I'd appreciate help with this problem.
I'm trying to fix this laptop for a friend. I didn't set it up in the first place and I personally still use xp pro x32 so I'm not fully up to speed with win 7.
The beast, hereinafter called 'it' has started going into infinite boot ups and trying various fixes (including restoring the hives) have been unsuccessful and the original hives put back. It was originally a Vista OS and was upgraded to Windows 7. Before it went sick, AVG10 reported trojan.Redbrowser. Despite providing instructions to remove, my friend reported that the trojan had stopped doing whatever it was it did. (Hmm, I don't think so) Anyway a few days later AVG10 apparently disappeared and stopped scanning. The infinite reboot started and 'it' is now in my hands.
Won't boot 'Last known good ...'
Won't boot in safe mode
Won't boot to safe mode command prompt
Tried system repair (auto) - both from it and from Windows 7 cd - same result
2-iterations get me to login screen, leaving alone or logging in. Same result - reboot
Using recovery options - system restore - attempting repairs gives unknown Bugcheck f4 params 0x3, 0x84c81c48, 0x84c81db4, 0x8201bd60
clicking finish gives a reboot but cancel gets me to 'choose a recovery tool'
Using system restore gives unsuccessful - failed to extract file C:\windows\$NtUninstallKB4693$\2015401354\click.tlb from restore point.
There are 3-other System Image restore points in Backups , but get message 'selected backup not found'. The backup sets are on another partition on same disk and can be seen from command prompt provided in the recovery options but I can't find a way to tell 'it' to look there.
I've tried both rstrui and wbadmin from the command prompt but still can't get them to see the backups - just 'not found' errors.
From a point of view of self education, I'd like to resolve this one but my other options raise questions i.e.
Does anyone think a re-install from the upgrade disks will work?
If not then I would need to flatten and start again. That's ok but then I wouldn't have Vista to upgrade from.
I can get a loan of full version Windows 7 cd but would I be able to use the original upgrade licence key?
Haven't tried bootrec options yet as I'd appreciate some advice before going further
Thanks in hope
