My friend upgraded her inspiron from windows 7 to windows 10 without checking to see if it was compatible. Now it is stuck in a boot loop and keeps restarting without loading. I purchased the Restore media for this model from dell and it arrived as a usb stick. The computer will not boot from usb. I have set the boot oreder correctly in the bios but still wont work. It will boot from disc. Can i fix this problem or make a bootable disc set from the Dell usb stick?
The first thing I would do is try to boot the USB on another machine. If it boots then you know the issue is isolated to the PC and not a bad USB drive. Also double check the boot order of the USB in the BIOS just in case the settings weren't saved when adjusted.
Usually any Dell Windows 7 image will work to boot your machine. Download one and burn to a CD/DVD as a last resort.
