I ended up using Dell recovery to rebuild my system. I used the "not save" files option and let it run. I believe I should create a boot able usb with the Windows 10 on it. I did get the Bios to read the drive, but the drive would not boot up to the point to install Windows 10. I thank you all for your help on this. I'm back up with Windows 10, it did not fix my problem with 100% disk usage which is what started this whole adventure. I will open new thread on this problem for help.
Have a 7773 using UEFI, bios. I can't find anything that helps me get the boot sequence or F12 to see USB. Tried turning off secure boot and turning it back on. Nothing changes. Does not see or list the drive in boot up menu. Any help would be greatly appreciated. Need to clean install Windows 10 from 11. It's been 3 months since it was upgraded. System very slow. Want to go back to !0 for now since laptop not in list to support 11.
