Hi, my first post. Plus first time I have had a new win10 system fail with probably a hdd failure, so lots of learning new stuff etc regarding the manipulating EUFI options, GPT options etc. Anyway to cut to the quick, I have an old version of Hirens on flash drive, and the latest version on a disk. I changed the EUFI in the Asus AIO from secure boot, and changed the 1st boot drive as necessary, and was able to boot from the flash/disk. However as soon as control was passed from Eufi to loading win xp in hirens, the power to USB devices was lost, so had no ability to use Hirens. This doesnt happen with traditional BIOS/MBR setups so was wondering what the issue might be and how to fix it; I guess with EUFI/GPT becoming the norm we will need a version of Hirens that works "out-of-the-box" so to speak Anyone got a simple solution to this?
