WINDOWS DUAL BOOT ISSUE HELP

[Mahbub]

so i have two ssds in my system and i had two operating systems.. win 10 and win 7.. at the startup it used to show which one i wanted to boot into... yesterday my windows 10 got corrupted and i had to reinstall the windows 10 from scratch... after which in the boot option dosent show

windows 7 even tho the windows 7 system files are there on my other ssd... i tried msconfig but it dosnt even show there... any way to bring back the windows 7 to life or i need to reinstall windows 7?

Seems to me both W7 and 10 shared the same bootloader on the 10 partition. That's overwritten now. You'll need to add the W7 install to the bootloader again.

 

See if this helps you:
