EFI Variables Installation Errors ​

1. Failed to Create EFI Boot Entry ​

Context ​

The installer displays a warning about being unable to create an EFI boot entry, though installation can continue after dismissing the alert.

Symptom ​

1. Access the terminal (Ctrl+Alt+F2) and examine /tmp logs.

2. storage.log reports "no space left" errors.

   

3. The /sys/firmware/efi/efivars/ directory contains an excessive number of boot entries.

Possible Causes ​

The BIOS variable storage area has reached capacity, preventing new EFI boot entries.

Resolution ​

Clear the BIOS variable cache.

2. Mount Error 32 ​

Context ​

The installer fails with "mount failed: error 32" during operation.

Symptom ​

The error occurs when /sys/firmware/efi/efivars/ is mounted.

1. Access the terminal (Ctrl+Alt+F2) and examine /tmp logs.

2. storage.log reports space allocation failures.

   

Error messages suggest potential file system corruption (bad superblock) in efivarfs, requiring BIOS-level investigation.

Possible Causes ​

Hardware-related BIOS abnormalities or corrupted variable storage in flash memory cause UEFI variable service failures, leading to mount errors during OS installation.

Resolution ​

Re-flash the BIOS firmware.
