Windows 7 Professional (x64) will not boot successfully

It would appear (although unable to confirm for sure) that following a windows update, Windows 7 Pro (running on Sony Vaio laptop) is unable to boot successfully. The boot process starts normally, I see the words 'windows 7 Professional' on a blue background (This is not a BSOD) but that's it. The screen flickers (like a refresh) but that's it. CTRL-Alt Del does not work at this point.
I have tried the following:
1) Full AV scan from a boot disk - no viruses found
2) Using a recovery boot disk to start 'System Restore'. System restore fails - I've tried 3 different restore points
3) SFC /scannow - No issues found
4) CHKDSK /F - No issues found
5) Unable to boot into Safe mode - Same symptoms - blue background with screen flicker
6) Start-up repair - Ran 3 times - problem still exists
7) Memory test - No issues found
8) Sony Hard Drive diagnostics - No issues found
9) Last known good config does not correct the issue
10) Booted into reduced resolution - Same symptoms - blue background with screen flicker
11) No BSOD witnessed

Other than a complete format/restore, what other options are available to identify and correct the cause?

I guess you know of tests / fixes available on UBCD (worth a try)

Looks like a corrupted OS
Recover from the recovery discs or Fresh install

Thanks for your prompt responses.
Regarding KB3097877 - Please could you suggest a way of removing the update if I'm not able to use safe mode etc?.
Regards
you can try rdp'ing into the computer and then removing the update if you don't have wsus set up
also try getting to safe mode with command prompt and run
wusa /uninstall /kb:3097877

Thanks for your prompt response.
Unable to RDP or boot into safe mode with command prompt. I can ping the ip address of the problematic laptop from another machine. Tried to connect using psexec but unable to. Any ideas.

managed to boot from Windows DaRT to a command prompt. Ran 'wusa /uninstall /kb:3097877' but system returned 'Installer encountered an error : 0x8000ffff - catastrophic failure'
if you are booting into dart, use the hotfix uninstall tool

Hi - KB3097877 is not listed in the hotfix uninstall tool. Does this mean that it's not installed?

Fantastic support - thank you for all of your help.

Problem resolved by removing KB3097877. The only tweak made to your suggestion was as follows:

dism /image:d: /get-packages

dism /image:d: /remove-package /PackageName: package name goes here

This is because the '/online' option doesn't seem to work when running off Windows PE
