My PC has Win10/Win7 installed with dual boot. I will be presented with a selection menu where I can select whether to boot Win10 or Win7.
I have my Win7 installed on Disk 0 (C Drive) and Win10 on Disk 2 (J Drive). But I lost my Win10 password (That's stupid - I know) and I couldn't login back to Win10.
There is nothing serious yet on the Win10 system. So I thought I can just reboot the PC and reinstall Win10 with the DVD.
Things get complicated when I read the options from the installation disk which I am not so sure if the installation will touch my Win7 installation (It shouldn't because that's how I install Win10 in the first place - anyway, doesn't matter anymore). So, instead of proceeding with the normal repair/reinstall option provided by Win10. I have reformatted Disk 2 (Drive J) and restart the computer.
I was expecting the Win10 start up disk will take this as another fresh installation. However, it is smart enough to know it was not. I got a start up error message but I can proceed to boot with Win7 so it is not the end of the world yet.
Any thoughts on how to re-install the Win10?
I am able to reinstall a new Win10 just to give up the original boot menu. The newly installed Win10 got its own boot menu. I can still able to access my Win 7 by changing the boot sequence in BIOS every time if I want to. It is annoying but not the end of the world though.
I suppose I can work something out using bootcfg command later
