Disk 1 Partition1: UserData 500.0 GB 466.0 GB System
Disk 1 Partition2: ProgFiles 500.0 GB 409.8 GB Primary
Disk 1 Partition3: Backup 397.3 GB 21.1 GB Primary

There are now 2 System partitions. I presume I need to change that?

and when I do a Dir of each drive I have found that
C: nothing found and no size info
D: 500GB free
E: 5GB free
F: 440GB free
G: 22GB free

So E: = Disk 0 part 2
D: = Disk 1 part 1
F: = Disk 1 part 2
G: = Disk 1 part 3

Early start at work tomorrow so I'm off for a while now.
Disk0 partition 1 should be the system reserved .
Disk0 partition 2 should be the traditional C drive.

Remove disk 1 . Mark Disk0 partition 1 as active and run startup repair for 3 times.

If by the third attempt Startup Repair does not start Win7 then boot free Partition Wizard to run the Rebuild MBR step given in Troubleshooting Windows 7 Failure to Boot .

If possible post back a camera snap of the PW drive map and listings.

I removed drive 1, made disk0 partition 1 the active partition and ran startup repair 3 times.

The first time ran for 5+ minutes but could not repair the disk.
I rebooted and ran a 2nd time. This ran for about 20 seconds and said it could detect a problem.
I rebooted and ran a 3rd time. This also ran for about 20 seconds and said it could detect a problem.

I burnt the partition wizard ISO to a CD and rebooted the PC from that CD. The menu screen to boot from CD or local came up and I choose to boot from CD.
A whole stack of text came up starting with
Loading /boot/bzImage
and eventually stopped at:
"[<c0a19046>] kernel_thread_helper+0x6/0x10
and then stopped there. It has been there for at east 5 minutes now so I guess it's not going to boot partition wizard.

I tried this at least 3 times with the same result each time.

Hi Ian,

The above text is correct and indicates PW is attempting to boot. The later kernel message is a problem as you saw. I'm not sure this will fix the issue, but can you try and burn another CD/DVD but at a slower 4x speeds, and see if that works?

I tried this CD in another PC and it worked fine - booted all the way up to the Partition Wizard menu.

I will try burning a new one at a lower speed.

Hi Ian,

Thats OK - that indicates the CD was burn't correctly, there is no need for another burn. Can you humour me and "burn" the ISO to a bootable USB thumb drive instead, and then try and boot off that if your BIOS has th option to boot from a USB HDD? I'm trying to rule out an issue with the CD drive, although I admit I'm taking a stab in the dark here.

Use this tool to create a bootable USB drive:

Universal USB Installer – Easy as 1 2 3 | USB Pen Drive Linux

Allright - I'll give this a try.
I have already burnt a DVD instead and had exactly the same problem.

Ian I guess you should opt for a clean install. You have tried a lot, a clean install will take much less time and effort.

None of your user data will be lost . Follow the tutorial Copy & Paste - in Windows Recovery Console to move all data out of the drive you will format clean (disk0) to the other one (disk1). Then go to a clean install as described in Clean Install Windows 7 .

For detailed way to get a factory OEM installation, follow Clean Reinstall - Factory OEM Windows 7 .


If anyhow the disk management window could be seen, there will not be so much troubles.

Thanks everyone.
I tried creating a bootable USB but I'm not sure that it worked.
I had to pick a linux distro for the install so I choose the very last one in the list and picked the pwhe7 iso however I can't get the PC to boot from it. The PC has options for all sorts of USB devices but not just a plain USB and none of the options I tried got me anywhere.

I'll give the clean install a try. Stay tuned for more questions as I work my way through that tomorrow night.

Thanks everyone.
