while I was using a live cd, I accidentally deleted some files on the hard drive, including apparently the init file. The fact is that linux doesn't start anymore (kernel panic).

I tried to install Ubuntu on a USB HDD on my Macbok Pro 5.3. Everything seemed to be fine, but while rebooting the computer, OSX doesn't start anymore. So, I would say I erased the boot sector of the internal HDD or something similar but I'm not an expert. My internal HDD seems to be fine: One 200 MB FAT32 partiton partition labeled EFI and with the boot flag, One HFS+ partition for the system. I tried to boot with the Snow Leopard DVD and run the Disk Utility to make a "repair". The repair was fine, but the Mac still doesn't boot anymore. (Forget Ubuntu, it's only OSX related, I'll try again Ubuntu only when I'll be able to boot OSX again).

View 8 Replies View RelatedI have recompiled a few kernels, but all on 32bit systems so not sure if that has anything to do with it.
Running Arch Linux 64bit, most recent version.

Code:
My first thoughts was that it might be my grub bootloader configuration, so had a big play around with that but it didn't fix it. Also made sure support was built for filesystems. However almost all that Fstab mounts are ext3 anyway, and certainly the root and /boot are. Now thinking it may be a memory error so will run a check when I shutdown.

Kernel panic - no syncing: Attempted to kill init!
1. Does minimum installation not drop on a kernel or initrd with ext3 support? I can't imagine that's true, but have to ask.
2. The USB stick is single partition ext3. Maybe there is some limitation specifically related to USB stick booting that requires boot to be FAT16 or FAT32? Except the CentOS 5.5 installer refuses to let me install on either FAT.
3. How can I do the equivalent of lsmod on a linux installation that will not boot? i.e. I have CentOS x86_64 running in VirtualBox, I can plug the USB stick in there, so how do I get information on the USB stick's kernel and initrd if I can't boot from it?
4. Is it possible to rebuild the i386 based initrd on this USB stick, when the computer is not booted from that stick, with a system that's x86_64 based?
System Info:
Dell Latitude i686 Laptop which has run CentOS 5.5 and Fedora 12,13,14 in the past, and boots from Fedora 14 Live CD transferred to a USB stick. So I know USB booting is possible on this machine, and this stick.
The process of creating the stick:
CentOS 5.5 i386 on a USB stick. Old Dell i686 laptop which has previously run CentOS 5.5 installed from DVD, and has successfully booted from this same USB stick holding transferred Fedora 12,13,14 Live CDs. CentOS 5.5 was installed onto the USB drive directly by the CentOS 5.5 DVD installer (running virtualized in VirtualBox 4.02 on Mac OS X 10.6.5.). No errors or complaints during installation.
For whatever reason, the installer did not do some things correctly. First Grub wasn't working correctly, I got that sorted out and have the Grub+CentOS splash screen, it finds vmlinuz and the initrd, and then I get a kernel panic.
Ext3 was built into the kernel and that's why I'm getting this message. I do not know how the installer would have dropped a kernel or initrd during instalation that that don't contain such a basic thing that obviously comes in linux kernel 2.6.18-89 EL.
I am running an Hp Pavillion dv6000 with the Broadcom card that never seems to work for Linux. I recently talked with my friend who said he found a way to get it work.following his instructions I opened Synaptic and checked the package bmcwl-kernel-source to be installed.I went through the process of it all and it said it had install successfully. I restarted the computer and when I tried to enter my operating system I got this error "Kernel panic - not syncing : VFS : Unable to mount root fs on unknown - block(8,1)"
I have previous versions of Linux on my computer so I can still get in to those if need be but I don't know how to undo what I did or why it isn't working for that matter. Does anyone have any ideas as to why I am getting this error and how I can fix it?
this is what i did i downloaded the latest stable kernel archive from kernel.org and extracted the archive into the download directory (i don't think that matters though) then i downloaded and installed the ncurses archive (needed for menuconfig) then i opened a terminal and navigated to the directory that was extracted from the archive and issues the floowing commands

View 5 Replies View RelatedIm am building a Linux distro. It will be very tiny and fast.
I only have a minimal linuxkernel (bzImage) who is 1,2 mb big. And then I have Busybox who is 174,6 kb big.
The commands in busybox is: cd, ls, mkdir, rmdir, wget, httpd, clear, rm, poweroff, halt, reboot, fdisk, mount, umount, free, and cp.
When I compiled the kernel i use initramfs/initrd function and point it to a folder where initrd/initramfs source is.
The kernel works OK with others initramfs/initrd files. But not with my own.

