Hello and welcome to to thr winfows7forums

Was this a "clean" install or an upgrade.

Do you have achoice using the Student disk?

i brought the digital version online and then burnt the iso onto a dvd and when i try to boot it i just get a flashing underscore on a black background

I would recommend you re-burn the ISO at it;s slowest speed,. and use a good quality name-brand DVD.

I use Imgburn,

You can download it here:

The Official ImgBurn Website

ill give it another go and see what happens, cheers for your help ill let u know in a bit

If you can't get it to work after reburning, you may have a bad download. The .iso does say it is bootable, right and you did burn it as an image? What utility did you use to burn the .iso?

ive been using imgburn for putting the img onto the disc, tried reburning and it still didnt work just get a blinking underscore, must be bootable as when i put the DVD in and click setup it says not compatible with this version of windows because im uprading from 32 to 64bit. i guess the only thing it can be is a bad download?

Please describe what utility you are using to burn the DVD and what steps your are taking.

You might also try changing your media in case you have one that isn't capable.

the utility ive been using is imgburn and ive opened it up and then click write image to disc...

Did it verify the image?
