[SOLVED] Devaun Excalibur not booting after instilation

Hello,

I have recently been trying to install Devaun Excalibur from the live desktop usb and have been running into a problem. I go though the instillation process and have no problems but after finishing and rebooting the computer it tells me that there is no bootable device found. When I go to check the bios It shows nothing. I already have secure boot off.

Any help would be appreciated!

Re: [SOLVED] Devaun Excalibur not booting after instilation

Sometimes the bootloader doesn't install correctly. If you know how to chroot, you could boot the live, chroot into the installed system and install grub and then run update-grub to get a boot menu. I left a few steps out of this.

Easier method might be to get the netinstall iso, boot into Rescue mode from the boot menu, and reinstall the bootloader. Those are all menu choices.

For more detailed instructions, we need to know if you're booting uefi or legacy bios (CSM) and whether or not you have a separate partition for /boot.

Thank you. I am using UEFI and I am not using a separate partition for boot. I have SDA1 for esp/boot, SDA2 for Linux Swap, and SDA3 for the filesystem.

I've found, in the past, that the 'live' installer usually needs to be connected to the internet so that it can download the necessary files.

I have usually had the wifi set up on the live when I installed it. Does it need Ethernet?

I installed Devaun via the Netinstall iso's automatic instillation mode and it works perfectly now. Thanks!

I'm glad you got it installed. The netinstall iso gives you some software choices. The live install just gives you whatever is in the iso.

@Camtaf: The live installer does not need internet to work and does not download anything. If you notice that something is missing for it to work, let me know and I'll add it to the next build.
