Well now its my turn to see what the Linux community of Bleeping Computer can do to help solve this problem!
As the title states, I am trying to boot from a USB flash drive on my new Sager NP8258 laptop. I have had absolutely zero luck on getting the thing to boot off the flash drive. I had decided to buy it without a disc drive (who needs one anymore) to give me more HDD storage space. Fortunately I have a couple old laptops so I was able to get things installed with a CD/DVD drive from an old Toshiba... Its just annoying to have to take out the storage bay and pop in the CD/DVD drive when I want to install Linux.
Okay so, I have done the following things (hopefully I remembered them all).
Secure boot is off.
Disabled UEFI boot, though I have tried booting with UEFI on and from inside windows (hold shift and restart the machine brings you to the menu option to do so), this does nothing as well.
Brought up the boot option menu at bios start by hitting "F7", chose my USB drive... boots directly into the Linux OS I have installed at the moment.
Created the Linux boot drive with Unetbootin, pendrive, Ubuntu USB installer... maybe another one that I can't remember right now.
Formatted it to FAT32.
Deleted the U3 software (its a sandisk....).
I think that is all... might have tried some other things but to no avail either. There isn't a whole lot out there about this laptop so I haven't found anything searching the web (Sager laptops are built off the Clevo machines, for background info).
If anybody has any ideas to try let me know! Would be nice to get this working. I did get Windows on a USB stick to boot, though I haven't tried that stick yet for Linux so I'll probably do that next as well.
Oh and it may take a bit of time for me to try the things you all post. After I get off work I usually work out and by then its semi late and I am not always in the mood to try and fix things... lol.
