restore from image HDD size changed

[Maxheadroom]

ive done an image restore using Acronis, the original HDD size that ive taken the image from was 69GB with about 30 gig of info on there, the drive ive copyed the image to is 150gb but after copying the image too it the drive now shows as being 69GB.
so i guess its partitioned that drive and the space isnt being shown.
how do i now resize the the disc to its original size? and can i do this without 3rd party software?
thanks

Use Disk Management within Windows 7. The remaining space will probably show as "unallocated". You should be able to extend the 69 GB partition to include all the unallocated space.
