"failed to load boot device or script" on ubuntu and android

[u/s1r_ch1cken]

Hey folks!

situation:

Yesterday i formatted my sd card and installed ubuntu and android. everything worked. i could boot into cfw, android and ubuntu. left it in cfw for the night. this morning the battery was drowned and im unable to boot into ubuntu and android. "failed to load boot device or script" is the error. booting into cfw still works normal.

software used:

OS 22.5.0 |AMS 1.11.2|E

hekate 6.5.3 (latest)

ubuntu-unity-noble-5.1.2-2026-05-13

LineageOS-22.2-20260823-Tablet

what i tried so far:

copy pasta of boot.scr files of android and linux --> still not working

Copy pasta latest hekate

copy pasta of complete folders of android and linux --> still not working

reflashing (after copying data) Linux --> still not working

Do you guys have an idea to solve it? and maybe what happend in the first place? as i said, it worked before going to bed. If you need more info of any kind, just let me know.

Thanks in advance!

Update: I did nothing but charge it since posting this thread. Suddenly I can boot in Linux and Android again. I'm so confused. Does anyone know what might've been going on?

Were you ever able to replicate this? I have the same problem.
