Re: Need to boot from CD and delete a file on the hard drive
Hello All -- SUMMARY: I changed a configuration file and now I can no longer boot from my hard drive (but I can still boot from the CD). I would like to boot from the CD and undo my change to the configuration file -- but when I boot from the CD it automatically launches the install program. Is there a way to boot from the boot CD and get a shell and make a change to a file on the hard drive? (I got an emergency shell after booting from the CD -- but I can't figure out how to access my hard drive filesystem from it.) DETAILS: I was trying to set up a serial console using the instructions here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup. html I typed the following at the prompt: # echo 'console=comconsole' /boot/loader.conf then unplugged my regular keyboard and tried to reboot -- but the machine now freezes on bootup. I now want to boot from a CD and remove the file /boot/loader.conf from the hard drive. Then I should be able to boot normally again from the hard drive. I went into the BIOS and booted from the CD and this put me in the install program. I don't want to install everything again -- I just want to boot up from the CD and execute the following command at the prompt: # rm /boot/loader.conf After booting from the CD, I found a command in the install program to enter an emergency shell and accessed this shell by hitting ALT-F4 -- but if I do an rm command in this emergency shell, it doesn't apply to the filesystem on the hard drive -- it applies to the CD. I need to delete the file /boot/loader.conf while booting from the CD. Is there any way to fix this without installing FreeBSD all over again? I've never done this...but... Reboot the computer from the CD, Look for the message: Hit [Enter] to boot immediately, or any other key for command prompt. Booting [kernel] in 9 seconds... At that point press any other key. You should then be able to mount your /boot partition and delete the file, however, you may have to look around on the CD for the appropriate commands. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Apologies for replying to my own msg, but I just 'had' to try what I told you, and there are no tools such as 'mount', or 'rm' available when booting to a command prompt as I said. I tried the Emergency Shell from the CD, same thing. Sorry I sent you on a wild goose chase, but I'm sure you'll get the correct answer soon. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Scott Alexander The option you are looking for is fixit from the install disk menu. This'll get you a command prompt. You will have to manually mount the partion that boot is on then you can delete, rename, edit, etc the file in question.

I found this link explaining the process: http://www.freebsd-corp-net-guide.com/technotes/fixit.html Good, but I think it depends on the FreeBSD version. I think, starting with 5.xx the fixit is all on disk one and you don't need disk 2, but for 4.xxx and earlier you do. jerry ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
