Prob. with Norton GoBack & boot error

Wondered if anyone might offer a little tech support please?
A mate at work asked me to look at his PC as it wasnt booting up any more. Its a P4 Dell (no longer in warranty) with WinXP Home (dont know if SP1 or 2) which he'd stuck Norton GoBack on.
His son has been turning the PC on and off at the wall (but not going through Start -> shutdown) and there has now developed an error in the boot process. I have tried my basic abilities to repair via the WinXP install disc, to no avail.
When i add the hard drive to my own PC it doesnt mount in windows, and Partition Manager shows a "Type 44" partition (after a 7MB first partition) which google shows to be related to GoBack. It also means the data on it is not accessible to me.

I seem to be a catch 22 - i can only access the data by booting from the hard drive, but the boot process is knackered. My friend does not want me to format the drive yet as he hasnt backed up important data :Oops:

Any ideas? I dont have the original GoBack disc (but can probably get it) and wondered if I could boot off that?

Cheers in advance

Just to finish this thread in case anyone in the future does a search, it is sorted.
Symantec has in their support area a downloadable ISO that you can boot from and disable Norton GoBack. From that point I was able to fix the windows installation and get it all working again.
Bloody symantec - they are getting as bad as McAffee wanting to control your whole system.

GoBack has a lot of install problems. A pity, because it works better than System Restore in that it EXACTLY restores to a former state - then gives you the option to retain critical files changed in the interim.
Here's what to do if you have problems installing or reinstalling Goback (and SystemWorks 2006 Premier)
1) Use the Norton Removal tool to remove traces of previous Norton stuff (You can download it from Symantec)
2) Delete the Symantec Shared folder from Program Files/ Common Files
3) Reinstall SystemWorks.
If you get the blue screen of death and "Session Manager Init System process terminated" you should reboot and hit the spacebar on the GoBack splash screen. Then choose the option to disable GoBack. Alternatively, press CTRL ALT G repeatedly throughout bootup and choose option F to delete GoBack.
If you get into a reboot loop at the User logon screen of Win XP, you can get out of this by rebooting in safe mode (F8) and going to Services in Settings - Control Panel - Admin Tools. Then right click on various Norton and Symantec Services to bring up their properties and set any that are automatic to "manual" (Specifically, the services most likely to be causing problems are Symantec Event Manager and Symantec Settings Manager - the others can usually stay "automatic"). Then restart and you should boot up normally.
After all this, can you reinstall SystemWorks 2006 Premier in such a way that all functions work? I'm afraid I still haven't cracked that one!
