Dear forum pros,
My Dell laptop running Windows XP was recently hit with a ransomware virus - the kind that locks the whole machine and won't allow you to boot to safe mode. My internet research led me to try to repair my machine by running Kaspersky Rescue Disk from a USB. I did this (apparently) successfully by letting the Kaspersky scan everything that was an option (including ticking the check box next to the C: drive) and then after the scan was complete and files had been moved to quaranteen I restarted my computer.
This is where I ran into problems. Booting without the USB now yields a black screen that says "Missing operating system". If I reboot to the Kaspersky USB again I have the same choices to scan and repair but notice that this time the C: drive does not appear in the list of items that can be scanned.
If you can provide any ideas as to how I can recover from this I would appreciate it. Unfortunately I don't have the original Windows disks because the laptop was a work-provided machine that I purchased when I left my last job.
With thanks in advance,
