I tell you your problem. There are 2 types of partition tables that are being used. The normal one we knew a few years ago is MBR. In this type of installation you can put up to 4 partitions per disk. This began to cause problems when manufacturers like Gigabyte used the hard drive of the PC making a hidden partition and putting in it a cache of the BIOS. When you then had 3 partitions, and put the disk in a system with this type of hidden partition, what happened was that you disabled half a disk to use it. Then the GPT system emerged. The GPT system supports many more partitions, hidden and system, imageness mounted recovery and installation. That is what you have. Your pendrive is normally in MBR mode, which when you want to install it, will make if the machine is prepared for UEFI which is the licensed mode in hardware and safe boot, it will not start. The UEFI must be deactivated, the usb as a secondary boot device after the disk, and the option of inherited compatibility or LEGACY OS, activated, some systems also have system selector for windows 7 or 8, this actually allows you to choose between GPT or MBR. In summary, you must deactivate UEFI and secure boot, either you put your pendrive in GPT or you put the equipment for csm or mbr installation. TO ENTER THE BIOS, GPT SYSTEMS HAVE AN AUTHORIZATION FROM SOFTWARE. To authorize you to enter the BIOS, you must go to the upper right corner and lower the cursor, the configuration wheel will appear, and below change the configuration of the PC. In the last option, Update and recover, Recovery. There you have the last option, Advanced Start. Restarts, You choose to troubleshoot, Advanced options. There you will see the UEFI configuration option. Once you restart you will be in the bios. Remember that you must deactivate everything at once, because you will not have another system authorization to enter if you delete windows and the new installation fails.
