Thanks for the offer, Michael, but let me clear a few things up first. |
| 9 |
|
| 10 |
1. I don't use symlinks in /boot. |
| 11 |
2. I don't use grub, nor any other boot manager. |
| 12 |
3. ...unless you count bootctl, from sys-boot/systemd-boot. |
| 13 |
4. I have the existing ESP mounted on /boot. It belongs to Windows and cannot |
| 14 |
be enlarged beyond 100MB. |
| 15 |
5. I have a small second system on the Gentoo disk called Rescue, so I have a |
| 16 |
multiple-boot system. |

I followed the installation handbook, boot-loader section, to create a UEFI |
| 77 |
boot entry. I followed the syntax precisely, with several variations at |
| 78 |
various attempts. In every case, the UEFI BIOS listed the new entry but |
| 79 |
couldn't execute it. |
| 80 |
|
| 81 |
I want to be shown a list of systems to boot immediately after the POST, which |
| 82 |
I'm sure efibootmgr can't do, so I ran 'bootctl install' to install the code (where?) to give me the ability. That works, though I do remove the directory |
| 83 |
with the 32-hex-digit name, and install my own loader.conf. |
| 84 |
|
| 85 |
The system seems to be stable now. |
