# Fedora not installing bios update
Published on 29 March 2024

My Dell Precisin 5530 laptop was not installing the bios update. In the GNOME GUI it was not showing any error and kept prompting to do a reboot.
On the CLI when doing a fwupdmgr update I was getting the following error:

[gokhanorhun@fedora ~]$ fwupdmgr update

/boot/efi does not have sufficient space, required 66.3 MB, got 65.2 MB

Solution

Apparently this has to do with having a dual boot with Windows and the /boot/efi partition was only 96MB.

I had to temprary move /boot/efi/EFI/Microsoft and /boot/efi/EFI/Dell to another location and then run the fwupdmgr update again.

An update requires a reboot to complete. Restart now? [y|N]: 

After the update was successful I moved the /boot/efi/EFI/Microsoft and /boot/efi/EFI/Dell back to their original location.
