Unable to Boot from USB

[ohm.patel1]

I have Envy 15-3017tx. I have windows 7 x64 installed from hp. I have c drive of 931 gb and now i shrinked the size 40 gb. I want to install back track on the unused space left after shrinking. I have made bootable pendrive by unetbootin. Now the problem comes. I m unable to boot the pendrive. Option doesn't show up for booting with pendrive. I don't get the option for enabling or disabling usb boot. THough i can set the booting oreder. So i have set the USB boot as the first pendrive. Though i m unable to boot from pendrive. Plz help.

Try manual booting via selecting pen drive from boot devices list. If it fails, your PD is not bootable.

there isn't option for usb boot. only disk and internal boot are the options available.

It has to be there, irrespective of PD is bootable or not.

I have an option of usb diskette which i have set to first preference and another is usb floppy which is disabled and there is no option to enable it. I have tried plop boot manager. But after making live cd it runs. But does not boot from usb, it shows error after disabling driver.

I tried lili usb installer but even this is not working. I finally used 3 rd dvd after wasting 2 and got it burned. I really hate nero now.
