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 following things to fix the boot:
boot-repairutility, it failed with following error: 'Please enable a repository containing the [grub-efi-amd64-signed] packages'
UEFIpartition and tried installing grub on it manually. It also didn't work.
- logged into windows and tried
easyBCDutility. Here in add new entry option, Linux is disabled.
But neither worked. I cannot login into Ubuntu now. However, I have bootable Ubuntu USB handy with me, my home is mounted on a separate partition.
is there a way to fix the boot loader without losing anydata? If re-install is the only option, If I use re-install ubuntu option instead of "something-else" will it fix the bootloader? Please refer me to the any useful link which I can follow to re-install.
