[SOLVED] Grub disappeared from bootloader after removing a partition

I had 2 additional partitions mounted in fstab. I dualbooted windows to delete the one I never used. After restarting to boot back to arch, grub disappeared from the bootloader list - only windows boot manager, arch iso and grub rescue remained.
The boot partition originally was sda6, but a quick check confirmed that it's now sda5, so I guess removing a partition messed up the order? People with similar issues used a live usb to fix grub and I don't have one.

Bud you surely messed up partitioning, if it went from sda6 to sda5 then you did something very wrong, and if you dont understnand how partitioning works, it important to first understand how to partition the system and then try to install it again.

If it was still sda6 and just removed from bootselector then what you would have done is, load live usb > connect to internt > mount root to /mnt > mount boot partition to either /mnt/boot or /mnt/boot/efi (depends on what you have kept earlier) > Re install the grub > exit

but your case is different, its better to start again and keep in mind the partition I would like to help you how I keep it with my dual boot

Keep windows boot partition and linux partition seprate, because windows udpate tends to duck up linux boot partition

I guess the soft I used to delete the partition is to blame.
I made a fresh arch install and used it to mount my original arch partition (which also had its index decremented by 1) to grub.
Solved.
