Hi guys I installed ubcd onto a usb ironically to test it. Usb booted ok so i Dissided to load parted magic.files stated loading then hung on loading system files for ages. So I shut the pc down. Now I the pc will not boot normally.i was duel booting 7/8.1 but now when I start I get the post beep like it's going to show the boot menu but just reboots into a continuous loop. Iv used the recovery disk to run some cmd commands to fix boot.also repair windows .no joy!!!another odd thing is its very reluctant to boot from cd/dvd. Sometimes it will boot to win7 if i have the recovery disk in and tap the keyboard key When it should be loading the recovery disk??..really need some ideas.
