BOOT EFI How To Restore?

Hi,

How to restore my efi boot ? I did a debian (Boot0003 debian) install on usb key, no issue with the key.

Now I have to select in the bios the disc to boot, the manjaro boot screen appears, I select the wished manjaro linux and then a blinking underscore appears on the top left, I have to wait a long time before the os boot… I’m not a power user, thanks for your help in advance :slight_smile:

Thanks for your reply and the tips links.

What I did ? I booted an own Manjaro iso image, did a new boot efi install, keep the other /wished partitions (available during the install process for each partition, nice feature :-), I deleted the boot efi partition, created a new one, and installed it.

Result ? A booting OS as wished, that’s all. The easiest way to repair a boot/efi with a GUI, without reinstalling the entire OS, but just the boot.

I firstly would remove plymouth, to see where it stuck.

I don’t understand why you reinstall Manjaro when you only want to restore your EFI.

You can also use Timeshift, when you have a snapshot… if you don’t want to use install-grub or grub-install.
