this is after the windows 10 update ?
you can try these instructions. they give a bunch of ways to try to get to their repair functions where you can either try the repair or going back to your old windows. sometimes it works. but those are about your only chances if it wont even get to windows. sometimes its so screwed up your only option is to use the computer recovery options to wipe everything out and go back to factory specs.
If this is the first time it has started after the upgrade and you have not done so try just restarting the computer. sometimes that straightens it out
otherwiseIf you can get the windows 10 desktop
right click on the start button and select SETTINGSthen accounts and recoverythat should give you repair options you can try
if you cant get anywhere on the desktop but you can get to the sign in screen
at the sign in screen before you log in there should be a button to restart the computer on the right hand sideif you hold the shift key on the keyboard down while selecting the restart optionit should bring you to a page with some repair options that you can try.
if you can not get the computer to do anything useful at all than you need a boot disk ( actually a flash drive)you can create the flash drive using the program that you download from this pagemake sure that you select the option to create a flash drive for use on other machines
you can put that flash drive in the computer and restart it and it should reboot from the flash drive that will give you some repair options you can try including going back to your original operating system or re installing the windows 10 totally
this post shows all of the options that you can use from the windows boot drive including how to make sure that the computer will actually boot from the flash drive
It won't even go into the bios setup? That's not good at all. That should work no matter what Windows is doing. You can try tapping F8 as it turns on and see if you can get to the advanced options to do a factory recovery
dont think i got all of your reply.
my first post had a link to create a win 10 boot disk from another computer ( actually a flash drive) if you can create that and boot from it you might get some more options.
you can try removing the hard drive to see if that gets you into the bios with F2 but you are going to need the hard drive to install or repair anything either way. it may give you a better idea of whether there is something wrong with the computer hardware or just the operating system though.
i have done my best but there are very limited options in this case. You might even have a hardware problem.
you can email***@******.*** for a refund
