[Solved]Re-Install Grub without live CD/USB

I'm a dual-boot(2 SSD's: 1 - Windows, 2 - ARCH) user for convenience, I have installed grub with removable tag. However, I had to replace the ssd(where windows is located) all the boot info was also replaced. I'm able boot into arch but every time I need to add it to the boot sequence because that will be stored as volatile memory.

Now questions are:
1) can i reinstall grub without a live cd/usb? if so how?

Re: [Solved]Re-Install Grub without live CD/USB

You normally install GRUB from the actual system when chrooted so you can do that just the same if you're able to boot the system https://wiki.archlinux.org/title/GRUB#UEFI_systems -- exacter details than that vastly depend on how your mainboard handles UEFI entries. Which is it and what does "need to add it to the bootsequence" mean exactly.

What output do you get from

efibootmgr -uv

Re: [Solved]Re-Install Grub without live CD/USB

after running the command you mentioned, i got to know that i had a copy of boot info and i can solve this issue without grub reinstall.

Thanks!
