Dual Boot
gordoncanada you could open setup from the operating system which is working and then format the drives with infected operating system and install Windows on it. You may also try run reset on the infected system so it is like do clean install on that system.
However, I am curious about the virus, normally we could remove all malwares and if it is undetected malware, you could submit sample to Microsoft for investigation. It is always good idea to do some investigation on malware and submit samples of it , before format the system.
Thanks for your reply. I just tried booting into the infected operating system and it won't even complete the boot process anymore. The damage done by the virus, which I wrote down but can't find, something like CLdownloader!74, grows worse all the time. I'm afraid it may make the whole system unstable if I try to boot into it again. Should I delete the OS entry using Easy BCD before formatting the infected hard drive?
gordoncanada you may boot into the system which is clean and update Windows Defender and right click on the infected partition and run scan on it.
You may use bootable Windows 10 installer and perform installation and in the setup select repair on the system which has problem or try format and reinstall Windows on it. However, during installation make sure you select the correct partition to avoid removing the working Windows.
Thanks everyone. I was able to install Windows 10 and maintain my dual boot system. I'm not sure why, but I only have a legacy black and white boot menu rather than the colourful boot menu usually associated with Windows 10 (this happened when I upgraded to Windows 10 from Windows 7 years ago), but hey nothing's perfect.
Thanks again, Gord
