So I'm trying to install a new OS on my ASUS Laptop (Model: TP501U) and it runs the BIOS: Aptio Setup Utility version 201.
For some reason, everytime i try and boot off any sort of USB, the option does not appear underneath "Boot Override", and when i try to go to "Add New Boot Option", I can't find the directory for the USB. This applies for all USBs i use and all ports i use. Can anyone provide insight on the issue here? Thanks.
Have a go at using Plop Linux to see if it's USB boot option will allow the USB boot.
You can do this in a couple of ways including using EasyBCD to add Plop or alternatively burn it to disk (if of course you have a Disk drive) ... by the sound of it you are obviously not going to be able to put Plop on a USB and boot from that so the above seem to be your best options.
Do you have a USB slot with an Orange internal socket ? If so use that one, on some cases / monitors the USB drives wont be recognised during boot. If you dont see any USB slots that look like the port in the link then make sure you are using a USB slot on the back of your case and not the front.
