Corrupt boot loader on /dev/sda. Preparing for LM 17LTS
I borked the Linux Mint 16 install, over a year ago, due to lack of awareness of uEFI and operator error. Windows 8 was completely wiped out and will not be replaced.
Normal boot fails and defaults to the prompt: MBR:__
I managed to get rEFInd installed, but I'm not sure where it is - maybe /dev/sda5.
I recall following instructions to edit some grub files with rEFInd entries, at the time.
I have to press F12 on every boot to see the boot options as presented by rEFInd. Currently installed are LM15 in BIOS/MBR mode and LM16 in uEFI/GPT mode. I want to continue with the uEFI/GPT mode because the BIOS/MBR mode is now aging fast.
I have an updated rEFInd application which is installed alone, on another USB. I seem to have installed on /dev/sda, but not sure where - maybe on /dev/sda2, which was the origianal boot. I reformatted /dev/sda1 but the process wiped out 'volume labels' and only /dev/sda3 and /dev/sda5 show up in the file manager.
How can I fix the boot sequence before installing LM 17 LTS.?
