when i bought my laptop it came with ubuntu pre-installed on it and the grub menu was hiddin , but u can activate it by shift .
now i have removed that ubuntu and installed new ubuntu , and i found that grub menu appear even when i have only ubuntu , i have hidden the menu by removing the # before " GRUB_HIDDEN_TIMEOUT=0 "

now what i want is :

(1) : i want to make the start up very fast . ( i wait something like 10 sec before the ubuntu logo appear and after that with 1 sec the login screen appear )

(2) : i would like to change the debian photo that appear on the back of the grub !!! what bring it there any way

(3) : the recovery partition is not detected

...perhaps you can just uninstall grub, since you are using only one os

You need grub even if only booting one system as that is the boot loader.

You show no recovery partition, but show the Dell utilities partition which often just has some tools specific to Dell and usually only with Windows.

I do not use back ground images but this explains how.

Speed depends a lot on what is loading. If it was Ubuntu pre-installed then the vendor may have optimized it to not load nor search for devices that your system does not have and maybe other settings. For instance I turned off bluetooth on my desktop as I do not have that. But you really have to know your system. What version was it before. If a lighter weight version of Ubuntu it also may have been quicker.

Did you document old system and its configuration?

i tried to remove the DIAG and LBA flags , but still the same .
how can i be sure that there is nothing making delay for the start up
could the old IPL and the new IPL mixed ? or new IPL is written once installed new grub ?
i had the recovery detected before on the last grub before i install 12.04 . how to detect it ?

about the debian photo , i think if i installed the grub from live cd . it will goes back to default .
