So i have dual boot on my notebok DELL INSPIRON N5110 and i get a blue screen of death on win8, so my os wont load and i tryed to boot from usb but when i put my usb win8 instalation menu opens and then sudently restarts and it goes over and over what to do ............... ?
hard to say what the issue is. Need the bluescreen codes.
A restart while running your USB win8 install to repair is not good. It would generally indicate a hardware issue/failure maybe in Power, or over heating caused by a fan. Sometimes a missing driver for some hardware. (maybe turn off special hardware features in BIOS) Hard to say.
I don't know about your machine but if you have a removable battery I would pull it and run on AC power then try to boot to your USB thumb drive. (try a different USB port might help, many systems have 2 USB controllers)
