It couldn't start first boot menu

Hi. I have an Asus t100ta 32 GB /2gb ram/ Intel atom/ touchable 2in 1 pc. It has worked with win 10 32 bit until now but storage space is not enough for win 10. I made a zorin os lite usb stick according steps. When I restarted pc and pressed boot button usb stick didn't work. Secure mode is disabled. Pleas help me

Another T100 user @hunggnuh85 foud this useful to fix a sound problem. I assume it is a similar machine to yours, but not familiar myself. Note Zorin15 is based on Ubuntu 18.04 so you should be able to substitute Zorin for Ubuntu where mentioned. Maybe it will jelp you. linux-asus-t100/ at master · 5bentz/linux-asus-t100 · GitHub

Your computer has a 32-bit EFI system so you will need to add the bootia32.efi file to the USB flash drive as indicated in the instructions in the link that zabadabadoo provided. That will be the key to booting your system.
