boot options disappear after installing windows in UEFI mode?

I have ubuntu 19.10 on my system with the Legacy boot. I installed Windows 10 in UEFI mode and now boot options are missing at the startup.

I tried the following approaches to fix the bootloader so far:

tried boot-repair utility, it failed with following error: 'Please enable a repository containing the [grub-efi-amd64-signed] packages'

created UEFI partition and tried installing grub on it manually. It also didn't work.

logged into windows and tried easyBCD utility. Here in add new entry option, Linux is disabled.

But neither worked. I cannot log in to Ubuntu now. However, I have bootable Ubuntu USB handy with me, /home is on a separate partition.

is there a way to fix the boot loader without losing any data?
If re-install is the only option, If I use the re-install ubuntu option instead of "something-else" will it fix the bootloader?

You have to use the 19.10 live image when you use BootRepair to fix 19.10.

I've also seen this on Ubuntu when people use a live disk of a different version to be repaired. Also, many people have reported this error with the using the Boot Repair disk on other distros. The thing is, Boot Repair complains about the missing repo of the installed version, not the version of the live image.
