Solved XP Boot loop after malware

Specs: Windows 7
Hello

I have an Acer Aspire 5715z laptop running XP.
Upon downloading possible malware, the laptop was prompting me to insert credit details for an anti-malware software, which I knew was fake. This restarted my system and now every boot leads to the advanced boot menu, with options such as Safe mode, Safe with networking, Last known configuration etc etc...

No matter what option I select, the Windows logo shows and then quickly shows a 'Blue Screen Of Death error message/number"

I have tried to boot from disk (XP/Windows7 installation disks) but it simply wont allow me to.

I have tried searching for a "Don't reboot on error" in BIOS but can't find anything. I'm sure buying a new hard drive and installing a fresh OS would work, but is there any alternative?

Could I remove the hard drive from the laptop, connect it to my personal computer and format it that way?

Kind regards

I have tried searching for a "Don't reboot on error" in BIOS but can't find anything.

That option is not found in BIOS. Before the 'Windows loading' screen appears, press F8 to enter Advanced Boot Menu. Select 'Disable auto restart on system failure', and write down the error code that appears.

What happens when you try to do so?

Thank you for your reply.

The F8 function did indeed bring up that option, which I deselected and the stop error was then viewable. This was a "stop:0x0000007b inaccessible boot device".

Nothing happens when I try to load from disk. It simply allows the same routine of attempting to load Windows and take me straight to the BSoD.

Anyway, since then I have gone into BIOS and disabled AHCI, so now it was on IDE.

This now loads Windows, and I have since performed a System Restore and completed a full scan with MalwareBytes and removed many an infected file. Now the system is running well, but if I go back into BIOS and enable the AHCI instead of the IDE, then it gives the BSoD screen again.

So it's now working but not on AHCI. Should I seek to sort this?

Kind regards

Try this. Disable AHCI and boot from the Win XP disk. Then on the first screen, press R to enter the Recovery Console. Then follow these instructions:

Click me!

Note: If you can do the above with AHCI enabled, then it might be better to do so.

"I have tried to boot from disk (XP/Windows7 installation disks) but it simply wont allow me to."

This part of the boot process is almost entirely the bios boot order. If that fails then we need to look at component failure. Try to see if you can get memtest to work. Might have to try a usb cd rom drive to test to see if the drive and controller are OK.

Windows7 ought to still boot to a system that supports ahci.

Be sure there is no recovery partition too.

How did you get windows on it originally? Did you ever change the hard drive?

Kinda missed this part. Please make sure that DVD-ROM is the 1st device in the boot order in BIOS. HD problems should not prevent you from booting the CD.
