So I decided to do a reset on my 17 R2 yesterday and it kept giving me the inaccessible_boot_device error in the BSOD. I've been running Windows 10 with no issues before the reset but after it had reached 100% its in a constant boot loop till the battery dies out. It does however have the loading part with the little white balls going in a circular motion. I decided to do a reset since I thought I had malicious software in it. I've read on a few other forums that the only way to reset it again in this error is to use the USB thingy which I don't have or its to spam F8 which also doesn't work.
