I created a boot disk using Ubuntu “startup” program to install Linux on other computer, it worked fine, but when I put the USB Flash Drive on my computer that is running Windows 10 it only show 2MB.
It happens because the boot disk has two partitions and Windows only see the FAT partition. Fortuntately I found an way to fix it:
C:\> diskpart DISKPART> list disk DISKPART> select disk 1 (make sure its the right one) DISKPART> clean (if it complains about permission, just type clean again)
It removed the partitions, but now I need to create other partition:
DISKPART> create partition primary
Then after removing and inserting the disk I format it and everything worked fine.