Here is how the end of the kernelcomplie look like.
Quote:
Here is my init file who is the initrd/initramfs source.
Quote:
The initramfs folder contains "bin" (folder) and "init" a file. No more.
The problem is that the kernel cannot find/read init file.
I use gentoo linux and some minutes ago I thought to upgrade my kernel version. I had 2.6.36-r5 and I want to set 2.6.37-r4. After merging gentoo-sources I did this:
# cd /usr/src/linux
# make menuconfig
# make && make modules_install
# mount /boot
# cp arch/i386/boot/bzImage /boot/bzImage-2.6.37-gentoo-r4
# module-rebuild populate
# module-rebuild rebuild
At the end I changed the /boot/grub/grub.conf file. The last two commands are for reinstall modules that are not included in the kernel source. After rebooting the system this is what it printed out and stop loading.

View 2 Replies View RelatedI am using Ubuntu 9.10. Since a few days my I cannot boot anymore with the newest kernel (2.6.31-20.31). Instead I get a menu with a menu that lets me boot in recovery mode or boot from previous kernels (2.6.31-19).
In recovery mode for 2.6.31.20 it hangs at: Waiting for root file system. It boots just fine with kernel 2.6.31.19 except that apache and cups have to be reinstalled after every reboot. Everthing else seems to work without any problem.
Is there a way to do a system recovery, like in Win XP, going back to a system state from before the problems started?
Yesterday I installed Fedora 15 instead of Ubuntu 11.04. I have nvidia card, so I've searched for nvidia driver installing howto and found it on this forum [URL]. But after updating kernel -
Code:
yum update kernel*
(now it's latest - 2.6.39) - and rebooting Fedora didn't start. I even don't know if it's something with GRUB because It automatically loads Fedora and I can't know whether it's its problem. When I try to start Fedora, I just see black screen with blinking underline cursor at the top left of the screen and it's the first and the last I see except laptop splash screen. I have Asus F50SV (Nvidia GT120M). By the way, I've tried to install nvidia drivers manually and xorg.conf became broken. I've edited it and now it like this:

I have a server with Debian on it that I regularly reboot after upgrades. Sometimes (on schedule) fsck will check a disk when the computer is booting. With the exception of sitting in front of the console to observe the fsck, how can I determine the difference between a problematic halt and an fsck (besides waiting out the fsck, hoping it is an fsck)?When I send the computer down to reboot, I will usually have a terminal window open pinging the computer so I know when it has come back up. My first thoughts drifted to fantasizing about hacking fsck to respond to pings with some special magic byte so you could tell via ping that a computer was fsck-ing, but I'm thinking there have got to be easier ways..

Yesterday I decided to dual-boot windows 7 and Ubuntu 11.04. I successively instaled Ubuntu the first time using a flash drive. However, I found that I had made the partition for Ubuntu way to large. Having no idea what to do, I messed around with the partition sizes. Through a series of... mistakes, I deleted the two (the main space and swap space) linux partitions. When I restarted my computer I got the "partition not found" error. So from there, I burnt another ubuntu disk, (the flash drive I used had been reformatted for use on an Xbox) I am able to boot a live version of ubuntu on my computer. However, when I go to install Ubuntu, something goes wrong. After copying all the files, it goes into kernel panic about not syncing, and freezes.
I had looked up some advice on the web, and they said that it might be a memory error. However, Ubuntu 11.04 does not have the memtest86 or whatever, (at least that I could find) So I took out the smallest RAM stick (1 gig, leaving the laptop with 2 gigs of RAM) and it still freezes.
I included the story to see if I did something wrong with any of my steps that may have permanently done something bad to it.I know it does not sound like it, but yes, I only installed Linux yesterday, therefore, still a newb.
how to get linux onto an old laptop (dell inspiron 2600, 1GHZ, 120MB RAM). the cd drive doesn't recognize CD's anymore and in boot menu, "Setup Utility" the usb drives aren't recognized. the usb drive or pen drive boots in another desktop just fine. i need to somehow install xubuntu or crunchbang or something lite but must do it using net install. i see lots of tutorials but they are either too complicated or unknown source, like "inslux." and not too complicated of a process. I'm a "techie-tard," i guess. also, i'd like to suggest a new "sub-forum" in "distribution" forum, Called "General Distro."
