Window update destoryed my computer - Microsoft Community

last week mar 20, computer told me had restart computer update device (a 4 yr old dell xps 8500 had win 8 on it) , when did installed windows 10 updates , rebooted.  when came 1 of hard drives missing file manager.  i thought best thing turn off , reboot it.  when did came black screen , message "start pxe on ipv4".  i researched (with computer) , found boot order problem.  i went bios (many times) , reset boot order never change altho drives did show in bios boot order.  i tried boot bios, tried using f12 key supposed change boot order...nothing worked.  the next day called dell service (big mistake!) , on phone on 2 hours, , had me tapping keys bios, tried changing something, restarted it, , trying boot again. time hard drives not showing in bios order.  of course nothing worked , during 1 of numerous tries changes in bios, monitor stopped working!  the dell tech told me without monitor couldn't , have find locally , hung on me!

so have computer won't boot, monitor won't work (i tried on computer , worked perfectly) i'm dead in water, can't computer, it's trashed , bad window update!   have suggestions?

ok, if have graphics card in your dell xps 8500, remove motherboard , try plugging monitor graphics output on motherboard see if can monitor working

then if can see doing, please complete following:

press f12 , run dell diagnostics check hardware

press f2 go bios , click restore defaults

go boot options in bios , disable pxe boot

in boot options move primary hard drive top of boot order

save bios settings , reboot

if system still not start, press f2 bios

change sata mode, if set ahci, change or vice versa

save changes , see if system boots
