For a while now i have been dualbooting XP and Vista. Only recently, both have stuffed up. XP appears with a loading screen, loads for a few minutes, the screen then flashes off, then on, then off and reboots. Vista: after i try to log in explorer.exe does not load and i get a message saying "Unauthorized change made to windows".

Before this happened, Vista wouldn't let me access regedit, and i scanned it with malwarebytes anti-malware and found a trojan disabling regedit. After deleting that trojan, i would have access to regedit but 5 minutes later the trojan reappeared.


Help please?!

Sounds like vista's infection moved over to xp?

Use safe mode and QM7's post in #2 of this thread with XP to see if you can get a safe mode boot working?

Tried those methods.

Last known good configuration does what XP normally does, with a flash of what i think was the bsod

All safe mode types get up to Mup.sys, and then the screen is on for about 30 seconds before it reboots.


edit: i forgot to mention my cd drive is stuffed and i cant find my vista reinstall disk that came with the laptop.

Would you run xp as a repair disk

Boot to the cd

Then immediately run a quick scan with MBAM

Do not boot into Vista

You need a usb cd/dvd drive or a replacement for your laptop drive

This is why I tell people to limit the use of laptop optical drives and save them for emergencies/necessities like this.

Before doing this, while i was still in safe mode i upgraded to the latest version of a-squared and it found alot of viruses ending in !IK or something. Now is there anyway to repair the startup process for normal booting Vista (eg, running explorer.exe)
