I've tried all of the suggestions I could find from forums and Q&A sites (like this one), but I am still not able to live boot Ubuntu 14.04 from USB.
I am using a SanDisk Cruzer 32GB.
I have tried:
- Reformatting as FAT32
- Wiping and rebuilding the MBR
- Using several different tools including unetbootin and the built-in live USB creator
- Checking boot flags
- Recreating the partition table
Yes, my BIOS recognizes the drive. Yes, this drive can be booted from.
I have made a bootable USB drive at least 20 times in the past with the same drive without a problem. Any Ideas?
