Windows 7: Windows 7 install refuses to reboot at expanding files

Windows 7 install refuses to reboot at expanding files

So I'm trying to install Windows 7 via XP SP2 but every time I try it gets to the expanding files part(27%) and cancels the whole installation saying Windows could not prepare the computer too boot into the next phase. I ran a chkdsk scan on the drive and unplugged all USB devices and some people said that Windows couldn't find the HDD Controllers so I installed my chipset drivers too but still nothing.
I can't really format these partitions(especially C: since I need the XP installation on it to install Win 7)
What could be cause of this? Can a damaged or missing bootsector(or bootmgr) be to blame?

Try cleaning the HD Drive first.

Hello mate, you need to boot the Windows 7 installer and not run it from the XP desktop.

If for some reason it has to be from the XP desktop, have a look through the information in this tutorial linked below.
Clean Install Windows 7 from the Windows XP Desktop

If there's anything you need to recover from the Hard Disk Drive have a look at the information in this tutorial linked below on how best to copy out that data to external media.
How to Copy & Paste in Recovery Console on Windows 7 or Vista

If not I suggest you run the clean command to over-write the Hard Disk Drive MBR and start the installation again from scratch and be sure to post back with any further questions you may have and to keep us informed.

information   Information

1) To rule out HDD Master Boot Record format errors, boot the Windows 7 installation media to diskpart and run the clean command, it takes only seconds to complete; once the clean finishes, exit diskpart and use the Windows 7 installer to create and format a single 100GB partition for the installation.

If that doesn't work, after another clean, use diskpart to create, format and mark Active a single 100GB partition to see if that works, use Step Two #2 in the SSD/HDD tutorial for reference.

You can always extend the Windows partition to include the remaining unallocated space on the HDD / SSD or create additional Primary partitions or an Extended partition after the installation completes if you choose.

2) If you have ever had Linux installed to the HDD in any way, a simple clean command will not over-write the Grub boot-loader, you must use the full clean all command to completely over-write the Grub loader so Windows will install.
