  • Start up repair tried several times but still cannot determine cause of problem (3 times)
  • Unspecified changes to system configuration might have caused problem,. Repair action – system files integrity, check & repair. Result – failed, error code 0x490, time taken 675827 ms
There are several suggestions on the internet to carry out changes to the registry. Although I have experience of doing this I would prefer a clean fix
Hope someone can help.

Please post back a screenshot of your maximized Disk Management drive map with listings showing all columns, using Snipping Tool in Start Menu. Label what's on all partitions. We will give you the steps to recover Win7 and/or your Dual Boot - do you wish to keep it?

Is this factory preinstalled Win7, with XP added to another partition as a Dual Boot? Do you have Recovery Disks, a Win7 Reinstallation DVD (or access to any Win7 installer), and your XP CD or a backup image of either OS?

I am not able to get into W7 so I cannot use the snipping tool.
As requested I am enclosing a word document providing screen shots of Disks 1 & 2 from Partition Magic (Not compatible with W7) & Mini Tool Partition which I used on a Net book but not used on my W7 system.
For W7, I used Spotmau which has been acquired by another company & no longer recognises my log in ID.
I suspect Spotmau has incorrectly reset the partitions and status, moving the order which was not requested..
The word document provides details of what is on each disk.
Win 7 is not factory pre-installed. I set up a dual boot arrangement using Partition Magic and added Win 7 Win7, naming the new partition "New Simple Volume" as instructed by Windows.
I have done a Recovery Disk with Paragon Backup which does not have the green recovery console so does not work as intended. The screen shot actually displays in the Win 7 recovery system when carrying out the memory check.
I do have the Win 7 installation and the XP CD.
I do have copies of the various drives on external Hard Drives but not completely up to date.
I have uploaded the word document
Thanks for your help

My original word doc was to large for your system. As I am in XP and not win 7 I cannot access Paint so am sending 2 word doc files.
One was again too large so I have sent them again.

The screenshot does not show your Disk Management drive map and listings. Go Start, then rightclick Computer, select Manage, then from the menu Disk management. Maximize and grab screenshot.

I have no idea what Spotmau is but it isn't recommended by anyone here, and Partition Magic is not even compatible with Win7. You may be best advised to boot the Win7 installation DVD to clean reinstall following these steps to get a perfect reinstall: Reinstalling Windows 7. You can copy out your files first from XP.

Other than that best option you can try entering System Recovery Options to run Startup Repair on Win7 installation, which should automate System Restore. If not and you have a Restore point before your log-in program blocked you, I would try that manually from the Options list at boot.

If you want to attempt to repair Win7, then mark it Active in XP DIsk mgmt, reboot into DVD Repair console or Repair CD to run Startup Repair - Run 3 Separate Times until Win7 starts on its own.

This will place the System boot files on Win7 partition which should now be marked System Active.

To add XP, install EasyBCD to Win7 to add XP from its Add OS Entry tab, Save, reboot to Dual Boot menu. Earlier versions of EasyBCD are still free.

If you want XP to remain holding the Win7 System boot files as it does now, then it needs to be marked Active when running Win7 Startup Repair from DVD Repair console or Repair CD, to see if Win7 will repair itself while saving the dual boot. Partition - Mark as Active It is less likely to succeed this way, so you may be better off marking Win7 active to let it reclaim its own boot files and repair itself, then add XP to Dual Boot from Win7 desktop using EasyBCD.

If you have complications with a log-in program that is blocking your log in you may want to consider reinstalling Win7 to its partition, which should autoconfigure the Dual Boot during install - if not install Easy to Win7 to add XP as given.

Thanks for your help.
I did the checks as suggested, results were :-
In XP disk manager –
Disk 0 - Local Disk 1 XP (D) was Healthy (System, Page file, active, primary partition).Local Disk New Simple Volume (E) Healthy (Logical drive).
Disk1 – Local disk 2 (C) was Healthy (Boot Crash Dump, logical drive), Local Disk 2 Other Captures (F) was Healthy (logical drive)

Disc manager did not allow me to set any partition changes, so Using Easeus Partition Master the information for Disk O was confirmed & after backing up my system changed “Local disk, simple volume” to primary & active & re-booted system.
Repair console was run 3 times and I ended up with error “NTLDR missing” message (as after original crash).
Rebooted with the O/S disk twice, before system booted into windows repair.
Widows 7 loaded (apparently in(C) local Disk 1 XP) and all looked OK although as expected with my programmes.
I then tried to boot from “Earlier Version of Widows” (XP) which failed.
8/11/11 transferred back up files & folders and up to 12/11/1. have updated about 75% of them
Windows requested Re-activation of win 7, 14/11/11 successfully completed.
16/11/11 successful boot into windows XP without using Easy BCD, suggesting I have a dual boot system again.
Re-booting into Win7, Viewing the partition map I note that Disk 1MBR Local Disk 1 XP is now disk “Z”,I have enclosed the screen shots.
Now that I can now use Win7 & XP normally, Could you advise me how to change Disk 1 XP from z to c ?
Windows Boot Manager –
On Start up I have 4 Windows Boot Manager “Start Up” Boot instructions –

1. Earlier Version of Widows (XP) 2. Windows 7 (fails to boot & goes back to boot manager)
3. Windows 7 Home Premium (recovered) currently used
4. Windows Vista (TM) Home Premium Recovered which I do not use

How can I remove the 2 unwanted boot instructions at 2 and 4 ?
How can I set disk number 1 MBR Local disk 1 XP to the same label - “C” in Win 7 & XP?
Can I merge the partitions marked * with “F” New Volume?
Once I have completed the clean up, what would be the best way to transfer Disk 1MBR to a new 1 TB HDD?
Once again, thanks for your help, much appreciated

Why are the screenshots requested appearing in .doc format so those without Office can't read them for you?

If you use the Snipping tool in Start Menu and save the file in its default jpeg format, it attaches to your reply post perfectly without creating the extra layer of trouble.

You cannot mark Active to write the System boot files to Win7 so that it boots on its own without using the XP bootloader because it is Logical. Use free Partition Wizard bootable CD to rightclick>convert Win7 partition to Primary, then rightclick Win7 to Modify>Set it Active, highlight it's HD then from the Disk tab select Rebuild MBR, Apply all steps, reboot to see if that suffices to boot Win7 on its own. If not, boot into the DVD Repair console or Repair CD to run Startup Repair up to 3 separate times with reboots.

I would unplug the XP HD to do these repairs, swapping it's cable to Win7 so that it is in Disk0 slot, making sure it remains set to boot first in BIOS setup.

Once WIn7 starts on its own and is flagged System Active, plug back in XP and boot it using the one-time BIOS Boot Menu key when needed. If it renders a BOot Menu, use EasyBCD 2.0 to Edit BOot Menu, deleting all but the XP choice.

This keeps the HD's independent booted via the BIOS so they can come and go as you please, reduces complications to nil, and avoids having to do surgery if you want to remove one HD later.

Windows XP & Win7 are on the same HD (LocalDisk 1) but in different partitions. Pulling the cable from Disk 2 would not allow me to boot into 7 on it's own..
