gentoo install finished, wont boot, HELP!!!

hello all,
I just finished installing the latest version of gentoo. I *thought* i followed all of the instructions perfectly, but upon performing the final reboot and removing the livecd, my laptop displays the message , "os not found" .

Please tell me i can use the livecd to fix this, without having to go through the entire install process again... Laptop is gateway mx6930 intel 945gm chipset
I chose lilo for the bootloader and im assuming i set it up wrong or something but i really hope i can fix this with!?out doing everything over again...how can i chroot on to my new filesystem from the cd!

boot the cd, mount the gentoo partitions, enter the chroot is standard procdure for correcting boot problems. summarized (for nominal partition scheme) as:

thank you for porviding me with that little sequence..ive got to write that down. After doing that i opened lilos conf file and noticed it was rife with typos.. :p missing initial slashes mostly, and an ry instead of r6

Then i ran lilo and it worked..although it gave one error "warning: lba32 addressing assumed"

Right now its starting up, taking a while. Ill post any problems..how long shouuld it take to boot now?

if not it will hang up trying to run init.

no stopwatch but 1-2 min.

it did hang, so i followed the instrctions in the link, rebooted, but still hangs in same spot near beginning. when i made the devices console, null, and zero as per the link, both console and zero were already there, so they wernt made. So now im going to rm all three and make them as the linksaid, then reboot again

don't forget the udev link

if from cd with gentoo partitions mounted but not in the chroot:

pertplus · n00b Joined: 20 Jun 2011 Posts: 22

did make the udev link as in the other post, still freezing on "init-early.sh used the greatest stack depth: 5792 bytes left"

Any ideas? Thanks for the help so far..also i just noticed this thread is posted twice...didnt mean to do that

Ill try what you suggested
EDIT: didnt work, confirmed udev was already installed in runlevel sysinit

the picture of the hang is exactly what doing http://forums.gentoo.org/viewtopic-t-880149.html prevents; you may have had a tiny typo.
using rc-update from the chroot may avoid the most likely. While there it would be good to run rc-update show to verify that udev is in fact in the sysinit runlevel.
you could also

ok, so i emerged udev, which downloaded about 20 things so i guess it had to be done. If i try to readd udev to the sysinit it skips it because its already there. do i need to remove it, then add it? At any rate, im still hanging at the same point

Im now going to try remaking the kernel wwith the options you specified

Im using the latest tarball

pertplus,

"os not found" is a message from your BIOS, not Gentoo.
You need to flag exactly one partition on your HDD as bootable. Its traditional to set the flag on / if you don't gave a boot.

Boot the liveCD, run

@neddy Thanks. I'm less ignorant now.

thanks for the reply neddy, but the problem has changed since this post began. I no longer recieve the 'os not found' error, but freeze on boot after lilo dyring gentoo initialization.
i have three partitions, root swap and boot. Only boot is flagged as bootable, as confirmed in fdisk by being the only one with a *. Here are contents of my /etc/fstab from chroot on livecd:

interesting... after adding the options specified by donahue and recompiling, I no longer hang while loading gentoo.

Instead, my computer reboots before I see any of the init text. This continues in a loop.

The good news is im using links to post this instead of my cell phone now! fun !

So either way I guess it has to do with my compile options?

I'm going to look over them again...

pertplus · n00b Joined: 20 Jun 2011 Posts: 22

oops, that was because i forgot I have to emerge lilo again and stuff... also it seems i cant edit posts with links

EDIT** wait, i dont have to emerge it again after all, config is still there after recompile..so why the reboot loop? Im recompiling again with some different options. Of course seeing as i know nothing about this, any improvement in the situation will be purely luck based... And i still cant edit post with lniks

wow, i finally got through the boot! Could have been a couple things. I added ext4 support and the option where it says something like 'treat ext3 as ext4'. Also i noticed the compiled image was placed in /x86/ not /i386/ as in the manual.Also, when i tried to copy the compiled image to /boot/kernelname , it wouldnt let me, saying it was read only. Then i did umount /dev/sda1 and mount /dev/sda1 /boot (in chroot environment) and the cp then worked. The i exit' reboot and it booted!

But now, trouble. I have no 'iwconfig' command, and no net-setup, .....EDIT i did emerge wireless-tools on the live cd in chroot but still cant do net setup, wlan0 isnt a device now, apparently (driver shows up in lscia)

DONAHUE · Posted: Tue Jun 21, 2011 11:31 pm Post subject:

net-setup is only available in the cd system.
see http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4

wireless-tools only does WEP

if you use WPA, you will probably want to emerge wpa_supplicant and get that set up
you should also emerge net-wireless/iw, as that's needed for the nl80211 way of configuring things from what i understand

Well, it took 30 some odd hours, infinite recompiles and a whole lot of brain-twisting rage, but I FINALLY got everything to boot with wireless working. I'm learning a lot..this is all very fascinating and I could see myself becoming..engulfed

My next step is to set up a window system. Gonna try Enlightenment because I liked how it looked on the pentoo cd. Hopefully wont have to recompile again for it..

Thank you so much everyone for your help!! You'll be hearing from me again..probably very soon
