In this question,the answer said that we can force Ubuntu to install in legacy mode by deleting the EFI
directory tree on the flash drive.
But how can we do this?
I wanted to delete that from flash drive but there is no delete option!
I wanna install 2 Linux OS's in legacy mode,but Ubuntu don't let me do that!
When i choose Legacy mode in Bios,In the first of the installation ubuntu shows error!it says that i most install it in UEFI mode.
ls
output from flash drive:
boot dists install md5sum.txt pool README.diskdefines
casper EFI isolinux pics preseed ubuntu
Note that my laptop has no CD-ROM.

from the Ubuntu iso file to the USB flash drive, a 32-bit version will boot in legacy mode and a 64-bit version will boot both in legacy mode and UEFI mode.
