It would not do the install using UEFI at all. I did a clean install, but before I could do the install, I had no choice but to change the bios to "Legacy". I never changed the drive settings "after" Windows was installed. For that there is a post here they may help http //questions/389971/how-to-move-an-existing-installation-of-window-7-64bit-to-uefi-from-legacy There are some work arounds that you can try http /but they deal with ATA vs AHCI mode and not UEFI vs Legacy. Change drive options to what they were and Windows will boot again. Where are the experts that have answers?Īnswer is "don't change drive setting after Windows is installed or you need to do a clean Windows setup again on the new setting". Hang-the-9 tells us what we can't do, but fails to tell us what we can do. They are all recommending that you switch your bios to "legacy" and it solves the problem. All of the recommendations that I am seeing online are all from novices that don't know any more than I do. System type: 64-bit OS, 圆4-based processor Everything works on legacy BIOS, though.Īny help is appreciated, but I would prefer if the explanations could be simplified as much as possible since I'm no tech savvy haha. The problem is, after a few restarts, I tried to change back to using UEFI for faster start-ups, but everytime I change back, it says "No bootable device" with the hard drive image above it.
Earlier today I cleaned my drive 0 to do a clean install of Windows 10 using a USB drive however, in order to do so I needed to change UEFI to Legacy in the boot menu and put USB HDD(?) at the top of the boot priority list.
