Problem booting from USB Flash drive

Hello

I was trying to set up my Dell BIOS to Run LinuX from
a USB Flash drive. Would not Boot. Very New BIOS .
Went into BIOS found no boot from USB option.
I had booted from this Flash drive before.
What can I try next ? Geo
Thanks

What format is the drive? I don’t think BIOSs recognize the .ext formats. All my bootable flash drives are FAT formatted.

What Linux system you trying to boot?
