have another laptop. From there made USB bootable. But i do not make any changes in drop down for rufus, once i select the ISO file it chooses the option itself and i let them as is and click on start. I am currently trying with Zotac USB maker and gives option " Do you want EFI Compatibility mode". I have made one USB bootable (8GB) clicking no for EFI Compatibility mode. and have another USB 32gb (which i think is not working, faulty) and if i choose EFI Compatibility mode in that , it is giving error critical error when formating. and error with rufus as well (so i think pen drive is faulty). Should i be able to do with 8GB pen drive without EFI?
