having a problem booting Ubuntu from my drive. I didn't use the hdd in the end used a flash drive, 16GB. Mainly just want to try a few diff distribution before making a permanent decision. So I used the pendrive linux load on okay, but my laptop still wont boot from usb. I change the bios setting to boot from drive first, dose not seem to be detecting it. So is my only other option is to use grub from the drive with the Ubuntu correct or not?
