hi
i was creating a bootable usb of win xp using window 8 64 bit , then suddenly a light blue screen appeared compiling an error report and said that pc will restart. but after it restarted a blank screen with "j" written on the top left appeared and went no further . i checked the bios and it was ok, performed memory and hard disk tests and they also passed . now it doesn't boot from any source and if i select recovery or start normally it gets stuck on the black screen with a "j".
urgently need help
regards
