk is never accessed. It makes no difference what is on the disk (fedora, windows, nothing) if your BIOS supports a thumb-drive boot and if you correctly set up the BIOS and the USB.
on my laptop so I dont know how i would "disconnect the HD"
I didn't know it was a laptop. Some laptops you can pull the disk
That was just a suggestion so you can prove to yourself that the problem has ZERO to do with Fedora.
My strong hunch is that either you need to diddle your BIOS settings to boot the USB (thumb drive?) or else your laptop BIOS may be unable to to boot USB thumb drives.
I tried using the USB on my other laptop and it "booted from the thumb drive" successfully. But whenever i plug my thumb drive into my computer with Fedora on it, i set it to boot from USB, but it never does, just skips straight to loading from the computers hard drive not the usb
See my list above. The fact that your USB is bootable on another system
means that item 'C/' is correct.
It does NOT mean that you have correctly configured your laptop BIOS and it does not mean your laptop BIOS can ever boot a USB (containing that sort of image). You may be forced to burn a CD.
So there are two or three questions here.
1/ Please show your laptop make & model.
2/ Please describe in detail the BIOS setting you used to select the USB thumb drive.
3/ Please point to the Mint download you used (and any instructions) to create the USB.
Did you look in the laptop BIOS for USB setting for boot ?
