Started PC but stuck at grub?


I started up my gentoo laptop this morning to look something up but I am stuck at a grub terminal with no idea where to go from here.

I didn't install a new kernel since the day I installed the gentoo distro which was a few months ago.

The kernel name is: kernel-genkernel-x86-2.6.34-gentoo-r7

The initramfs name is: initramfs-genkernel-x86-2.6.34-gentoo-r7

Both are located in /boot

I used genkernel to compile and create the kernel and the initramfs.

I remember portage saying I needed to update like "30" config files in /etc but I had no idea which ones to update or what to put in them.

Is there a reason why grub... forgot where my kernel was?

Any idea how to fix it?

You probably could reinstall GRUB:

Code:
[root@gentoo-livecd:~]# grub-install /dev/sda && update-grub

I considered that already but the problem is, The laptop won't boot from a CD because the last technician I brought it to locked the bios.

Its not technically locked because it doesn't require a password but I can't change anything in the BIOS and it says its "configured by the OS".

Whatever that means.


All I have to work with is the grub terminal.

Is it possible to just tell grub where the files are and then boot it?

(hd0,0) or /dev/hda1 is where the files for the OS are located.

Also if you know what the "configured by the OS" in the BIOS means then please tell me as I have been puzzled by that for quite a while now.

hi

there are 2 issues but I would like to suggest we solve the firmware=bios issue first. BTW the grub issues are best dealt with by a rescue cd and oops you can't use one hence the bios issue comes first

1) Have you rung the tech for bios password?

if he can't remember, ask him to reset it free heh heh

2) Otherwise, follow this advice at own risk....but I have it done it myself.

a) turn off device and if you have an earthed plug....turn off at wall but leave it plugged in...if not sure remove plug from wall socket.

b) buy a anti-static wrist strap from a electronics store they cost about $10

if not interested.....stand still and use the back of your hand to discharge any static electricity from your body onto the power supply metal case or the metal case.

c) remove battery from bios area and leave out for 30 seconds.insert battery....reboot to test if password now gone....if not go to d)

d) if (c) failed.....remove battery and do not wait 30 seconds but get a piece of metal.....a screwdriver ....spanner...etc.....and touch the middle of the battery compartment to its side......which shorts.....that battery holder....insert battery and reboot.

-----
if it worked, you will also need to reset the date and other things......so write down....ALL of your current settings please or digital photos

good luck

1: I tried but the computer technician was a total jerk. He didn't even fix the computer problem and still charged me for it.

2: I can't even get to the bios battery without removing the entire motherboard on the laptop. If I do that the odds of me getting it back together and working are very slim. The actual laptop battery has 10 pins so.... yeah...

Its a toshiba satellite A45-S121 laptop.

The bios states that there is NO password set but I can't edit anything.

It boots in this order: HDD, FDD, CDROM, LAN

I would try bios backdoor passwords except it never asks for one.

Hello,

Not sure if this will help or not but some Toshiba laptops have a additional boot menu. When the Toshiba splash screen is displayed down at the bottom you might have some options such as press C to boot from cdrom or press f12 to enter boot menu. you have to be fast and these are only temporary settings good for that boot only. best of luck to you

take care,
Sean

hi

Section...BOOT Order

try this way to get into bios..model is exact match

Escape + delete + F1 as per
http://www.linuxquestions.org/questi...n-grub-825133/

then try F12 ....thanks for helping Void13


SECTION bios battery shorting

then try this at own risk of course
http://www.laptop-repair.info/toshib..._password.html

more extreme....more risky and wrong model number is this link
http://www.flickr.com/photos/2264118...n/photostream/

but your motherboard site should show you the correct way to get into bios.

2) I am still thinking if its merely a matter of getting boot order....then try that first.....only try shorting as a last resort and other sites may be able to help with your exact model please

No it doesn't say press any key for anything.

It just has the toshiba logo for a second and then boots the first HDD.

F12 doesn't do anything. I have to press DEL + ESC + F1 to enter the bios.

"Escape + delete + F1" gets me into the bios but I still can't edit anything.

F12 doesn't do anything at all.

"http://www.laptop-repair.info/toshib..._password.html"

Big problem with this, the laptop doesn't have a Floppy drive and it doesn't have a parallel port.

That and they don't have a list of the specific model of this particular laptop.

I was kind of wondering what the possibilities of a bios root kit would be..

I am thinking about bringing the laptop to my Computer Service Technician teacher here in a couple days to have him look at it.

He mentioned bios viruses that could lock a person out of the bios. I have never heard of such a thing.

However this question is still unanswered.

hi

You can not use a rescue cd or bootable USB until you can change the bios boot order.

You say you can't change it after getting in....fair enough....then short the appropiate jumpers at the battery area, unless it is not asking for a password?

Can you be more explicit....some changes need a bios password while to get past a more paranoid setting....bios password is needed for any boot up.

good luck

I don't know which jumpers to short together. It doesn't ask for a password anywhere.

Sadly though Toshiba doesn't release motherboard information for my laptop. Or at least I couldn't find any. :-/

There is NOTHING I can change in the bios. I can look but I can't edit.
