@Tasurinchi I'm on a mac so the pendrive linux software won't work. I've tried in the past downloading and running unetbootin software which is similar to pendrive. I'm giving that unetbootin software a go again but this time I've already downloaded the Ubuntu Iso image.
No luck unfortunately after preparing a usb drive with unetbootin ubuntu. The USB flash drive doesn't even show up in the boot list when I hit f12 at startup.
I've literally gone through all the options in the BIOS looking for some improper setting. Config > USB is enabled. I'm using BIOS Version 1.67 (1UETB7WW)
@realblackstuff I believe so. Here is an image of the usb cable that came with the liteon external dvd drive.

The smaller cable plugs into the drive and the two normal sized usb ports can go to the x40 . I've even tried hooking up one normal usb port to the x40 and the other one to the macbook pro for power.
When I hookup the USB port that is the furthest away from the other two the macbook pro won't power the cd/dvd drive. But when I use the normal usb port that is closest to the microusb port it gets enough power to turn on when hooked up to the macbook pro.
I've tried using both normal usb ports but no green blinking light comes on at all from the liteon external usb cd/dvd drive. When the x40 turns on it doesn't even appear to be kickstarting the usb cd/dvd drive or the usb flash drive due to the fact that I see no blinking green lights on either devices.
I can't for the life of me figure out if 1) the usb ports are broken 2) something in the bios isn't configured properly (even though I've double checked this) 3) the x40 doesn't give enough power to an external cd/dvd or usb flash drive... But then why are other people able to boot from their external drives with their usb ports..? I'm starting to think maybe both usb ports are broken?? I've never ran into this much difficulty installing an OS. I'm almost wishing I just brought a new cheap computer because of how much a headache this is becoming from futzing with everything when it should be working imo.
if you have any other ideas or suggestions please let me know!!
After doing some more research through google i've found

USB 2.0 connector ports
Note: The ThinkPad X40 system has a supplemental power port for USB devices
Then I found this thread

apparently on the left side of the thinkpad there is a supplemental power port.
