New laptop with Win7 pre-installed. No Win7 CD. Laptop HDD came with separate recovery partition. Burnt recovery CD and backed up HDD to seperate USB HDD. Then laptop was dropped. Laptop won't boot past blank win7 desktop(with curser). Tried running HP recovery program from recovery CD but program says no recovery partition found and once again, will not boot past blank Win7 desktop. Can't get to chkdsk to run HDD fix. With the Win7 stuff that I have, I can't get to any point where I can even determine if this laptop HDD is fixable? Is there a Win7 iso file that I can download to boot into Win7 so I can then run chkdsk and then access my backup original installation on my USB external HDD? If not, can I use one of my old original Win XP CDs to boot the laptop, run chkdsk or maybe even reformat the drive NTFS, and then install my backup Win7 setup from the external USB HDD over the now XP installed HDD?
