how to delete boot.efi & bootX files

Hey experts, I deleted a complete Time Capsule backup from an ext. hard drive, as I have no need for the backup & drive. Unfortunately it can't delete two files: boot/efi and bootX. They are locked and when I do a 'get info' on them, the actual locked box is ticked but greyed out..... has any one got any ideas how to unlock them, so I can delete them?

iMac PowerPC G5, Mac OS X (10.6.1)

Hi,

maybe the file have the uchg flags, that means the file is unchangeble "User immutable flags", you can view the flags from terminal app with "ls" command, show the output like this:

bash$ ls -alO
-rw-r--r-- 1 root wheel uchg 319152 14 Nov 17:52 boot.efi

Try to login with an admin user with "su" command

bash$ su - <admin username>

Go to the directory contain the file "boot.efi"

bash$ cd /Volumes/<volume name>/<some other dirs>

and remove the flags with:

bash$ sudo chflags nouchg boot.efi

Now try to remove the file with:

bash$ rm -rf boot.efi

Enjoy...

+##Now type the command after the "$", in bold, and change "admin username" with your, and the password##+

hostname:~ <your username>$* su - <admin username>*
Password:

+##Change here the name of your volume "<volume name>"##+

hostname:~ <admin username>$ *cd /Volumes/<volume name>/*

+##With this command show the flags of you file note the "uchg" word##+

hostname:<Volumes Name> <admin username>$ *ls -alO boot.efi*
-rw-r--r-- 1 <admin username> admin uchg 0 May 13 14:27 boot.efi

+##Remove the flags##+

hostname:<Volumes Name> <admin username>$ *chflags nouchg boot.efi*

+##Note the "-" where was "uchg"##+

hostname:<Volumes Name> <admin username>$ *ls -alO boot.efi*
-rw-r--r-- 1 <admin username> admin - 0 May 13 14:27 boot.efi

+##Remove the file##+

hostname:<Volumes Name> <admin username>$ *rm -rf boot.efi*

+I hope you understood, and sorry for my english...+
