I have a single HDD with W10 & Zorin 18 PRO installed (last night). Zorin worked, but when I booted W10, that worked, but when I tried to return to Zorin, I ended up in Zorin safe mode. the journalctl showed many failures. in safe mode, findmnt /boot/efi returns a blank. That directory is empty (ls /boot/efi -> nothing).
BTW, Zorin dual boots with the newest System76 POP-OS on another machine.
Though this guide is for 22.04, the steps are the same as for 24.04: https://linuxconfig.org/ubuntu-22-04-boot-repair-how-to-guide
Can you try running Boot repair and relay any errors if it fails?
Only to add that to @Aravisian's Comment: @Herb, when You start Zorin in Live Mode from the USB Stick (choose Try Zorin), there is Boot Repair already available to use it. So, You don't need to install something extra.
Thanks, boot-repair did not find anything to repair. I take it W10 wiped it out in trying to repair itself. The W10 boot menu takes up 30 MB of a 540 MB partition. In addition it said to make a partition under sda6. I will see how it goes.
Update: The install ran into more problems. I decided that I had wasted enough of my time and the time of others who have been trying to help. I overwrote W10 with Zorin18. Thanks for your inputs.
