A foolish choice

I have 2 partitions in one HDD that both have windows installed (dual booted), one for me and my younger brother. Earlier, I tried to rename his Windows folder (the one on the root) and I thought it will remove the dual boot and go straight to my OS.

But to my surprise, I can't boot to my OS either. Where did I go wrong? HELP!

Rename it back to Windows?

@asgs I kinda did that, but the boot option is still not showing.

@theKarlisK hmm thanks for the tip but I already tried to reinstall a fresh one with another HDD and backup my files. The reason why I renamed the Windows folder is too try and see if it can be removed from the dual boot screen on startup. I'm trying to install 2 Windows OS an 1 on the other one to see if I can choose 1 of those 3 OS' but I think I'll still need to rely on GRUB anyway if I want multiboots to work. D*mn this is so hard. Also can you give me a good tutorial for GRUB installation? I'm not yet familiar with bash kind of installation (like what linux systems had) I only encounter GRUB when I install Ubuntu 16.04 so it'll be a big help if you have link for one 😁

Why do you need multiple windows on same PC? 😶

@cursee I'm trying out things and I preferred not seeing my brother's account on my partition. He tends to install stuff and play his games with admin rights. Will cry if I don't give him the admin rights cause he can't play his ripped off PUBG game (ROS) or LoL.

God I need this to work.
